What are complications of carpal tunnel syndrome?

Complications of carpal tunnel syndrome are uncommon but include atrophy and weakness of the muscles at the base of the thumb in the palm of the hand. This can be a permanent complication if not corrected early enough. This can lead to lack of dexterity of the affected fingers.

What is the prognosis for carpal tunnel syndrome and tarsal tunnel syndrome?

The outlook is generally excellent as carpal tunnel syndrome usually responds to the conservative measures reviewed above. Sometimes surgical operation is necessary and residual weakness can occur.
