Structure and Location of the Female Femur

Description

Highlighted femora (thighbones) are shown in situ with the bony pelvis, with each femoral head seated medially and superiorly within the acetabulum formed by the ilium, ischium, and pubis, and the sacrum closing the pelvic ring posteriorly. Inferior to the head, the femoral neck leads laterally to the greater trochanter, while the shaft descends distally toward the knee where the medial and lateral condyles align with the tibial plateau, and the patella sits anterior to the distal femur. Spatial relationships are clear: proximal femur at the hip joint, distal femur at the knee, and bilateral symmetry across the midline. Key landmarks stand out. This pelvis-to-knee context matters when you are teaching why hip pain can be articular, periarticular, or referred, because the ball-and-socket articulation at the acetabulum concentrates load through the femoral head and neck before it is transmitted along the diaphysis to the condyles. Femoral neck fractures, common in osteoporotic older women, occur at a site where retinacular branches of the medial femoral circumflex artery are vulnerable, so head viability and the choice between internal fixation and arthroplasty hinge on understanding this anatomy. The same proximal geometry frames discussions of developmental dysplasia of the hip and femoroacetabular impingement, where coverage of the femoral head by the acetabulum and the head-neck offset affect range of motion and chondrolabral wear. Coursework in gross anatomy, orthopaedics, radiographic anatomy, and physical therapy can use this graphic to orient learners to proximal and distal femur landmarks before moving to AP pelvis or hip radiographs and preoperative templating for total hip arthroplasty. Medical publishers will also find it suitable for patient-facing explanations of hip fracture and postoperative rehabilitation, where clear proximal versus distal reference points prevent confusion.
