Case ReportsSynovial sarcoma with a large hematoma in the inguinal region.
We report the case of a patient with synovial sarcoma and a large hematoma of the inguinal region. The patient underwent tumor resection of the lower 2/3 of the acetabulum after preoperative chemotherapy. Twenty-four months after surgery, she is alive without any relapse and can walk without support.

Case ReportsOsseous lesions of the distal ulna: atypical location--unusual diagnosis. Report of three cases with similar imaging and different pathologic diagnoses.
Three cases with destructive bone lesions of the distal end of the ulna caused by different pathologic entities (Ewing's sarcoma, osteosarcoma, rheumatoid pseudotumoral synovitis) are presented, all with similar clinical and comparable x-ray and magnetic resonance imaging features. Although the distal end of the ulna may be resected without significant functional impairment, careful evaluation of treatment strategies compatible with oncologic standards is warranted.

Postoperative ambulatory level after hip fracture in the elderly predicts survival rate.
The purpose of this study was to evaluate whether the ambulatory level premorbid or at discharge reflected the survival rate better. Ambulatory level was retrospectively evaluated as a postoperative indicator of survival rate following operative treatment in 301 consecutive patients over 65 years old. ⋯ The postoperative ambulatory level at discharge reliably reflected the survival rate in the elderly after hip fracture, better than the premorbid ambulatory level. It is confirmed that the planning of the operation and rehabilitation to maintain the premorbid ambulatory level after hip fracture might be critical.

Scintigraphic evaluation of impaction grafting for total hip arthroplasty revision.
To determine the fate of an impacted allograft after a minimum follow-up of 1 year, we examined 9 of 40 patients who underwent revision arthroplasty with the impaction grafting technique. The allograft used in this study was morselized cancellous freeze-dried allograft. We examined these 9 patients with technetium-99 m methylene diphosphonate bone scintigraphy at an average of 14 (range 12-20) months after surgery. ⋯ Scintigraphic examination demonstrated that the area corresponding to the allograft had a remarkable radioactivity accumulation suggesting new bone formation. The allograft in total hip revision using the impaction grafting technique undergoes a significant neovascularization and new bone formation. This study suggests than when vigorous impaction is used, freeze-dried cancellous allograft can be used for impaction grafting.

Case ReportsStress fracture of the cuboid in an 8-year-old boy: a characteristic magnetic resonance imaging diagnosis.
A stress fracture of an 8-year-old boy diagnosed on magnetic resonance (MR) images is presented. Stress fractures of the cuboid are probably more common than previously reported. The diagnosis should be considered even when a history of trauma or chronic overload is absent. The MR appearance of the stress fracture was characteristic.
