摘　　要：目的:探讨应用自设计臼杯倾角测量器来辅助提高全髋关节置换术(THA)中髋臼臼杯置入角度(外展角和前倾角)的精准度。方法:选择2021年9月至2023年5月30例因髋关节疾病行全髋关节置换术治疗的患者,按随机分组法分为观察组(术中采用臼杯倾角测量器来测量髋臼臼杯所置入的外展角和前倾角,15例)和传统组(传统全髋关节置换术组,15例),两组术前规划其髋臼臼杯置入的外展角为40°、前倾角为20°,术后X线片测量两组臼杯假体的外展角和前倾角与术前规划的差异。结果:观察组术后髋臼臼杯外展角和前倾角与术前所规划角度之间的误差明显小于传统组,且组间差异有统计学意义(P<0.05)。结论:在全髋关节置换术中,采用臼杯倾角测量器对髋臼臼杯置入的外展角和前倾角进行测量与校正,能提高髋臼臼杯置入角度(外展角和前倾角)的精准度。Objective:To investigate the application of a self-designed device for measuring the cup inclination angle in order to enhance the accuracy of acetabular cup placement angles(abduction angle and anteversion angle)during total hip arthroplasty(THA).Methods:30 patients who underwent THA for hip joint diseases from September 2021 to May 2023 were selected were randomly divided into two groups:an observation group(15 cases)and a traditional group(15 cases).In the observation group,the cup inclination angle measurement device was used during the surgery to measure the abduction angle and anteversion angle of the acetabular cup placement,whereas the traditional group underwent the conventional THA procedure.The planned abduction and anteversion angles for both groups were set at 40°and 20°respectively.Postoperative X-ray films were utilized to measure the disparity between the actual abduction and anteversion angles of the acetabular cup prosthesis in each group and the preoperative planned angles.Results:The observation group demonstrated significantly smaller errors between the postoperative abduction angle,anteversion angle,and the preoperative planned angles compared to the traditional group.A statistically significant difference was observed between the two groups(P<0.05).Conclusion:In THA procedures,the implementation of the cup inclination angle measurement device to assess and correct the abduction angle and anteversion angle of the acetabular cup placement can notably improve the accuracy of the cup placement angles.
