APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Avascular necrosis is a painful bone condition that gets worse over time and can affect your mobility. It occurs when something cuts off blood flow to one of your bones. Causes include broken bones, dislocated hips, radiation therapy and alcohol misuse.

Detailed explanation-2: -Purpose: Traumatic hip dislocation can be isolated or associated with acetabular fracture. Both injuries require emergency reduction of the dislocated hip. Avascular necrosis of the femoral head (AVN) is a potential complication that accompanies these severe injuries.

Detailed explanation-3: -Avascular necrosis (AVN) of the femoral head is a relatively uncommon complication following an extracapsular hip fracture. Although it can occur following fixation of unstable 3-part or 4-part intertrochanteric fractures with significant posteromedial and posterolateral comminution, it remains a rare complication.

Detailed explanation-4: -Injury. Fracture. Damage to blood vessels. Long-term use of medicines, such as corticosteroids. Excessive, long-term use of alcohol. Specific chronic medical conditions.
