    摘要： An osteosynthesis system for vertebral arthrodesis, having at least one vertebral compression or distraction bar capable of extending over a portion at least of the rachis; at least one vertebral anchoring member having an end head with a spherical surface, an intermediate shank and a vertebral anchoring portion; and, associated with each anchoring member, a common support for receiving, coupling and immobilizing the vertebral anchoring member and the bar, the common support including a first concave housing for receiving the bar, a second concave housing, for receiving the spherical head, and a screwthreaded member, for immobilization of the bar and the anchoring member on the support, the immobilization member having at least one nut which is screwed onto a screwthreaded portion of the support. The first housing is disposed to the exterior of the screwthreaded portion of the support and is open laterally and upwardly, in opposite relationship to the rachis, so that the bar is immobilized by a peripheral portion of the nut.

    摘要： A spinal implant system including a spinal rod, a first clasp and a second clasp, a connecting element having a head and a shank connecting the first and second clasps, a first fastener for fastening the body of the first clasp to the spinal rod, a second fastener for fastening the shank of the connecting element to the body of the first clasp and a retainer for retaining the second clasp onto the head of the connecting element so that the second clasp can disengage itself from the head only in a direction toward the first clasp. The first clasp is adapted to be fixed to the vertebrae by a hook thereon. The second clasp is adapted to be fixed to the vertebrae by a hook thereon.

    摘要： An implant for replacing a removed vertebra includes an outer sleeve having a longitudinal axis and a peripheral inner surface. The inner surface has a series of axially adjoining, peripheral grooves lending the inner surface a sawtooth-shaped configuration when viewing the inner sleeve in axial section. The implant further includes an inner sleeve having a longitudinal axis and a peripheral outer surface. The outer surface has a series of axially adjoining, peripheral ribs lending the outer surface a sawtooth-shaped configuration when viewing the inner sleeve in axial section. The inner sleeve is telescopingly received in the outer sleeve such that the series of axially adjoining, peripheral ribs of the outer surface engage into the series of axially adjoining, peripheral grooves of the surface in an interfitting relationship. The sawtooth-shaped configurations of the inner and outer surfaces are oriented such that in normal operation the sleeves are prevented by the interengaging sawtooth configurations from being telescoped into one another, but are allowed by ratchet action to telescope outwardly from one another. The inner sleeve is radially sufficiently resilient to allow alternating radial compression and expansion during the ratchet action.
