Abstract
A 57-year-old female with bilateral highly dislocated hips underwent bilateral total hip replacement (THR). On the left side, skeletal traction was conducted following muscle release, femur was pulled down 4cm and no complication prior to THR could be found. On the right side, muscle release, pulling down the femur and THR were performed simultaneously, since this would not be attended by any complication on the left side. On the both sides, components fitting the narrow acetabulums and femurs were selected and the socket was placed at the site of the original acetabulum. The patient has been able to walk with the aid of only a cane without pain for 2 years and 10 months on the left side and 2 years and 3 months on the right following the operation.
