The DOS fixer for the third proximal fractures of the humerus is based on two Kirschner strings energized and locked by a “double L” bar, stabilized by two steel pins, thus creating a stable closed loop system Favors elasticity in fracture, leading to healing. The system has a telescopic bar that allows distraction and compression in the post-operative to ensure a reduction in the fracture. The system is highly modulated with the possibility of inserting 2 or more wires. The fixing components are entirely titanium, therefore RMN compatible.
With the DOS system, traditional invasive methods can be avoided, even in the presence of osteoporosis. The DOS system is a simple, mini-invasive technique that allows immediate articulation of the joint after surgery.
