Femoral head and neck deformities of the hip joint are usually seen as a sequale of diseases in childhood such as Legg-Calvé-Perthes, slipped capital femoral epiphysis, developmental dysplasia of the hip and septic arthritis. On the other hand, avascular necrosis of the femoral head can result in formation of deformity in adulthood.

The patients are eligible for the femoral head and neck reconstruction if; physis are closed, range of motion of hip movements are close to full, there is no or minimally cartilage degeneration of the acetabulum, hip joint is painful, femoral head-neck ratio is increased, there is a lesion which prevents motion and the patient has capacity to adapt him/herself to the rehabilitation programme.
