Intraoperative Measurement Technique for Improved Accuracy of Femoral Offset and Leg Length in Total Hip Replacement: A Retrospective Cohort Study
Intraoperative Measurement Technique for Improved Accuracy of Femoral Offset and Leg Length in Total Hip Replacement: A Retrospective Cohort Study
This retrospective cohort study included 50 consecutive patients who underwent THR. All surgeries were performed by the same orthopedic surgeon, using posterior approach. In all patients, the same technique of intraoperative measurement of the femoral offset and limb length was used, entailed calculation of the distances between reference points on the ischium, greater trochanter, and the screwdriver. Measurements were collected from radiographic imaging data and surgical reports.
Introduction: Restoration of limb length equality and femoral offset is critical for the success of THR. The purpose of this study was to investigate the efficacy of a novel intraoperative measurement technique in minimizing errors in leg length and offset in total hip replacement (THR).
Methods: This retrospective cohort study included 50 consecutive patients who underwent THR. All surgeries were performed by the same orthopedic surgeon, using posterior approach. In all patients, the same technique of intraoperative measurement of the femoral offset and limb length was used, entailed calculation of the distances between reference points on the ischium, greater trochanter, and the screwdriver. Measurements were collected from radiographic imaging data and surgical reports.
Inclusion Criteria:
* patients that underwent THR due to primary osteoarthritis of the hip joint.
Exclusion Criteria:
