Total hip arthroplasty involves division of the joint capsule, which can cause receptor damage, affecting postural stability and increasing the risk of falls. The aim of this study was to determine whether postural stability can be disturbed by total hip arthroplasty from a postero-lateral approach.
Static balance was quantified with the use of a two plate tensometric platform in a study group of 16 patients (8 women and 8 men) with unilateral hip osteoarthritis, mean age 57.13 (± 10.7) years, height of 173.38 (± 9) cm, weight 90.21 (± 16.9) and BMI of 30.07 (± 2.87) kg/m2.
Postural balance improved after surgery, with a statistically significant decrease in the length of the sway path in the AP plane and a strong trend towards significance in the medio- lateral plane. The maximum deflection of the COP from the 0 in the Y direction was reduced. The average velocity of movement of the COP along the Y-axis was significantly reduced, and velocity along the X-axis in mm/s was reduced with a strong trend towards significance.
全髋关节置换术涉及关节囊的切开，这可能导致感受器损伤，影响姿势稳定性并增加跌倒风险。本研究的目的是确定后外侧入路的全髋关节置换术是否会扰乱姿势稳定性。
使用双板张力测量平台对16例单侧髋骨关节炎患者（8名女性和8名男性）进行静态平衡量化，平均年龄57.13（±10.7）岁，身高173.38（±9）cm，体重90.21（±16.9）kg，体重指数为30.07（±2.87）kg/m²。
术后姿势平衡得到改善，前后平面内摆动路径长度在统计学上显著缩短，内外侧平面也有显著缩短的强烈趋势。重心在Y方向上相对于0点的最大偏移减小。重心沿Y轴的平均移动速度显著降低，沿X轴的速度（mm/s）降低且有显著降低的强烈趋势。
