The side-to-side flap technique in below-the-knee amputation with long stump

Area of Science:

• Orthopedics
• Surgical Techniques
• Rehabilitation Medicine

Background:

• Below-the-knee amputation presents challenges in wound healing and residual limb shaping.
• Optimizing stump length is crucial for prosthetic fitting and patient mobility.

Purpose of the Study:

• To evaluate the efficacy of the side-to-side flap technique in below-the-knee amputations.
• To assess wound healing outcomes and residual limb characteristics for prosthetic use.

Main Methods:

• A cohort of 23 patients undergoing below-the-knee amputation were treated using the side-to-side flap technique.
• Stump length, wound healing, and prosthetic compatibility were analyzed.

Main Results:

• Primary wound healing was achieved in 74% of patients.
• Stump lengths varied (27%-70% of normal limb), with a mean of 56%.
• Longer stumps did not correlate with increased wound complications, and all stumps were nonbulbous and prosthetic-compatible.

Conclusions:

• The side-to-side flap technique facilitates successful wound healing and optimal residual limb shaping for below-the-knee amputations.
• This surgical approach enables limb length preservation, aiding in prosthetic use and reducing energy expenditure during ambulation.
