Abstract
Thirty-one hips in 27 young girls, treated for developmental dysplasia of the hip in the authors' institute since 2003, showed persistent radiographic evidence of residual acetabular dysplasia. These hips were registered as candidates for pelvic osteotomy. A prospective study was conducted and these hips were evaluated by magnetic resonance imaging (MRI); the average age of the patients was 5 years. MRI measurement of acetabular angle and acetabular head index in 2 different landmarks (bone and cartilage) was performed. The results were correlated with plain radiographic film evolution. MRI studies revealed sufficient cartilaginous acetabular coverage in 27 hips, cartilaginous acetabular dysplasia in 2 hips, and short acetabulum in 2 others. The 27 hips with thick cartilage of the acetabular roof were subsequently followed up by plain radiographs. The average follow-up period was 2.1 years. The authors observed a spontaneous progressive ossification of the cartilaginous acetabular roof in all the 27 cases. In 4 cases, the correction of the acetabular angle was complete. They concluded that MRI promotes more accurate selection of patients for pelvic osteotomy and aids in the choice of the most appropriate type of osteotomy. Clinical imaging examples are presented and need to be further evaluated.
