Abstract

We reviewed our experience as concerns 588 patients treated by resection for bone tumor and reconstructed by massive bank bone implant. The period taken into consideration goes from 1984 to 2001. The mean age of the patients was 24 years with a minimum of 1 and a maximum of 77 years: in 186 cases (31.6%) age was lower by 14 years. Most of the patients were referred for a diagnosis of malignancy (85%), and of these, 70% had undergone antiblastic therapy postoperatively according to the modalities of the protocols. Of the cases that were not treated by chemotherapy there are 16 that had a homoplastic graft after failure of a previous one. In a high number of cases (189) surgery included reconstruction of an intercalar segment of a long bone. Of these, 106 were in the femur, 69 in the tibia, and 14 in the humerus. One joint reconstruction was carried out in 128 cases of which 52 in the knee, 49 in the shoulder, 10 in the elbow, 11 in the wrist, 3 in the ankle, and 3 in the metatarsals. Fusion, which was one of the most frequent indications in the eighties, is used less today; overall it was carried out in 91 cases of which 65 in the knee, 14 in the hip, 9 in the ankle and 3 in the wrist. This type of implant may also be used in the pelves, and this took place in 56 cases using different procedures of reconstruction. The most current method of reconstruction for a joint is composite prosthesis, and this was used in 124 cases of which 67 around a knee, 53 in the hip, 4 in the shoulder. Finally, in 78 cases a vascularized fibula transplant was associated with an intercalar graft, fusion, or osteoarticular graft to increase the mechanical capacity of the implant together with a more rapid integration of the implant, particularly at the osteotomic lines. Despite the excellent results demonstrated in the first 3 years of follow-up, infection, resorption, delay in consolidation and fracture led to 18% failures of the implant. Massive homoplastic graft is still a good means of reconstruction that allows for excellent functional results, but despite this intense research activity is required to improve its mechanical hold in time together with better and complete integration.
