Abstract:ObjectiveTo compare the long-term effects of closed reduction and kirschner wire fixation under continuous traction and locking compression plate internal fixation in the treatment of unstable distal radius fractures.MethodsSixty patients with unstable distal radius fractures operated from August 2017 to January 2019 were selected,including 30 patients receiving closed reduction and kirschner wire internal fixation (kirschner group) and 30 patients undergoing volar locking plate internal fixation (plate group).Intraoperative bleeding,operation time,complications and wrist extension angle were observed and compared between two groups.Gartland-Werley wrist score was used to evaluate the function of the wrist joint.ResultsCompared with plate group,the operation time,intraoperative blood loss significantly decreased in Kirschner group（P<0.01）.All the patients were followed up for 6 to 12 months without death.In plate group,there was one case with radial artery ruptured and anastomosed during operation,and no abnormal blood supply was found during the follow-up.X-ray film showed that all patients achieved bony healing at the fracture ends,and no late infection occurred at the later stage.There were no statistical differences in Gartland-Werley score for wristpalmar flexion and dorsiflexion and wrist movement function between two groups (P>0.05).ConclusionsBoth closed reduction Kirschner wire fixation with continuous traction and locking plate internal fixation can achieve better clinical results in the treatment of unstable distal radius fractures.The former has more advantages in reducing the intraoperative bleeding and operation time.
