Premium Humeral Intramedullary Nail for Enhanced Fracture Support

Proximal humeral fractures are among the most common fractures, accounting for 4%–5% of all fractures. Mechanism of injury: Usually occurs when the elbow strikes the ground or the arm is braced during a fall, especially in elderly patients, or when the shoulder joint directly sustains external force.

• Unique and innovative "nail-in-nail" technology to enhance the fixation effect of proximal locking screws.
• Proximal screws are countersunk screws, with at least three lateral screws implanted to ensure basic structural stability.
• Oblique upward supporting lock provides more stable medial support for the humeral head.
• Multi-planar distal locking to avoid neurovascular structures while providing stable fixation.
• Central implantation of the main nail with an ultra-low notch design to protect the supraspinatus muscle and surrounding tissues.

• Ø3.5 mm interlocking screws: Additional interlocking screws ("screw-in-screw" technique) can be inserted through the head of the lateral screws to enhance internal fixation stability. Particularly effective for patients with poor bone quality.
• Ø4.5 mm interlocking screws: Three screws inserted laterally into the greater tuberosity must be used in all fracture cases.
• Ø4.0 mm ascending screw: Supports the medial calcar region of the humerus, helping to stabilize fractures with medial comminution.
• Ø4.0 mm interlocking screws: Two distal interlocking screws are positioned in different planes to reduce implant toggling.
