The diagnosis of OO of the hand can be difficult, and it should be considered with bony pain or bony swelling, especially when the history is a chronic one. The CT scan allows visualisation and precise localisation of such benign tumour of the hand. The care should be taken to make the excision complete in order to avoid recurrence.
Ewing's sarcoma of the finger is extremely rare. Pain and swelling of the affected finger are the most frequent presenting features. We report two cases of Ewing's sarcoma located at ring finger and the thumb in two children aged 14 and 10 years. The first patient died of generalised metastases despite surgery, chemotherapy and radiation therapy. The second had no localised recurrence or metastases after surgery and chemotherapy at last follow-up of 4.5 years after tumour resection. The tumour's surgical accessibility, chemotherapy, and radiation therapy improve the prognosis of this tumour.
Knee arthrodesis after tumor resection is a complex technique. Septic complications and mechanical failure are frequent regardless of the technique employed. They are related to the extent of bone sacrifice but also to that of soft tissues. The use of vascularised fibula alone and stabilisation by external fixation were the main shortcomings in this series. TYPE OF STUDY RETROSPECTIVE: Level IV.
