【摘要】 目的 :探讨股骨头凹类型与股骨头缺血性坏死的关系。方法 :对 2 50例正常成人股骨头凹及其滋养孔数目、大小进行了观测。结果 :按股骨头凹形态分为五型 ,按其深度分为三型。股骨头凹滋养孔以单孔最多 ( 37.2 % ) ,无孔次之 ( 2 8% ) ,3孔以上较少。滋养孔大小以中孔多见 ( 82 .95% )。浅平型和凸型股骨头凹 X线片可能不显影 ,出现无孔的机率明显高于凹型 ( P<0 .0 1)。结论 :浅平型或凸型股骨头凹发生股骨头缺血性坏死的机率可能高于凹型更多还原

【Abstract】 Objective:To investigate the relationship between the shapes of femoral head fovea and ischemic necrosis of the femoral head. Methods:The shape of the femoral head fovea the size and numbers of their nutrient foramina were observed in 250 normal adult femur. Results: The fovea of the femoral head was classified into 5 types and 3 types according to the shape and depth respectively. It was found that the femoral head fovea with single nutrient formaen was in majority(37.2%), without any nutrient formane was the second (28%) and with more than 3 nutrient foramina was in minoirty. The nutrient foramina were mostly in middle size (82.95%). The femoral head fovea in shallow flat shape or in convex shape were not seen in X Ray films. The rate of this 2 femoral head fovea was significantly higher than concave ones(P<0.01). Conclusion: It is suggested that the rate of ischemic necrosis of the femoral head in shallow flated or convex shaped is probably much higher than the concave shaped ones.更多还原
