PURPOSE OF THE STUDY:
Hip dislocation is one of the major causes of disability in children with cerebral palsy (CP). Surgical treatment can be achieved using different techniques including proximal femoral varus derotation osteotomy (FVDRO), pelvic osteotomies, and open hip reduction (OHR). However, we claim that pathologies originating from extraarticular structures in the dislocated hip in CP can be reconstructed by extraarticular methods and OHR may not always be necessary. Therefore, this study aims to discuss the results of hip reconstruction with extraarticular intervention in patients with CP.

MATERIAL AND METHODS:
In total, 141 hips (95 patients) were included in the study. All patients underwent FVDRO, either with or without a Dega osteotomy. Changes in the Acetabular Index (AI), Migration Index (MI), neck-shaft angle (NSA), and center-edge angle (CEA) were assessed on the preoperative, postoperative, and final follow-up anterior-posterior radiographs of the pelvis.

RESULTS:
Median age was 8 years (range between 4-18 years). The average follow-up duration was 5 years (range between 2-9 years). Changes in AI, MI, NSA and CEA values were statistically significant for postop and follow-up periods when compared to preoperative values. Of the 141 operated hips, 8 (5.6%) hips required revision surgery due to redislocation/resubluxation detected at the follow-ups, and unilateral operation can be accepted as a risk factor for redislocation.

CONCLUSIONS:
Our results demonstrate that reconstructive treatment consisting of FVDRO, medial capsulotomy (in the case of reduction difficulty) and transiliac osteotomy (in the case of acetabular dysplasia) provides satisfactory outcomes in hip dislocation in CP.
