RESUMEN
In revision hip surgery, allografts are useful for restoring the bone stock and allow the muscle fixation avoiding the use of massive metallic prothesis. MATERIAL AND METHODS: We have reviewed 51 hip reconstructions with a follow up of 4 years and half (1982 - 1991). Indications were: - revision arthroplasties with destroyed acetabulum, - bone tumors (mainly chondrosarcoma). RESULTS: The results are good for pain, articular movement and the consolidation of the allograft host bone junction. Some complications were encountered: - Post-operative death (early or late for tumoral extension) in case of major surgery for tumor (4 cases). - Deep infections (2 cases). - Weakness of the gluteus medius with hip dislocation needing anti-dislocation device. - Aseptic serous fluid leak meaning immunobiologic reaction of bone grafts (3 cases). DISCUSSION: This surgery has to be compared to massive reconstruction prostheses, arthrodesis with limb shortening, femoral head and neck resection and in some cases inter ilio-abdominal amputation which gives also major post-operative complication.
