E. Osteosarcoma

Answer :

Final answer:

A) Avascular necrosis is a complication of a femoral neck fracture due to disrupted blood supply leading to bone and cartilage death.

Explanation:

A complication of a femoral neck fracture is avascular necrosis. This condition occurs when there is a disruption of the blood supply to the femoral neck or head, leading to necrosis of these areas and resulting in the death of bone and cartilage.

Apart from that, femoral fractures usually require surgical treatment and post-surgery, the patient often needs mobility assistance for a prolonged period. These fractures are associated with a substantial increase in health care costs and are also linked with higher rates of morbidity and mortality. Complications such as deep vein thrombosis, pneumonia, and pressure sores can occur due to prolonged bed rest after hip fracture surgery.
