Bernese periacetabular osteotomy for hip dysplasia. A modification to original technique and South American...

Bernese periacetabular osteotomy has become a secure and reproducible technique for treatment of hip dysplasia. It allows an adequate reorientation of the acetabulum and coverage of the femoral head improving biomechanical conditions of the hip joint. We present a review of literature and a modification of original technique that includes a smaller incision and preservation of the abductor muscles and rectus femoris tendon insertion.
