Good quality imaging is essential for diagnosis. A variety of surgical approaches have been advocated for the treatment of femoral head fracture. 2. Arteries traverse the length of the femoral neck and may be disrupted in a fracture of the femoral neck, contributing to the risk of osteonecrosis or nonunion. Extracapsular hip fractures (intertrochanteric and subtrochanteric) have a negligible risk of osteonecrosis. Intracapsular fractures may disrupt the blood supply to the femoral head, leading to … Combined fractures of the femoral head and neck are uncommon and associated with dislocations of the hip.

Involve the femoral neck between the edge of the femoral head and insertion of the capsule of the hip joint. The vascular supply to the femoral head is defined as follows (Fig. When a stress fracture occurs in the hip, it usually involves the femoral neck, the short section of bone that connects the head of the femur to the main shaft of the bone. In general, fractures of the femoral head are associated with dislocation of the hip.

On the basis of the clinical history and imaging studies, the diagnosis of a subchondral insufficiency fracture of the femoral head was made [1,2,3,4]. The ball-shaped head of the femur fits into a socket in the pelvis, called the acetabulum. The combination with an acetabular (posterior wall) fracture is also frequently seen. In both cases the damaged components were replaced with satisfactory results. 19-4): 1. Subchondral fracture of the femoral head has been reported to occur as an insufficiency fracture associated with poor bone quality or as a fatigue fracture in young military recruits. Around half of all hip fractures are intracapsular. This procedure is commonly recommended for cats, especially those who are at a healthy weight. In 90% of cases, the dislocations are posterior and in 10% anterior. The most commonly used classification system for femoral neck fractures is the Garden classification. As a result, the treating orthopaedic surgeon must understand not only the fracture pattern, but also patient-related fractures and the relevant operative exposures and reconstructive options to achieve the best functional outcome while minimizing complications. An unreduced dislocation is an emergency because it threatens the blood supply to the femoral head. Two cases of fracture of the ceramic head of a total hip replacement are presented. The patient underwent hemiarthroplasty in the right hip. Reduction a. c. The type V fractures can be further subclassified according to the location of the femoral head or neck fracture.

fracture of upper portion of femur (anywhere from femoral head to about 5 cm below lesser trochanter), typically resulting in groin and thigh pain; if fracture is displaced, affected extremity generally appears shortened (with hip positioned in external rotation and abduction) and patient is unable to bear weight 2,3 An FHO restores mobility to the hip by removing the head of the femur. Closed reduction is attempted first.

Intertrochanteric Hip Fractures: An intertrochanteric hip fracture occurs just below the femoral neck. Because these fractures involve the femoral head and neck, the blood supply to the fracture … They should be suspected.
