Summary

Microsurgical techniques offer successful treatment for avulsed fingers, with revascularization achieving 100% survival. While functional outcomes vary, non-medical factors influence surgical decisions for finger replantation and revascularization.

Area of Science:

  • Hand Surgery
  • Microsurgery
  • Trauma Management

Background:

  • Avulsed finger injuries present significant reconstructive challenges.
  • Historically, conventional methods had limited success rates.
  • Advancements in microsurgery have improved treatment options.

Purpose of the Study:

  • To evaluate the outcomes of microsurgical techniques in managing avulsed fingers.
  • To compare the success rates of replantation versus revascularization.
  • To assess functional recovery, including range of motion and sensory restoration.

Main Methods:

  • Retrospective analysis of 59 avulsed finger cases managed between 1986 and 2004.
  • Classification of injuries using the Kay-Wolff system.
  • Comparison of outcomes between microsurgical (39 cases) and conventional (20 cases) treatments.
  • Assessment of survival rates, active range of motion, and sensory recovery.

Main Results:

  • Revascularization achieved a 100% survival rate; replantation had an 80.7% survival rate.
  • Good sensory recovery (4-10 mm static two-point discrimination) was observed in 38% of cases.
  • Over 90 degrees of active motion in interphalangeal joints was achieved in 48% of cases.
  • Microsurgical techniques demonstrated successful treatment, though functional results were variable.

Conclusions:

  • Microsurgical interventions, particularly revascularization, offer high survival rates for avulsed fingers.
  • Functional outcomes (range of motion, sensation) can be suboptimal despite successful revascularization or replantation.
  • Non-medical factors significantly influence the decision-making process for surgical intervention in avulsed finger injuries.
