摘要

目的

探讨人工股骨头置换术中下肢长度不同均衡策略对髋关节功能及术后双下肢长度的影响。

方法

选取86例行单侧人工股骨头置换术的患者，根据术中采用的下肢长度均衡策略分为对照组和改良组，每组43例，对照组按照传统方法均衡下肢长度，改良组以健侧头颈比为对照均衡下肢长度。比较2组患者手术一般情况、手术前后双下肢长度差异、Harris评分、满意率、步态、并发症发生率。

结果

改良组手术时间、术中出血量、住院费用及住院时间等手术一般情况与对照组比较，差异均无统计学意义（

0.05）；2组术后双下肢长度差异均较术前缩小（

0.05），且改良组术后双下肢长度差异小于对照组（

0.05）；2组术后Harris评分均高于术前（

0.05），且改良组高于对照组（

0.05）；改良组满意率为97.67%，高于对照组的81.40%（

0.05）；改良组术后步频、单腿支撑时间、步速均高/长于对照组（

0.05）；改良组术后并发症发生率为2.33%，与对照组的6.98%比较，差异无统计学意义（

0.05）。

结论

人工股骨头置换术中以健侧头颈比为对照可有效均衡下肢长度，减少双下肢长度差异，增强髋关节功能重建效果，提升患者满意率，改善患者步态，安全可靠。

Abstract

Objective

To investigate the effects of different lower limb length equalization strategies during artificial femoral head replacement on hip function and postoperative bilateral lower limb length.

Methods

A total of 86 patients who underwent unilateral artificial femoral head replacement were selected and divided into the control group and the modified group according to different lower limb length equalization strategies adopted during the operation

with 43 cases in each group.The lower limb length in the control group was equalized by traditional method

and the lower limb length in the modified group was equalized by the head neck ratio of the healthy side.The general conditions of surgery

the difference of lower limb length before and after surgery

Harris score

satisfaction rate

gait and incidence of complications of the two groups were compared.

Results

There was no significant difference between the two groups in terms of operation time

intraoperative blood loss

hospital expenses or hospital stay (

0.05).The postoperative difference of lower limb length of the two groups were reduced compared with those before surgery (

0.05)

and the postoperative difference of lower limb length in the modified group was less than that in the control group (

0.05).The Harris scores after surgery in both groups were higher than those before surgery (

0.05)

and the modified group was higher than the control group (

0.05).The satisfaction rate in the modified group was 97.67%

which was higher than 81.40% in the control group (

0.05).The postoperative stride frequency

single leg support time and step speed in the modified group were higher/longer than those in the control group (

0.05).The postoperative incidence of complications in the modified group was 2.33%

which was no statistically significant difference compared with 6.98% in the control group (

0.05).

Conclusion

In artificial femoral head replacement

using the head neck ratio of the healthy side as a control can effectively equalize the the lower limb length

reduce the difference of bilateral lower limb length

enhance the effect of hip functional reconstruction

increase the patients' satisfaction rate

and improve the patients' gait

which is safe and reliable.
