Cadaveric investigation on radial nerve strain using different posterior surgical exposures for extraarticular distal humeral ORIF: merits of nerve decompression through a lateral paratricipital exposure.

Objective:To determine whether the type of posterior surgical approach for distal humeral fracture open reduction and internal fixation influenced radial nerve strain during simulated operative retraction in a cadaveric model.Methods:Three different posterior surgical exposures: triceps splitting, l
