可吸收钉棒内固定治疗累及关节面骨折

目的 探讨可吸收钉棒内固定治疗累及关节面骨折的效果。方法 1995年10月～2002年5月应用自身增强-聚乙酯(SR—PGA)、自身增强-聚丙酯(SR—PLLA)可吸收螺钉及固定棒手术治疗累及关节面的骨折32例。男25例，女7例。年龄20～65岁，平均33．3岁。均为外伤所致骨折，骨折关节面移位均超过2mm。术后行骨牵引或石膏外固定。结果 随访3个月～6年6个月(平均18．5个月)，骨折全部愈合，无移位、感染及局部积液．按照关节功能评定标准。优24例，良6例，可2例，优良率达93．7％。结论 可吸收内固定钉棒治疗累及关节面骨折，免除了患者二次手术取出内固定物的痛苦，是一种有效和较为理想的方法。

TREATMENT OF FRACTURE INVOLVED ARTICULAR SURFACE WITH ABSORBABLE SCREWS AND RODS

Objective To investigate the treatment results of fracture involved articular surface with absorbable screws and rods. Methods From October 1995 to May 2002, 32 patients with fracture involved articular surface were treated with absorbable screws and rods with the materials of SR-PGA and SR-PLLA. Bone traction or plaster external fixation were carried out postoperatively. Results The followed-up period varied from 3 months to 78 months, with an average of 18.5 months. According to the articular function evaluation criteria, the results were excellent in 24 patients, good in 6 patients and fair in 2 patients. The excellent and good rate was 93.7%. The fractures healed, without dislocation, infection and local effusion. Conclusion Internal fixation of absorbable screws and rods is a perfect procedure for treating fracture involved articular surface, which avoided the pain of taking out internal fixation materials of the second operation.
