Basics
Description
- Slipped capital femoral epiphysis (SCFE) is displacement of the epiphysis of the head of the femur.
Epidemiology
- Males > females (3:2)
- Left hip twice as often as right, 25% bilateral
- Associated with obesity, increased height, genital underdevelopment, pituitary tumors, growth hormone therapy
Incidence
- 1–5 per 100,000
- Age of onset: boys, 14–16 years; girls, 11–13 years (essentially, premenarche)
Risk Factors
Genetics
5% of children affected have a parent with SCFE.
Pathophysiology
- Unclear: abnormal stress on normal physeal plate versus a process that weakens the plate
- The femoral head slips posteriorly and inferiorly, exposing the anterior and superior aspects of the metaphysis of the femoral neck.
Commonly Associated Conditions
- Obesity
- Endocrine dysfunction
- Primary hypothyroidism
- Pituitary dysfunction
- Hypogonadism
- Cryptorchidism
- Chemotherapy
- Pelvic radiotherapy
- Renal rickets
