Cause: Proximally - Saturday night palsy
In spiral groove - fracture of midshaft humerus.
Distal/deep: subluxation of radius.
Consequences: loss of extensors (brachioradialis, extensors, supinators, triceps), loss of sensation over posterior arm, dorsum of hand.
Proximal Median nerve: cause of lesion and consequences
Lesioned by: Supracondylar humerus fracture
