Area of Science:

  • Reconstructive Microsurgery
  • Trauma Surgery
  • Limb Replantation

Background:

  • Microsurgical techniques have advanced, leading to higher survival rates for amputated extremities.
  • Improved ischemia time tolerance through cold storage and perfusion aids limb salvage.

Purpose of the Study:

  • To review the progress and current status of micro- and macroreplantation techniques.
  • To highlight advancements enabling limb preservation in complex traumatic injuries.

Main Methods:

  • Application of microsurgical techniques, including vessel anastomosis.
  • Utilizing cold storage or perfusion to extend ischemia time.
  • Employing vein graft interposition and heterotopic transplantation for extremity preservation.
  • Considering emergency free flaps and secondary reconstruction for soft tissue and bone defects.

Main Results:

  • Microvascular digital replantation is feasible, even distal to the distal interphalangeal joint in adults.
  • Finger amputations in children represent a primary indication for replantation.
  • Techniques allow for extremity preservation in crush injuries and multiple amputations.
  • External fixation aids in maintaining extremity length.

Conclusions:

  • Modern microsurgical advancements have significantly improved outcomes in limb and digit replantation.
  • Comprehensive strategies, including secondary reconstruction, are crucial for optimizing functional results.
  • Replantation offers a viable option for limb salvage in a wide range of traumatic amputations.
