股骨偏心距变化对髋关节置换后相关并发症的影响 摘要 目的 探讨股骨偏心距和髋关节置换术后并发症的相关性，了解股骨偏心距对髋关 节置换术的重要性。 方法 比较股骨颈骨折患者行髋关节置换术后健侧与患侧股骨偏心距，随访 61 例 2009年6月～2011年7月股骨颈骨折行髋关节置换术病例，根据健侧和患侧股骨 偏心距的差值分为A组（患侧股骨偏心距与健侧差值D＞4mm）、B组（患侧股骨偏 心距与健侧差值D≤4mm）。 结果 A 组 31 例：疼痛 4 例、脱位 0 例，跛行 2 例，双下肢不等长 6 例，B 组 30 例：疼痛1例、脱位0例，跛行0例，双下肢不等长1例。 结论 人工髋关节置换术股骨偏心距的有效重建与髋关节置换术后相关并发症存 在密切关系，良好股骨偏心距的恢复可明显减少髋关节术后相关并发症的发生。 关键词 人工全髋关节置换术；股骨偏心距；脱位；跛行；疼痛 2 Effect of femoral offset in complications after total hip arthroplasty Abstract Background As a test indicator of total hip arthroplasty, Femoral offset has played an important role on the efficiency of total hip arthroplasty and the life expectancy of Prosthesis. However, the general study of which the effective recovery of femoral offset after total hip arthroplasty taking the effect at the complications ,such as Lower limb length inequality , pain, loosening , dislocation and the impact syndrome and so on, is not adequate. Objective To investigate the correlation between the femoral offset and the complications of hip replacement surgery, the objective of this study was to assess and understand the importance of femoral offset on hip replacement surgery. Methods Comparing the femoral offset between healthy side and affected side of patients with femoral neck fracture after hip arthroplasty, 61 cases were followed up from June 2009 to July 2011. According to the difference of femoral offset between healthy side and affected side, group A (discrepancy4mm) and group B (discrepancy4mm) was divided. Results Group A of 31 patients: the complications of pain、dislocation、 claudication and dou
