摘要:

背景:全髋关节置换后股骨偏心距以及髋距旋转中心的恢复和重建直接影响患者的关节功能。但是,目前临床上关于全髋关节置换后股骨偏心距改变对患者疼痛及关节功能的影响尚缺乏研究。
目的:探讨股偏心距改变对全髋关节置换后关节疼痛及其功能恢复的影响。
方法:对162例全髋关节置换患者资料进行分析,根据患者置换侧与健侧偏心距差距值分为3组,减小组30例置换侧偏心距和健侧< -5 mm;正常组87例置换侧和健侧偏心距差距在-5-5 mm;增加组45例置换侧偏心距和健侧> 5 mm。比较各组股骨柄及骨头假体类型,评估患者置换前后SF-12量表评分、骨关节炎指数评分(WOMAC)及Harris评分,并进行对比分析。
结果与结论:减小组、正常组以及增大组更多的以标准偏心距股骨柄假体为主,分别占77%,63%,73%(P > 0.05);各组患者置换侧与健侧股骨柄假体平均股骨偏心距差异无显著性意义(P > 0.05)。3组患者置换后WOMAC评分和置换前相比均明显提高(P < 0.05);置换前3组之间WOMAC评分差异无显著性意义(P > 0.05);置换后3组相关疼痛、僵硬等差异无显著性意义(P > 0.05),躯体功能差异有显著性意义(P < 0.05),正常组躯体功能评分最高。3组患者置换前后SF-12量表评分差异无显著性意义(P > 0.05);置换后3组患者体能评分和置换前相比均得到提高(P < 0.05);而精神评分除增大组外均得到显著提高(P < 0.05)。增大组Harris评分优良率为96%,显著高于减小组(70%)和正常组(87%),差异有显著性意义(P < 0.05)。提示偏心距增大更加有利于全髋关节置换后疼痛缓解,促进功能恢复;偏心距减小则会加剧患者疼痛,不利于置换后关节功能恢复。

Abstract:

BACKGROUND: Recovery and reconstruction of femoral eccentricity and hip rotation center after total hip arthroplasty directly affect joint function. However, there is lack of studies on the effects of femoral eccentricity on pain and joint function in patients undergoing total hip arthroplasty.

OBJECTIVE: To explore the effects of femoral eccentricity changes on joint pain and functional recovery after total hip arthroplasty. 
METHODS: Data of 162 cases after total hip arthroplasty were analyzed. Patients were divided into three groups according to the difference of femoral eccentricity on the affected and healthy sides. In the reduction group (30 cases), the difference value was < -5 mm. In the normal group (87 cases), the difference value was -5-5 mm. In the increased group (45 cases), the difference value was > 5 mm. Femoral stem and femoral prosthesis type were compared among different groups. SF-12 scale score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Harris score were evaluated and compared before and after replacement. 

RESULTS AND CONCLUSION: Standard eccentricity of femoral prosthesis mainly accounted for 77%, 63% and 73% in the reduction group, normal group and increased group, respectively (P > 0.05). No significant difference in average eccentricity was detected in each group between the affected and healthy sides (P > 0.05). WOMAC score was significantly higher after replacement than that before replacement in three groups (P < 0.05). No significant difference in WOMAC score was found among three groups before replacement (P > 0.05). No significant differences in pain and stiffness were detected among three groups after replacement (P > 0.05), and significant differences in physical function were found (P < 0.05). The physical function was highest in the normal group. No significant difference in SF-12 scale score was seen in the three groups before and after replacement (P > 0.05). The physical ability score was elevated after replacement in the three groups (P < 0.05). Mental scores were significantly elevated in reduction and normal groups (P < 0.05). The excellent and good rate of Harris score was significantly higher in the increased group (96%) than in the reduction group (70%) and normal group (87%) (P < 0.05). These findings indicate that the increased eccentricity contributed to the pain easement after total hip arthroplasty and promoted functional recovery. The decreased eccentricity could worsen patient’s pain, and was not conducive to the restoration of joint function after replacement.
