Question 23

What is tenotomy?

Answer 23

Tenotomy is a surgical procedure where
a tendon is partially or completely cut to release tension and improve joint movement.

It is often performed to treat conditions like foot drop or wrist drop, where there is a loss of muscle control or weakness in the affected area.
