Anatomical Considerations:
- osseous anatomy of proximal femur dictates where internal fixation device should be placed for maximum purchase in femoral head;
- maximum bone density is found in the area where compression & tension trabeculae coalesce in the center of the head;

Background Avascular necrosis (AVN) of the femoral head is a pathologic process resulting from interruption of blood supply to bone. AVN of the hip is poorly understood but is the final common pathway of traumatic or nontraumatic factors that compromise the already precarious circulation of the femoral head. Femoral head ischemia...

The Old Begets the New: Trochanteric Nail Insertion for Femoral Shaft Fractures, Revisited
Purpose : Intramedullary (IM) nailing of femoral shaft fractures through a trochanteric starting point with the patient in a lateral decubitus position was popularized in the 1940s by G. Kuntscher. Large diameter nails (without locks) were used to obtain an interference...

MD Abstract: Treatment for femoral head osteonecrosis has been less successful in late stages of the disease, after progression to collapse. The current...

Osteonecrosis of the Femoral Head from Medscape General Medicine™ Posted 05/07/2003 Brett Levine, MS, MD, William Jaffe, MD Introduction Osteonecrosis of the femoral head (ONFH) is the end point of a variety of disease processes resulting in decreased blood flow and, ultimately, cellular death within the femoral head.[1] This debilitating disease typically affects younger patients...

Avascular necrosis has been documented following Disseminated Intravascular Coagulation 2 . We are presenting such a case of bilateral avascular necrosis of femoral heads, which interestingly was followed by the spontaneous presentation of the patient's sister with a unilateral avascular necrosis of the femoral head. Both sisters presented with symptoms...

Hip fractures are classified as intracapsular, which includes femoral head and neck fractures, or extracapsular, which includes trochanteric, intertrochanteric, and subtrochanteric fractures. The location of the fracture and the amount of angulation and comminution play integral roles in the overall morbidity of the patient, as does the preexisting physical condition...

Author: George D Harris, MD, MS 2004
Legg-Calvé-Perthes disease (LCPD) is avascular necrosis of the proximal femoral head resulting from compromise of the tenuous blood supply to this area. LCPD usually occurs in children aged 4-10 years. The disease has an insidious onset and may occur after an injury to the...

OTA paper 2004: We investigated whether the presence of head injury is associated with accelerated bone healing in patients with femoral shaft fractures.

The hips, along with the knees, are the large weight-bearing joints that allow you to walk, sit, bend and turn. As the body's most flexible, free-moving joint, a healthy hip can move back and forth, swing from side to side and perform twisting motions. This remarkable range is possible because...
