目的：探讨临床手法复位经皮固定治疗尺桡骨远端骨折伴下尺桡关节分离的方法及疗效。方法：利用C臂X机透视，采用中医正骨手法复位，结合经皮克氏针固定及石膏外固定治疗尺桡骨远端骨折伴下尺桡关节分离[1]61例。结果：临床愈合时间4-8周，平均5周。随访3~12个月，骨折全部愈合，针孔感染3例，无畸形愈合，术后松动移位2例。按照临床功能评定标准，本组优54例，良7例，优良率为100％。结论：手法复位经皮固定治疗尺桡骨远端骨折伴下尺桡关节分离，创伤小，恢复快，并发症少，方法操作简单，适合临床开展运用。 Objective: To explore the method and curative effect of manual reduction and percutaneous fixation for distal ulnar and radial fractures with lower ulnar and radial joint separation.Methods:61 cases of distal ulnar and radial fractures with separation of lower ulnar and radial joints were treated with C-arm X-ray fluoroscopy, traditional Chinese medicine bone-setting reduction, percutaneous Kirschner wire fixation and plaster external fixation.Results: The clinical healing time was 4-8 weeks (average 5 weeks).Follow-up for 3~12 months showed that all fractures healed, pinhole infection was found in 3 cases, no malunion was found, and loosening and displacement were found in 2 cases.According to the standard of clinical function evaluation,54 cases were excellent and 7 good, the excellent and good rate was 100%.Conclusion: Manual reduction and percutaneous fixation for distal ulnar and radial fractures with separation of the lower ulnar and radial joints is a simple and suitable method for clinical application.
