Legg-Calve-Perthes disease is a juvenile idiopathic aseptic, non-inflammatory, osteonecrosis of immature hip in which the blood supply of femoral epiphysis is not sufficient and the bone dies provisionally followed by a subchondral fracture, fragmentation, revascularization and remodeling. 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. In the current study, authors evaluated the outcome of proximal femoral varus derotation osteotomy in children with Legg-Calve-Perthes disease.
Material & Methods:
All the children (up to 16 years) presenting with Perthes disease, of both sex and willing to get enrolled in the study and were managed by proximal femoral varus derotation osteotomy were included in the study. Evaluation were done in terms of clinical symptoms and signs, Harris hip score and radiologically with X-rays.
The study results indicated improvement in pain, limp, abduction, internal rotation and Harris Hip Score which was statistically significant in the study subjects.
According to this study, proximal femoral varus derotation osteotomy is an acceptable method for management of patients with Legg-Calve-Perthes disease in all age group of patients. This surgery led to decrease in pain, limping, and increase in range of motion.
