Thumb Reconstruction
Advanced reconstruction of absent or damaged thumbs using toe-to-thumb transfer or microsurgical techniques.
What it is
The thumb is responsible for much of the hand's gripping and pinching function. Thumb reconstruction rebuilds a missing or damaged thumb, using techniques such as moving the index finger into the thumb position, or transferring a toe to the hand with microsurgery.
Who it’s for
- People who have lost part or all of the thumb through injury
- Children born with an absent or underdeveloped thumb
- Those with a thumb affected by tumour removal
- People in suitable general health, assessed for longer surgery
How it’s done
-
Step 01
Surgery is usually done under general anaesthesia and can take several hours.
-
Step 02
The hand and the planned donor part, such as a toe or index finger, are assessed.
-
Step 03
The donor part is moved into the thumb position, with bone, tendons and nerves joined.
-
Step 04
In toe transfer, blood vessels are joined under a microscope.
-
Step 05
The hand is dressed, splinted and closely monitored, followed by hand therapy.
Recovery time
A hospital stay is usually needed, and hand therapy often continues for several months. Recovery varies with the technique used. Your surgeon will advise based on your assessment.
Results
Grip and pinch function may improve gradually as therapy progresses. The rebuilt thumb usually differs from a natural thumb, and further refinement surgery is sometimes needed.
Results vary from person to person.
