A patient has a fracture through the neck of the femur. Which complication is most directly related to interruption of blood supply to the femoral head?
Correct answer: A. Avascular necrosis
- A. Avascular necrosis
- B. Scoliosis
- C. Muscle hypertrophy
- D. Tendon shortening
Explanation
Avascular necrosis occurs when inadequate blood supply causes bone tissue to die, and it is a recognised concern after some femoral neck fractures. Scoliosis affects spinal alignment and does not result directly from this vascular injury.

About Skeletal and Muscular Systems
The skeletal and muscular systems include bone structure, joints, cartilage, the axial and appendicular skeleton, and the roles of ligaments and tendons. They also cover skeletal muscle organization, the sliding filament mechanism, neuromuscular contraction, and common differences between voluntary skeletal muscle, cardiac muscle and smooth muscle.
