Bolt for connecting vertebra to longitudinal member, e.g. spine

摘要

The bolt or pedicle screw (1) includes a threaded rod (2) having a longitudinal axis (XX) and a head (4) in which there is a channel (5) adapted to receive a spinal support rod. The channel is formed such that its longitudinal axial plane (P) is inclined relative to the longitudinal axis of the threaded rod. The head of the screw being made up of two flanks (6,7), a threaded hole (11) is formed in one of them. An Independent claim is also included for an apparatus to support the spine.
