Abstract: (208 Views)
Background: Total hip arthroplasty (THA) is a highly successful orthopedic procedure, recognized as the gold standard for addressing advanced osteoarthritis, with a projected global increase in performed cases.
Objectives: This study investigated the accuracy of cup positioning in patients undergoing THA using the anterolateral (AL) approach.
Methods: This cross-sectional study included patients undergoing ALTHA at Shafa Yahyaiyan Hospital in Tehran, affiliated with the Iran University of Medical Sciences, from 2018 to 2023. Post-operative radiological evaluations were conducted, and anteversion and inclination were assessed using established protocols. A safe zone for cup orientation was defined with an inclination angle of 40±10° and anteversion angle of 15±10°.
Results: Among 91 patients, the mean age was 51.14 years and 48 cases (52.7%) were male. Considering the safe zone for cup orientation, 69 patients (75.8%) fell within the inclination angle safe zone and 46(50.5%) were within the anteversion angle safe zone. However, no significant associations were found between age, gender, side of operation and the safe zones for anteversion and inclination.
Conclusion: The results indicated that the AL approach, as performed by experienced surgeons, achieved favorable cup positioning in the majority of patients, regardless of age and gender.
