Summary
This summary is machine-generated.

Syme amputation (SA) in children may not benefit from minimal limb length discrepancy (LLD). Moderate LLD (zone E) showed least prosthesis restriction, with barefoot walking varying by environment and age.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Prosthetics and Orthotics

Background:

  • Syme amputation (SA) preserves the heel pad for weight-bearing without prostheses in pediatric cases.
  • Limb length discrepancy (LLD) aids unaided ambulation but can complicate prosthesis fitting.

Purpose of the Study:

  • To investigate the functional outcomes of Syme amputation in a pediatric population.
  • To determine the relationship between limb length discrepancy (LLD) and functional restriction in individuals with SA.

Main Methods:

  • A voluntary survey collected demographic data, weight-bearing information, and functional scores (TAPES-R, LCI-5) from individuals with SA.
  • Participants classified their LLD using a custom illustration, categorizing it into five zones.

Main Results:

  • Forty-seven individuals with SA participated, with amputation occurring at an average age of 3.7 years.
  • Moderate LLD (zone E) correlated with the least activity restriction (TAPES-R), while barefoot ambulation decreased with age and varied by environment.

Conclusions:

  • Optimal SA management should prioritize functional outcomes and length modulation over solely preserving length.
  • A nuanced understanding of daily activities and prosthetic options is crucial for individualized care in SA patients.
