摘要
目的:探讨髋臼唇的形态及在髋关节生物力学行为中的作用。方法:取成人髋关节标本60个,测量髋臼唇在距髋臼顶点前后30°、60°、90°、135°处的宽度和厚度,观察髋臼唇撕裂的位置,测量大小,测量由髋臼唇增加的髋臼腔的容积。结果:髋臼唇在距髋臼顶点前90°最宽(8.82±2.20)mm,在髋臼顶点处最厚(5.56±1.56)mm。髋臼唇撕裂的发生率为81.7%(49/60例),多发生在髋臼的前上象限(80%),撕裂的大小为(2.5±0.2)cm(0.5 ̄4.5cm),髋臼唇可使髋臼腔的容积增加33%。结论:髋臼唇是维持髋关节正常生物力学行为的重要组成部分,髋臼唇撕裂是引起髋部疼痛的原因之一。
Objective: To study the morphology of the acetabular labrum and the effects of it on the biomechanics of the hip joint. Methods: Sixty samples of hip were harvested for this study. The width and thickness of labrum were measured on nine positions: midsuperior, anterosuperior 30° ,60°, 90°, 135°and posterosuperior 30° ,60° ,90°, 135°. The positions and size of labral tears were observed and the increasing volume of coxal cavity was measured. Results: The labrum was the widest at the point of anterosuperior 90° (8.82±2.20) mm and the thickest at the point of midsuperior(5.56±1.56) mm. For hips, the rate of gross labral tears was about 81.7%, most of them (80%) located in the anterior superior quadrant. The average size of the tears expansion was about 2.5 cm (0.5~4.5 cm). The acetabular labrum could increase of acetabular volume about 33%. Conclusions: The acetabular labrum is an important element of physiological functions of acetabulum, while acetabular labral tear is a biomechanical cause of hip pain.
