What is SCFE?

SCFE (Slipped Capital Femoral Epiphysis) is a shift of the growing ball of the hip relative to the neck of the femur through the growth plate. It is an urgent condition that requires orthopaedic review.

Pain may be felt in the groin, thigh, or knee. Some children limp for weeks before diagnosis. The hip may be stiff and externally rotated.

Stable slips allow walking with a limp, whereas unstable slips cause severe pain and the child cannot bear weight.

What Happens When It Occurs?

Shear forces across a weakened growth plate allow the epiphysis to slip. Continued weight bearing risks further displacement and compromise to the blood supply.

Common Causes and Risk Factors

  • Growth spurts and higher body weight
  • Endocrine disorders or delayed puberty
  • Family history and anatomical variations

Who is Most Affected?

  • Children and adolescents
  • More often boys in early secondary school years

Typical Symptoms

  • Groin, thigh, or knee pain with a limp
  • Outward foot progression and limited hip internal rotation
  • Acute severe pain and inability to bear weight in unstable slips

When to Seek Care

Immediate medical assessment is required for suspected SCFE. Do not allow sport or forced range-of-motion testing.

How We Diagnose

  • Clinical suspicion based on limp and reduced hip rotation
  • X-rays of both hips to confirm the slip
  • MRI for early or subtle cases

Management

  • Urgent orthopaedic referral for in-situ fixation
  • Protected weight bearing with crutches before surgery
  • Rehabilitation to restore gait and strength after fixation
  • Monitoring of the other hip, which can also be at risk

Rehabilitation Milestones

  • Phase 1 (Weeks 0–2 after fixation): Pain control, protected gait, gentle range of motion
  • Phase 2 (Weeks 2–6): Progressive weight bearing, hip and trunk strength
  • Phase 3 (Weeks 6–12): Gait normalisation, cycling, pool exercises, controlled running drills
  • Phase 4 (Months 3–6): Return to running and sport under surgical guidance

Readiness to Progress

  • Pain-free walking with symmetrical step length
  • Hip strength within 90% on testing
  • Running drills completed without pain

Prevention

  • No proven prevention exists
  • Early recognition of persistent limp or knee pain in growing children shortens time to treatment

Australia Snapshot

  • Diagnosed through GP and emergency department pathways
  • More common in boys and in higher body weight groups
  • Bilateral involvement occurs in a notable proportion and is monitored

Latest Insights

  • Suspect SCFE in any limping child with reduced hip internal rotation — early imaging is crucial
  • Stable fixation followed by structured rehabilitation produces good outcomes for most children

Frequently Asked Questions

Yes. Arrange urgent medical review and avoid sport or forced testing.

Most cases are treated with in-situ fixation to stop further slip.

Walking improves over weeks. Running and sport usually resume in months under orthopaedic guidance.

Yes. The other side is monitored closely and sometimes prophylactic fixation is advised.

Short walks with crutches, gentle range, bike and pool as cleared by the surgeon.

Higher slip angles increase future risk. Early treatment and rehabilitation reduce that risk.

Most students return to classes quickly. Sport returns when gait, strength, and imaging milestones are met.
