Q

Erb-Duchenne paralysis (C5-C6) (upper plexus and mononeuropathies)

A

Traction on the arm at birth or falling on the shoulder may damage the upper part of the plexus (roots may be pulled out of spinal cord)

Signs: deltoid and supraspinatus are paralyzed (no arm abduction)

Infraspinatus paralysis leads to medial rotation of the arm.

Biceps and brachialis are also paralyzed (no elbow flexion)
Loss of biceps and supinator (weak supination)
Adductors of shoulder are mildly affected (pectoralis major and lat dorsi)

**breach position coming by hand or buttocks position. C5-C6 may be actually injured
