BACKGROUND
Ulnar shortening osteotomy is a well-established treatment for ulnar impaction syndrome. Controversy remains regarding the most effective system to achieve efficient bony union, whilst minimising incidence of complications, particularly hardware irritation. We present outcomes at 2 years using the recently released low profile AO osteotomy system.
METHODS
32 consecutive patients with significant pain from ulnar impaction syndrome (idiopathic or post-traumatic), without degenerative changes of the distal radio-ulnar joint, were included. Time to union, range of motion, grip strength, pain and complications were recorded.
RESULTS
Median time to union was 10.14 weeks (9.27-11.01, 95%CI), with one nonunion. Visual Analogue Pain score, grip strength and range of motion improved significantly. No patient experienced hardware irritation. No plate required removal. Positive ulnar variance was reduced by 3.8 mm (mean).
CONCLUSIONS
The low profile AO system appears effective in achieving bony union whilst minimising incidence of hardware irritation, at a follow up of 2 years.
背景
尺骨短缩截骨术是治疗尺骨撞击综合征的一种成熟方法。关于实现有效骨愈合同时将并发症发生率降至最低，尤其是减少内固定刺激的最有效系统，仍存在争议。我们展示了使用最近发布的低轮廓AO截骨系统在2年时的结果。
方法
纳入32例因尺骨撞击综合征（特发性或创伤后）导致严重疼痛且桡尺远侧关节无退变改变的连续患者。记录愈合时间、活动范围、握力、疼痛和并发症情况。
结果
愈合的中位时间为10.14周（9.27 - 11.01，95%置信区间），有1例骨不连。视觉模拟疼痛评分、握力和活动范围显著改善。没有患者出现内固定刺激。无需取出钢板。正尺骨变异平均减少了3.8毫米。
结论
在2年的随访中，低轮廓AO系统似乎能有效实现骨愈合，同时将内固定刺激的发生率降至最低。
