Insights

Internal rotation gait in cerebral palsy is common and multifactorial. Key contributing factors include limited external rotation, femoral anteversion, and hip flexor contracture, guiding treatment strategies.

Area of Science:

  • Orthopedics
  • Pediatric Neurology
  • Movement Science

Background:

  • Internal rotation gait is a prevalent characteristic in children with cerebral palsy.
  • Contributing factors are believed to include femoral anteversion, hip rotator imbalance, and hamstring/adductor tightness.

Purpose of the Study:

  • To investigate the prevalence of internal hip rotation in cerebral palsy patients.
  • To identify associated clinical factors influencing this gait pattern.

Main Methods:

  • Retrospective analysis of gait laboratory data from 222 cerebral palsy patients.
  • Group comparison based on maximum dynamic hip internal rotation ( >27° vs. <20°).

Main Results:

  • 27.0% of patients exhibited dynamic hip internal rotation exceeding 27 degrees.
  • Significant differences observed in passive hip external rotation range, femoral anteversion, and hip flexor contracture between groups.

Conclusions:

  • Dynamic hip internal rotation in cerebral palsy is multifactorial.
  • Early intervention for hip flexion contracture may be beneficial.
  • Understanding specific contributing factors is crucial for surgical considerations.
