可调节外固定支架结合有限内固定治疗C型桡骨远端骨折的临床观察

Clinical observation of adjustable external fixator combined with limited internal fixation for type C distal radius fractures

目的观察采用可调节外固定支架结合克氏针有限内固定治疗C型桡骨远端骨折的临床疗效。方法有完整随访资料桡骨远端骨折病人22例,根据AO/ASIF分型标准:C1型6例、C2型7、C3型9例,均采用可调节外固定支架结合克氏针有限内固定手术治疗。通过随访病人术后X线资料及检查腕关节功能恢复情况,评定疗效。结果随访6~18个月,平均13个月,X线片显示,所有骨折均在3个月内愈合,根据Garland-werley标准评定腕关节功能:优15例,良5例,可2例,优良率90.91%。结论采用可调节外固定支架结合克氏针有限内固定治疗C型桡骨远端骨折,能较好恢复并维持桡骨高度、掌倾角、尺偏角,可获得满意的腕关节功能。

Objective To-invesiigate the clinical efficacy of adjustable external fixaor combined with limited internal fixation for type C distal radius fractures.Methods A total of 22 patients with type C distal radius fractures were treated with adjustable external fixator combined with limited internal fixa-tion from October 2013 to January 2016.According to AO/ASIF classification,there were 6 cases defined as C1,7 cases as C2 and 9 cases as C3.All cases were followed up completely.The clinical efficacy was e-valuated based on the wrist join function and X-ray materials.Results They were followed up from 6 month to 18 month（mean 11 months）.It showed that all the fractures were healed within 3 months accord-ing to X-ray examination.According to Garland-werley evaluation standard,15 cases were excellent,5 cases were good and 2 cases were fair.The excellent and good rate was 90.91%.Conclusion For type C distal radius fractures,the method of adjustable external fixaor combined with limited internal fixation can recover and maintain radius height,volar tilt angle and ulnar inclination angle effectively.It can provide satisfactory wrist join function.
