More Information
Summary:An implant to separate a vertebral cut has an upper portion, lower portion, and inner member. The inner member communicates with a swivelable coupling located at each end of the inner member. Each swivelable coupling also interacts with a respective one of the upper and lower portion, within an inner bore thereof. Movement of the inner member relative to one or both of the upper and the lower portions, via one or both swivelable couplings, translates the upper portion away from the lower portion, about a vertebral cut, to widen the vertebral cut and expand the spinal canal. Swivelable action of the couplings allows angulation of the inner member, relative to a longitudinal axis of the implant, to accommodate a natural lateral shift occurring during a widening of a vertebral cut.
