Your child has been diagnosed with a condition called slipped capital femoral epiphysis (SCFE). This means that the femoral head (“ball” at the top of the thighbone) has slipped slightly off the thighbone. (It may help to picture a scoop of ice cream slipping off of a cone.) This problem can be very serious if not treated. Your child will likely be referred to an orthopedist, a doctor specializing in treating bone and joint problems, for evaluation and treatment.
In some cases, SCFE occurs suddenly due to an injury or trauma. In other cases, it develops slowly over time due to an underlying problem. In many cases, the cause of SCFE is not known. Risk factors include:
Being between ages 8 and 15
Being a boy (more boys than girls have this condition)
Being African American
Having a problem with the thyroid gland
Taking certain medications (such as oral steroids or growth hormones)
Symptoms of SCFE include:
Walking with a limp
Pain in the hip that may get worse with activity
Complaints that the hip feels like it’s “giving way”
Walking with the leg turned outward
Pain in the knee or thigh (in severe cases, the child may not be ablt to bear weight)
SCFE is often diagnosed by examining the child and watching him or her walk. An imaging test such as an X-ray is done to confirm the diagnosis. In some cases, additional imaging studies such as an MRI may be needed. Other tests may be done to check for an underlying problem (such as a thyroid problem) that could cause the SCFE.
Treating SCFE is considered urgent because further slipping could damage the hip joint. To prevent further slipping, the child may be admitted to the hospital right away for surgery or instructed to use crutches and not put any weight on the leg until the SCFE can be repaired. Surgery is often done within a day or two of diagnosis. During the surgery, the surgeon puts a steel screw through the thigh bone into the femoral head. This screw holds the femoral head firmly in place.
After surgery to fix a SCFE, the child will need to walk with crutches for 6 to 8 weeks.
The child may be referred to a physical therapist for treatment during recovery.
Follow-up is essential every 3 to 4 months for the next several years to recheck the treated hip.
In a child with SCFE in one hip, the normal hip may be at increased risk of slipping. This is especially true if an underlying problem led to the SCFE, or if the child is younger than age 10. In these cases, the surgeon may recommend pinning the normal hip along with the slipped hip. This prevents problems in the future.
With treatment, SCFE often has a good outcome, especially if treated early. Your child’s doctor can tell you more.
Even after treatment, a child with SCFE is more likely to have arthritis in that hip as an adult.
In rare cases, even with treatment, the hip joint can still have problems. This is more likely if the growth plate (a soft part of a long bone that allows the bone to grow as the child grows) was injured by the slip. Disruption of the blood supply to the femoral head during the slip may also lead to problems. Problems are more likely with severe SCFE. Catching these problems early is one of the reasons why it is essential to continue to follow up with the surgeon as your child grows.
