Hey guys,
Just wondering what muscles/innervation would do flexion of the DIP and PIP?
Specifically, why do we get flexion of the DIP and PIP in for example ulnar claw hand? Or in a distal median nerve injury?
Its to my understanding that say for the 4th and 5th digit @ the DIP, that the ulnar nerve does both extension and flexion, so im just confused with injury why we get flexion.
Thanks
