Scans make new finger joints more flexible

Finger joint replacement surgery is less successful than other joint ops, but this could soon be improved thanks to computergenerated models.

Surgery to replace the second joint in the finger can reduce pain, but the range of movement does not always improve, and in some cases may worsen. This is partly because it can be hard to get an artificial joint to fit precisely.

now a team at Southampton university is testing a computer-generated model using information from CT and mri scans and motion tracking technology.

This will help them see how the new joint will function before surgery and to place the new joint to provide the best outcome.
