Area of Science:

  • Surgical techniques
  • Orthopedic surgery
  • Amputation procedures

Background:

  • Transtibial amputation is a common procedure for limb salvage and treatment of severe lower extremity trauma.
  • Traditional posterior flap techniques can lead to complications such as wound dehiscence and poor healing.
  • Optimizing flap design is crucial for successful amputation outcomes.

Purpose of the Study:

  • To present a modified posterior flap technique for transtibial amputation.
  • To improve wound healing and reduce complications associated with transtibial amputations.
  • To offer a potentially superior surgical approach for lower limb amputations.

Main Methods:

  • A modified posterior flap technique was developed for transtibial amputation.

  • The technique involves a thick posterior fascio-myocutaneous flap, extended at least 5 cm beyond traditional lengths.
  • Dual-layer fascial closure and proximal translation of the suture line were incorporated.

    • Main Results:

    • The modified flap technique aims to provide robust tissue coverage and vascularity.
    • Dual fascial closure is intended to enhance wound edge apposition and healing.
    • Proximal translation of the suture line may reduce tension on the distal wound.

    Conclusions:

    • The presented modified posterior flap technique offers a novel approach to transtibial amputation.
    • This technique has the potential to improve healing and decrease morbidity in amputation surgery.
    • Further clinical studies are warranted to validate the long-term efficacy and benefits.
