目的:探讨小儿髋部锁定加压接骨板(LCP)治疗小儿髋关节发育异常(DDH)的疗效优势。方法:回顾性分析在我院行LCP治疗的DDH患者20例(22髋),根据内固定系统的不同,分为角度钢板固定组(对照组)21髋和LCD固定组(观察组)22髋。比较两种固定方式对股骨截骨矫正前倾角以及颈干角后的固定疗效。结果:两组患儿术后前倾角及颈干角与术前比较有明显改善(P<0.05),但是观察组改善情况优于对照组(P<0.05)。术后根据Mckay标准对髋关节功能进行评分,对照组:优11髋(52.4%),良5髋(23.8%),可4髋(19.0%),差1髋(4.8%),优良率为76.2%;观察组:优15髋(68.2%),良5髋(22.7%),可2髋(9.1%),差0髋(0%),优良率为90.9%,两组患者优良率较差异有统计学意义(P<0.05)。结论:髋部锁定加压接骨板治疗小儿髋关节发育异常固定牢靠,患儿髋关节功能恢复满意,愈合良好,是一种安全可行的手术固定方法。
Objective: To investigate the efficacy of pediatric hip-locking compression plate (LCP) in the treatment of pediatric hip dysplasia (DDH). Methods: Twenty patients (22 hips) with DDH treated with LCP in our hospital were retrospectively analyzed. Twenty-two hips of angle plate fixation group (control group) and 22 hips of LCD fixation group (observation group) were divided according to different internal fixation system . To compare the two fixed fixation of femoral osteotomy for correction of anteversion and neck fixation effect. Results: The anteversion and neck angle were significantly improved in both groups (P <0.05), but the improvement in the observation group was better than that in the control group (P <0.05). Hip joint function was evaluated according to Mckay criteria after operation. The control group included 11 hips (52.4%), 5 hips (23.8%), 4 hips (19.0%) and 1 poor hip (4.8%). 76.2% of the patients in the observation group were excellent in 15 hips (68.2%), good in 5 hips (22.7%), fair in 2 hips (9.1%) and poor in 0 hips (0%), excellent and good rate was 90.9% The difference was statistically significant (P <0.05). Conclusion: Hip locking compression plate treatment of pediatric hip dysplasia fixed firmly, satisfactory functional recovery of the hip in children, healed well, is a safe and feasible surgical fixation method.
