Abstract

Highlights: The shape and form of the clavicle is neither S, z nor like the f-musical key, but rather resembles a swan’s neck. Therefore, fractures in its 3/5th and 4/5th sections lend well to an intramedullary implant. The primary function of an intramedullary device is to reduce and realign displaced fragments and hold them in place until there is sufficient stabilizing woven callus.

Stability depends on the length, diameter and interference fit of an intramedullary implant bridging the fracture. The antegrade approach to insert an IM implant is suitable for fractures in the 5/10th and 6/10th sections, and the retrograde approach for the 6/10th and 7/10th sections from the sternal end of the clavicle. There is less than 30 degrees of clavicle rotation under 90 degrees of arm elevation, which is less than 45 degrees of the screw turn or quarter of its pitch, so it can scarcely cause a significant loosening of a threaded implant.
