Crowe IV complete dislocated hips were thought to be difficult for primary THA. Correction for leg length discrepancy associated with nerve palsy or tough to reduction during surgery. Purpose of this study was to evaluate 3.5cm total leg length correction for any type of Crowe IV patients setting in anatomical positioning of acetabular cup with femoral shortening osteotomy. 24 hips were evaluated averaged 28 months after primary THA. Correction length of center of rotation, amount of femoral shortening, Harris hip score, and abductor muscle power recovery with MicroFet 2 caluculator. Bilateral cases were preformed with 6 months interval. Length of femur and tibia compared to contralateral normal side were evaluated from plain radiograms.Purpose
Materials & Methods
Dysplastic acetabulum (DDH) have some difficulty even if with conventional approach of THA. Indication or contraindication is not clear with MIS THA. The purpose of this study was to evaluate complications with mini antero-lateral approach for DDH patients. 1523 DDH hips were evaluated. Follow-up periods were averaged 36 mos. (24–74). 612 were Crowe I, 628 of II, and 283 of III. Crowe IV hips were contra-indicated. Leg length discrepancy (LLD) before and after surgery, OR time, complications during and after surgery, and length of hospital stay were evaluated.Purpose
