Fractured Femur, Posterior View

Description

Posterior anatomy of the male thigh frames the femur from the proximal epiphysis to the knee, with the fracture emphasized along the proximal posterior cortex at the intertrochanteric crest between the greater and lesser trochanters. Inferior to the trochanteric region, the linea aspera tracks distally along the posterior shaft, flaring into the medial and lateral supracondylar lines as the bone widens toward the distal metaphysis. At the knee, the posterior distal femur forms the medial and lateral condyles separated by the intercondylar fossa, aligning with the tibial plateau and the fibular head laterally. Soft tissues are rendered semi-transparently so the osseous landmarks remain readable. Intertrochanteric fracture patterns matter because they sit outside the femoral head and neck capsule, so femoral head osteonecrosis is less common than with intracapsular femoral neck fractures, yet displacement can be pronounced under the pull of gluteus medius and minimus on the greater trochanter and iliopsoas on the lesser trochanter. Reduction and fixation planning depends on appreciating the posterior cortical buttress at the intertrochanteric crest and the relationship of the proximal fragment to the shaft, since posterior comminution increases the likelihood of varus collapse after a sliding hip screw or cephalomedullary nail. Expect limb shortening and external rotation clinically. It is a pattern trauma teams see weekly. Orthopedic educators can drop this posterior view into lectures on hip fracture classification, operative fixation strategy, and postoperative radiographic assessment, because the trochanteric contours and distal femoral references support side-to-side orientation. Medical publishers will find it suited to atlas plates that compare intracapsular versus extracapsular proximal femur fractures, and to case-based modules covering perioperative complications such as blood loss from cancellous bone and malreduction.
