The relationship of anteroposterior, transepicondylar and posterior condylar axis of the femur: a Thai cadaveric study using digital measurement.

Objective: To study the normal relationship of the anteroposterior (AP), transepicondylar (TE) and posterior condylar (PC) axis of cadaveric femoral bones using digital technology and special computer program.

Material And Method: Digital image of distal femur of 100 cadaveric bones of both sides and both sexes were taken using a special stand and clamp to ensure the same view and same distance from bone to camera. All still images were transferred into a specially developed computer program, then reference points were located by two observers, and were done twice at one week interval.
