semi-lunate carpal questions

["Chris Fisher" <killerraptor20@hotmail.com>]

My deepest apologies if I am dredging up a controversial topic.

I have 2 questions:

1. In maniraptorans, does the semilunate carpal restrict the dorsoventral 
movement of the manus? In other words, does the development of this element 
(from fused distal carpals 1 and 2?) restrict the ability of the hand to 
move "up" and "down", and limit it to moving mostly "sideways" (laterally)?

2. In maniraptorans, does the semilunate carpal restrict the movement of the 
fingers?

Any help would be hugely, greatly appreciated.

Chris
