Anser

About Anser

The Anser is a novel surgical device specifically designed for the fixation of displaced and/or shortened mid shaft clavicle fractures. The Anser has a one-size-fits-all principle and the procedure is utmost simple.

The concept of the Anser is to re-align the fractured clavicle and to preserve the original length of the bone in a minimally invasive manner. Its design consists of a flexible base pin fabricated from a titanium alloy that has the capabilities to follow the sigmoid-shaped intramedullary canal. The pin has a blunted tip to prevent perforation and screw thread to fixate itself on the medial side of the fracture either against the anterior cortex or the subchondral plate.

On the lateral side the base pin has a plurality of indentations that allow the surgeon to decide on the correct length of the clavicle and the pin intra-operatively. The outside of the lateral fixation device fixates itself into the cortical bone of the lateral fracture element. At the same time it positions itself around the base pin in one of the previously mentioned indentations. The end cap secures this position.

To prevent possible friction and loosening of the implant during rotation of the clavicle around its axial axis while moving of the arm, the lateral fixation device will allow rotation around the base pin whilst continuing to secure its appropriate length.

Hence, the system creates an intramedullary internal fixator.
