Most common form of carpal dislocation is os lunatum and N. ulnar have 2 rami curved around it, one of which is ramus profundus, which is motor.
Answer would be 3, abduction and adduction of fingers are lost.
Not 2. because lesion of N. Ulnar results the clawing of 4th, 5th finger and N. medianus that of the 2nd and 3rd finger, and N. medianus is assumablly intakt.
PS weird question though, cant use it in practise at all. It all depends on whether the hand was dorsiflexed or plantarflexed and often there is no nerve injury.

hey guys,
answer would be 4-weakness to oppose thumb because lunate bone is the MC dislocated carpal bone right and it dislocates anteriorly into carpal tunnel and may compress Median nerve.so median nerve lesions would be seen.
well jacksonknives loss of abduction and adduction of fingers is Ulnar nerve lesion..............

Heh my carpal anatomy is not in place, you are absolutely right. My previous post was rubbish, I was thinking hamate bone while refering to lunate. Yes, lunate dislocation would compress carpal tunnel, so is 4.
