THA Following Pediatric Hip Diseases (Legg-Calvé-Perthes/Slipped Capital Femoral Epiphysis)
Legg-Calvé-Perthes disease (LCPD) represents a type of idiopathic avascular necrosis of the femoral head which typically develops during childhood [1, 2]. Its etiology is considered to be multifactorial but is generally unknown; genetic, constitutional, and environmental factors have been implicated . Despite receiving treatment, some patients initially develop morphological changes in the femoral head and secondarily acetabular deformity, femoroacetabular in congruency, and the abnormal hip movement that could lead to early-onset secondary osteoarthritis [1, 4]. In a current prospective cohort, 5% of LCPD patients underwent THA at 20 years after nonoperative treatment . Stulberg classification is used as prognostic tool of hip osteoarthritis at skeletal maturity ; Stulberg types III–V are more susceptible to the development of early secondary hip osteoarthritis .
