What is it about the palmaris longus muscle that makes it a good candidate for a tendon donor?
In conclusion, the tendon of the palmaris longus is the first choice for a tendon donor as it fulfils the necessary requirements pertaining to length, diameter and availability, and can be used without producing any functional deformity.
Are people with palmaris longus stronger?
No statistically significant difference was seen in the grip or pinch strength measurements between subjects who had a palmaris longus tendon and those who did not. This study demonstrates that absence of the palmaris longus is not associated with a decrease of grip or pinch strength.
