Slipped capital femoral epiphysis (SCFE) is one of the most commonly missed diagnoses in children, typically occurring between ages 8 and 15. When the child cannot walk even with crutch support, the slip is classified as unstable — a distinct and more urgent presentation that drives a different management pathway.
Classification of SCFE is based on the stability of the physis. Inability to ambulate even with crutches defines the unstable category. This distinction is critical because it determines urgency, the need for immediate activity restriction, and which surgical approach is appropriate.
Immediate non-weight-bearing is the essential first step once the diagnosis is established. Surgical correction of the proximal femur is a core component of management — however, the specific procedure, timing, and technique involve clinical considerations beyond this overview. The complete protocol covers all of this.
SCFE usually occurs in those eight to 15 years of age and is one of the most commonly missed diagnoses in children.
Classification of SCFE is based on the stability of the physis.
If the patient is unable to ambulate even with crutches, it is considered unstable.
Once the diagnosis of SCFE is made, the patient should be placed on non-weight-bearing crutches or in a wheelchair and urgently referred to an orthopedic surgeon familiar with the treatment of SCFE.
Treatment goals are similar to those of stable SCFE with in situ fixation, but there is controversy as to the specifics of treatment, including timing of surgery, value of reduction, and manner of reduction.
The currently recommended approach is the modified Dunn procedure, which is a surgical hip dislocation that helps restore the alignment of the proximal femur to decrease the rate of femoroacetabular impingement.
