What is anterior inferior iliac spine?

The anterior inferior iliac spine (AIIS) is a prominent bony projection located on the front of the hip bone (ilium). It serves as an important attachment point for several muscles, including the rectus femoris muscle of the quadriceps muscle group.

The AIIS is involved in various movements of the hip and thigh, such as hip flexion and rotation. It plays a crucial role in stabilizing the hip joint during activities such as walking, running, and jumping.

Injuries to the AIIS can occur due to trauma, overuse, or muscle imbalances. These injuries may present as pain in the front of the hip and may impact a person's ability to perform certain movements or activities.

Treatment for AIIS injuries typically involves rest, physical therapy, and, in some cases, surgical intervention. Rehabilitation exercises targeting the muscles that attach to the AIIS are often prescribed to help improve strength and stability in the hip joint.
