What Is Cubital Tunnel Syndrome?
Reviewed: Dr. Gromatzky
5. Complications
If cubital tunnel syndrome is left untreated, it can cause wasting of the muscles of the hand. The fingers may curl into a claw-like deformity. Even if there is no deformity, the usefulness of the hand may be severely diminished.
Prolonged ulnar neuropathy may also cause permanent damage to the nerve itself. Even if the worst of your symptoms subside, you may still experience decreased sensation in the hand. As a result of these complications, you may no longer be able to type or perform other tasks requiring fine motor skills, at least not as quickly or effectively as you used to.
