锁定加压钢板内固定治疗桡骨远端AO分型C型骨折的初期疗效观察

目的：探讨锁定加压钢板（LCP）内固定治疗桡骨远端 AO 分型 C 型骨折患者的临床效果。方法选取2011年7月至2012年12月收治的52例桡骨远端 AO 分型 C 型骨折患者作为观察对象，其中采用 LCP 内固定治疗27例（内固定组）、采用外固定支架治疗25例（外固定组）。通过术后随访，对比分析两组患者的临床治疗效果。结果两组患者术后3个月、6个月及末次随访时的掌倾角、尺偏角测定值差异无统计学意义（P >0.05）。内固定组患者术后6个月 Gartland-Werley 评分（4.12±1.41）分显著低于外固定组评分（5.06±1.57）分，差异有统计学意义（P <0.05），末次随访两组患者的 Gartland-Werley 评分差异无统计学意义（P >0.05）。内固定组患者术后末次随访的腕关节功能优良率（100%）高于外固定组优良率（92%），但差异无统计学意义（P >0.05）。结论 LCP 内固定治疗桡骨远端 AO 分型 C 型骨折与外固定支架效果相当，但其对早期腕关节功能恢复更有优势。

Early efficacy LCP internal fixation of distal radius AO type C fractures

Objective To explore the use of locking compression plate(LCP)AO clinical effect in patients with type C fractures in-ternal fixation of the distal radius. Methods Selected orthopedic hospital 52 cases of distal radius AO C patients with type fracture from July 2011 to December 2012 were treated as the observed object,which fixed 27 cases(internal fixation)of LCP implemented using external fixa-tion treatment of 25 cases(external fixation group),52 patients were followed up for clinical treatment effect difference compared two groups of patients. Results Two groups of patients with postoperative 3 months,6 months postoperatively,and at the last follow-up palm inclination Angle,feet there was no statistically significant difference measurements(P > 0. 05). Postoperative fixation group six months Gartland-Wer-ley score(4. 12 ± 1. 41)points were significantly lower than external fixation group(5. 06 ± 1. 57)points(P < 0. 05),the end of the follow-up of two groups of patients showed no Gartland-Werley score statistically significant(P > 0. 05). Postoperative follow-up at the end of a fixed group of excellent wrist function 100% higher than 92% of the external fixation group,but the difference was not statistically significant(P> 0. 05). Conclusion LCP internal fixation of distal radius AO type C fractures with external fixator quite effective,but it has the early ad-vantage wrist function recovery.
