An improved technique for below knee amputation

Area of Science:

• Surgical Techniques
• Amputation Procedures
• Vascular Surgery

Background:

• Below-knee amputations are common surgical procedures.
• Existing techniques may have limitations in blood supply conservation and safety.
• The need for improved amputation methods is ongoing.

Purpose of the Study:

• To describe a novel technique for below-knee amputation.
• To evaluate the safety and efficacy of this new surgical approach.

Main Methods:

• A below-knee amputation technique utilizing a long and broad posterior flap.
• Distal division and ligation of main blood vessels.
• De-epithelialization and burial of "dog ear" tissue for stump padding.

Main Results:

• The described technique conserves maximum blood supply to the residual limb.
• This method has demonstrated greater safety compared to previously reported amputation techniques.
• The "dog ear" modification provides enhanced stump padding.

Conclusions:

• The novel posterior flap technique for below-knee amputation offers significant advantages.
• This approach enhances patient safety and preserves vascularity.
• Further studies may validate its widespread clinical application.
