Clinical Scenario
A 7-year-old girl with spastic diplegic cerebral palsy is referred for gait assessment. She was born at 28 weeks gestation with periventricular leukomalacia. She walks with a posterior walker and can take some independent steps. Her parents are concerned about worsening crouch gait and increased toe-walking. She has previously had botulinum toxin injections to her calf muscles. On examination, she has bilateral hip flexion contractures of 20 degrees, popliteal angles of 60 degrees bilaterally, and ankle dorsiflexion of -10 degrees with knee extended.
Clinical photograph of a 7-year-old child with spastic diplegic cerebral palsy demonstrating typical gait pattern. There is bilateral hip flexion, adduction, and internal rotation (scissoring). The knees are flexed (crouch gait) with equinus at the ankles. The child uses a posterior walker for support. GMFCS Level III. This pattern is amenable to single-event multilevel surgery (SEMLS).

Exam Day Cheat Sheet
Must Mention
- •GMFCS I-V classification
- •Hip surveillance with migration percentage
- •MP 30% = soft tissue, MP 40-60% = bony
- •SEMLS after gait analysis (age 6-12)
- •Silfverskiold test for equinus
- •Botox for dynamic, surgery for fixed
Common Pitfalls
- •Missing hip surveillance
- •Wrong GMFCS levels
- •Wrong MP thresholds
- •No gait analysis mention
- •Wrong Silfverskiold test
- •Missing SEMLS concept
