Humeral (Humerus) Nail

Specifications - Humeral (Humerus) Nail

Humeral (Humerus) Nail System is the realization of superior biomechanical intramedullary stabilization.

The compression screw is pushed against the proximal Partially Threaded Locking Screw (Shaft Screw) that has been placed in the oblong hole, drawing either the distal or the proximal segment towards the fracture site. In stable fractures, this has the biomechanical advantage of creating active circumferential compression to the fracture site, transferring axial load to the bone, and reducing the function of the nail as a load bearing device.

This ability to transfer load back to the bone can reduce the incidence of implant failure secondary to fatigue. Typical statically locked nails functioning as load bearing devices have reported failure rates in excess of 20%.

Common 4mm cortical screws simplify the surgical procedure. Fully Threaded Locking Screws are available for regular locking procedures.Partially Threaded Locking Screws (Shaft Screws) are designed for application of apposition/compression. One common Humeral Compression Screw to close the fracture site, and End Caps in six sizes are available to provide an improved fit for every indication to allow nail length adaptation after insertion and to prevent bone ingrowth.

Sizes and Uses of Humeral (Humerus) Nail


Uses

Humeral (Humerus) Nail is indicated for:

  • Humeral Nail is intended to provide temporary stabilization of various types of fractures, malunions and nonunions of the humerus.
  • The nails are inserted using an opened or closed technique and can be static, dynamic and compression locked.
  • The subject and predicate devices are indicated for use in the humerus.
  • Types of fractures include, but not limited to fractures of the humeral shaft, non-unions, malalignments, pathological humeral fractures, and impending pathological fractures.
