Clinico-Radiological Evaluation of Legg-Calve-Perthes Disease Managed by Proximal Femoral Varus Derotation Osteotomy: A Retrospective Study

Abstract

Legg-Calve-Perthes disease is a juvenile idiopathic aseptic and non-inflammatory osteonecrosis of immature hip. It is associated with both substantial hip pain and dysfunction during the disease process as well as later in adulthood. The goals of treatment are to decrease pain, reduce the loss of hip motion, and prevent or minimize permanent femoral head deformity. Children with Perthes disease, of both genders were managed by proximal femoral varus derotation osteotomy. Evaluation was done in terms of; clinical symptoms and signs, Harris hip score, and radiologically with X-rays. The results indicated improvement in pain, limp, abduction, internal rotation and Harris Hip Score which was statistically significant.In conclusion, proximal femoral varus derotation osteotomy is an acceptable method for management of patients with Legg-Calve-Perthes disease. This surgery led to decrease in pain, limping, and an increase in range of motion.
