摘要
目的从腕关节影像和功能角度评估自制动力性外固定器治疗桡骨远端骨折的疗效。方法外固定器治疗12例桡骨远端骨折,AO分类B1型2例,C1型3例,C2型3例,C3型4例,随访时间3～6个月。手术后3个月,测量腕关节的活动范围和影像学指标,采用Sarmiento评分评估外固定器的疗效。结果术后3个月,腕关节的活动范围较对侧正常腕关节相比无显著性差异(P>0.05),恢复百分比为81.6%～95.4%。桡骨高度和桡偏角较对侧正常腕关节相比无显著性差异(P>0.05),恢复百分比为87.9%～89.8%。掌倾角仅仅恢复68.2%,显著小于对侧正常腕关节(P<0.05)。Sarmiento功能评分优5例,良6例,一般1例;复位评分:优6例,良5例,一般1例。出现1例钉道表浅感染。结论新型外固定器能有效维持桡骨远端骨折的复位,恢复腕关节功能。
Objective To evaluate the efficacy of our self-developed dynamic external fixator for treating distal radius fracture by means of wrist joint radiographic and functional perspectives. Methods The external fixator was used in 12 cases with distal radius fracture. AO classifications were type B1 in 2 cases, type C1 3 cases, type C2 3 cases and type C3 4 cases. The patients were followed up for 3-6 months after surgery. Three months following the surgery, the movement range.of the wrist joint and its radiographic indexes were measured,and the efficacy of our external fixator was evaluated by Sarmiento method. Results Three months after the surgery,compared with that of the normal hand,no significant difference was seen in the movement range of treated wrist joint with a recovery percentage of 81.6-95.40/00, and in the radial height and radial inclination with a recovery percentage of 87.9 %-89.8%. Yet the recovery of the palm tilt of treated joint was 68.2%, which was significantly smaller than that of the normal（P〈0. 05）. Sarmiento functional evaluation was excellent in 5 cases,good in 6 cases, and average in 1 case, and the assessment of reduction was excellent in 6 cases, good in 5 cases, and average in 1 case. Conclusion Our novel external fixator can effectively maintain the reduction for distal radius fracture,and restore the functions of the wrist joint.
