residual angulation in fractures of the radius. x Friberg KS. x Acta Orthopaedica Scandinavica. [JC:1go] 50(6 Pt 2):741-9, 1979 Dec. x The outcome of residual angulation of the radius after 38 distal forearm x fractures in children was investigated. The period of observation ranged x from 4 months to 10 years and 8 months. The correction of a residual x angulation after a fracture was shown to be governed by three factors. 1. x An increase in the time between healing of the fracture and completed x growth at the epiphyseal plates resulted in a more complete correction. 2. x A larger adaxial dislocation of the epiphyseal plate at the time of x healing of the fracture, reflecting a larger primary fracture angulation x and a greater distance from the fracture to the epiphyseal plate, resulted x in a less complete correction. 3. A more complete correction or x overcorrection of the distal epiphyseal plate increased the correction of x the angulation of the fracture. These findings strongly indicate that the x process of correction of a residual angulation after a healed fracture can x be explained in terms of the combined effects of the direction and amount x of longitudinal growth at the epiphyseal plate. A trigonometrical equation x based on this theory predicted the residual angulations of the fractures, x at follow-up, with an error of less than 1 degree. x
