Abstract

Children having both typical developmental dysplasia of the hip (DDH) and clubfoot are rare, and early treatments of both conditions are recommended. The aim of this study was to evaluate the effects of the Ponseti method of clubfoot treatment on hips with DDH. After institutional review board approval, we identified children treated by the Ponseti and Pavlik methods between 2003 and 2016. During the Ponseti method treatment, the duration of manipulations, number of casts, tenotomies performed, and days in clubfoot orthosis were recorded. During DDH treatment, we registered duration for Pavlik and hip brace usage. Hips had dynamic sonography and radiographic evaluations. The cases were grouped according to the combination of DDH and clubfoot treatments: (a) concurrent, (b) sequential, and (c) hip observation. Seven cases of DDH and clubfoot were identified. The average number of Ponseti casts was 5.8 (range: 4-8 casts). The average number of days following the post-Achilles-tenotomy casting to the end of clubfoot bracing was 870 days (range: 90-1605 days). Eleven (four bilateral cases and three unilateral) clubfeet were corrected initially by the Ponseti method. The average number of days for Pavlik harness treatment was 74 (range: 10-126 days). Additionally, a hip orthosis was utilized in three children for an average of 131 days. At follow-up, all children had a high femoral neck-shaft angle averaging 152° (range: 144°-164°). One child (case 5) developed avascular necrosis of the femoral head, Kalamchi type I. Children with typical and nonsyndromic DDH and clubfoot treated by Pavlik harness and Ponseti methods are associated with abnormal hip development (coxa valga).
