Femur Showing The Intertrochanter Line, Medial View

Description

Femur anatomy is presented from a medial perspective, centering the intertrochanteric line where the femoral neck transitions into the proximal shaft. The femoral head sits superior and medial, with the fovea capitis visible on its articular surface, while the neck angles inferolaterally toward the trochanteric region. Along the anteromedial aspect of the proximal femur, the intertrochanteric line runs obliquely between the base of the greater trochanter laterally and the lesser trochanter posteromedially, forming a palpable ridge at the junction of neck and shaft. Distally, the smooth medial surface of the diaphysis leads toward the medial supracondylar area, establishing the long-axis orientation of the bone in anatomical position. The intertrochanteric line matters because it marks the attachment of the fibrous capsule of the hip joint and the origin region for parts of the iliofemoral ligament, so its exact location helps clarify why intracapsular femoral neck fractures differ clinically from extracapsular intertrochanteric fractures in bleeding risk and femoral head viability. Landmark precision also supports surgical planning around the anterior hip capsule and the proximal femur, where implant positioning and exposure can be described relative to the neck-shaft junction rather than relying on less consistent soft-tissue cues. A fixed medial viewpoint keeps the neck contour and proximal shaft alignment easy to judge. It reduces ambiguity between the intertrochanteric line (anterior) and the intertrochanteric crest (posterior). Orthopedic teaching files, hip arthroplasty course materials, and fracture classification diagrams (AO/OTA proximal femur patterns) commonly need a medial reference image to annotate the intertrochanteric region and capsule attachment sites. Medical publishers can also pair this illustration with radiographic or CT figures to help readers translate a 3D bony ridge into expected contours on anteroposterior hip imaging.
