Antecubital Fossa Solitary Osteochondroma with Associated Bicipitoradial Bursitis Thu, 27 Aug 2015 12:26:51 +0000 http://www.hindawi.com/journals/crior/2015/560372/ Antecubital fossa lesions are uncommon conditions that present to the orthopaedic clinic. Furthermore, the radius bone is an uncommonly reported location for an osteochondroma, especially when presenting with a concurrent reactive bicipitoradial bursitis. Osteochondromas are a type of developmental lesion rather than a true neoplasm. They constitute up to 15% of all bone tumours and up to 50% of benign bone tumours. They may occur as solitary or multiple lesions. Multiple lesions are usually associated with a syndrome known as hereditary multiple exostoses (HME). Malignant transformation is known to occur but is rare. Bicipitoradial bursitis is a condition which can occur as primary or secondary (reactive) pathology. In our case, the radius bone osteochondroma caused reactive bicipitoradial bursitis. The differential diagnosis of such antecubital fossa masses is vast but may be narrowed down through a targeted history, stepwise radiological investigations, and histological confirmation. Our aim is to ensure that orthopaedic clinicians keep a wide differential in mind when dealing with antecubital fossa mass lesions.

Atraumatic Occult Odontoid Fracture in Patients with Osteoporosis-Associated Thoracic Kyphotic Deformity: Report of a Case and Review of the Literature Wed, 26 Aug 2015 14:04:47 +0000 http://www.hindawi.com/journals/crior/2015/301858/ Anderson type II odontoid fractures are reported to be the most common injury of the odontoid process in patients over the age of 65. However, atraumatic occult Anderson type III odontoid fractures have been rarely described and remain a diagnostic challenge. In the present report, we illustrate a 78-year-old female with osteoporosis-associated marked thoracic kyphotic deformity who developed atraumatic Anderson type III occult odontoid fracture and raise awareness of this condition. Anteroposterior and lateral standard radiographs of cervical spine failed to disclose odontoid fracture. Magnetic resonance imaging demonstrated intensity changes of the axis. Subsequent computed tomography clearly demonstrated Anderson type III odontoid fracture. Conservative treatment achieved complete bone union without neurological deteriorations. At 3-year follow-up, the patient was doing well without neurological and radiological deteriorations. Even if the patients have no traumatic event, we have to keep odontoid fractures in our mind as one of the differential diagnoses when we encounter elderly patients with neck pain, especially in patients with osteoporosis-associated marked thoracic kyphotic deformity.

Supraspinatus Intramuscular Calcified Hematoma or Necrosis Associated with Tendon Tear Wed, 26 Aug 2015 09:18:37 +0000 http://www.hindawi.com/journals/crior/2015/496313/ Introduction. Rotator cuff intramuscular calcification is a rare condition usually caused by heterotopic ossification and myositis ossificans. Case Presentation. We describe a patient with voluminous calcified mass entrapped in supraspinatus muscle associated with corresponding tendon tear. Histological examination corresponded to a calcified hematoma or necrosis. Patient was surgically managed with open excision of the calcified hematoma and rotator cuff arthroscopic repair. At 6 months, supraspinatus muscle was healed, and functional outcome was good. Discussion and Conclusion. We hypothesized that supraspinatus intramuscular calcified hematoma was responsible for mechanical stress on the tendon. This association has never been described.

Pyoderma Gangrenosum Mimicking an Infected Wound following Dynamic Hip Screw Fixation Mon, 24 Aug 2015 07:11:25 +0000 http://www.hindawi.com/journals/crior/2015/571472/ Pyoderma gangrenosum (PG) is an inflammatory ulcerative neutrophilic dermatosis that can occur following skin trauma. The correct diagnosis is not often made immediately as the condition can mimic an infective appearance. This leads to delays in the appropriate management of high dose steroids. Although debridement can offer aid in resolving lesions, this is contraindicated in the acute phase as this can cause acceleration of the pathogenic process. Biopsy of the lesion does not offer a definitive diagnosis; therefore suspicion must be maintained as the diagnosis is ultimately a clinical one. Any postoperative pustular ulcerative lesion not improving despite antibiotic therapy that also yields negative bacteriological and fungal studies should lead to consideration of this diagnosis. We document the first case of PG developing following intertrochanteric femur fracture fixation using dynamic hip screw. Metin Nizamoglu Copyright © 2015 Metin Nizamoglu. All rights reserved. Simultaneous Bilateral Rupture of the Triceps Tendon in a Renal Transplant Patient Thu, 20 Aug 2015 14:04:37 +0000 http://www.hindawi.com/journals/crior/2015/903690/ The unilateral rupture of the triceps brachii tendon is a rare lesion representing 1% of all tendon injuries. The most common causes are the result of a contraction against resistance (especially weightlifters) and direct trauma. It has also been associated with systemic diseases such as diabetes mellitus, chronic renal failure, secondary hyperparathyroidism, and use of systemic corticosteroids. Simultaneous bilateral rupture of the triceps tendons is less frequent and has been described in association with chronic metabolic disorders, especially in those patients on hemodialysis. This paper presents a case of bilateral triceps tendon rupture of a 36-year-old woman with renal transplantation secondary to chronic renal failure. Early surgical repair was performed using a bone tunnel technique with a nonabsorbable suture. Clinically active extension with 135 degrees of range of motion was achieved. Ezequiel E.

Percutaneous Endoscopic Discectomy via Transforaminal Route for Discal Cyst Wed, 19 Aug 2015 15:28:38 +0000 http://www.hindawi.com/journals/crior/2015/273151/ Background. Discal cyst has been identified as a rare cause of low back pain and radiating leg pain. The pathogenesis and management of this condition are still debated. The largest number of reported cases had undergone microsurgery while very few cases have been treated with percutaneous endoscopic discectomy (PED). Methods. An 18-year-old boy complained of low back pain radiating to right leg after a minor road traffic accident. Diagnosis of a discal cyst at L4-L5 level was made based on magnetic resonance imaging (MRI). Despite conservative management for 6 months, the low back pain and radiating leg pain persisted so surgical treatment by PED was performed under local anesthesia. As the patient was a very active baseball player, his physician recommended a minimally invasive procedure to avoid damage to the back muscles. Results. The patient’s low back pain and leg pain disappeared immediately after surgery and he made a rapid recovery. He resumed mild exercise and sports practice 4 weeks after surgery. Complete regression of the cystic lesion was demonstrated on the 2-month postoperative MRI. Conclusion. A minimal invasive procedure like PED can be an effective surgical treatment for discal cyst, especially in active individuals who play sports. Subash C.

Acute Popliteal Artery Occlusion after Revision Total Knee Arthroplasty Wed, 19 Aug 2015 08:57:03 +0000 http://www.hindawi.com/journals/crior/2015/672164/ Acute arterial occlusions are a rare complication of total knee arthroplasty (TKA). However, in revision TKA, the risk of such complications is higher and these complications can lead to amputation if not adequately treated. We describe a case of acute popliteal artery occlusion 4 hours after second revision TKA in a patient with a history of several surgical procedures because of periprosthetic infection at a previous hospital. Revascularization was achieved via bypass grafting and amputation was narrowly avoided despite time lag after symptom onset to revascularization. In this case, it was possible that the arterial disease that accompanied the vascular endothelium injury such as pseudoaneurysm had existed since the previous surgery at another hospital and was destroyed by the surgical procedure, which led to the formation of thrombosis and arterial occlusion. Preoperative evaluation of the arterial condition should be considered to avoid acute arterial occlusive disease, especially in patients who had several previous surgical procedures.

The Power of a Soccer Ball: A Traumatic Open Finger Dislocation—A Rare Case Presentation Sun, 16 Aug 2015 12:23:32 +0000 http://www.hindawi.com/journals/crior/2015/698928/ Proximal interphalangeal joint dislocations are injuries observed frequently and caused by axial loading on the finger in the extension. In this paper we present a traumatic open finger dislocation due to a ball hitting a wrestler. It was successfully treated with reduction and the volar plate and collateral bond fixation were applied with absorbable sutures.

Complex Scapular Winging following Total Shoulder Arthroplasty in a Patient with Ehlers-Danlos Syndrome Wed, 12 Aug 2015 11:32:14 +0000 http://www.hindawi.com/journals/crior/2015/680252/ This is a unique case of a female patient with features of classical and hypermobile types of Ehlers-Danlos syndrome (EDS) who developed complex scapular winging from spinal accessory and long thoracic neuropathies. These neurological problems became manifest after an uncomplicated total shoulder arthroplasty (TSA). The patient had a complex postoperative course with extensive work-up in addition to revision shoulder surgery and manipulations to treat shoulder stiffness. It was eventually suspected that the periscapular nerve impairments occurred during physical therapy sessions after her TSA. This interpretation was further supported by genetic evidence that, in addition to EDS, the patient had an unrecognized genetic propensity for nerve palsies from stretch or pressure (“hereditary neuropathy with liability to pressure palsies” (HNPP)). By two years after the TSA the neuropathies had only partially improved, leaving the patient with persistent scapular winging and shoulder weakness. With this case we alert surgeons and physical therapists that patients with EDS can have not only a complicated course after TSA, but rare concurrent conditions that can further increase the propensity of neurological injuries that result in compromised shoulder function.

Profunda Femoris Pseudoaneurysm following Total Hip Arthroplasty Revision Mon, 10 Aug 2015 13:01:25 +0000 http://www.hindawi.com/journals/crior/2015/301949/ Vascular injuries following total hip arthroplasty (THA) are very rare, with pseudoaneurysm being a small subset. We report a case of profunda femoris artery (PFA) pseudoaneurysm in a 61-year-old male following a posterior approach revision left THA. Presentation involved continued blood transfusion requirements several weeks postoperatively. Diagnosis of the pseduoaneurysm was made by contrast CT of the lower extremity, with confirmation via IR angiography. Successful embolization was achieved with selective coiling and Gelfoam. Presenting complaints of such complications are often vague and therefore lead to delayed diagnosis. Causes of such complications are not completely understood, particularly with PFA injuries in THA. Possible mechanisms are discussed in this paper. Vascular complications following THA can be difficult to diagnose. High suspicion in the setting of continued postoperative pain or bleeding may allow prompt diagnosis and avoidance of serious limb-threatening complications.

Correction of Length Discrepancy of Radius and Ulna with Distraction Osteogenesis: Three Cases Mon, 10 Aug 2015 12:03:38 +0000 http://www.hindawi.com/journals/crior/2015/656542/ Objectives. The aim of the study was to investigate the results of patients with isolated length discrepancy between ulna and radius who underwent distraction osteogenesis with unilateral external fixator. Material and Methods. A patient with ulna shortening due to multiple enchondromatosis, a patient with ulna shortening due to ulnar club hand, and a patient with radial shortening due to radial club hand were included in the study. The patients underwent ulna and radial distraction osteogenesis with unilateral external fixator. Range of wrist and forearm motion, deformities, and length discrepancy of ulna and radius were compared at preoperative and postoperative. Results. Duration of external fixation and followup were 2.6 and 23.3 months, respectively. Mean distraction osteogenesis was 1.66 cm. No patient reached the length of normal side. Range of rotation of forearm was increased by 15°. Range of ulnar-radial deviation was increased by 21.6°. Deformity of 15° at patient with multiple enchondromatosis was corrected. Conclusion. Isolated ulna or radius shortening may reduce with distraction osteogenesis by unilateral external fixator to prevent serious deformity.

An Unexpected Complication of Hip Arthroplasty: Knee Dislocation Mon, 10 Aug 2015 06:36:25 +0000 http://www.hindawi.com/journals/crior/2015/294187/ An increasing number of patients with hip fracture have been seen with osteoporosis associated with osteoarthritis. Although knee dislocation is related to high-energy trauma, low-grade injuries can also lead to knee dislocation which is defined as “ultra-low velocity dislocation.” The case reported here is of an 82-year-old patient who presented with a left intertrochanteric hip fracture. Partial arthroplasty was planned because of osteoporosis. In the course of surgery, degenerative arthritic knee was dislocated during the hip reduction maneuver with the application of long traction. The neurovascular examination was intact, but the knee was grossly unstable and was dislocated even in a brace; thus a hinged knee prosthesis was applied nine days after surgery. The patient was mobilized with crutches after the knee prosthesis but exercise tolerance was diminished. In conclusion, it should be emphasized that overtraction must be avoided during the hip reduction maneuver in patients with advanced osteoarthritic knee.

Delayed Hypersensitivity Reaction: An Increasingly Recognized Complication of Metal-on-Metal Total Disc Replacement Sun, 09 Aug 2015 13:40:30 +0000 http://www.hindawi.com/journals/crior/2015/416548/ We report the case of a 32-year-old woman who presented with pain recurrence 20 months after she underwent a C5C6 metal-on-metal total replacement. Plan radiographs demonstrated a modification of the shape of the vertebral bodies making the prosthesis more protruding. Then, infection has been ruled out and patch testing revealed a strongly positive reaction for chromium and cobalt. The prosthesis has been removed and a fusion achieved using a cage filled with bone graft. She has been immediately and fully relieved from her pain. We report the radiological signs that enabled early diagnosis and treatment allowing favorable outcome.

Radial Neck Osteotomy for Malunion of Radial Neck Fracture in Childhood Sun, 09 Aug 2015 12:09:00 +0000 http://www.hindawi.com/journals/crior/2015/871429/ In a case of a neglected radial neck fracture in childhood, the management of initial fracture and its complications are subjected to discussion. In children, open reduction should be avoided but an angulation less than 30° must be obtained. Several techniques exist to manage symptomatic malunion in adults, including resection, prosthesis, and osteotomy. When performing an osteotomy, it is important first to preserve an intact osseous hinge to avoid avascular necrosis and second to align the edge of the radial head articular surface with the lateral edge of the coronoid process, in order to avoid overstuffing elbow joint.

Arthroscopic Microfracture Technique for Cartilage Damage to the Lateral Condyle of the Tibia Wed, 05 Aug 2015 17:15:51 +0000 http://www.hindawi.com/journals/crior/2015/795759/ This report describes the use of arthroscopic microfracture to treat a 10-year-old female patient with extensive damage to the cartilage of the lateral condyle of the tibia before epiphyseal closure, resulting in good cartilage recovery. Magnetic resonance imaging showed a defect in part of the load-bearing surface of the articular cartilage of the condyle articular of the tibia. The patient was diagnosed with damage to the lateral condyle cartilage of the tibia following meniscectomy, and arthroscopic surgery was performed. The cartilage defect measured approximately 20 × 20 mm, and microfracture was performed. Arthroscopy performed four months postoperatively showed that the cartilage defect was completely covered with fibrous cartilage, and the patient was allowed to resume sports activities. Four years postoperatively, she has had no recurrence of pain or hydrarthrosis.

Remote Hemorrhage in the Cerebellum and Temporal Lobe after Lumbar Spine Surgery Mon, 03 Aug 2015 14:32:29 +0000 http://www.hindawi.com/journals/crior/2015/972798/ Cerebellar hemorrhage remote from the site of surgery can complicate neurosurgical procedures. However, this complication after lumbar surgery is rare. Furthermore, hemorrhage in both the cerebellum and the temporal lobe after spine surgery is rarer still. Herein we present a case of remote hemorrhage in both the cerebellum and the temporal lobe after lumbar spine surgery. A 79-year-old woman with a Schwannoma at the L4 level presented with low back and bilateral leg pain refractory to conservative management. Surgery was undertaken to remove the Schwannoma and to perform posterior fusion. During the surgery, the dura mater was removed in order to excise the Schwannoma. Reconstruction of the dura mater was performed; postoperatively the patient had a cerebrospinal fluid leak. Five days after surgery, clouding of consciousness started gradually, and hemorrhage in the cerebellum and the temporal lobe was revealed by computed tomography. Emergent evacuation of the hemorrhage was performed and the patient recovered consciousness after the surgery. Leakage of cerebrospinal fluid may have induced this hemorrhage. While rare, intracranial hemorrhage after spine surgery can occur, sometimes requiring emergent intervention.

Nonsurgical Corrective Union of Osteoporotic Vertebral Fracture with Once-Weekly Teriparatide Thu, 30 Jul 2015 12:17:12 +0000 http://www.hindawi.com/journals/crior/2015/784360/ Osteoporotic vertebral fractures usually heal with kyphotic deformities with subsidence of the vertebral body when treated conservatively. Corrective vertebral union using only antiosteoporotic pharmacotherapy without surgical intervention has not been reported previously. An 81-year-old female with osteoporosis presented with symptomatic fresh L1 vertebral fracture with intravertebral cleft. Segmental vertebral kyphosis angle (VKA) at L1 was 20° at diagnosis. Once-weekly teriparatide administration, hospitalized rest, and application of a thoracolumbosacral orthosis alleviated symptoms within 2 months. Corrective union of the affected vertebra was obtained with these treatments. VKA at 2 months after injury was 8° (correction, 12°) and was maintained as of the latest follow-up at 7 months. Teriparatide has potent bone-forming effects and has thus been expected to enhance fracture healing. Based on the clinical experience of this case, teriparatide may have the potential to allow correction of unstable vertebral fractures without surgical intervention.

Surgical Correction of Posttraumatic Scapulothoracic Bursitis, Rhomboid Major Muscle Injury, Ipsilateral Glenohumeral Instability, and Headaches Resulting from Circus Acrobatic Maneuvers Sun, 26 Jul 2015 11:08:34 +0000 http://www.hindawi.com/journals/crior/2015/302850/ We report the case of a 28-year-old transgender (male-to-female) patient that had a partial tear of the rhomboid major tendon, scapulothoracic bursitis, and glenohumeral instability on the same side. These conditions resulted from traumatic events during circus acrobatic maneuvers. Additional aspects of this case that make it unique include (1) the main traumatic event occurred during a flagpole exercise, where the patient’s trunk was suspended horizontally while a vertical pole was grasped with both hands, (2) headaches were associated with the periscapular injury and they improved after scapulothoracic bursectomy and rhomboid tendon repair, (3) surgical correction was done during the same operation with an open anterior capsular-labral reconstruction, open scapulothoracic bursectomy without bone resection, and rhomboid tendon repair, (4) a postoperative complication of tearing of the serratus anterior and rhomboid muscle attachments with recurrent scapulothoracic pain occurred from patient noncompliance, and (5) the postoperative complication was surgically corrected and ultimately resulted in an excellent outcome at the one-year final follow-up.

Fracture of the Modular Neck in Total Hip Arthroplasty Wed, 22 Jul 2015 10:02:19 +0000 http://www.hindawi.com/journals/crior/2015/591509/ Modularity of the components in total hip arthroplasty has had an increase in popularity in the last decades. We present the case of a 53-year-old man with a history of avascular necrosis of the femoral head due to a hypophyseal adenoma. A total hip modular arthroplasty was implanted. Three and a half years after the surgery the patient attended the emergency room due to acute left hip pain with no prior traumatism. Radiological examination confirmed a fracture of the modular neck. A revision surgery was performed finding an important pseudotumoral well-organized periprosthetic tissue reaction. Through an extended trochanteric osteotomy the femoral component was removed, and a straight-stem revision prosthesis implanted. There are several potential advantages when using modularity in total hip arthroplasty that surgeons may benefit from, but complications have arisen and must be addressed. Various circumstances such as large femoral head with a long varus neck, corrosion, patient’s BMI, and activity level may participate in creating the necessary environment for fatigue failure of the implant.

Carpal Tunnel Syndrome Caused by Tumoral Calcinosis Tue, 21 Jul 2015 13:02:48 +0000 http://www.hindawi.com/journals/crior/2015/170873/ We present a case of carpal tunnel syndrome caused by systemic tumoral calcinosis. A 54-year-old woman experienced hand numbness that persisted for nine months. She had no family history or medical problem. A plain radiograph of her right wrist showed a calcified mass on the volar side of the wrist joint. The patient also experienced pain in her contralateral wrist joint and both right and left shoulders, which had calcification on radiography around the joint. Her condition was diagnosed as carpal tunnel syndrome caused by systemic tumoral calcinosis and a resection biopsy was performed. Histopathological analysis of the biopsied specimen showed basophile deposition inside the fibrous connective tissue. At 14 months after the treatment, she no longer had pain or numbness in her fingers and there was no recurrence of the mass. This patient’s condition is considered as a case of nonfamilial, systemic primary tumoral calcinosis. Since incomplete resection leads to a recurrence of the lesion, a follow-up radiography examination is needed to monitor symptom recurrence.

Postpartum Sacral Stress Fracture: An Atypical Case Report Sun, 12 Jul 2015 11:50:59 +0000 http://www.hindawi.com/journals/crior/2015/704393/ Sacral stress fractures are common in elderly people. However, sacral stress fracture should be always screened in the differential diagnoses of low back pain during the postpartum period. We present a case of sacral fracture in a thirty-six-year-old woman with low back pain and severe right buttock pain two days after cesarean section delivery of a 3.9 Kg baby. The diagnosis was confirmed by MRI and CT scan, while X-ray was unable to detect the fracture. Contribution of mechanical factors during the cesarean section is not a reasonable cause of sacral fracture. Pregnancy and lactation could be risk factors for sacral stress fracture even in atraumatic delivery such as cesarean section. Our patient had no risk factors for osteoporosis except for pregnancy and lactation. Transient or focal osteoporosis is challenging to assess and it cannot be ruled out even if serum test and mineral density are within the normal range.

Biologic Augmentation of the Ulnar Collateral Ligament in the Elbow of a Professional Baseball Pitcher Thu, 09 Jul 2015 06:06:45 +0000 http://www.hindawi.com/journals/crior/2015/130157/ Tears of the ulnar collateral ligament (UCL) of the elbow are common injuries in overhead athletes. Although surgical reconstruction of the UCL has improved outcomes, not all athletes return to their previous level of competition and when this goal is achieved, the time required averages one to two years. Therefore, additional techniques are needed to further improve return to play and the rate of return to play in overhead athletes. A construct comprising a dermal allograft, platelet rich plasma (PRP), and mesenchymal stem cells (MSCs) has been shown to successfully improve healing in the rotator cuff. Given the promising provisional findings, we postulated that this construct could also improve healing if applied to the UCL. Therefore, the purpose of the present report was to examine the feasibility of utilizing a dermal allograft, PRP, and MSC construct to augment UCL reconstruction in a professional baseball pitcher. No complications were encountered. Although limited to minimal follow-up, the patient has demonstrated excellent progress and has returned to activity. James K. Hoffman, Nicole M.

Two Cases of Contact Anterior Cruciate Ligament Rupture Combined with a Posterolateral Tibial Plateau Fracture Wed, 08 Jul 2015 11:02:14 +0000 http://www.hindawi.com/journals/crior/2015/250487/ Background. The combined occurrence of ACL rupture with a posterolateral tibial plateau fracture has not yet been reported. Two cases of such injuries have been treated in our department for the past three years. Findings. The two patients both suffered injuries from traffic accidents. The radiological examinations showed a ruptured ACL with fracture of the posterolateral tibial plateau. Reconstruction of the ACL was performed via a standard anatomical single bundle ACL reconstruction technique with autologous tendon by arthroscopy. A posterolateral tibia plateau approach was used to reduce and fix the fractured area with the aid of lag screws. After a one-year follow-up, the two patients recovered well and physical examinations showed full knee range of motion with no evidence of ACL instability. Conclusions. The cause of this type injury of ACL rupture with a posterolateral tibial plateau fracture was thought to be by a violent internal tibial rotation/anterior tibial translation without any valgus or varus knee force mechanism during the accident. Satisfactory clinical results were achieved with a standard anatomical single bundle ACL reconstruction by arthroscopy and ORIF for the posterolateral plateau fracture. Both patients reported excellent knee function and fracture healing. Liangjun Jiang, Haobo Wu, and Shigui Yan Copyright © 2015 Liangjun Jiang et al. All rights reserved. Neoprene Orthopaedic Supports: An Underrecognised Cause of Allergic Contact Dermatitis Tue, 07 Jul 2015 10:15:39 +0000 http://www.hindawi.com/journals/crior/2015/496790/ Thioureas, often contained within neoprene to provide water resistance, are an important cause of allergic contact dermatitis (ACD) in those who use neoprene products. We wish to present three cases of thiourea-induced ACD from three different orthopaedic supports containing neoprene. The first case was a 67-year-old woman who developed an itchy rash on her heel three weeks after using a neoprene insole for plantar fasciitis. The second case was a 47-year-old man who developed an itchy rash on his wrist after wearing neoprene wrist splints for psoriatic arthropathy. The third case was a 77-year-old woman who experienced a severe erythematous rash with blistering from a neoprene elbow brace she received following a humeral fracture. All patients were patch tested to the British Society of Cutaneous Allergy Standard and rubber series and a cut piece from all the relevant supports. At 96 hours, all patients had a + reaction to mixed dialkylthiourea, diethylthiourea, and the supports’ material. No other positive patch test reactions were identified. As neoprene is fast becoming one of the most popular materials used for orthopaedic supports, awareness of this reaction and close liaison between dermatologists and orthopaedic surgeons are therefore essential to allow for early recognition of this complication.

Recurrent Postoperative Spinal Epidural Hematoma in a Patient with Protein S Deficiency Tue, 07 Jul 2015 07:08:43 +0000 http://www.hindawi.com/journals/crior/2015/536592/ A 71-year-old man underwent cervical laminectomy and developed two symptomatic epidural hematomas during the acute postoperative period. On both occasions, drain obstruction was the predominant cause. Congenital Protein S deficiency was diagnosed postoperatively. Protein S is a vitamin K-dependent natural anticoagulant and is essential for inhibiting thrombosis in microcirculation. We assume that Protein S deficiency followed by perioperative bed-rest and surgical invasiveness led to severe hypercoagulability and subsequent drain obstruction. The present findings suggest that both bleeding disorders and hypercoagulability are risk factors for postoperative symptomatic epidural hematoma.

A Dual Biomechanical Failure: Exeter Stem and Pubic Rami Insufficiency Fracture, following Hybrid Total Hip Arthroplasty Mon, 06 Jul 2015 09:44:34 +0000 http://www.hindawi.com/journals/crior/2015/416102/ Introduction. Incidence of Exeter stem fracture is extremely uncommon. Pubic rami insufficiency fractures following arthroplasty are also rare. To our knowledge no cases of spontaneous stem failure with previous insufficiency fractures have yet been reported. Case Presentation. This report describes a case of spontaneous fracture through a cemented Exeter stem in a 66-year-old patient who had previously undergone a hybrid total hip replacement and was found to have bifocal pubic rami insufficiency fractures. The patient presented 18-year postprimary surgery with spontaneous fracture of the middle third of the cemented femoral stem and adjacent proximal femur. Conclusion. This report demonstrates a unique case of Exeter stem fracture with previous pelvic insufficiency fractures. The case adds to the rare occurrences of Exeter stem failure in the literature and highlights the risk of potential insufficiency fractures in patients undergoing total hip replacement.

Treatment of Bifocal Cyst Hydatid Involvement in Right Femur with Teicoplanin Added Bone Cement and Albendazole Mon, 06 Jul 2015 08:49:53 +0000 http://www.hindawi.com/journals/crior/2015/824824/ Although bone involvement associated with cyst hydatid is rarely seen, it can cause unintended results such as high recurrence rate, infection, sepsis, or amputation of relevant extremity. Because of this reason, its treatment is difficult and disputed. In the case of bifocal bone cyst hydatid in right femur, along with albendazole treatment, result of resecting cyst surgically and its treatment with teicoplanin with added bone cement is given. In conclusion, since the offered treatment method both supports bone in terms of mechanical aspect and also can prevent secondary infection, the method is thought to be a good and safe treatment approach.

Diabetic Muscle Infarction of the Tibialis Anterior and Extensor Hallucis Longus Muscles Mimicking the Malignant Soft-Tissue Tumor Sun, 05 Jul 2015 07:55:31 +0000 http://www.hindawi.com/journals/crior/2015/656307/ One of the most common causes of skeletal muscle infarction is diabetic muscle infarction (DMI), a rare complication associated with poorly controlled diabetes. We report an atypical case of DMI localized in the tibialis anterior (TA) and extensor hallucis longus (EHL) muscles of an elderly individual. A 64-year-old man with type 2 diabetes mellitus presented with a 6-month history of a palpable mass in his lower left leg. Magnetic resonance imaging (MRI) revealed that the mass exhibited heterogeneous signals on T1- and T2-weighted images and slight heterogeneous enhancement within the muscles on fat suppressed T1-weighted images. Because histopathological analysis revealed mostly necrotic muscle tissues but no neoplastic cells, we resected the affected muscles. A typical symptom of DMI is severe abrupt-onset pain in the region of the affected muscles, but the patient did not complain of pain. Therefore, the diagnosis and treatment for DMI were delayed, and widespread irreversible muscle necrosis developed. MRI findings of DMI can be similar to that of a malignant soft-tissue tumor. So, it is necessary to consider the malignant soft-tissue tumor as one of the differential diagnoses of DMI.

Chronic Exertional Compartment Syndrome in a High School Soccer Player Wed, 01 Jul 2015 10:12:51 +0000 http://www.hindawi.com/journals/crior/2015/965257/ Chronic exertional compartment syndrome (CECS) is a relatively rare condition that affects young adult athletes and often causes them to present to the emergency department. If left untreated, those who continue to compete at high levels may experience debilitating leg pain. Physicians may have difficulty differentiating CECS from other syndromes of the lower leg such as medial tibial stress syndrome, stress fractures, and popliteal artery entrapment. The gold standard for diagnosing CECS is intramuscular compartment pressure monitoring before and/or after 10 minutes of exercise. Some patients may choose to stop participation in sports in order to relieve their pain, which otherwise does not respond well to nonoperative treatments. In patients who wish to continue to participate in sports and live an active life, fasciotomy provides relief in 80% or more. The typical athlete can return to training in about 8 weeks. This is a case of a high school soccer player who stopped competing due to chronic exertional compartment syndrome. She had a fascial hernia, resting intramuscular pressure of 30 mmHg, and postexercise intramuscular pressure of 99 mmHg. Following fasciotomy she experienced considerable life improvement and is once again training and playing soccer without symptoms. James J. Bresnahan and William L.

Anterior Cruciate Ligament Reconstruction in Ehlers-Danlos Syndrome Sun, 28 Jun 2015 14:26:57 +0000 http://www.hindawi.com/journals/crior/2015/160381/ This report details the reconstruction of the anterior cruciate ligament in an 18-year-old man with Ehlers-Danlos syndrome (EDS). The reduced mechanical properties of the tissue in EDS can pose a challenge to the orthopaedic surgeon. In this case, we describe the use of a hamstring autograft combined with a Ligament Advanced Reinforcement System (LARS). There was a good radiographical, clinical, and functional outcome after two years. This technique gave a successful outcome in the reconstruction of the ACL in a patient with EDS and therefore may help surgeons faced with the same clinical scenario.
