Abstract
A prospective study of algodystrophy after fracture of the distal radius was carried out to search for early diagnostic and prognostic criteria. One hundred consecutive patients were assessed by a radiographic score and by a semi-quantitative clinical score at 1, 6 and 12 weeks and 1 year after fracture. The reactive disorders observed could be classified in four groups, each with a different course. There was a close link between patient satisfaction at 1 year and the group to which the patient belonged. Algodystrophy was diagnosed in 26% of cases. Of these, 58% were active and left sequelae at 1 year. A clinical score greater than 7 at 6 weeks predicted 96% of these cases of active algodystrophy. Active algodystrophy was more likely after a severe initial injury and if there was pain at the distal radioulnar joint.
