Summary
Replantation surgery for complete digital amputations shows trends in injury mechanisms and outcomes. Complete amputations have a higher failure rate compared to incomplete ones.
Area of Science:
- Hand surgery
- Microsurgery
- Trauma surgery
Background:
- Replantation surgery has advanced beyond simple reattachment.
- Expertise in microsurgery enhances outcomes for amputated digits.
Purpose of the Study:
- To assess trends in complete digital amputations undergoing replantation.
- To analyze factors influencing outcomes in complex replantation cases.
Main Methods:
- Retrospective study of 171 patients with 278 complete digital amputations.
- Exclusion of all incomplete and partial amputations.
- Data collected from January 1, 1994, to December 31, 2003.
Main Results:
- 53% of injuries were work-related, with saw injuries being the most common mechanism.
- The thumb and proximal phalanx were most frequently involved; injuries occurred more in summer.
- Microvascular failure occurred in 29% of replanted digits, particularly with avulsion injuries.
Conclusions:
- Complete digital amputations present greater complexity than incomplete ones.
- Higher failure rates are associated with complete amputations.
- Understanding injury trends aids in improving replantation outcomes.
