What is an Avulsion Fracture of the ASIS?

An avulsion fracture of the ASIS occurs when a small chunk of bone attached to a tendon or ligament gets pulled away from the central part of the bone. The ASIS is a part of the pelvic bone and is a common site for such fractures, especially in active adolescents and young adults.

What Causes An Avulsion Fracture of the ASIS?

This injury typically occurs due to sudden, forceful muscle contractions during activities like sprinting, jumping, or kicking. These movements are common in sports such as soccer, football, track and field, and gymnastics. It’s particularly prevalent among adolescents during their growth spurts as their bones and muscles develop rapidly.


  • Sudden, sharp pain in the lower abdomen or groin area at the time of injury
  • Swelling and bruising in the affected area
  • Difficulty and discomfort while walking, running, or moving the leg
  • Tenderness at the site of the fracture


Early diagnosis is crucial for effective treatment. Our specialists will conduct a thorough physical examination and imaging tests like X-rays or MRI to confirm the presence and extent of the fracture.


Treatment for an avulsion fracture of the ASIS varies based on the severity of the injury.

Non-surgical Treatment

Most cases can be treated non-surgically and may include:

  • Rest and avoidance of activities that exacerbate pain
  • Ice application to reduce swelling
  • Over-the-counter pain relievers for discomfort
  • Physical therapy to restore range of motion and strengthen muscles

Surgical Treatment

Surgery may be required in cases where the bone fragment is significantly displaced. This procedure typically involves reattaching the fragment using screws or other fixation devices.

Recovery Time

Recovery time varies depending on the severity of the fracture and the treatment method:

Non-surgical recovery usually takes about 6 to 8 weeks. Post-surgical recovery might take longer, and the healing process can last up to 3 months.
Our team will guide you throughout your recovery through a rehabilitation program tailored to your specific needs, ensuring a safe and effective return to daily activities and sports.
