[Unstable fracture of the distal radius and its treatment: comparison of three techniques: external fixation, intramedullary pinning and AO plates].
This retrospective study compares 94 distal radius fractures. Sixty one women (median age 66) and 33 men (median age 42) were reviewed clinically and radiologically by a surgeon not involved in treatment. Fractures were classified into three AO groups. Standard X-rays were used for radiological evaluation. Fractures of the distal ulna were evaluated separately. Chi-square tests, Wilcoxon, Mann-Whitney and Fisher's tests were used for statistical evaluation. Women presented mainly "A" type fractures. They were treated by intramedullary pinning. Forty two fractures were grafted, using autogenous bone for young patients and bone substitute for the elderly. Twelve scapholunate dissociations were recorded, all but one were detected in women, 50 years of age or more. Four were painfree, two presented climatic pain and six claimed pain during effort; none had snapping. Radio-ulnar laxity was similar with or without styloid fractures. External fixator and autogenous grafts appeared the most efficient technique for maintaining radial length. Ulnar head fractures were related to a significant higher incidence of sympathetic dystrophy with reduced prono-supination, a correlation not previously noted to your knowledge. This suggests that radius and ulnar head fracture should be classified independently. The amount of pain was not related to classification, internal fixation or gender.
