Abstract：
UNASSIGNED: To evaluate the residual acetabular dysplasia in Graf type II hips after Pavlik harness treatment with a radiographic follow-up at 2 years of age.
UNASSIGNED: We retrospectively reviewed the developmental dysplasia of the hip patients who were treated with the Pavlik harness between March 2018 and February 2022. Patients with Graf type II hip dysplasia who had at least one radiographic follow-up after 2 years of age were included. The following information, sex, laterality, affected side, age at harness initiation, treatment duration, α angle, and the morphology of bony roof, was collected and studied. We evaluated the radiographic acetabular index at the last follow-up and defined the value of greater than 2 standard deviations as residual acetabular dysplasia.
UNASSIGNED: A total of 33 patients (53 hips) met the criteria. The mean initial α angle was 53.4°; the mean age at Pavlik harness initiation was 10.9 weeks. The mean treatment duration was 10 weeks. The mean α angle at the last ultrasound follow-up was 64.9°. The mean age of the last radiographic follow-up was 2.6 years, and 26 hips had a residual acetabular dysplasia with acetabular indexes greater than 2 standard deviations above the mean. The morphology of the acetabular bony rim (odds ratio = 4.333, P = 0.029) and age of initial treatment <12 weeks (odds ratio = 7.113, P = 0.014) were seen as significant predictors for a higher acetabular index more than 2 years of age.
UNASSIGNED: A notable incidence of residual acetabular dysplasia after Pavlik harness treatment in Graf type II hips, wherein the acetabular bony roof with a blunt rim at the end of treatment and initial age after 12 weeks were independent predictors associated with residual acetabular dysplasia.
UNASSIGNED: Therapeutic studies, IV.

摘要：
■评估在2岁时进行Pavlik线束治疗后GrafII型髋关节的残余髋臼发育不良。
■我们回顾性回顾了2018年3月至2022年2月期间接受Pavlik线束治疗的髋关节发育异常患者。包括GrafII型髋关节发育不良患者，这些患者在2岁后至少进行了一次影像学随访。以下信息，性别,偏侧性,患侧,线束开始时的年龄，治疗持续时间,α角,以及多骨屋顶的形态，收集和研究。我们在最后一次随访时评估了影像学髋臼指数，并将大于2个标准偏差的值定义为残余髋臼发育不良。
■共有33名患者（53髋）符合标准。平均初始α角为53.4°；Pavlik线束开始的平均年龄为10.9周。平均治疗时间为10周。末次超声随访平均α角为64.9°。最后一次影像学随访的平均年龄为2.6岁，和26个髋关节有残余的髋臼发育不良，髋臼指数高于平均值2个标准差。髋臼骨缘的形态（比值比=4.333，P=0.029）和初始治疗年龄<12周（比值比=7.113，P=0.014）被认为是髋臼指数高于2岁的重要预测因子。
■在GrafII型髋关节进行Pavlik治疗后，残余髋臼发育不良的发生率显着，其中在治疗结束时具有钝缘的髋臼骨顶和12周后的初始年龄是与残余髋臼发育不良相关的独立预测因子。
■治疗性研究，IV.
