Pseudarthrosis (or "nonunions") is the movement of a bone at the location of a fracture resulting from inadequate healing of the fracture.

Pseudarthrosis can also result from a developmental failure.

Etymology

The Latin root "pseud" means false and "arthrosis" means joint. "Pseudarthrosis", then, is a false joint. In the case of a 'non-union' , a fracture that does not heal, this is often evidenced by the obliteration of the medullary cavity of a long bone at the site of the non union. This non union is not a true joint, and has no ligamentous support, but often has motion, and remodels into a rounded end that looks like a true joint.

Treatment

The point of movement can be treated with electrical stimulations that hopefuly will trigger the bone cells to form the hydroxyapatite structure that keeps bones from bending too much. More recently, non-unions are treated by bone grafting, internal fixation, and external fixation, including a technique pioneered by Ilizarov, used to compress the bones at the site of the fracture.
