Area of Science:

  • Microsurgery
  • Reconstructive Surgery
  • Trauma Surgery

Background:

  • Amputated digits present a significant reconstructive challenge.
  • Successful replantation requires meticulous surgical technique and patient selection.

Purpose of the Study:

  • To evaluate the outcomes of digit replantation in a large patient cohort.
  • To identify factors influencing survival and functional recovery after digit replantation.

Main Methods:

  • Retrospective analysis of 802 digit replantations (592 complete, 210 incomplete) in 549 patients.
  • Detailed review of surgical techniques, including debridement, vascular anastomosis, and fixation.
  • Categorization of complex amputations: distal segment, pediatric, rotational avulsion, and bilateral.

Main Results:

  • Overall survival rate of 90.8% (728 out of 802 digits).
  • High survival rates in specific complex cases: distal segment (94%), pediatric (88.7%), thumb avulsion (88.4%).
  • Complete salvage achieved in a severe ten-digit guillotined case.

Conclusions:

  • Thorough debridement, meticulous vascular anastomosis, and timely management of vascular crisis are crucial for high survival rates.
  • Judicious indication selection, proper bone fixation, nerve/tendon repair, and rehabilitation are vital for improving postoperative function.
