CanPHN Proximal Humeral Intramedullary Nailing System is a surgical system designed to treat fractures in the proximal humerus. The system features a straight nail design for central insertion approach and is intended to improve retention for subchondral bone while potentially avoiding insertion through the fracture.
The system includes nails of various lengths: 12mm, 17.5mm, 28mm, and 46mm. Proximal multi-dimensional interlocking fixation sites are provided, specifically for typical three-part fracture sites, which spare more space for the supraspinatus muscle. Additionally, the system includes cannulated intramedullary nails with diameters of 7, 8, 9, 10 for both left and right humeri.
The system’s proximal locking screw holes (A-D) allow for multi-dimensional interlocking fixation, while the threaded horizontal locking hole maintains the angle and locking screw stability. In any fracture situation, three lateral screws (macrotubercle screw holes A, B, and D) must be used to ensure basic structural stability. The screw type for these screws is 4.5mm multi-dimensional locking screw. The anterior screw (small nodule screw hole C) is indicated for fractures with small nodules fragment and improves structural stability. The screw type for this screw is also 4.5mm multi-dimensional locking screw.
For fractures where the small nodules fragment is large enough to accommodate the screw head, a 3.5mm locking screw should not be inserted into that position. Additional locking screws (macro tuberosity, screw holes A, B, and D) are applicable through the screw heads of the lateral screws to further stabilize the humeral head fixation, especially for osteoporosis.
Upward screw (screw hole E) provides extra support to the medial humeral head and cortex. The screw type for this screw is 4.0mm locking screw. Distal locking is achieved using screw holes F and G, where two interlocking screws are inserted distally to minimize the swing of the nail in the humeral medullary cavity. The interlocking angle is 45 degrees, and the screw type is horizontal locking nail with a diameter of 4.0mm.
CanPHN system also features optional screw-in-screw locking to provide support to the posterior medial of the humerus, which is indicated for osteoporosis. The screw type for this is 4.5mm multi-dimensional locking screw. Optional 3.5mm locking screws (screw-in-screw) are available to enhance stability. Countersunk screw design is also used to minimize implant profile.
Each screw has four suture holes to stabilize the attachment of the rotator cuff muscles. Flattened screws minimize the risk of secondary screw penetration. CanPHN system is a comprehensive surgical system designed to provide stability and support to the proximal humerus during fracture healing, with specific features to accommodate various fracture patterns and bone quality.
