Application of artificial humeral head prosthesis in the treatment of proximal humerus bone tumor / 中国综合临床

Objective To evaluate the clinical effects of the artificial humeral head prosthesis in the treatment of proximal humerus bone tumors. Methods Fifteen patients with proximal humerus bone tumor had excision of bone tumor and application of artificial humeral head prosthesis were analyzed retrospectively. Among them,8 patients had osteosarcoma,4 patients had giant cell tumor of bone,2 patients had chondrosarcoma, 1 patient had fibrosarcoma. Results All cases were followed up for average (39 ± 5 ) months after the surgery.The duration time of operation were( 110 ± 10) minutes in average. The bleeding volume during operation were (600 ± 41 ) ml in average. One patient with osteosarcoma died of recurrence and metastasis 20 months after the surgery. The functions of the other 14 patients were assessed by Enneking system and the average score was 23.3 ± 3.7. The overall rate of excellent or good results was 84.6% ( 11/15 ). Conclusion Limb salvage surgery with the artificial humeral head prosthesis is an efficacious treatment for proximal humerus bone tumors,which can improve short-term clinical outcome.
