BACKGROUND
The purpose of this study was to evaluate the efficacy of Pavlik harness treatment in patients with bilaterally dislocated Graf type IV hips and compare them to cases with unilaterally dislocated hips.
METHODS
Twenty-one patients (42 hips) who presented with bilaterally dislocated hips with no prior treatment were studied. The comparison group consisted of 33 patients (33 hips) with unilateral hip dislocation treated with the same protocol. Successful treatment was defined as relocation of the hips within 3 weeks of Pavlik harness application.
RESULTS
Twelve of 21 patients (57%) in the bilateral group (6 failed bilaterally, 6 unilaterally) and 18/33 patients (54.5%) in the unilateral group failed harness treatment.
CONCLUSIONS
The use of the Pavlik harness in dislocated hips is associated with a high failure rate. Patients presenting with bilaterally dislocated hips however, are at no greater risk for failure than patients presenting with unilateral hip dislocation.
LEVEL OF EVIDENCE
Level III.
背景
本研究旨在评估帕夫利克吊带治疗双侧脱位的格拉夫IV型髋关节患者的疗效，并将其与单侧脱位髋关节的病例进行比较。
方法
对21例（42髋）未经治疗的双侧脱位髋关节患者进行研究。对照组由33例（33髋）采用相同方案治疗的单侧髋关节脱位患者组成。成功治疗定义为在应用帕夫利克吊带后3周内髋关节复位。
结果
双侧组21例患者中有12例（57%）（6例双侧失败，6例单侧失败），单侧组33例患者中有18例（54.5%）吊带治疗失败。
结论
在脱位髋关节中使用帕夫利克吊带失败率较高。然而，双侧脱位髋关节患者的失败风险并不比单侧髋关节脱位患者更高。
证据级别
III级。
