Pelvic Avulsion Fractures In Children


  • A pelvic avulsion fracture (FRAK-chur) occurs when a piece of pelvic (hip) bone breaks and tears away. This happens when a tendon or ligament connected to the hip bone tightens so hard it pulls off part of the bone. Pelvic avulsion fractures are usually caused by playing sports that need quick running starts and quick stopping. Football players, hurdlers, sprinters, long-jumpers, gymnasts, and cheerleaders are more prone to have a pelvic avulsion fracture.
  • Your child may have a sudden pain or feel a pop in his hip or groin. The groin is the area where his abdomen (belly) meets his upper leg. Your child may also have trouble moving his hip and leg or trouble sitting or walking.
  • Tests to diagnose a pelvic avulsion fracture may include hip x-rays or a bone scan. A magnetic resonance imaging (MRI) or a computerized tomography (CT) scan may also be done. Treatment will depend on how severe your child's fracture is. Sometimes only rest and exercises are needed to heal the fracture. Surgery may be needed for fractures that are severe or do not heal with other treatments. Ask your caregiver for more information about these tests and treatment.


You have the right to help plan your child's care. Learn about your child's health condition and how it may be treated. Discuss treatment options with your child's caregivers to decide what care you want for your child.


An injury to your child's hips may cause other problems. The bones may not go back to how they were before the injury. The bones may also not fit back together on their own and may need surgery. The muscles around the fracture may be affected and may cause weakness. Your child may have problems with his leg or foot if a nerve is blocked by the fracture. Early diagnosis of how bad the fracture is and follow-up are very important. Call your child's caregiver if you have concerns about your child's fracture, medicines, or care.


Informed consent

is a legal document that explains the tests, treatments, or procedures that your child may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your child's medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done to your child. Make sure all of your questions are answered.

Emotional support:

Stay with your child for comfort and support as often as possible while he is in the hospital. Ask another family member or someone close to the family to stay with your child when you cannot be there. Bring items from home that will comfort your child, such as a favorite blanket or toy.


  • Pain medicine: Your child may need medicine to take away or decrease pain. Know how often your child should get the medicine and how much. Watch for signs of pain in your child. Tell caregivers if his pain continues or gets worse. To prevent falls, stay with your child to help him get out of bed.


Your child may have one or more of the following:

  • Bone scan: During this test, pictures are taken of your child's bones. Your child is given a small, safe amount of radioactive dye in an IV. Caregivers can look at the pictures for broken bones, infection, or cancer in the bones.
  • Computerized tomography scan: This is also called a CT or CAT scan. This is a type of x-ray that uses computers to take pictures of your child's hip area. Your child may be given a dye before the pictures are taken to help caregivers see the pictures better. People who are allergic to iodine or shellfish (lobster, crab, or shrimp) may be allergic to some dyes. Tell your child's caregiver if your child is allergic to shellfish or has other allergies or medical conditions.
  • Magnetic resonance imaging scan: This is also called an MRI. The test uses magnetic waves to take pictures of your child's hips.
  • X-rays: Your child may need x-rays of his pelvis to check for broken bones or other problems in his hip. Several pictures may be taken of the bones in your child's hips.

Physical therapy:

A physical therapist helps your child with special exercises. These exercises help make your child's bones and muscles stronger.

Treatment options:

A pelvic avulsion fracture that is severe or does not heal with other treatments may need surgery. Surgery may be done by putting the bones together using metal pins, screws, or plates. This helps return the bones to their normal position.
