Avulsion Fracture
Avulsion Fracture
A break in a bone where a tendon or ligament pulls a piece of bone away.
Apophyseal Injury
Apophyseal Injury
A break in the secondary ossification center of a bone, occurring at the growth plate.

Study Notes
Apophyseal Injuries (Avulsion Fractures)
- Common in adolescents due to stronger tendons compared to developing secondary ossification centres.
- Occur specifically in the unfused skeleton.
- Other avulsion fractures happen in children and adults, but those in the table are in secondary ossification centres around the pelvis.
- Lesser trochanter avulsion in adults suggests a possible metastasis, not a musculoskeletal injury.
Apophyseal Injury Locations and Associated Muscles
- ASIS (Anterior Superior Iliac Spine): Sartorius muscle
- AIIS (Anterior Inferior Iliac Spine): Rectus femoris (straight head)
- Pubic ramus: Adductors and gracilis muscles
- Lesser trochanter: Iliopsoas muscle
- Ischial tuberosity: Hamstring muscles
