Expert Humeral Nail: End Caps for Locking Screws
The expert cannulated humeral nail is indicated for fractures of the proximal humerus, humeral shaft, malunions/nonunions, and impending pathologic fractures. It has a universal design for the right or left humerus, and for antegrade or retrograde insertion. The locking options include spiral blade locking (using the current spiral blade for humeral nail), standard locking (with 4.0 mm locking screws), and compression locking. The current locking end caps are compatible with all locking options. To accommodate this universal use, the current end cap also locked the most proximal screw causing the screw to bend slightly.
A new nonlocking end cap has been specifically designed for use with the locking screws only. This end cap has a shorter distal extension to allow clearance for the use of screws in proximal locking. They are available with 0 mm, 5 mm, 10 mm, and 15 mm extension. The new end caps are color coded for easy differentiation.
