Congenital proximal radio-ulnar XXXX . Natural history and functional assessment.

@entity1 @entity154 @entity8213 @entity55834
We evaluated the cases of twenty-three @entity1 with thirty-six congenital proximal radio-ulnar synostoses who had been followed between 1938 and 1984. None of the @entity1 had had any attempt at surgical correction or any ipsilateral @entity154 . Emphasis was placed on analyzing the natural history of the lesion in these @entity1 who had not been operated on, and on determining the effect of a fixed position of the forearm on function. Ten @entity1 had unilateral and thirteen, @entity8213 . Their mean age when last examined was twenty-two years (range, three to fifty years). Eight @entity1 were female and fifteen, male. The forearms were fixed in an average of 30 degrees of pronation. The position of the forearm was not found to be related to subjective functional limitations, employment status, or the results of the hand-function test of Jebsen et al. Most @entity1 had few or no functional limitations, and were employed in jobs that demanded extensive use of the forearm. Contrary to the findings of other studies, we observed four distinct radiographic patterns based on the presence of an osseous @entity8213 and the position of the radial head. However, we noted no relationship between any of these patterns and function. We concluded that operative treatment of @entity55834 is rarely indicated, that less emphasis should be placed on the single factor of the position of the forearm, and that objective functional tests should be included in the assessment of these @entity1 .
