humeral nail 

The multiloc humeral intramedullary nail is an orthopedic implant for the treatment of humerus fractures. It is suitable for two-segment, three-segment, and four-segment fractures of the proximal humerus, especially for comminuted metaphyseal fractures, fractures split to the metaphyseal of the humerus, and proximal humerus fractures combined with metaphyseal fractures. Features 1. Flat head screws can minimize the secondary threading risk. 2. Each screw has 4 holes to stabilize the attachment of rotator cuff muscle group. 3. The center insertion point is designed as a straight nail, which improves the control of the higher strength subchondral bone. In the case of a typical three-part fracture, penetration through the fracture site can potentially be avoided. To make room for the oligovascular supraspinatus muscle. 4. Nail in nail design:improve osteoporosis bone fixation. 5. The proximal locking hole can maintain the Angle stability and…
