摘要：
The invention relates to an implant for expanding a spinal canal having an upper portion, a lower portion, and an inner member. The inner member communicates with a swivelable coupling located at each end of the inner member within the implant. Each swivelable coupling also interacts with a respective one of the upper and lower portion, within an inner bore thereof. Accordingly, 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. The swivelable action of the couplings during translation 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.
