ABOS Orthopaedic Surgery · Sample question
A 42-year-old man has arm pain and deformity after a fall. Radiographs show a displaced middle-third humeral shaft fracture, and posterior plate fixation is planned. Preoperative wrist and finger extension are intact. During a posterior/lateral exposure, which surgical landmark best identifies the radial nerve at greatest risk as it transitions from the posterior to anterior compartment?
Radial nerve landmark
The radial nerve runs in the spiral groove with the profunda brachii, then pierces the lateral intermuscular septum about 10–12 cm proximal to the lateral epicondyle; this is the key danger zone in humeral shaft fixation. C is suprascapular nerve anatomy. A describes the ulnar nerve’s arm course near the medial septum, not the radial nerve. B is also an ulnar nerve compression landmark. Diagnose radial nerve risk by fracture level and exam; order orthogonal humerus radiographs; treat with planned exposure and direct nerve protection; escalate if postoperative new palsy suggests entrapment or fixation injury.
