Q

what nerves does the humerous make contact with and how can they be damaged

A

axillary nerve -winds around surgical neck of humerus - damaged by shoulder disslocation

radial - runs in radial (spiral) groove and can be damaged in humoral shaft fractures

ulnar - runs posterior to medial epicondyle and is superficial - damaged in fractures and dislocations of elbow joint

median nerve - runs anterior to distal humerus - damaged in supracondylar fractures of the humerus and dislocaton of elbow joint
