Summary
This study evaluated below-knee amputation using a sagittal flap technique in Chinese patients, finding high healing rates but increased complications in diabetic patients. A modified technique is suggested for better outcomes.
Area of Science:
- Surgical techniques in lower limb amputations
- Vascular surgery outcomes
- Diabetic foot complications
Background:
- Below-knee amputation is a common procedure for limb salvage.
- Ischaemia is a primary indication for amputation.
- Diabetes mellitus is a significant risk factor for poor surgical outcomes.
Purpose of the Study:
- To assess the efficacy and safety of the sagittal flap technique for below-knee amputation.
- To identify factors influencing healing and complications.
- To propose modifications for improved surgical results.
Main Methods:
- Retrospective analysis of 45 Chinese patients undergoing below-knee amputation.
- Sagittal flap technique utilized in all cases.
- Data collected on indication, healing, complications, and patient comorbidities.
Main Results:
- Successful healing achieved in over 90% of patients.
- Ischaemia was the main indication for amputation (84%).
- Higher rates of complications and failure were observed in patients with diabetes mellitus.
Conclusions:
- The sagittal flap technique offers satisfactory healing for below-knee amputation.
- Diabetes mellitus is associated with increased risks.
- A modified sagittal flap technique is recommended to improve outcomes.
