The Lesser Trochanter Of The Femur In Posterior View

Description

Rotating into a posterior view of the proximal femur, the animation centers on the lesser trochanter, a conical bony prominence projecting from the posteromedial junction of the femoral neck and shaft. The intertrochanteric crest spans laterally between the greater and lesser trochanters, while the trochanteric fossa sits on the medial surface of the greater trochanter. As the femur turns, the line of the linea aspera becomes apparent on the posterior shaft, reinforcing the medial to lateral relationships around the hip joint. Bony landmarks stay in sharp relief. For teaching proximal femoral anatomy, the lesser trochanter matters because it marks the insertion of the iliopsoas tendon (psoas major and iliacus), the prime hip flexor, and it sits close to the region where femoral neck fractures and intertrochanteric fractures are classified and described. The posterior sequence clarifies why the lesser trochanter appears displaced medially and proximally in unstable intertrochanteric fracture patterns, and why an avulsion fragment in an adolescent can indicate a traction injury of the iliopsoas apophysis. Motion helps resolve the common confusion between anterior neck contours and the true posteromedial projection of the lesser trochanter, a detail that influences radiographic interpretation on AP pelvis and frog-leg lateral views. Use this clip in gross anatomy labs, orthopedic trauma lectures, and radiology teaching files where you need quick orientation to posterior proximal femoral landmarks before discussing fixation strategies and fracture lines. It also supports figure development for anatomy atlases and surgical approach overviews for the posterolateral hip. Anatomical accuracy verified by SciePro's Medical Advisory Board.
