Application: It is used for the internal fixation of fracture on proximal humerus, fracture of humeral shaft (5cm away from olecranon hook, often accompanied by a closed fracture line) including the stable and unstable fractures, pathologic fracture and delayed union, false joint, proximal humerus fracture combined with diaphysis lengthening, proximal humerus and humeral shaft symphysis fractures. Product Introduction ✓ Medical Background 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. ✓ Features ● 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.
