The aim of the study was evaluation of residual deformity after neonatal septic arthritis of the hip. The patient was operatively treated by intetertrochanteric osteotomy of valgisation of 350 with anterotation of 100 and extension 250 at age of nine years because of leg length discrepancy, changes in the femoral neck, coxa vara, plana and breva. It was delay in diagnosis and failure to begin treatment promptly in the neonatal period. Delay in the diagnosis and the treatment of septic arthritis can result in disastrous complication like in this case report.
