Thought experiment: clench your fists - or better yet, imagine your arms had
been amputated somewhere near the elbow joint - and try to pick up and
manipulate objects, grasp things (a mate if you have one handy, lucky you)
or even climb a tree.  Now imagine Mononykus doing the same things.  THEN
tell me how well the forearms of Monnykus  are adapted for grasping.
