Function ten years after Colles' fracture.

There are no data in the literature concerning the outcome of Colles' fracture beyond six years. One hundred consecutive patients with displaced Colles' fractures were reviewed ten years after the injury. Function, radiographic anatomy, osteoarthrosis, and reflex sympathetic dystrophy (algodystrophy) were all objectively assessed. By the time of this review, 35 patients had died. Eighty-five percent of those surviving had a satisfactory outcome. Forty-two percent had improved functionally in ten years and 20% had deteriorated. Initial and ten-year radial shortening and early finger stiffness significantly correlated with final outcome. Dorsal angulation influenced early but not ten-year function. Sixty-two percent of those with an unsatisfactory result had objective features of reflex sympathetic dystrophy, compared with only 6% of those with a satisfactory result. Osteoarthrosis was found in 37%, but in only 4% was it associated with an unsatisfactory outcome.
