摘要目的 明确股骨近端解剖参数和髓腔形态与年龄、性别的关系,分析比较两种髓腔形态的界定方法.方法 随机抽取45例行全髋关节置换术患者术前所拍摄的患髋正、侧位X线片,测量股骨近端解剖参数,并分别运用Dorr分类法和Noble分类法对髓腔形态进行分析.结果 (1)男性股骨近端解剖参数与年龄无相关性.(2)女性股骨小转子中点下方10 cm处的髓腔内径、髓腔峡部处的髓腔内径、股骨髓腔峡部与股矩峡部比值与年龄呈正相关.(3)女性股骨小转子中点下方10cm内、外侧皮质厚度、皮质指数、股骨近端髓腔开口指数与年龄呈负相关.(4)根据Dorr分类法股骨髓腔形态分为A型13例(29%)、B型20例(44%)、C型12例(27%).根据Noble分类法股骨髓腔形态分为香槟酒瓶型4例(9%)、正常型34例(76%)、烟囱型7例(16%).结论 男性股骨髓腔形态不随年龄而发生变化,女性股骨髓腔形态随年龄增长而增宽.Dorr分类法中的C型包含了Noble分类法中的烟囱型和部分正常型.

abstractsObjective To identify the relationship of the femoral morphology with the sex and age, analyze and compare the two methods of defining the morphology of marrow cavity.Methods AP and lateral radiography of the hip joint was made in 45 patiens who accepted total hip arthroplasty.The anatomic parameters of the proximal femur were measured on those radiography.The femoral morphology was analyzed using Dorr criteria and Noble class respectively.Results (1)The anatomic parameters of the proximal femur were not correlated with the age in male.(2)The inner diameter of canal 10 em distal to the lesser trochanter, isthmus width and canal to calar isthmus rate were positively correlated with age in female.(3)The medial cortical and lateral cortical thickness 10 cm distal to the lesser trochanter,cortical index and canal-flare index were negatively correlated with age in female.(4)According to Dorr criteria,13 femora were classified as type A,20 as type B,and 12 as type C.According to Noble class,4 femora were classified as champagne type,34 as normal type,and 7 as stove pipe type.Conclusions The femoral morphology don't change with age in male.The width of femoral canal increase with age in female.Type C of Dorr criteria contains all of stove pipe type and a portion of normal type.
