Abstract:
Objective 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.
