定制人工肱骨头置换治疗15例肱骨近端骨肿瘤的临床研究

A clinical research of custom-made humeral head prosthesis replacement treatment for 15 cases of proximal humerus tumor

目的评价定制人工肱骨头置换治疗肱骨近端骨肿瘤的疗效。方法对该院2002年1月至2009年1月收治的15例肱骨近端骨肿瘤患者行瘤段切除及定制人工肱骨头置换治疗,并进行术后康复训练。术后6个月采用肌肉骨骼肿瘤学会93(MSTS93)评分进行功能评价。结果随访12～45个月,无感染、假体松动、假体脱位、假体周围骨折等并发症。患者MSTS93评分平均为(20.60±3.35)分,肢体功能优5例,良8例,中2例,优良率为86.67%。结论定制人工肱骨头置换是治疗肱骨近端骨肿瘤的有效方法,术后肩关节功能恢复好。

Objective To evaluate curative effect of custom-made humeral head prosthesis replacement treatment for proximal humerus tumor.Methods 15 patients with proximal humerus tumor from January 2002 to January 2009 in the hospital were subjected to tumor resection and custom-made humeral head prosthesis replacement,followed by postoperative rehabilitation training.Musculoskeletal tumor society93（MSTS93） scale system was employed for functional assessment 6 month after surgery.Results No complication of infection,prosthesis loosening,prosthesis dislocation,periprosthetic fracture occurred during 12-45 months follow-up.The average MSTS93 score was 20.60±3.35.Limb function evaluation showed excellent in 5 cases,good in 8 cases,fair in 2 cases,and the rate of excellent and good was 86.67%.Conclusion Custom-made humeral head prosthesis replacement is an effective method to treat proximal humerus tumor with good postoperative recovery of shoulder joint function.
