Background
- Most common cause of hip disability in adolescents
- Head of femur displaces from epiphysis
- Complications: avascular necrosis, arthritis
Risk Factors
- Obesity
- African-American
- Male:female (3:1)
- During growth spurt (m=13y f=11y)
DDX
Diagnosis
Presentation
- Mild to severe pain hip pain (may have referred knee pain)
- Limp
- May present as acute, chronic, or acute on chronic (following trauma)
Imaging
- AP, Lateral, Frog Leg View B/L
- Widened physis (early finding)
- Displacement of femoral neck to head (late finding)
- Frog Leg view of both sides: high proportion have b/l involvement
- Klein's line
- Line from superior cortex of femoral neck parallel to greater trochanter
- Normally should cross through 1/3 of femoral head
- Line from superior cortex of femoral neck parallel to greater trochanter
Treatment
- Orthopedic consultation in ED
- MRI for ambiguous cases
- Non-weight bearing
- Internal fixation
Disposition
Admission
