Summary
The pelvis is an osseous ring formed by sacrum and paired innominate bones, the latter composed of the ilium, ischium, and pubis. In terms of stability, the pelvic ring consists of two separate arches: the posterior and anterior arches. The hip joint is an articulation composed of the acetabulum and the femoral head. The femoral neck links the femoral head to the proximal femoral shaft at the intertrochanteric region. Femoral head fractures usually occur following hip dislocations. Intracapsular femoral neck fractures include subcapital, transcervical, and basicervical fractures. Extracapsular femoral neck fractures include greater trochanter fractures, lesser trochanter fractures and intertrochanteric fractures. Subtrochanteric femoral fractures are common in the elderly, but subtrochanteric and femoral shaft fractures are common in young patients, and usually occur following a high-energy force. Radiographs of the pelvis are the first imaging tests to obtain in patients subjected to high-velocity pelvic trauma or suspected proximal femur fracture.
