Question 27

What is ulnar paradox?

Answer 27

More flexion of fingers 3+4 you’d think is a worse (higher up da arm) damage

When actually:
If fingers 3+4 more flexed it means FCU is still working so is flexing them, so ulnar nerve damage is @ wrist

If 3+4 are less flexed then FCU not working so ulnar nerve damage is at elbow
