The hand complications of Colles' fractures.

Two hundred and thirty-five patients with displaced Colles' fractures were followed to union, and 209 patients to six months, specifically searching for hand pathology. The incidence of carpal tunnel syndrome was seventeen per cent at three months and twelve per cent at six months. The patients with the syndrome were significantly older and their fractures showed significantly greater residual dorsal angulation. Sixteen patients developed Dupuytren's disease between three and six months, when the incidence was eleven per cent. These patients were significantly older and had average fractures and anatomical results. All cases were mild, with only two contractures. Twenty-one patients were reviewed at a mean of 20.7 months post-fracture, when no case had significantly progressed.
