Twenty-five patients underwent scapulectomy for various tumours between 1989 and 2005. We describe 23 patients with scapular tumours who were followed-up for a minimum of 2 years after scapulectomy. The average age was 29 years, and two-thirds of the patients were male. Nineteen patients had malignant neoplasms, of which chondrosarcoma was most common, followed by Ewing's sarcoma. Surgical staging was by Enneking's system, with stage IIB being the most frequent. Fifteen patients underwent total scapulectomy, and the rest had their glenoid retained. With an average follow-up period of 66.7 months (23-202 months), functional and oncological outcomes were evaluated for all patients. Two patients had superficial wound infections requiring antibiotics, and one had skin necrosis requiring skin cover. [831][832][833][834][835][836]

Metastatic tumours are the most common type of tumours in the spine of which only 10% occur in the cervical spine. We report a rare presentation of metastatic pheochromocytoma of the cervical spine which was successfully treated operatively. Adequate precautions should be taken during surgery as the tumour is very vascular. Radiotherapy is useful in the treatment of residual tumour.

Our objective was to assess and validate low-dose computed tomography (CT) scanogram as a post-operative imaging modality to measure the mechanical axis after navigated total knee replacement. A prospective study was performed to compare intra-operative and post-operative mechanical axis after navigated total knee replacements. All consecutive patients who underwent navigated total knee replacement between May and December 2006 were included. The intra-operative final axis was recorded, and postoperatively a CT scanogram of lower limbs was performed. The mechanical axis was measured and compared against the intra-operative measurement. There were 15 patients ranging in age from 57 to 80 (average 70) years. The average final intra-operative axis was 0.56°varus (4°varus to 1.5°valgus) and post-operative CT scanogram axis was 0.52°varus (3.1°v arus to 1.8°valgus). The average deviation from final axes to CT scanogram axes was 0.12°valgus with a correlation coefficient of 0.9. Our study suggests that CT scanogram is an imaging modality with reasonable accuracy for measuring mechanical axis despite significantly low radiation. It also confirms a high level of correlation between intra-operative and post-operative mechanical axis after navigated total knee replacement.

Limb salvage surgery with chemotherapy is a viable treatment option for patients with malignant fibrous histiocytoma of bone. It achieves higher survival rates than resection alone. Such therapy improves quality of life and provides a useful and functional limb.
