Outcome of surgical management of late presenting developmental dysplasia of hip with pelvic and femoral osteotomies

Introduction: Patients with Developmental dysplasia of hip many a times present later in the age due to missed or delayed diagnosis. The treatment of DDH is mainly dependent upon the age of the child at the time of presentation and varies according to it. In the late presenting cases it is mostly surgical with open reduction alone or in combination with pelvic and femoral osteotomies. Materials and Methods: This study between October 2012 and October 2014 includes 21 patients with unilateral dysplastic hips, surgically treated with a single stage procedure of open reduction and Acetabuloplasty of Pemberton, along with Varus derotation osteotomy and femoral shortening when necessary. Preoperatively they were classified according to Tonnis grade. Clinical assessment was done using Modified McKay's criteria; Radiological evaluation was done using Severin's radiographic criteria. Results: The mean follow up period was 15.14 months and the mean age at surgery was 66.86 months. McKay's grades were excellent in 8 hips, good in 11 hips, fair in 1 hip and poor in 1 hip. Severin's score was excellent in 4 hips, good in 15 hips, fair in 1 hip and poor in 1 hip. Conclusions: Every case of DDH is unique. The type of surgery chosen depends on the clear understanding of each hip after using the available resources. The combination of open reduction with pelvic and/ or femoral osteotomy when needed gives good immediate stability and promotes remodelling. This surgery is a technically demanding procedure but when performed properly by an experienced surgeon, it does give satisfactory results.
