Abstract:
:The accuracy and reproducibility of computed tomography (CT) scanning techniques in assessing tibial version and torsion are measured in this study. A technique of three-dimensional CT reconstruction is introduced to assess the influence of selection and variation of landmarks on rotation measured in the tibia. The authors conclude that, within 2 cm of the articular surface, the level at which the proximal tibial axis is determined has no effect on the degree of torsion measured by CT scan. Furthermore, they conclude that the slope of the proximal tibial cut, with respect to the long tibial axis, has no effect on the measure of tibial torsion. Finally, they conclude that there is no significant difference in tibial torsion measured by reference to the posterior-condylar axis instead of the transtibial axis in cuts below the articular surface.

abstract::Rotator cuff repair is one of the most common surgical procedures done in the shoulder.
