SCFE: Hip Emergency in Adolescents

In an adolescent, hip, groin or knee pain with limping needs prompt assessment of the hip. A normal body weight does not exclude SCFE; suspected SCFE requires urgent assessment without weight-bearing.

Quick Answers

Why can hip pain be referred to the knee?
It is a phenomenon called 'referred pain': the hip and knee share the same innervation, so a hip problem (such as SCFE) can present as knee pain. An adolescent with knee pain without an obvious local cause should always be evaluated at the hip as well.
Is SCFE really an emergency?
Yes. Once suspected or confirmed, it is important that the teenager **no longer bears weight** on the limb and is managed promptly: waiting increases the risk that the slip will progress and that complications develop, particularly affecting blood supply to the femoral head. For this reason, evaluation and treatment decisions are taken without delay.

Knee pain may have hip origins

In adolescents, hip, thigh or knee pain with limping may originate in the hip. Prompt assessment is needed.

⚠️ Medical Emergency - Go to ER Immediately

SCFE (Slipped Capital Femoral Epiphysis) requires urgent evaluation. The child must NOT walk until seen.

Red Flags - Seek Immediate Care:

  • Adolescent limping or refusing to walk
  • Groin, thigh, or knee pain (may radiate)
  • Leg turns outward when bending hip
  • Overweight adolescent with hip symptoms

📞 Call 118 or go directly to the nearest Pediatric Emergency Department

Slipped capital femoral epiphysis (SCFE) is a slippage of the femoral head relative to the neck through the still-open growth plate. It typically affects adolescents in their growth spurt, more often males and overweight teens, and must be recognized quickly: it is considered a true orthopaedic emergency. Symptoms can be subtle: new-onset limping without clear trauma, hip, groin, or referred knee pain, difficulty rotating the limb internally, and a tendency to keep the foot turned outward. When an adolescent reports knee pain without a clear local cause, it is essential to also evaluate the hip. The suspicion is confirmed by clinical examination and targeted imaging. Care is generally surgical, aiming to stabilize the slip and prevent worsening; timing and modalities are decided rapidly, case by case, including monitoring of the contralateral hip.

If SCFE is suspected, the young person should not bear weight or perform exercises: urgent emergency assessment is needed. Adolescents of normal weight can also be affected.

🚨Watch the Overweight Teen with Limp

SCFE often affects adolescents during the pubertal growth spurt; excess weight is a risk factor but normal weight does not exclude it. Suspected SCFE requires stopping weight-bearing and urgent same-day assessment. Treatment aims to limit further slippage and complications but cannot eliminate every risk.

Assessment and treatment

When to seek evaluation

  • Recent onset limping in adolescent
  • Hip, groin or knee pain
  • Limited hip internal rotation
  • External rotation of the limb during hip flexion
  • Overweight adolescent with joint symptoms

What is evaluated

  • Careful clinical examination without forcing hip movements when SCFE is suspected
  • History of limping and previous weight-bearing ability: the child is not asked to walk to test a suspected SCFE
  • Hip X-rays in anteroposterior and lateral projection
  • MRI only if X-rays are doubtful or negative and clinical suspicion persists, without delaying non-weight bearing, urgent referral and treatment
  • Contralateral hip evaluation

Treatment options

  • Early surgical stabilisation (in situ fixation)
  • Non-weight bearing until surgery
  • Contralateral hip monitoring
  • Post-operative rehabilitation physical therapy

Frequently Asked Questions

Why can hip pain be referred to the knee?▼
It is a phenomenon called 'referred pain': the hip and knee share the same innervation, so a hip problem (such as SCFE) can present as knee pain. An adolescent with knee pain without an obvious local cause should always be evaluated at the hip as well.
Is SCFE really an emergency?▼
Yes. Once suspected or confirmed, it is important that the teenager **no longer bears weight** on the limb and is managed promptly: waiting increases the risk that the slip will progress and that complications develop, particularly affecting blood supply to the femoral head. For this reason, evaluation and treatment decisions are taken without delay.
Can SCFE affect both hips?▼
Yes, in a non-negligible proportion of cases the contralateral hip can also be involved, often within months of the first diagnosis. For this reason, after surgery on the affected hip, the other hip is **monitored over time** and in selected cases preventive treatment is discussed with the family.
Why is it more common in overweight teenagers?▼
Excess weight increases the **mechanical load** on the femoral growth plate, which is still vulnerable during the pubertal growth spurt. Hormonal factors typical of adolescence also contribute. This is why SCFE and weight management often need to be addressed in parallel, both initially and during follow-up.
How can families recognize early signs?▼
Warning signs not to underestimate are: limping appearing without real trauma, **vague pain in the hip, groin, thigh or knee**, tendency to keep the foot turned outward when walking, difficulty sitting cross-legged. In an adolescent showing these signs, especially if overweight or in a rapid growth phase, a prompt orthopaedic evaluation is appropriate.
Can the child return to sports after surgery?▼
Generally yes, but with individualized timing and modalities. After stabilization, a period of protected weight-bearing and progressive rehabilitation follows. Return to sport is gradual, prioritizing low-impact activities, and the final decision on competitive sport is made case by case, also considering the status of the contralateral hip.
