C2 Solitary Bone Plasmacytoma Curettage and Vertebral Augmentation in an 83-Year-Old Female: Case Report and Review of Surgical Treatment Approaches in the Spine Sun, 17 Dec 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/5692402/ Surgically, solitary bone plasmacytoma (SBP) of the craniocervical junction (CCJ) is typically treated with cement augmentation and occipital-cervical stabilization (OCS). In the orthopedic spine literature, various surgical treatment options have been described for SBP, but only a few studies exist describing SBP of the CCJ with treatment involving cement augmentation alone. We report the case of an 83-year-old female found to have C2 SBP that was successfully treated with curettage and cement augmentation alone. Matthew J. Yousif, Taha A.

Sacral Osteoneogenesis after Complete Sacrectomy in a Patient with Ewing Sarcoma Sun, 17 Dec 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/7824687/ Ewing sarcomas are the second most common primary malignant bone tumors in childhood and adolescence which rapidly metastasize. Due to improvement of treatment options in recent years, the survival rate has significantly increased. Nevertheless, lethality is still high, and neurologic symptoms are frequent. To the best of our knowledge, this is the first reported case of a sacral osteoneogenesis after complete sacrectomy in a patient with Ewing sarcoma. T. Hockertz, W. Eberl, and M.

Medial Condyle Fracture (Kilfoyle Type III) of the Distal Humerus with Transient Fishtail Deformity after Surgery Thu, 14 Dec 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/9053949/ A “Fishtail deformity” is one of the well-known complications following pediatric lateral condyle or supracondylar fractures of the humerus. We herein report a case of medial condyle fracture (Kilfoyle type III) in an 11-year-old boy. He had a transient “fishtail deformity” of the trochlear groove after open reduction and internal fixation. As occurred in the current case, the bone remodeling and the improvement of ischemia of the trochlea after medial condyle fracture may be associated with the likelihood of recovery from transient “fishtail deformity.” Motoki Sonohata, Takema Nakashima, Hiroaki Suetsugi, Masaru Kitajima, Masaya Ueno, and Masaaki Mawatari Copyright © 2017 Motoki Sonohata et al.

Minimally Invasive Endoscopic Approach to the Cervicothoracic Junction for Vertebral Osteomyelitis Mon, 11 Dec 2017 04:27:23 +0000 http://www.hindawi.com/journals/crior/2017/2495041/ The selection of an anterior, lateral, or posterior approach to the cervicothoracic junction for surgical treatment of vertebral osteomyelitis is still a matter of debate. These ordinary approaches generally require an extensile exposure. This article describes a less invasive approach case of a vertebral osteomyelitis of T2/3 using a video-assisted operating technique of thoracic surgery (VATS). A 78-year-old female underwent anterior debridement and interbody fusion with bone graft at T2/3 using a lateral surgical approach through a right thoracotomy with VATS. The VATS through two small skin incisions in the axillary region provides a good view without requiring elevation of the scapula with extensile muscle dissection and rib resection. There was no complication without partial lobectomy due to pleural adhesion during the perioperative period. Currently, at 1 year after operation, the patient has no back pain with neurologically normal findings and no inflammation findings (CRP was 0.01 mg/dl). Although the operating field of the upper thoracic level in the lateral approach is generally deep and narrow, the VATS provides a good view and allows us to perform adequate debridement and bone fusion at the T2/3 level with a less invasive approach than those previously described anterior or laterally or posterior approach.

Candida albicans Osteomyelitis Pubis: The Possible Pathogenic Role of Pelvic Irradiation Sun, 03 Dec 2017 09:35:52 +0000 http://www.hindawi.com/journals/crior/2017/5961917/ Radiation to the pelvis, mainly directed against either prostatic or gynecologic cancers, is burdened by a lot of complications. The genitourinary tract is most frequently involved, presenting with bladder irritation, incontinence, and fertility disorders. However, side effects of radiation can also affect the bone, usually causing an osteolytic process which deteriorates the bone structure and leads to fractures, avascular necrosis, and other pathological insults. Here, we describe a case of Candida albicans osteomyelitis of the pubic symphysis as late complication of pelvic radiotherapy performed against prostate cancer.

Treatment of Atypical Ulnar Fractures Associated with Long-Term Bisphosphonate Therapy for Osteoporosis: Autogenous Bone Graft with Internal Fixation Wed, 29 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/8602573/ Long-term bisphosphonate use has been suggested to result in decreased bone remodelling and an increased risk of atypical fractures. Fractures of this nature commonly occur in the femur, and relatively few reports exist to show that they occur in other bones. Among eight previous reports of atypical ulnar fractures associated with bisphosphonate use, one report described nonunion in a patient who was treated with cast immobilization and another described ulna nonunion in one of three patients, all of whom were treated surgically with a locking plate. The remaining two surgical patients achieved bone union uneventfully following resection of the osteosclerotic lesion and iliac bone grafting before rigid fixation. We hypothesized that the discontinuation of bisphosphonate therapy, the use of teriparatide treatment, and low-intensity pulsed ultrasound (LIPUS) might have been associated with fracture healing.

Bone Bruise of the Thoracic Spine Caused by Mild Physical Activity in Children Tue, 28 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/8451797/ Vertebral bone bruise (VBB) in children commonly occurs following a fall from a height, and more than one vertebral body may be affected. We encountered 6 children each with a single VBB caused by mild physical activity. All the children had tenderness on the corresponding spinous process with no neurologic findings. Magnetic resonance imaging (MRI) showed typical findings of VBB in all cases. The children were treated conservatively with a soft thoracolumbar brace and instructed to rest with no physical activity for a month. At follow-up 1 month later, the back pain had diminished, and the signal changes seen on MRI had disappeared in all cases. We conclude that mild physical activity may be a cause of VBB in children and good clinical results can be achieved by using a soft thoracolumbar brace and rest.

Locked Central Fracture Dislocation of the Hip in a Child after Low-Energy Trauma Mon, 27 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/6873484/ We present the case of a 13-year-old boy who sustained a locked central fracture dislocation of the right acetabulum following a bicycle fall. Immediate external reduction maneuvers under general anesthesia were unsuccessful due to intrapelvic entrapment of the femoral head. Open reduction internal fixation was achieved 48 hours later. After an initial satisfactory postoperative course, the patient ended up developing severe hip osteoarthritis 16 months after the procedure. The rarity of this injury in children is discussed, with its possible implications on joint congruity and potential growth injury. Alexandre H. Nehme, Jack C. Daoud, Hicham G. Abdelnour, Jad N.

Arteriovenous Fistula after Anatomic All-Inside Anterior Cruciate Ligament Reconstruction Sun, 26 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/1034018/ We present the first case of an arteriovenous fistula after an all-inside anterior cruciate ligament (ACL) reconstruction. A seventeen-year-old boy had an uneventful ACL reconstruction. Four weeks after surgery, the patient was seen with a pulsating swelling at the lateral distal upper leg. Vascular consultation led to the diagnosis of pseudoaneurysm and arteriovenous fistula of the lateral superior genicular artery. Most likely, fistula is caused by the stab incision for preparation of the femoral tunnel, and no anatomical cause was found. The clinical presentation, previous cases of arteriovenous fistula after arthroscopic ACL reconstruction, possible causes, and management are discussed. Mathijs C. H. W.

Managing an Acute and Chronic Periprosthetic Infection Tue, 14 Nov 2017 06:38:00 +0000 http://www.hindawi.com/journals/crior/2017/6732318/ A case report of a 65-year-old female with a history of right total hip arthroplasty (THA) in 2007 and left THA in 2009 was presented. She consulted with our institution for the first time, on December 2013, for right hip pain and fistula on the THA incision. It was managed as a chronic infection, so a two-stage revision was performed. First-time intraoperative cultures were positive for Staphylococcus aureus (3/5) and Proteus mirabilis (2/5). Three weeks after the second half of the review, it evolved with acute fever and pain in relation to right hip. No antibiotics were used, arthrocentesis was performed, and a coagulase-negative staphylococci multisensible was isolated at the 5th day. Since the germ was different from the first revision, it was decided to perform a one-stage revision. One year after the first review, the patient has no local signs of infection and presents ESV and RPC in normal limits. The indication and management of periprosthetic infections are discussed.

Pseudomonas aeruginosa Septic Arthritis and Osteomyelitis after Closed Reduction and Percutaneous Pinning of a Supracondylar Humerus Fracture: A Case Report and Review of the Literature Tue, 14 Nov 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/8721835/ Infectious complications of closed reduction and percutaneous pinning of supracondylar humerus fractures are exceedingly rare. Although postoperative Pseudomonas infection is a feared complication associated with noncompliance and a wet cast, there are no reports in the literature of this occurring. We present the devastating complication of a pediatric patient who developed Pseudomonas aeruginosa subperiosteal abscess, osteomyelitis, and elbow septic arthritis after presenting to the clinic multiple times with a wet cast after closed reduction and percutaneous pinning of a supracondylar humerus fracture. We describe the treatment course for this patient, followed by the sequelae of posterolateral rotary instability. This case not only confirms that patients can get Pseudomonas infections if they get their cast wet but also stresses the importance of patient communication and compliance in preventing unfortunate complications.

A Unique Case of Melorheostosis Presenting with Two Radiologically Distinct Lesions in the Shoulder Mon, 06 Nov 2017 10:40:03 +0000 http://www.hindawi.com/journals/crior/2017/9307259/ Melorheostosis is a rare, nonhereditary, benign, mesenchymal condition of unknown aetiology affecting the bones and surrounding tissues. A male patient complaining of left shoulder pain, swelling, and mildly limited range of motion has an exclusive combination of the classic dripping wax lesion in the scapula and the myositis ossificans-like lesion in the deltoid muscle; this combination is the first to be reported in the shoulder. Both lesions showed typical findings of melorheostosis in radiographs, CT, MRI, and bone scan. This case has a stationary course over the follow-up period, and no specific treatment is needed in due course. Ahmed A. Elsheikh, Rohan S. Pinto, Alpesh Mistry, and Simon P.

Bone Resection for Isolated Ulnar Head Fracture Thu, 26 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/3519146/ Distal ulnar fractures often occur with distal radius fractures (DRFs), and ulnar styloid fractures commonly occur in the setting of DRF. However, isolated ulnar head fractures are rare. We report a case of isolated ulnar head fracture in which we performed bone resection because the ulnar head bone fragment fractured when internal screw fixation was attempted. His outcome at 18 months postoperatively was considered excellent. However, we do not advocate bone resection other than failure of fixation and the difficult case to perform internal fixation. Longer follow-up would be needed because bone resection might lead to osteoarthritis of the distal radioulnar joint in the future.

Therapeutic Management of a Substantial Pelvic Aneurysmatic Bone Cyst Including the Off-Label Use of Denosumab in a 35-Year-Old Female Patient Tue, 17 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/9125493/ Aneurysmal bone cysts (ABC) are benign bone tumors, which are highly vascularized. The main course of treatment is curettage followed by bone grafting or cement insertion. Still recurrence remains a main problem for patients. Denosumab is a monoclonal antibody, which acts as an inhibitor of the RANK/RANKL pathway, diminishing bone turnover. Recent case reports have shown that Denosumab can be a promising therapeutic agent for people suffering from therapy-resistant ABC. We report the case of a 35-year-old female patient presenting with a pronounced ABC of the pelvis. Since the tumor was inoperable, Denosumab was administered, leading to a significant shrinkage of the lesion, which allowed surgical intervention. Upon recurrence, Denosumab was restarted putting the patient once more into remission. Follow-up was four years overall with a clinical and radiological stable disease for fifteen months after final discontinuation of the monoclonal antibody. Therefore, our case further underlines the potential of Denosumab in the treatment of ABC. D. Ntalos, M. Priemel, C. Schlickewei, D. M. Thiesen, J. M. Rueger, and A. S. Spiro Copyright © 2017 D.

Hyperphosphatemic Tumoral Calcinosis after Total Knee Arthroplasty Mon, 16 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/1528201/ We report a case of hyperphosphatemic tumoral calcinosis (TC) that occurred after total knee arthroplasty. A 64-year-old Japanese man presented with painful swellings in both shoulders, the left elbow, and the right hip that developed after he underwent total knee arthroplasty (TKA). The pathology of the patient’s bone at the time of TKA included a thick osteoid seam with calcareous deposition at the margin of the trabecular bone, which is not generally seen in osteoarthritis. Computed tomography scans of the swollen joints demonstrated leaflet and amorphous calcification masses around the joints. We diagnosed the patient with TC. The present case highlights that TC lesions are rare but should be considered in the differential diagnosis of subcutaneous soft and hard masses around the joint.

Lumbar Spondylodiscitis Caused by Burkholderia cepacia in a Previously Healthy Patient Sun, 15 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/1396950/ Burkholderia cepacia spondylodiscitis is a rare entity that has been reported in only four cases. We hereby report the case of a 43-year-old, previously healthy, woman who was found to have a B. cepacia spondylodiscitis after a cholecystectomy. She was treated with a three-month regimen of ceftazidime and ciprofloxacin with complete clinical, biological, and radiological remission.

Delayed Tibial Osteomyelitis after Anterior Cruciate Ligament Reconstruction with Hamstrings Autograft and Bioabsorbable Interference Screw: A Case Report and Review of the Literature Sun, 15 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/6383526/ Osteomyelitis following arthroscopically assisted anterior cruciate ligament (ACL) reconstruction has rarely been reported in the literature. We report a case of a 20-year-old female who had delayed tibial osteomyelitis and a pretibial cyst with culture-positive, oxacillin sensitive Staphylococcus epidermidis 15 months after an ACL reconstruction with hamstring autograft. Soft tissue fixation within the tibial tunnel was with a poly-L-D-lactic acid (PLDLA) bioabsorbable interference screw. The patient underwent surgical treatment with curettage, debridement, hardware removal, and bone grafting of the tibial tunnel followed by a course of intravenous antibiotics. Arthroscopic evaluation demonstrated an intact ACL graft without any evidence of intra-articular infection. The patient returned to collegiate athletics without any complications. While the most common biologic complications include pretibial cysts, granuloma formation, tunnel widening, and inflammatory reactions, infection is exceedingly rare. Late infection and osteomyelitis are also rare but can occur and should be considered in the differential diagnosis. Kevin S. Weiss, Justin M. Weatherall, Jen Eick, and James R.

Spontaneous Bilateral Sternoclavicular Joint Septic Arthritis and Lumbar Discitis: An Unusual Case in a Healthy Adult Mon, 09 Oct 2017 07:17:33 +0000 http://www.hindawi.com/journals/crior/2017/7101694/ Introduction. Septic arthritis of the sternoclavicular (SC) joint is a rare condition. Typically, it presents in patients with risk of infection and is usually unilateral. In this report, we describe a case of spontaneous bilateral sternoclavicular joint infection of an otherwise healthy adult. Case Presentation. A 67-year-old man presented in our hospital complaining of 2-week history of neck and chest pain which was radiating to his shoulders bilaterally. Clinical examination revealed erythema and swelling of the sternoclavicular area. Inflammatory markers were raised. Image investigation with CT and MRI was undertaken and verified the presence of bilateral sternoclavicular joint infection. The patient received prolonged course of intravenous antibiotics since his admission. The patient was discharged in a good condition and followed up in clinic. Conclusion. High index of clinical suspicion of SC joint infection is important for early diagnosis to avoid further complications.

Successful Pelvic Resection for Acetabular Hydatidosis Mon, 09 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/9495783/ Background. Hydatidosis of the bone is a rare occurrence (0.9 to 2.5% of all localization of the disease). In those occurrences, the pelvic bone is the second most frequent localization. Curative treatment of pelvic bone hydatidosis is difficult and a consensus is yet to be found. Clinical Case. We report a case of hydatidosis of the ischium, extended to the homolateral hip. The patient was treated through hip resection using patient-specific cutting guides, followed by total hip reconstruction. Albendazole was administered to the patient for two months before the surgery and for three months following the surgery. Conclusions. In a young patient, hydatidosis of the pelvic bone can be treated with satisfying results through wide resection of the hip coupled with an antiparasitic treatment administered before and after the surgery. Prosthetic reconstruction, similar to what is done in cancer surgery, restores good functions.

Radiofrequency-Targeted Vertebral Augmentation: Case Report of a Patient with 7 Osteoporotic Vertebral Fractures in a Variant of Osteogenesis Imperfecta Wed, 04 Oct 2017 07:10:06 +0000 http://www.hindawi.com/journals/crior/2017/7191476/ Introduction. Radiofrequency-targeted vertebral augmentation (RF-TVA) is a recognized treatment for painful compression fractures. RF-TVA in a patient with multiple compression fractures due to type I osteogenesis imperfecta (OI) has not been previously reported. Case Presentation. A 54-year-old patient with type I OI is presented with a segmental thoracic hyperkyphosis and 7 recent vertebral compression fractures. Because of persistent severe thoracolumbar back pain despite conservative therapy, RF-TVA was indicated. Nocturnal back pain was almost completely relieved at all postoperative time points evaluated. However, overall pain relief dropped only slightly from 7 to 5 on the numerical rating scale (NRS) at the 6-week follow-up, and there was only a small decrease in the Oswestry Disability Index (ODI) from 72% to 63%. An MRI at the 3-month follow-up revealed hyperintensity at levels T11 and T12, indicating slight recollapsing. At the 6-month follow-up, the ODI improved to 55%, although overall pain had worsened to 6 on the NRS. Pain at rest remained at a very low level. Conclusion. Despite the remaining lumbago, RF-TVA may be a good option for patients with OI who have multiple fractures. However, fractures at multiple levels and segmental thoracic hyperkyphosis may increase the risk for recollapsing and ongoing pain.

Usefulness of Sacral Sublaminar Wire for Low Transverse Sacral Fractures: Two Cases’ Report Wed, 04 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/7396564/ Low transverse sacral fractures are rare, with only two published reports regarding their surgery. The complication associated with surgery for sacral fractures is the prominence of implants. In addition, screw fixation below S3 is impractical. We performed posterior sacral fixation using S2 alar iliac (S2AI) screws and sacral sublaminar wires for low transverse sacral fractures. Case 1 was 65-year-old male with an S2-3 transverse sacral fracture. We performed laminectomy (S2-3) and passed ultrahigh molecular weight polyethylene (UHMWPE) cables from laminectomy area to the third posterior sacral foramina. We inserted S2AI screws and connected rods. We also tightened the UHMWPE cables. The implants did not protrude into skin. One year after surgery, the sacral fracture healed without any displacement. Case 2 was a 42-year-old female with an S2 transverse sacral fracture. We performed laminectomy (S1–3) and passed UHMWPE cables from laminectomy area to the third and fourth posterior sacral foramina. We inserted S1 pedicular screws and S2AI screws and connected rods. We also tightened UHMWPE cables. The implants did not protrude into skin. One year after surgery, the sacral fracture healed without any displacement. We consider sacral sublaminar wires to be useful bone anchors in lower sacrum. Tatsuro Sasaji, Hideki Imaizumi, and Taishi Murakami Copyright © 2017 Tatsuro Sasaji et al. All rights reserved. Natural Remission of Major Periprosthetic Osteolysis following Total Hip Arthroplasty with Metal-on-Metal Bearings Wed, 04 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/2576196/ The natural course of adverse events following the use of metal-on-metal (MoM) bearings in total hip arthroplasty (THA) is not well known. In this article, we report the case of a patient with asymptomatic major acetabular osteolysis following MoM THA that diminished gradually without any surgical intervention. A 58-year-old male underwent one-stage bilateral MoM THA for bilateral osteoarthritis. Four years after THA, major acetabular osteolysis developed in his right hip without any local or systemic symptoms. The patient underwent a careful radiographic and clinical observation without any surgical intervention because he did not want to undergo revision surgery. The lesion gradually diminished after 7 years, and most of the osteolytic area was replaced by newly formed bone at 10 years. He continues to be followed with no evidence of cup loosening or migration. Our observation suggests that a periprosthetic osteolytic change related to the use of MoM bearings has the potential for natural remission.

Sacral Stress Fracture in an Amateur Badminton Player Tue, 03 Oct 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/4268981/ Sacral stress fractures are rare among athletes but have been reported most frequently in long distance runners. We report herein the first case of a sacral stress fracture in an amateur badminton player. A 16-year-old, left-handed adolescent girl, who had just started to play badminton 3 months previously, complained of acute left buttock pain when she received a shuttlecock. Magnetic resonance imaging revealed a linear lesion of the left sacrum with low signal intensity on T1- and high signal intensity on T2-weighted images, which was consistent with a stress fracture. Conservative treatment with rest relieved her symptoms. Her fracture was considered to have occurred due to repetition of an exercise that caused excessive vertical power.

Compression of the Femoral Vessels by a Pseudotumor after Metal-on-Metal Total Hip Arthroplasty Sun, 01 Oct 2017 07:22:45 +0000 http://www.hindawi.com/journals/crior/2017/2594902/ Here we present a case of pseudotumor following total hip arthroplasty (THA) that resulted in a circulatory disturbance caused by compression of the femoral vasculature. A 63-year-old man presented with pain, swelling, and redness of the left leg 5 years after primary metal-on-metal THA using the AML-Plus stem, Pinnacle® acetabular cup, and 36 mm diameter Ultamet™ metal head system (DePuy Orthopaedics, Warsaw, IN). Enhanced computed tomography and magnetic resonance imaging revealed a large cystic lesion extending from the left hip anteriorly to the intrapelvic region and compressing the left femoral vessels. Percutaneous puncture of the lesion yielded a dark red aspirate and the patient was diagnosed to have a pseudotumor causing compression of the femoral vessels. We performed revision surgery to replace the metal head and metal liner with a smaller ceramic head and polyethylene liner without removal of the stem. Corrosion of the head-neck junction was identified intraoperatively with no obvious wear on the bearing surfaces. The left leg swelling and redness improved immediately postoperatively. A large pseudotumor should be kept in mind as a cause of vascular compression with unilateral leg edema in a patient who has undergone metal-on-metal THA.

Quadriceps Tendon Rupture in an Adolescent Athlete Tue, 26 Sep 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/2718013/ Quadriceps tendon rupture is an uncommon injury that usually occurs in middle-aged and elderly men with a history of chronic illnesses. We report the case of a 17-year-old healthy adolescent male baseball player who sustained this injury as a result of sudden deceleration in his left knee. He initially reported to the emergency department and then presented to our practice, where he was diagnosed with a quadriceps tendon tear. Preoperatively, he was unable to perform a single straight-leg raise. During surgical repair, the free edge of the quadriceps tendon was mobilized and anchored into the superior pole of the patella, followed by sutures to ensure reinforcement of the quadriceps footprint. His postoperative course progressed normally, demonstrating full range of motion at 3 months and return to team training at 5 months. Unlike previously reported quadriceps tendon ruptures in adolescents, to our knowledge, this is the first report of a patient who sustained such an injury without previous trauma to his knee or quadriceps mechanism. It is possible that weakened tendon integrity from repeated microtrauma during training combined with the sudden weight change distribution may have resulted in the injury. As urgent surgical intervention is necessary to ensure efficient recovery and return to sport, the sports medicine practitioner must remain educated and vigilant on caring for these patients.

Complete Resection of a Massive Synovial Osteochondromatosis of the Hip Using an Anterior Approach: A Report of Two Cases Wed, 20 Sep 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/9806863/ Arthroscopic excision of synovial osteochondromatosis of the hip is commonly performed. However, when the lesion extends to the extra-articular space of the hip joint, excision using arthroscopy becomes difficult. Although surgical dislocation of the hip with a trochanteric flip osteotomy is commonly used, manual access to the inferomedial portion of the acetabulum remains difficult. In this case report, we describe arthroscopic resection followed by open surgery using an anterior approach with or without surgical dislocation to excise a synovial osteochondromatosis of the hip that had extended to the extra-articular space and formed a herniation sac. Excision was completed without complications. An anterior approach with or without surgical dislocation should be considered as a surgical option for the treatment of a massive synovial osteochondromatosis of the hip joint.

Triplane Fracture of the Proximal Tibia: A Case Report and Literature Review Mon, 18 Sep 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/6490728/ Background. The triplane fracture, a unique transitional physeal injury, is classically described in the distal tibia. A small number of additional anatomic locations are documented in the orthopaedic literature. Methods. Available literature surrounding triplane fractures was reviewed. We describe a rare case of a proximal tibial triplane fracture in a thirteen-year-old girl, suffered during a skiing accident. Results. Using arthroscopically assisted percutaneous reduction techniques an anatomic reduction was achieved. Conclusion. We outline the surgical and postoperative techniques for management of this unique injury. Jason Strelzow, Alexander Aarvold, and Christopher W. Reilly Copyright © 2017 Jason Strelzow et al.

A Case of C5 Vertebral Chordoma in a 73-Year-Old Patient with More Than 8 Years of Follow-Up after Total Piecemeal Spondylectomy Tue, 12 Sep 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/3284131/ Chordoma arising from the cervical spine is rare and the traditional long-term prognosis is typically poor. Total en bloc spondylectomy with a wide margin is generally accepted to be the most appropriate management for thoracic and lumbar malignant tumors. However, this method is still challenging for the cervical spine because of the proximity of the tumor to the vertebral arteries and neural elements. Here, we report a 73-year-old man with a C5 vertebral chordoma treated with total piecemeal spondylectomy. Histological examination revealed pathognomonic physaliphorous cells with mucus-filled cytoplasm in the tumor, and the ratio of Ki-67-positive cells within the tumor was high (19.0%), showing active proliferation rate. Local recurrences were found at 9 months, 4 years and 2 months, and 6 years after the initial surgery. All the recurrences were encapsulated and isolated and treated with an additional en bloc resection successfully at each stage. Eight years after the initial total piecemeal spondylectomy, the patient maintained his intact neurological status without local recurrence or metastasis. The prognosis of cervical chordoma depends on the patient’s age, surgical procedures, and histological features. In this report, we present that piecemeal spondylectomy is an alternative management for aged patients with cervical chordoma, even for those with high MIB-1 index.

Successful Treatment of a 15-Year-Old Nonunion of a Midshaft Clavicle Fracture Causing Brachial Plexus Compression Sun, 10 Sep 2017 00:00:00 +0000 http://www.hindawi.com/journals/crior/2017/5105670/ A 49-year-old man with a 15-year-old nonunion of a midshaft clavicle fracture suffered from progressive tingling in his entire arm and fingers for two years, due to irritation of the brachial plexus in the costoclavicular space, especially upon elevation of the arm. After open reduction and internal plate fixation, all symptoms were resolved and complete consolidation of the fracture was achieved at one-year follow-up. This case demonstrates two things: brachial plexus compression can occur even many years after a nonunion of a clavicle fracture and union can be still achieved, even in a longstanding nonunion.
