Functional Reconstruction of Joint Following Resection of Malignant Bone Tumors around Shoulder Girdle:28 Cases Report

Objective To explore the classification,limb salvage strategy and treatmental results following resection of malignant bone tumors around the shoulder girdle.Methods 28 patients with malignant bone tumors of the shoulder girdle underwent a limb-sparing resection according to Malawer's surgical classification system of shoulder girdle.Various limb-salvage procedures were performed for all patients.They were evaluated with survival,recrudesce,and metastasis.The function outcome was assesssed with Enneking Function Evaluation System.Results 25 patients were followed-up with a mean time of 54 months (ranged 9～96 months).6 patients recrudesced,11 patients died.According to Enneking Function Evaluation System,the mean score of the upper extremity was 23 in reimplantation of tumor-bearing bone after alcohol devitalization group,24 in osteoarticular allograft group,24 in free periosteum vascularized clavicle group,26 point in endoprosthesis group,25 in the total scapulectomies and the head of humerus slinging group,28.5 in the partial scapulectomies group respectively.Conclusion The malignant bone tumors around the shoulder girdle can be resected completely.There were a variety of limb-salvage procedures following tumors resection,with which hand function can be preserved in the majority of patients with relieved pain and good function shoulder.
