difficulty flexing the arm, variable sensory loss.

As musculocutaneous nerve supplies biceps brachii, 
coracobracialis and brachialis, there would be loss of 
elbow flexion, supination of the forearm. Although bicpes 
is also a weak flexor of the shoulder joint and 
coracobracialis is a weak adductor of the shoulder joint. 
these actions are still maintained due to the action of the 
pectoral muscles (supplied by the medial and lateral 
pectoral nerves mainly responsible for horizontal flexion)
and latissimus dorsi (supplied by the thoracodorsal nerve 
beaing mainly an adductor of the shoulder joint).
