Proximal ulna endoprosthetic replacement for bone tumours in young patients.

Purpose: The optimal reconstructive method after resection of malignant bone tumours of the proximal ulna is unknown.We report the outcome of endoprosthetic replacement in a young patient population.

Methods: This was a retrospective review of four patients[three males and one female; mean age 17.

Atypical pseudotumour after metal-on-polyethylene total hip arthroplasty causing deep venous thrombosis.

We describe a patient who developed a mass extending into the pelvis, five years after a metal-on-polyethylene total hip arthroplasty (THA). The histological pattern of perivascular lymphocytic infiltrate and fibrinoid necrosis was more in keeping with a metal-on-metal bearing failure. The pseudotumour compressed the femoral vein causing a deep venous thrombosis.

Neuritis ossificans of the common peroneal nerve: a case report.

Neuritis ossificans is an extremely rare reactive process affecting peripheral nerves, which can be challenging to diagnose and treat. Magnetic resonance imaging (MRI) is an excellent imaging modality for these lesions, showing inflammatory reaction around the nerve. Only a few cases have been previously reported, and all of the patients underwent surgical resection.

Proximal femoral replacements for metastatic bone disease: financial implications for sarcoma units.

Metastatic pathological fractures of the proximal femur are increasingly treated by endoprosthetic proximal femoral replacement. We report the results and the costs incurred performing these procedures at our supra-regional sarcoma unit. Sixty-two patients underwent 63 proximal femoral replacements for metastatic bone disease over a seven-year period.
