闭合复位外固定架治疗伸直型桡骨远端骨折的疗效OA

Objective To investigate the efficacy of closed reduction and external fixation in the treatment of exten-sion-type distal radius fracture.Methods The 38 patients with extension-type distal radius fractures were treated with closed reduction and external fixation.The fracture healing time,occurrence of complications,radiographic indicators and Gartland-Werley score were recorded.Results All patients were followed up for3-7(4.17±1.06)months.All the fractures healed within 3-6 months.There were no postoperative complications such as pin tract infection or joint stiffness.Ulnar inclination and palmar tilt:At various postoperative time points,both were higher than the preoperation(P＜0.05).Radial styloid height:There was statistically significant difference between 1d after operation and the preoperation(P＜0.05),and there were no statistically significant differences at postoperative various time points(P＞0.05).Ulnar variance:All postoperative time points were superior to the preoperative(P＜0.05),there were statistically significant differences between postoperative 1 month,3 months and 1d after operation(P＜0.05),and there was no statistically significant difference between postoperative 3 months and 1 month after operation(P＞0.05).At the last follow-up,the Gartland-Werley scores were 72-100 points,with an excellent-good rate of 97.4%.Conclusions Closed reduction and external fixation provides satisfactory outcomes in the treatment of extension-type distal radius fracture,which can effectively restore the ulnar inclination,palmar tilt,radial styloid height,and ulnar va-riance.However,the attention should be paid to the risk of radial shortening leading to increased relative ulnar length and consequent positive ulnar variance.
