Humerus fracture

Classically the radial nerve can be damaged by a mid-shaft humerus fracture.  The radial nerve courses in the radial groove on the lateral aspect of the shaft of the humerus.  Other associated nerve injuries with humerus fractures include:

  1. Proximal humerus fracture = axillary nerve
  2. Supracondylar humerus fracture = median nerve
  3. Medial epicondylar humerus fracture = ulnar nerve

It is very important to understand that these are not uniform and other nerves could be damaged with any humerus fracture.  Always test median, ulnar, radial, and axillary nerve function in any upper arm fracture!
