Abstract：Objective To explore the effect of an improved acetabular anteversion abduction angle calibration system in total hip arthroplasty(THA) through different approaches.Methods We selected 64 patients with femoral head necrosis who underwent unilateral THA for the first time from January 2020 to December 2021 in the Osteoarthrology Department of Wuhan Integrated Traditional Chinese and Western Medicine Orthopedic Hospital as the research subjects.According to the surgical approach，patients were divided into a direct anterior approach(DAA) group(n＝31)，with 18 males and 13 females.The age ranged from 57~75 year，with an average of (61.8±7.2) years.Posterior approach(PA) group(n＝33) had 20 males and 13 females.The age ranged from 58~74 year，with an average of (63.4±8.3) years.Using the improved acetabular anteversion abduction angle calibration system，we evaluated the acetabular prosthesis position during and 1 week after surgery，and evaluate the Harris hip joint function score at 1 week and 6 months after surgery.The incidence of recurrent fractures，dislocations and lower limb venous thrombosis was recorded.Results There was no statistically significant difference in the comparison of acetabular abduction angle and anteversion angle between the two groups during and after surgery (P＞0.05).There was no statistically significant difference in Harris scores between the two groups after surgery (P＞0.05).There was no statistically significant difference in the incidence of postoperative complications between the two groups of patients (P＞0.05).Conclusion According to the modified acetabular anteversion abduction angle calibration system，the efficacy of THA surgery through PA and DAA approaches have comparable surgical outcomes 。
