The Square Nail for ULNA is a specialized, rigid intramedullary implant used for the fixation of fractures in the shaft of the ulna (forearm bone). Like its radial counterpart, its defining feature is its square cross-section which is engineered to provide excellent rotational stability within the ulnar canal without requiring traditional interlocking screws. This nail is typically inserted near the elbow or wrist joint and offers stable, load-sharing fixation crucial for proper forearm rotation.

Key features include:

• Square Cross-Section: Provides rotational stability and fits snugly within the ulnar canal.

• Intramedullary Fixation: Offers stable, load-sharing fixation.

• Primary Use: Stabilization of diaphyseal fractures of the ulna.

• Material: Available only in Stainless Steel (implied by the code table).

• Multiple Diameters: Available in 2.0mm, 2.5mm, 3.0mm, and 3.5mm.

• Length Range: Lengths range from 200mm up to 300mm.
