![]() ![]() Treatment for femoral neck fractures usually requires some type of surgical intervention to ensure mobility and function can be maintained. Motor vehicle accidents are also a common way to fracture the femoral neck in either population. These falls usually require the foot to be stuck or locked into place with a forcible rotation applied to the hip. However, in the older population these fractures tend to occur during falls. This usually happens when the hip joint is loaded and is forced to abduct (leg moves away from the body). In the younger or more “high energy” population it is more common to have fractures present in this area due to excessive impact and force generation. There are a few different mechanisms of injury for femoral neck fractures. Therefore, if you suspect an injury to the femoral neck you should contact a specialist immediately for evaluation and continued care. One area of concern is that the major artery which supplies blood and nutrients to this area passes directly through the hip joint and an injury here can directly affect blood flow to the upper portion of the femur. ![]() This means that there is increased force development which can lead to overuse and acute traumatic injuries. Many muscles, ligaments, and tendons originate or insert in this area to allow increased mobility and range of motion for activities of daily living. Unfortunately, this causes the bone to be weaker and more prone to fractures. The bone in this location thins and changes shape to allow articulation with the hip joint. Fractures tend to form in this area due to the weakened structure of the femur. The formal head forms the junction of the acetabulum (also known as the hip joint). The femoral neck is located at the top of the femur, where it thins to develop the femoral head. The femur is also known as the "Thigh Bone". They occur in the femur, which is the longest and strongest bone in the body. Osteoporosis can be a contributing factor.įemoral Neck Fracture of Femur Anatomy of A Femoral Neck Fractureįemoral neck fractures come in many different shapes and sizes. These injuries tend to have a higher prevalence in the geriatric population, emergency medicine, and younger patients who participate in high-risk impact sports. They are rare overall, but in certain populations it can be a commonplace injury. In general, stage I and II are stable fractures and can be treated with internal fixation (head-preservation), and stage III and IV are unstable fractures and hence treated with arthroplasty (either hemi- or total arthroplasty) 3.Femoral neck fractures are often called Hip Fractures. Garden stage IV: complete fracture, completely displacedįemoral head aligned normally in the acetabulum and its medial trabeculae are in line with the pelvic trabeculae Garden stage III: complete fracture, incompletely displacedįemoral head tilts into a varus position causing its medial trabeculae to be out of line with the pelvic trabeculae Medial group of femoral neck trabeculae may demonstrate a greenstick fracture Garden stage I: undisplaced incomplete, including valgus impacted fractures Garden described particular femoral neck and acetabular trabeculae patterns which can assist in recognizing differences within this classification system 2. It is simple and predicts the development of osteonecrosis 1,2. ![]() The Garden classification of subcapital femoral neck fractures is the most widely used. ![]()
