Development of osteoarthritis after fixation of Colles' fracture (older type 4). A retrospective study.

Of 37 patients who were treated for a Colles' fracture (Older type 4) by fixation with either a Kirschner wire or a Rush pin, 29 (78%) subsequently developed osteoarthritis. There were no significant correlations between the subjective or objective end results and the development of osteoarthritis. We conclude that osteoarthritis in patients who have suffered from a Colles' fracture (Older type 4) develops soon after the fracture, but it seldom gives rise to symptoms or influences the function of the wrist.
