Summary
Community ambulation after lower-extremity amputation (LEA) significantly decreased post-surgery. Key risk factors for impaired mobility include major amputation level, diabetes, hypertension, and pre-existing mobility issues.
Area of Science:
- Vascular surgery
- Rehabilitation medicine
- Public health
Background:
- Lower-extremity amputation (LEA) patterns and post-operative ambulation rates are critical indicators of patient outcomes and healthcare effectiveness.
- Understanding risk factors for community ambulation failure post-LEA is essential for targeted interventions.
Purpose of the Study:
- To analyze the current trends in lower-extremity amputation (LEA) within a Chinese population.
- To identify independent risk factors associated with the failure to achieve community ambulation after LEA.
Main Methods:
- A retrospective study design was employed.
- Data were collected from 189 consecutive adult Chinese patients undergoing LEA between 1995 and 1997 at a tertiary hospital.
- Logistic regression analysis was used to determine risk factors for ambulation failure.
Main Results:
- The mean age of patients undergoing LEA was 74.1 years, with vascular occlusive disease and infection being primary causes.
- A significant decline in community ambulation was observed, dropping from 66.1% before LEA to 29.9% at 12 months post-LEA.
- Major amputation level, diabetes mellitus, hypertension, pre-existing inability to ambulate, and prosthesis use failure were identified as significant independent risk factors for poor ambulation outcomes.
Conclusions:
- The study highlights a concerning decrease in community ambulation post-LEA, indicating a need for improved post-operative management.
- Aggressive rehabilitation strategies and targeted interventions are crucial to enhance functional ambulation and community reintegration for amputees.
