Femoral Neck Anatomy

Fractures of the neck of femur are very common injuries which mainly occur in elderly females with osteoporotic bones. Obq11233 a 48 year old active female runner underwent percutaneous screw fixation of a minimally displaced femoral neck fracture six months ago.

Femoral neck anatomy. Femoral neck fractures are a subset of proximal femoral fractures. Abstract paediatric femoral neck fractures are uncommon injuries and are usually caused by high energy trauma. Surgical options can vary based on age delbet classification and displacement of the fracture.

At the ends of the femur are areas of compact bone which is solid and does not contain marrow. Inside the body of the femur is the medullary cavity which contains bone marrow. The femoral aspect of the hip is made up of the femoral head with its articular cartilage and the femoral neck which connects the head to the shaft in the region of the lesser and greater.

Surrounding the compact bone is spongy bone which has lots of small cavities dispersed throughout it. A fractured neck of femur is classified as either intracapsular or extracapsular. The femoral neck is the weakest part of the femur.

Since disruption of blood supply to the femoral head is dependent on the type of fracture and causes significant morbidity diagnosis and classification of these fractures is important. The neck and head of the femur contain spongy bone. The classical clinical finding is that of an externally rotated shortened leg.

The hip joint capsule inserts along the intertrochanteric line. The femur neck femoral neck or neck of the femur is a flattened pyramidal process of bone connecting the femoral head with the femoral shaft and forming with the latter a wide angle opening medialward. Low energy trauma can result in pathologic neck fractures and stress fractures of the neck due to repetitive activity.

There were no immediate post operative complications and she was progressed to full weight bearing three months after surgical fixation. A fracture distal to this line is therefore extracapsular whereas a fracture proximal to this is intracapsular. The femoral neck the femoral neck usually sits at a 120 135 degree angle with some variation.

A fracture of this area is known as a hip fracture and happens during aging.
