A Study on the Neck Shaft Angle of Femur In-100 Macerated Bones

Neck of the femur is a mystery in terms of its position, blood supply, direction and function. It doesn't lie in the same plane like that of the femoral shaft and its condyle. The neck sustains an angle with the shaft and lies anterior to it in the coronal plane- referred conventionally as femoral ante version. In rare occasion neck lies posterior to the shaft calls as femoral retroversion.

Exclusive of any deformity or fracture are studied with 100 cadaveric adult femurs with the help of Martins Dioptrograph. The angle between the long axis of the neck and the long axis of the shaft were evaluated. Various workers of the country have evaluated this aspect and globally the literatures covering the subject are plenty and the prosthesis commonly used for hemi and total hip arthoplasty are foreign manufactured. Considering the neck shaft angle, when used in our population it presents some pitfall like restriction of squatting position, chronic hip Pain etc. Hopefully this study will throw some light and guidelines for the manufacturer of prosthesis in this century keeping these facts in mind.
