What are the symptoms of neurogenic atrophy in thenar muscle from nerve injury?
3 doctors weighed in across 2 answers
Thenar atrophy: The thenar muscles are at the base of the thumb. Normally they are rounded and when there is atrophy the thenar eminence becomes flat. The thenar muscles are used to perform fine motor movements between the thumb and fingers such as picking up a coin, buttoning a shirt, or turning a key. The most common condition is carpal tunnel syndrome. See a neurologist for evaluation.

Thenar atrophy: Thenar muscle weakness results in thumb abduction weakness. This movement is holding the thumb straight up when the back of your hand is turned down (not shown in the picture). It should be able to overcome some resistance to adopt this position. You may also see a dimple in the muscle area at the base of your thumb.
