Ring avulsion injuries can be successfully treated with surgical intervention, including revascularization and replantation. Most patients with salvaged fingers reported satisfaction with the outcome.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Trauma Surgery

Background:

  • Ring avulsion injuries present complex challenges in hand surgery.
  • Understanding the correlation between injury severity and surgical outcomes is crucial for patient management.

Purpose of the Study:

  • To analyze the outcomes of surgical management for ring avulsion injuries.
  • To correlate the extent of injury and surgical techniques with patient results.
  • To propose a classification system for these injuries.

Main Methods:

  • Retrospective review of 55 cases of ring avulsion injury.
  • Analysis of surgical interventions: primary amputation, revascularization, and replantation.
  • Evaluation of functional outcomes, including return-to-work time, range of motion, and sensory recovery.

Main Results:

  • Of 52 patients with inadequate circulation, 44 underwent salvage attempts.
  • Successful salvage included 19 revascularizations and 16 replantations.
  • Functional outcomes showed good range of motion and sensory recovery in a significant percentage of salvaged digits.

Conclusions:

  • Amputated digits due to ring avulsion are often salvageable with appropriate surgical intervention.
  • A proposed classification system incorporating skeletal injury is suggested.
  • Most patients are satisfied with successful digit salvage.
