Proximal Humerus Tumor Resection and Reconstruction Using Osteoarticular Allograft

BackhroundsProximal humerus is one of the most common sites of tumor, and a principal therapeuticapproach in patients with tumor in the extremities is limb salvage and osteoarticularallograft reconstruction. This study was designed for evaluation of tumor resection andreconstruction of proximal humerus using osteoarticular allograftMethods18 patients with proximal humerus bone tumors were included in this study. In allcases, tumor site was resected and then reconstructed using osteoarticular allograft.The outcomes including allograft survival, complication, and the functional ratingsystem of the Musculoskeletal Tumor Society (MSTS) were evaluatedResultsIn patients with a mean age of 14.56 ± 27.26 years after 3.6 years of follow-up, %11reported infections, %16 recurrence, %11 allograft fraction, and %22 nonunion. Therewas no significant difference between MSTS scores and tumor types (p = 0.584). A patient withEwing›s sarcoma died during three years of follow-upConclusionsThe purpose of orthopedic surgery is to restore function while resection is performedfor malignancy. Given that proximal humerus allograft has an optimal effect in termsof short-term complications, patients may need to undergo revision surgery in thelong run. Therefore, studies with a larger sample size and prolonged follow-up arerecommended
