Expert Cannulated Humeral Nail

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 Cannulated Humeral Nail can be inserted in an antegrade or retrograde approach and includes spiral blade, standard, and compression locking options. The distal locking holes on the Cannulated Humeral Nail are angled for stable, multiplanar fixation. The nail is available in 7.0 mm, 9.0 mm, and 11.0 mm shaft diameters with proximal ends of 7.0 mm, 9.0 mm, and 11.0 mm, respectively. Lengths will be offered from 190 mm to 320 mm in 10 mm increments. 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. A 5 bend is located 55.0 mm from the proximal end, allowing an off-axis entry site to minimize damage to the articular surface. Distal locking holes on the Cannulated Humeral Nails are angled 45 from each other for stable, multiplanar fixation anterolaterally and/or anteromedially, and to reduce the possibility of skiving on the lateral supracondylar ridge. The use of both distal holes will minimize toggle of the nails distal end. A locking end cap is included in the system to secure the spiral blade in the proximal nail slot, creating a angular stable construct. The Expert Cannulated Humeral Nail uses newly designed instrumentation and new 4.0 mm Titanium Locking Screws with a T25 StarDrive recess.

Expert Humeral Nail: End Caps for Locking Screws

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.
