Q

Why are displaced intracapsular neck of femur fractures a major concern ?

A

The blood supply to the neck of the femur is retrograde passing from distal to proximal along the femoral neck to the femoral head. Predominantly through the medial circumflex femoral artery which lies directly on the intracapsular femoral neck. Therefore this fracture can disrupt the blood supply to the femoral head and avascular necrosis can occur.

Over time continuous wear or trauma to the joint causes local inflammation and stimulation of chrondrocytes to release degradative enzymes. These enzymes break down collagen and release proteoglycan and ultimately destroy articular cartilage. This leads to exposure of underlying subchondral bone causing subchondral sclerosis and the continuous remodelling can from subchondral cysts and osteophytes.
