目的 探讨掌侧入路角度锁定接骨板治疗不稳定型桡骨远端骨折的临床效果.方法 选取我院收治的170例不稳定型桡骨远端骨折患者为研究对象,按其治疗方法分为观察组和对照组,每组85例.观察组行掌侧入路角度锁定接骨板治疗,对照组行闭合复位、外固定支架治疗.观察两组患者的临床治疗效果与骨折愈合情况,应用Gartland-Werley系统评分对两组患者的腕关节功能恢复情况进行评价,并比较治疗前后影像学测量指标的差值.结果 患者经掌侧入路角度锁定接骨板治疗后的优良率(83.53％)显著高于对照组(51.76％),差异有统计学意义(P＜0.05);观察组患者治疗后的平均骨折愈合时间(12周)较对照组(8周)长,差异有统计学意义(P＜0.05);但腕关节主动活动度显著高于对照组(P＜0.05);观察组患者手术前后各项影像学测量指标差值均显著高于对照组(P＜0.05).结论 掌侧入路角度锁定接骨板是治疗不稳定型桡骨远端骨折的有效治疗方法,患者术后病情改善与功能恢复情况良好.“,”Objective To investigate the clinical outcomes of stable fixation with a volar locking plating system in the treatment of unstable distal radius fractures.Methods A total of 170 patients with unstable distal radius fractures who received treatment in our hospital were included in this study.These patients were divided into an observation group (n =85) and a control group (n =85) according to treatment methods.Patients in the observation group were treated surgically with a volar locking plating system, while patients from the control group underwent closed reduction and external fixation.Treatment results and fracture union were compared between the observation and control groups.Wrist functional recovery was evaluated and rated using the Gartland-Werley scoring system.Radiological measurements were compared before and after the treatment and between these two groups.Results The excellent and good rate (83.53％)of the volar locking plate fixation group was significantly higher than that of the closed reduction and external fixation group(51.76％) (P ＜ 0.05).In the observation group, the me an time to achieve fracture union was 12 weeks while that in the control group was 8 weeks.The difference was significant (P ＜ 0.05).The active range of motion of the wrist was significantly greater in the observation group than in the control group (P ＜ 0.05).The imaging measurement differences before and after the treatment in the observation group were significantly greater than in the control group (P ＜ 0.05).Conclusion Stable fixation with a volar locking plating system is an effective treatment method for unstable distal radius fractures with improved in postoperative conditions and satisfactory functional recovery.
