Abstract

Objectives: This study aims to describe our standardized method for evaluating the tension of reduction around the hip joint during open reduction in patients with developmental dysplasia of the hip (DDH).

Patients and methods: We retrospectively evaluated 67 pediatric patients (8 males, 59 females; mean age 21.9±11.1 months; range, 9 to 67 months) who were performed open reduction or open reduction with concomitant pelvic and/or femoral osteotomy for DDH at our clinic between January 2009 and March 2014. The amount of distraction between femoral head and acetabulum was measured to evaluate the tension of reduction during surgery. Factors associated with avascular necrosis (AVN) such as age at reduction, presence of concomitant pelvic and/or femoral shortening osteotomy, and severity of dislocation were determined.

Results: Statistically significant association was found between the presence of femoral osteotomy, severity of dislocation, and amount of distraction and AVN. The incidence of AVN was 38.8% (10 grade I, 12 grade II, 3 grade III, and one grade IV AVN). Cut-off value for the amount of distraction to prevent the development of AVN was calculated as 4 mm.

Conclusion: According to our study findings, we advise using our technique for the evaluation of the tension of reduction around the hip joint and performing tension free reduction in the treatment of DDH to minimize the risk of AVN development.

一种评估髋关节发育不良患者切开复位时复位张力的新方法。
目的:本研究旨在描述我们在髋关节发育不良(DDH)患者切开复位期间评估髋关节周围复位张力的标准化方法。患者和方法:我们回顾性评估了67例儿科患者(男8例,女59例;平均年龄21.9±11.1个月;2009年1月至2014年3月期间在我们诊所接受切开复位或切开复位合并骨盆和/或股骨截骨治疗DDH的患者(9至67个月)。术中测量股骨头与髋臼间牵张量以评估复位张力。与缺血性坏死(AVN)相关的因素,如复位时的年龄,骨盆和/或股骨短截骨术的存在,以及脱位的严重程度被确定。结果:股骨截骨术、脱位严重程度、牵张量和AVN之间存在统计学意义的关联。AVN发生率为38.8% (I级10例,II级12例,III级3例,IV级1例)。结论:根据我们的研究结果,我们建议使用我们的技术来评估髋关节周围的张力复位,并在DDH治疗中进行无张力复位,以尽量减少AVN的发生风险。
