✦ Synopsis

Biomechanic principles have important implications to film interpretation. Angulation of the femoral neck results in four different types of forces: compression on the medial side, tension on the lateral side, shear stress in the center, and torque forces at the neck-shaft angle. The body's response to these forces results in recognizable trabecular patterns which respond in a predictable manner to disease states. Surgical intervention in the form of hip replacement or fracture fixation must reflect these engineering considerations.

Twenty-five radiographic studies representative of the spectrum of trauma cases that might present to an emergency department were selected from actual cases presenting at Brooke Army Medical Center (BAMC) in San Antonio, Texas. The studies were then transmitted from a local television studio via sa
