The surgical dislocation approach is useful in assessing and treating proximal femoral hip deformities commonly due to pediatric
conditions. We sought to demonstrate the efficacy and problems associated with this technique. Diagnoses included slipped
capital femoral epiphysis, Perthes disease, developmental dysplasia of the hip, osteonecrosis, and exostoses. Through this
approach, femoral head-neck osteoplasty (22), intertrochanteric osteotomy (eight), femoral head-neck osteoplasty plus intertrochanteric
osteotomy (15), femoral neck osteotomy (five), open reduction and internal fixation of an acute slipped capital femoral epiphysis
with callus resection (five), open reduction and internal fixation of an acetabular fracture (one), trapdoor procedure (one),
and acetabular rim osteoplasty (one) were performed. The average patient age was 16 years. The minimum followup was 12 months
(average, 41.6 months; range, 12–73 months). Patients with Perthes disease and SCFE had preoperative and postoperative WOMAC
scores of 9.6 and 5.1, and 7.9 and 3.5 respectively. In patients with unstable SCFEs, the average postoperative WOMAC score
was 1.2. Seven patients underwent THAs and two patients underwent hip fusion. Complications in the 58 procedures included
four cases of osteonecrosis: three after femoral neck osteotomy and one after intertrochanteric osteotomy. The surgical dislocation
technique can be utilized to effectively treat these deformities and improve short-term symptoms. Although the technique is
demanding, we believe surgical dislocation offers sufficient advantages in assessing and treating these complex deformities
that it justifies judicious application.
