Summary
A specialized Chopart prosthesis with a flexible socket and carbon fiber keel effectively treated a pediatric patient with equinus contracture and genu recurvatum. This innovative prosthetic solution enabled pain-free ambulation and athletic participation.
Area of Science:
- Orthopedics
- Prosthetics
- Pediatric Rehabilitation
Background:
- Chopart amputations present functional challenges, often leading to equinus contracture and genu recurvatum.
- Limited research exists on optimal prosthetic solutions for these complex cases.
Observation:
- A pediatric patient with Chopart amputation experienced persistent lower-limb pain and genu recurvatum during ambulation.
- Previous prosthetic interventions were unsuccessful in alleviating pain and improving function.
Findings:
- A custom Chopart prosthesis featuring a flexible inner socket, carbon fiber energy-storing keel, and posterior calf struts was prescribed.
- The patient reported complete pain resolution and regained the ability to participate in athletic activities like soccer.
Implications:
- This prosthetic design offers a functional alternative for pediatric Chopart amputation patients with equinus contracture and genu recurvatum.
- Improved prosthetic technology can significantly enhance quality of life and activity levels in young amputees.
