Atrophic nonunion of the clavicle: treatment by compression plate, lag-screw fixation and bone graft.

We describe a new surgical treatment of atrophic nonunion of the clavicle. The nonunion is excised by cuts at 45 degrees to the long axis and repair uses 3.5 mm pelvic reconstruction or dynamic compression plates, with a lag screw to provide interfragmentary compression. The site is grafted with cancellous bone. We have been successful in all seven patients, with early return to normal function. The consequent narrowing of the shoulder girdle is fully acceptable for appearance and function.
