Roentgenoanatomy of the hip joint following reconstructive intervention in children with spastic cerebral palsy

Objective Explore changes in roentgenoanatomical parameters of the pediatric hip joint following multilevel reconstructive surgeries performed for CP patients in combination with derotation varus osteotomy (DVO) alone or DVO and acetabuloplasty (AP). Material and methods The study included 49 children (30 GMFCS level IV and 19 GMFCS level V patients). Either DVO (n = 28, 44 joints, mean age 6.98 ± 2.2 years) or DVO and AP (n = 21, 38 oints, mean age 7.0 ± 2.04 years) were produced in combination with multilevel reconstructive surgeries to eliminate contractures of the knee and ankle joints and correct foot deformities. The acetabular angle, the Reimers' index, the acetabular depth ratio (ADR), the Wiberg center-edge angle were measured preoperatively, straight after surgery and at 1, 2, 3 years postsurgery. Results Normal relationship between the femoral head and acetabulum persisted at a long-term follow-up. The parameters evaluating acetabular morphology (Wiberg angle, AI and ADR) were shown to improve or remain stable...
