What is an avulsion fracture of the anterior inferior iliac spine?

Avulsion fractures of the anterior inferior iliac spine are uncommon and such injuries are caused by the sudden forceful contraction of the straight head of rectus femoris muscle while the hip is hyperextended and the knee is flexed.

Which muscle causes most common avulsion injury?

Avulsion fractures of the ischial tuberosity are the most common. They tend to occur during sprinting and are due to the sudden, powerful contraction of the hamstring muscles when the hip is flexed and the knee extended (Fig. 22.55A).

What is Apophyseal avulsion?

Apophyseal avulsion fractures of the pelvis are injuries that typically occur in adolescent athletes [1]. At this age the secondary ossification at the apophyses coincides with the hormonally induced strengthening of the muscles [2].

Where is the anterior inferior iliac spine located?

hip bone
The anterior inferior iliac spine (AIIS) is a bony eminence on the anterior border of the hip bone, or, more precisely, the wing of the ilium.

What muscles attach to the anterior inferior iliac spine?

The rectus femoris muscle of the quadriceps group of thigh muscles attaches to the anterior inferior iliac spine, as well as the iliofemoral ligament.

What is the difference between an avulsion fracture and a fracture?

A fracture is a break or crack in a bone that often results from an injury. With an avulsion fracture, an injury to the bone occurs near where the bone attaches to a tendon or ligament. When the fracture happens, the tendon or ligament pulls away, and a small piece of bone pulls away with it.

Can you make an avulsion fracture worse?

Your avulsion fracture can get worse if you don’t follow your healthcare provider’s advice.
