股骨头坏死老年患者全髋关节置换术后并发股内收肌挛缩的影响因素分析

Influencing factors of contracture of adductor femoris after total hip arthroplasty in elderly patients with femoral head necrosis

目的探讨股骨头坏死老年患者全髋关节置换术后并发股内收肌挛缩的影响因素。方法抽取2020年1月至2021年12月郑州市骨科医院收治的行全髋关节置换术的老年股骨头坏死患者88例,分析术后股内收肌挛缩出现者(44例)与未出现者(44例)临床资料的差异性,将差异有统计学意义的项目代入Logistic回归方程计算,分析术后并发股内收肌挛缩的影响因素。结果术后股内收肌挛缩出现者与未出现者性别、年龄、病因比较差异未见统计学意义(P>0.05),两者中是否牵引有效、手术入路、是否开展功能锻炼、有无手术史、肢体短缩度比较差异有统计学意义(P<0.05)。Logistic回归方程计算结果显示,是否牵引有效、手术入路、是否开展功能锻炼、有无手术史、肢体短缩度是股骨头坏死老年患者全髋关节置换术后并发股内收肌挛缩的影响因素(P<0.05)。结论股骨头坏死老年患者全髋关节置换术后并发股内收肌挛缩的影响因素多样,主要包括是否牵引有效、手术入路、是否开展功能锻炼、有无手术史、肢体短缩度。

Objective To investigate the influencing factors of contracture of adductor femoris after total hip arthroplasty in elderly patients with femoral head necrosis.Methods A total of 88 elderly patients with femoral head necrosis who underwent total hip replacement in Zhengzhou Orthopedics Hospital from January 2020 to December 2021 were selected.The differences in the clinical data of patients with contracture of adductor femoris(44 cases)and patients without contracture of adductor femoris(44 cases)were analyzed.The items with statistically significant differences were substituted into the logistic regression equation to analyze the influencing factors of development of contracture of adductor femoris after total hip arthroplasty.Results There was no significant difference in gender,age,and etiology between patients with and without contracture of adductor femoris(P>0.05).There were statistically significant differences in traction effectiveness,surgical approach,functional exercise,operation history,and limb shortening between patients with and without contracture of adductor femoris(P<0.05).The calculation results of the logistic regression equation showed that traction effectiveness,surgical approach,functional exercise,operation history,operation history and limb shortening were the influencing factors for the contracture of adductor femoris after total hip arthroplasty in elderly patients with femoral head necrosis(P<0.05).Conclusions There are various influencing factors for development of contracture of adductor femoris in elderly patients with femoral head necrosis after total hip arthroplasty,mainly including traction effectiveness,surgical approach,functional exercise,operation history,and the degree of limbs shortening.
