- Abstract
In comparison with the lower extremity, there is relatively paucity literature reporting survival and clinical results of allograt reconstructions after excision of a bone tumor of the upper extremity. We analyze the survival of allograt reconstructions in the upper extremity and analyze the final functional score according to anatomical site and type of reconstruction. A consecutive series of 70 allograt reconstruction in the upper limb with a mean followup of 5 years was analyzed, 38 osteoarticular allograts, 24 allograt-prosthetic composites, and 8 intercalary allograts. Kaplan-Meier survival analysis of the allograts was performed, with implant revision for any cause and amputation used as the end points. he function evaluation was performed using MSTS functional score. Sixteen patients (23%) had revision surgery for 5 factures, 2 infections, 5 allograt resorptions, and 2 local recurrences. Allograt survival at five years was 79% and 69% at ten years. In the group of patients treated with an osteoarticular allograt the articular surface survival was 90% at five years and 54% at ten years. The limb salvage rate was 98% at five and 10 years. We conclude that articular deterioration and fracture were the most frequent mode of failure in proximal humeral osteoarticular reconstructions and allograt resorption in elbow reconstructions. The best functional score was observed in the intercalary humeral allograt.
