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. Key words: hip displacement, cerebral palsy, hip reduction.

The authors describe a case report of a 5-year-old foreign girl with a rare bilateral hip dislocation after a car accident. Young surgeons at the emergency department performed an unsuccessful closed reduction. Since the clinical and ultrasound screening of DDH of all newborns in the Slovak Republic is carried out until the age of 4-6 weeks, the treatment of dislocated hips starts early and the late diagnosed dislocations occur rarely. The aim of the study is to point at differences in DDH screening all over Europe resulting in an increased risk of misdiagnosed patients. Key words:hip dislocation, childhood, trauma, DDH, screening.
