Torsion in femoral fractures in childhood. A longitudinal investigation.

: A photogrammetric method developed for measurement of femoral neck anteversion was used to evaluate the torsion in 28 femoral fractures sustained in childhood and treated conservatively. Spontaneous correction of the initial torsion of 10 degrees to 30 degrees to less than 10 degrees was the rule in a growing femoral bone within 5 to 10 years after trauma.
