- Abstract:
- ObjectiveTo explore the outcomes of children with developmental dysplasia of the hip (DDH) after closed reduction and dynamic cast immobilization.MethodsWe retrospectively reviewed a total of 276 DDH children with a total of 308 hips and a mean age of 15.3±4.4 months undergoing closed reduction and dynamic cast immobilization.Radiological examination was performed during each followup visit for assessing the redislocation rate and the presence of avascular necrosis (AVN) of femoral epiphysis (Kalamchi and MacEwen method).Final radiographic results were evaluated with the Severin classification.ResultsThere was a redislocation rate of 5.5%(17/308).The redislocation rate in Tnnis grade Ⅱ hips was significantly lower than that in Tnnis grades Ⅲ & Ⅳ hips (P=0.027).The overall AVN rate was 11.7% (grade Ⅱ:22 hips; grade Ⅲ:11 hips; grade Ⅳ:3 hips).At the final followup,the mean acetabular index was 21.0°±6.1°.And 79.9% of hips achieved satisfactory outcomes (74.4% Severin type Ⅰ vs 5.5% type Ⅱ),and 20.1% had unsatisfactory outcome (19.1% type Ⅲ vs 1% type Ⅳ).ConclusionDynamic cast is a viable alternative to spica cast immobilization for DDH children after closed reduction.It has similar redislocation and AVN rates compared to standard spica cast immobilization.
