Lesser Trochanter Of The Femur, Posterior View

Description

Lesser trochanter anatomy dominates the proximal femur in this posterior perspective, appearing as a conical bony eminence on the posteromedial aspect just inferior to the femoral neck. From this angle, the lesser trochanter sits medial to the greater trochanter and inferior to the intertrochanteric crest, with the posterior shaft extending distally toward the linea aspera. Subtle contour changes around the trochanteric fossa and the posterior margin of the neck help orient the viewer to the hip’s bony architecture. Orientation is unambiguous. Iliopsoas inserts on the lesser trochanter, so this landmark matters whenever hip flexion mechanics or anterior hip pain are on the differential. Avulsion fracture of the lesser trochanter in adolescents can follow forceful contraction, while an isolated lesser trochanter fracture in an adult without major trauma raises concern for pathologic fracture from metastatic disease. Posterior viewing also supports operative planning and teaching for proximal femur fixation, where understanding the posteromedial cortical buttress and the relationship of the lesser trochanter to the calcar femorale informs implant position and reduction goals. Use this illustration in gross anatomy and musculoskeletal medicine courses to anchor discussions of proximal femoral landmarks, muscle insertions, and intertrochanteric fracture patterns. It also suits orthopedic texts, radiology teaching files (correlating with AP/lateral hip radiographs and CT), and patient education material explaining why a “small bump” on the femur can matter in hip pain or fracture assessment.
