[Stiffness of rotation of the forearm associated with contraction of the membrana interossea antebrachii (animal experiments) (author's transl)]

Abstract

In 18 adult cats a wedge osteotomy in the middle of the radial shaft was performed and stabilized with plate fixation in 10 degrees axial deviation. After different times of survival forearm specimens were obtained. In a motion-simulator the elongation pattern of the interosseous membrane during pronation and supination was measured with strain gauges. Remarkable changes of the normal elongation pattern could be observed according to the deviation of the radius.
