The Relationship of Multiplanar Distal and Uniplanar Proximal Interlocking Screws to Neurovascular Structures with the Depuy Synthes Humeral Nail-EX: An Anatomic Study

Abstract

When using the DePuy Synthes Humeral Nail-EX, AM-PL screws may risk the median nerve and brachial artery; thus, this trajectory is not recommended. The LACN may be at risk with A-P and to a lesser degree, anterolateral to posteromedial screws. Proximally, interlocking devices in zone 3 of the humeral head may risk the axillary nerve.
