Slipped capital femoral epiphysis, or SCFE, is a disorder of the hip joint. This condition takes place when the ball at the end of the thigh bone slips off the thigh bone at the growth plate. This is caused by a weakness in the growth plate. It is not fully understood why this condition occurs, but it commonly develops after periods of rapid growth after the onset of puberty. Slipped capital femoral epiphysis is the most common hip disorder that occurs in adolescent children.
SCFE is related to adolescent growth spurts. Some children’s growth plates weaken while they are growing and broadening. The broadening of the growth plate (which is not as strong as bone) as well as the shape of the thigh bone and hip socket can lead to a slipped capital femoral epiphysis.
SCFE is more common in males than in females and typically occurs in children ages 10-16. Children who are overweight, have hormonal abnormalities, and take steroid medication are at a higher risk for a SCFE.

A slipped capital femoral epiphysis (SCFE) is diagnosed based on history, physical exam and x-ray. If your child has SCFE, a physical exam will produce pain and limited range of motion. Your child will most likely want to keep his or her hip rotated outward (knee away from the body), and it will be difficult for the doctor to rotate the leg in (knee towards the body).
As you’re looking at your child’s x-ray, SCFE is apparent on x-ray as the head of the femur (thigh bone) will appear to be slipping off the femur bone. It looks like a scoop of ice cream melting off the cone.
If a SCFE is hard to determine based on x-ray, your doctor at Children’s Colorado may order an MRI for further evaluation. In some severe cases a CT scan (or CAT scan) may be necessary to better evaluate the bony deformity.
In our Hip Program at Children’s Hospital Colorado, we have orthopedic doctors who are specialized in pediatric hips. We use x-rays, CT scans and MRI to determine a diagnosis. The hospital has very advanced, state-of-the-art MRI technique that provides the doctor with a more accurate measurement of the health of the cartilage in the hip.
X-rays are taken in our clinic during your appointment with your child’s doctor. CT and MRI scans are performed in the radiology department. The CT scans take approximately 15 minutes to complete. The MRI in patients older than 6 years old is typically not a sedated procedure and lasts approximately 45 minutes to one hour. The MRI sometimes requires IV placement of contrast before the scan is done. If your child does need an MRI, feel free to bring a movie or music and have him or her wear comfy clothes.
Early diagnosis of slipped capital femoral epiphysis (SCFE) is important to provide the best chance of preventing further slipping and damage to the blood supply of the femoral head. Once a SCFE is diagnosed your child should not bear weight on the affected leg. All children who are diagnosed with SCFE require a surgical intervention to prevent further damage of the hip. The SCFE will be treated by either pinning the head of the femur where it is to the femur bone (in-situ pinning) or through an open surgery where the ball (femoral head) is reduced back to the correct position on the thigh bone and pinned in place.
The hip specialists at Children’s Colorado will work with you to decide which surgery is best for your child. Due to the high risk of a SCFE occurring on the other hip, prophylactic pinning of the other hip may be recommended depending on your child’s age. Later in life a surgical intervention may be necessary if there is femoro acetabular impingement as a result of the change in shape of the ball and hip socket.
By working together as a team, our orthopedic hip specialists are able to develop a comprehensive approach to both patient diagnosis and individualized treatment plans. Specialists from our Hip Program offer a broad spectrum of options for our patients and extend to include experts in the fields of rehabilitation, physical therapy, rheumatology, anesthesiology, and pain.
With a sole focus on hip disease in young patients, our Hip Program is nationally recognized for excellence in hip surgeries, and our doctors educate healthcare providers around the nation on hip diseases and surgery. Our goal is to provide our patients with options for pain control, function improvement, and preservation of the hip joint.
