Surgical Technique and Outcome of Custom Joint-Sparing Endoprosthesis as a Reconstructive Modality in Juxta-Articular Bone Sarcoma

Figure 4

(a) MRI of right tibia of patient with a tibial osteosarcoma, with 4.5 cm remaining length for anchorage of JSE after resection of the tumor with negative margin. (b) Left proximal femur X-ray of a failed bone allograft and DHS cut-off, with 1 cm of cortical bone remaining below the lesser trochanter. A JSE can be used here to revise this failed bone allograft. (c) Left humerus X-ray of postchemotherapy humerus osteosarcoma, showing a 3 cm of cortical bone remaining above the olecranon fossa which makes the sparing of the elbow joint possible. Furthermore, 2.5 cm of bone is remaining proximally making the sparing of the glenohumeral joint possible.
