What is thenar muscle atrophy?
The recurrent branch of the median nerve supplies the thenar muscles via the thenar branch. Therefore when the Thenar branch is compressed and the transmission impeded the mucsles atrophy over time. Loss of function is typically due to the Abductor Pollicis Muscle which provides most of the bulk to the thenar eminence.Click to see full…

Also to know is, what causes Thenar atrophy?Atrophy of thenar muscles can be caused by a variety of clinical conditions. Although thenar atrophy is commonly associated with carpal tunnel syndrome (CTS)1; it is also associated with liver cirrhosis2, thoracic outlet syndrome3 and Weill-Marchesani syndrome4.Also Know, what are the thenar muscles? Thenar muscles. The thenar musculature consists of four muscles, named abductor pollicis brevis, adductor pollicis, flexor pollicis brevis, and opponens pollicis. Located on the radial side of the palm, they form together the ‘ball’ of the thumb known as the thenar eminence. Secondly, what causes atrophy of the thumb muscle? Along with a more common thumb deformity caused by osteoarthritis and rheumatoid arthritis, thumb deformities can also be a result of thenar wasting, caused by median nerve injury or compression.How do you strengthen Thenar muscles? Thenar eminence exercises Thumb flex and extension. Raise your hand, making sure that your thumb is positioned away from your fingers. Thumb extension with rubber band. Lay your hand flat on a table or other hard surface. Hand grip exercise. Pinch strength exercise. Thumb-to-finger touch.
