Tendon Transfer Surgery Illustration
Here’s another illustration I did over the summer. Tendon transfer surgery of this sort can be used to restore thumb opposition, which may have been lost due to nerve damage. What is being shown is one of the early steps of the surgery where the FDS is being cut. The tendon will then be pulled back through an incision made at the wrist. Next, a pulley will be made out of the flexor carpi ulnaris through which the FDS tendon will be redirected to the thumb. In the end, the FDS, which used to flex the middle finger, will now control thumb opposition, which has got to be a very weird feeling.
I decided to use a grey background, because I think its more fun to work on than a white background. Drawn in Painter and labeled in Illustrator.
