目的：分析标准股骨假体行人工全髋关节置换术股骨假体颈长和股骨矩保留对偏心距重建的作用，并研究偏心距重建对软组织平衡的影响。
方法：68例(71髋，男30例，女38例；年龄17～89岁，平均63.5岁)行初次全髋关节置换术的患者并获得随访，采用Harris评分，Cybex-6000等速测定患髋外展肌力，测得偏心距、股骨矩、假体颈长，综合评估手术结果。
结果：假体颈长对偏心距的影响较股骨矩大(t=3.07,P<0.01),并与偏心距呈正相关关系(r=0.642,P<0.001,但两者对Harris评分影响的差异无统计学意义(t=0.22,P>0.05).股骨头坏死患者术后偏心距较髋关节骨性关节炎患者和股骨颈骨折患者小(t=2.91,3.31,P<0.01).偏心距获得重建的髋关节术后外展肌力较偏心距重建不足者优(P<0.05).
结论：采用标准股骨假体行全髋关节置换术，股骨假体颈长对人工全髋关节置换术后偏心距的重建作用大于股骨矩的保留，偏心距的重建在全髋关节置换术软组织平衡中主要起到增强术后外展肌力的作用。 |

| Effects of femoral offset on soft tissue balance in total hip arthroplasty |

Abstract:
Objective: To analysis the effects of restoring neck length and femoral calcar of femoral component on the reconstruction of femoral offset and its affection on soft tissue balance in total hip arthroplasty with standard femoral components.
Methods: Sixty-eight patients(71 hips,30 male and 38 female,ranging in age from 17 to 89 years,with an average of 63.5 years)undergone primary total hip arthroplasty were followed up. The postoperative hip scored according to Harris hip score symtem,and femoral offset,femoral calcar restored as well as neck length of femoral component were measured from the postoperative X-ray image,and the adductor muscle force was measured by Cybex-6000 isokinetic muscle strength testing system.
Results: Femoral neck length had highly significant and positive correlation with femoral offset(r=0.64,P<0.001),and had more effects on femoral offset than restoring femoral calcar(t=3.07,P<0.01),but had no significant difference on postoperative Harris score. The postoperative femoral offset of patients operated for the femoral head osteonecrosis was less than those for the hip osteoarthrosis(t=2.91,P<0.01)and the femoral neck fracture(t=3.31,P<0.01). The adductor muscle force in patients who restored femoral offset were better than those failed to restore femoral offset.
Conclusion: There are several factors affecting femoral offset restoration for soft tissue balance in total hip arthroplasty with standard femoral components,among them,the key factor is the neck length of femoral component which is more significant than femoral calar restoration for reconstruction of femoral offset. The role of femoral offset on soft tissue balance in total hip arthroplasty was strengthening the postoperative adductor muscle. |
