Patient is a 25yo F following a fall from a height. Closed distal 1/3 diaphyseal fracture with no neurological symptoms. Patient sought a rapid recovery without use of an orthosis so consented and proceeded with open reduction and locking plate fixation. Operation was performed prone with the arm resting on a small side support table, the forearm flexed 90deg towards the floor. Midline posterior approach to the humerus, elevation of a lateral paratricipital window from the lateral intermuscular septum - utilising the ascending course of the posterior antebrachial cutaneous nerve as a guide to find the perforation of the radial nerve through the septum. The fracture was reducible entirely through the lateral window distal to the radial nerve. A small medial paratricipital window anterior to the ulnar nerve was opened for lag screwing before positioning the plate. To facilitate proximal plate fixation without having to mobilise the lateral belly of triceps (and with it the radial nerve) we opened an additional proximal working window between long and lateral heads of triceps. Proximal to the aponeurosis it is a simple matter to identify and mobilise the descending course of the radial nerve bundle, protect it, and proceed with proximal instrumentation and plate fixation.
