Severe crouch gait in spastic diplegia can be prevented: a population-based study

Area of Science:

• Orthopedics
• Pediatric Surgery
• Neurology

Background:

• Severe crouch gait is a common complication in children with spastic diplegia.
• Previous management of equinus gait involved observational methods and isolated gastrocsoleus lengthening.
• The impact of updated surgical protocols on severe crouch gait prevalence was unknown.

Purpose of the Study:

• To investigate the prevalence of severe crouch gait in children with spastic diplegia (GMFCS levels II-III) over 15 years.
• To assess the effect of changes in equinus gait management on severe crouch gait incidence.
• To identify potential contributing factors to severe crouch gait.

Main Methods:

• Retrospective study of 464 children with spastic diplegia undergoing 3D gait analysis.
• Comparison of severe crouch gait prevalence before and after protocol changes.
• Analysis of surgical interventions, specifically gastrocsoleus lengthening versus gastrocnemius recession.

Main Results:

• The prevalence of severe crouch gait decreased significantly from 25% to a stable rate of 0-4% annually after protocol changes (p < 0.001).
• Isolated lengthening of the gastrocsoleus was associated with the development of severe crouch gait.
• Three-dimensional gait analysis and multilevel surgery replaced older methods.

Conclusions:

• Isolated gastrocsoleus lengthening precipitates severe crouch gait in pediatric spastic diplegia.
• Updated surgical management strategies, including gastrocnemius recession and 3D gait analysis, effectively reduce severe crouch gait.
• Severe crouch gait can serve as a valuable indicator for surgical management quality in pediatric cerebral palsy.
