Yes, a toe can replace a thumb in a surgical procedure called a toe-to-thumb transfer.
This procedure is a reconstructive option when a thumb is severely damaged or amputated. According to available information, a toe-to-thumb transfer is considered for patients who have sustained a crush or avulsion amputation to the thumb with maintained carpometacarpal stability. This indicates the base of the thumb (where it joins the hand) needs to be relatively intact for the transfer to be successful.
Essentially, the procedure involves surgically transplanting a toe (typically the big toe or second toe) to the hand to function as a thumb. The goal is to restore grasping and pinching abilities significantly impacted by thumb loss. The traumatic loss of a thumb is one of the most devastating hand injuries because of the profound impact on hand function.
Key Considerations for Toe-to-Thumb Transfer:
- Thumb Amputation Type: Toe-to-thumb transfer is beneficial when the thumb is crush or avulsion amputated.
- Carpometacarpal Stability: The base of the thumb needs to be stable.
- Functional Goals: The procedure aims to restore hand function.
