pt has weakness of elbow, wrist, and finger extension- wrist drop - radial nerve injury (C5-T1)

humerus fractures proximal to distal (Axillary, Radial, Median) ARM (FA2020 pg 447)

midshaft fracture will injure the radial nerve where it travels through the radial groove on the posterior surface of the humerus

I originally chose distal shaft, but Median nerve injury at a supracondylar fracture would not cause elbow weakness
