[Limb-preserving segmental bone resection for malignant bone tumors of the extremities: a report of 27 cases]

Abstract

Segmental bone resection with preservation of the affected limb was performed in 27 patients with malignant bone tumors. Diagnosis as confirmed by histopathology was: osteosarcoma (n = 8), chondrosarcoma (n = 3), fibrosarcoma (n = 2), malignant fibrous histiocytoma (n = 2), giant cell tumor (n = 6), reticulum cell sarcoma (n = 1), myeloma (n = 1) and metastatic bone tumor (n = 4). Four different kinds of operative procedure were used: enbloc resection of shoulder girdle in 13 cases, segmental resection and replantation of distal forearm in 1, partial hemipelvisection in 6 and segmental resection of the lower thigh with leg rotation plasty in 7. Twenty four patients were followed up from 16 months to more then 12 years. Twenty patients survived for more than 2 years, 9 patients survived over 5 years with functional limbs. The 2- and 5-year survival rate was 83.3% and 37.5%, respectively.
