Femoral head fractures are very rare injuries, almost always caused by hip dislocations.
The standard classification of femoral head fractures is that of Pipkin. The key criterion in the Pipkin classification is whether the femoral head is fracture above or below the fovea. A type 1 fracture is with the fracture...

Osteonecrosis (ON) of the femoral head causes the bone to deteriorate, buckle, and collapse. As the vasculature is reportedly uniform in the femoral head, one would expect uniform susceptibility to ON; however, collapse typically occurs in the anterior region. We asked whether regional variations in bone quantity and/or quality could...

Wear of highly cross-linked polyethylene is reportedly independent of head size. To confirm that observation we asked in our population whether head size related to wear with one type of electron beam highly cross-linked polyethylene.
We found no association between femoral head size and the linear wear rate, but observed...

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...

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;

We report seven children in whom traumatic haemarthrosis of the hip had produced lateral subluxation of the femoral head, which is different from the apparent displacement seen in Perthes' disease. In all seven cases, aspiration of the haemarthrosis allowed reduction of the femoral head, and follow-up for a mean of...

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...

Osteochondral defects of the femoral head are exceedingly rare, with limited treatment options. Restoration procedures for similar defects involving the knee and ankle have been well described. In this report, we present a young patient who had a symptomatic osteochondral defect of the femoral head develop secondary to trauma and...

Since cut-out still remains one of the major clinical challenges in the field of osteoporotic proximal femur fractures, remarkable developments have been made in improving treatment concepts. However, the mechanics of these complications have not been investigated yet. We hypothesize using the experimental data and a theoretical model that a...

Cementation for Femoral Head Osteonecrosis: A Preliminary Clinic Study. Clinical Orthopaedics & Related Research. 412:94-102, July 2003. Wood, Mark L. MD; McDowell, Cathy M. RN; Kelley, Scott S. MD Abstract: Treatment for femoral head osteonecrosis has been less successful in late stages of the disease, after progression to collapse. The current...

Hungerford, D. S. Early Diagnosis of Ischemic Necrosis of the Femoral Head. Johns Hopkins Medical Journal, 137 (1975), 270-275
Intraosseous pressure in the intertrochanteric region, and response to a five milliliter saline load injected intraosseously were measured in twenty-four hips in twenty patients with ischemic necrosis of the femoral head and...

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 of the femoral head in sickle-cell disease. Treatment of collapse by the injection of acrylic cement. Hernigou P, Bachir D, Galacteros F. Henri Mondor Hospital, Creteil, France. In ten patients with sickle-cell disease, we used a new technique of cement injection for the treatment of 16 painful hips with a radiographic...

Femoroacetabular impingement or FAI is a condition of too much friction in the hip joint. Basically, the ball (femoral head) and socket (acetabulum) rub abnormally creating damage to the hip joint. The damage can occur to the articular cartilage (smooth white surface of the ball or socket) or... Patient Provider

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...

A bone-conserving prosthetic solution, such as hip resurfacing arthroplasty, is desirable for patients with osteonecrosis (ON) of the femoral head because of their young age. However, many surgeons are reluctant to perform hip resurfacing for ON because of large femoral head defects. To ascertain whether this reluctance is warranted, we...

Conclusion Radiofrequency ablation is a newer treatment modality for osteoid osteoma that, being minimally invasive, offers comparable results to surgery with a significantly lower morbidity. To the best of our knowledge, treatment of osteoid osteoma in the foveal region of the femoral head with radiofrequency ablation has not been reported to...

We have observed damage to the labrum as a result of repetitive acetabular impingement in non-dysplastic hips, in which the femoral neck appears to abut against the acetabular labrum and a non-spherical femoral head to press against the labrum and adjacent cartilage. In both mechanisms anatomical variations of the proximal...

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...
