摘要
目的对正常人骨盆体位变动下相应髋臼角度的三维监测观察,为临床上髋关节假体置入的角度判定提供解剖学参考依据。方法对60名受试者于不同体位下进行骨盆侧位X线摄片并进行前倾角监测。摄片体位包括自然站立位、自然仰卧位及屈髋抱膝仰卧位。结果在自然站立位、自然仰卧位及屈髋抱膝仰卧位的前倾角分别为——青年组:64.2°±3.33°,60.6°±3.53°,45.4°±5.69°;老年组:68.0°±3.33°,67.0°±3.92°,55.0°±3.34°。站立位较自然卧位骨盆前倾角差值均数为3.56°(青年组)和3.60°(老年组)。站立位较屈髋抱膝仰卧位骨盆前倾角均数差值为18.8°(青年组),12.1°(老年组)。结论屈髋抱膝仰卧位较站立位时骨盆前倾角变化显著,使得髋臼窝开口与躯干水平面及矢状面间角度改变较大,会影响关节置换术臼杯置入角度的准确性,因此在临床上应予以重视。
Objective To observe the motion range of the human pelvis in different position and evaluate the change of acetabular orientation during total hip replacement. Methods The X-ray photographs of lateral-position of pelvis in different positions were taken and the anteversion angles of pelvis were measured on the X-ray photograph. The positions included standing position, dorsal position and hip-flexion dorsal position. Results The anteversion angle of pelvis on the X-ray photograph of standing position, dorsal position and hip-flexion dorsal position were respectively 64.2°±3.33°, 60.6°±3.53°, 45.4°±5.69° （young group） and 68.0°±3.33°, 67.0°±3.92°, 55.0°±3.34° （elder group）. Differential value mean of anteversion angle between standing position and dorsal position were 3.56°±1.41° in young group and 3.60°±1.34° in elder group. The mean differential value of standing position and hip-flexion dorsal position were 18.8°±4.74° in young group and 12.1°±2.48° in elder group. Conclusion The change of the anteversion angle of pelvis is very significant between standing position and hip-flexion dorsal position. It would lead to significantly change of the acetabular orientation. Therefore, it must be abended during total hip replacement.
