目的：比较掌侧入路与背侧入路钢板内固定治疗桡骨远端骨折的临床疗效。方法回顾性分析2013年1～12月收治的96例桡骨远端不稳定性骨折患者的临床资料，按照手术入路分为 A组（54例）和B组（42例）。A组行掌侧入路钢板内固定术，B组行背侧入路钢板内固定术。随访1年，比较两组患者手术疗效指标及并发症发生情况。结果两组患者手术均成功，随访1年，骨折均愈合，均未见桡骨缩短，且关节面台阶均小于1 mm ，其中A组愈合时间（8．5±1．4）周，B组愈合时间（8．3±1．6）周，组间比较差异无统计学意义（t＝0．65，P＝0．52）。术后1年，A组腕关节功能优良率为88．9％，与B组88．1％的优良率比较差异无统计学意义（ P＞0．05），且掌倾角和尺偏角两组间比较差异无统计学意义（均 P＞0．05）。术后早期，A 组和B组并发症发生率分别为13．0％和11．9％，组间比较差异无统计学意义（ P＞0．05）。A组的术后远期并发症为3．7％，明显低于B组的19．0％，组间比较差异有统计学意义（P＜0．05）。结论掌侧入路与背侧入路钢板内固定术均为治疗桡骨远端不稳定性骨折的有效手术方式，手术成功率及术后腕关节功能优良率高，但背侧入路术后远期并发症发生率相对高，临床上应根据实际情况选择合适的手术入路。“,”Objective To compare the clinical effect of volar and dorsal plate internal fixation in the treatment of distal radius fracture .Methods The clinical data in 96 cases of unstable distal radius fracture meeting the inclusion criteria in our hospital from January 2013 to December 2013 were retrospectively analyzed .Those cases were divided into the group A (n=54) and B (n=42) according to the surgical approach .The group A was given the plate inter‐nal fixation by volar surgical approach ,while the group B was given the plate internal fixation by dorsal surgical ap‐proach .After the one‐year follow‐up ,the curative efficacy related indices and incidence of complications after surgery were compared between the two groups .Results All patients underwent successful operation .After the one‐year fol‐low‐up ,all fractures were healed with no radial shortening and less than 1 mm of all joint surface levels .The healing time was (8 .5 ± 1 .4) weeks in the group A and (8 .3 ± 1 .6) weeks in the group B ,the difference was not statistically significant(P>0 .05) .The excellent and good rate of wrist function at postoperative 1 year in the group A was 88 .9% ,which was statistically same with 88 .1% in the group B (P>0 .05) .And the inclination angle and ruler an‐gle had no statistically significant difference between the two groups (P>0 .05) .The incidence of short‐term compli‐cations in the group A and B was 13 .0% and 11 .9% respectively without statistical difference (P>0 .05) .However , the incidence of long‐term complications in the group A was 3 .7% ,which was statistically lower than 19 .0% in the group B (P<0 .05) .Conclusion Volar and dorsal plate internal fixation are both effective surgical approach for trea‐ting unstable distal radius fracture ,which have high success rate of operation ,excellent and good rate of wrist func‐tion ,but there is a relatively high incidence of long‐term complications in surgical approach of dorsal internal fixation . Clinically ,surgical approach should be selected appropriately according to patients′practical situation .
