Summary
Thumb amputation due to saw or avulsion injuries has a high survival rate with replantation. Functional outcomes are excellent, indicating replantation is always recommended.
Area of Science:
- Orthopedic Surgery
- Microsurgery
- Trauma Surgery
Context:
- Thumb amputation presents a significant challenge in trauma care.
- Saw injuries and avulsions are common mechanisms of thumb loss.
- Replantation offers a potential solution for restoring function.
Purpose:
- To evaluate the outcomes of thumb replantation in a series of cases.
- To determine the success rates and functional results of thumb replantation.
- To establish guidelines for thumb amputation management.
Summary:
- A study of 72 thumb amputations, primarily from saw injuries (50%) and avulsions (20%), showed an 88.9% survival rate.
- Functional assessments of 52 replanted thumbs revealed 95% achieved good or satisfactory results.
- Primary finger transfer is recommended for thumb absence or destruction in multiple amputation scenarios, with similar positive outcomes.
Impact:
- Thumb replantation is an absolute indication following amputation, offering high success and functional recovery rates.
- Effective management strategies for thumb loss, including primary finger transfer, can significantly improve patient outcomes.
- This study reinforces the importance of timely and appropriate surgical intervention in thumb trauma.
