Abstract
Following resection of primary malignant bone tumours of the humerus, limb salvage can be performed by vascularized fibula graft for reconstruction of large segmental defects.
In 12 patients with malignant bone tumour of the proximal humerus, tumour was resected and the bone defect reconstructed by vascularized fibula graft. Median age of the patients was 23 years. Median follow up was 114 months.
In 10 patients humeral head had to be resected and was replaced by fibular transplant including head and shaft of the ipsilateral fibula. Humeral head could be left in place in 2 patients. Median length of transplant was 17.2 cm. Radiographic union could be seen after 8 months in median. In 7 patients partial necrosis of the fibular head occurred, in 4 patients fracture of the transplant happened following trauma. In these 4 cases revision surgery was required. Partial necrosis of the head of fibula had no significant influence on shoulder function. One patient died of disease, the others are disease free. Enneking Index was 61% in median at time of last follow up. At donor side 3 cases of transient peroneal palsy could be seen.
We conclude that vascularized fibula graft is a successful surgical procedure for upper limb salvage especially for preservation of joint function also in long term follow up.
