我们进行这项研究是为了确定各种机械和患者相关因素对初次全髋关节置换术（THA）后脱位发生率的相对影响。在2,023例THA中，21例至少发生I型脱位的患者与21例无脱位的对照组进行比较，年龄、性别、病理学和手术年份匹配。记录植入物定位、外科医生资历、美国麻醉医师协会（阿萨）评分和运动协调性下降。数据分析包括单因素和多因素分析。如果总前倾不在40 °和60 °之间，脱位风险高6.9倍，阿萨评分高的患者高10倍。外科医生应注意THA的总前倾（髋臼杯和股骨柄）。阿萨评分应作为脱位风险术前评估的一部分。
We conducted this study to determine the relative influence of various mechanical and patient-related factors on the incidence of dislocation after primary total hip asthroplasty (THA). Of 2,023 THAs, 21 patients who had at least I dislocation were compared with a control group of 21 patients without dislocation, matched for age, gender, pathology, and year of surgery. Implant positioning, seniority of the surgeon, American Society of Anesthesiologists (ASA) score, and diminished motor coordination were recorded. Data analysis included univariate and multivariate methods. The dislocation risk was 6.9 times higher if total anteversion was not between 40degrees and 60degrees and 10 times higher in patients with high ASA scores. Surgeons should pay attention to total anteversion (cup and stern) of THA. The ASA score should be part of the preoperative assessment of the dislocation risk.
