Accurate limb-length equalization during total hip arthroplasty.

摘要: A method of equalization limb lengths during total hip arthroplasty (THA) was developed that uses the concept precise reproduction position femur in space (abduction/adduction) by use a carpenter's level. Precise femoral allows accurate measurement distance between pelvis and before dislocation after trial component placement allowing change pelvis. Accordingly, length can be maintained or adjusted to match contralateral side with increased accuracy. prospective study performed 117 consecutive patients undergoing THA assess accuracy an intraoperative limb-length measuring device. Patients were sequentially randomized into two groups. Group underwent without device, group B using Radiographic assessments measured Williamson Reckling. The hips had statistically significant decrease inequality compared (P 12 mm (P<.01). Eighty-four within 6 30% patients. Twenty-four percent 7% symptomatic required heel lift
