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.

摘要： A device for spinal osteosynthesis includes an elongated bar having two parallel, spaced longitudinal slots extending parallel to the bar length. The slots define a central bar branch and two side bar branches flanking the central bar branch. A plurality of fasteners extend from the bar; each fastener has a shank to be implanted; a head provided at an end of the shank; and a groove provided in the fastener head. The groove has a bottom and divides the head into two leg portions. The central bar branch is received by the groove and is in engagement with the bottom thereof. The leg portions extend through the slots and straddle the central bar branch. A nut is secured to the head of each fastener and abuts a surface of the bar for tightening the fastener to the bar.

摘要： A fastener for insertion through aligned holes of two components to be secured to one another by the fastener. The fastener includes a shaft portion having an end; a fastener head disposed at said end; and a retaining arrangement for maintaining the fastener captive by the components. The retaining arrangement includes a conical collar situated between the shaft portion and the fastener head. Further, the conical collar surrounds the axis and has a maximum diameter base oriented toward the fastener head. The conical collar is provided with radial recesses. The retaining arrangement also has a neck part surrounding the shaft axis and disposed between the fastener head and the conical collar.

摘要： The present invention is a device for the straightening, fixing, compressing, and elongating of cervical vertebrae. The present invention includes a pair of rods extending to occipital plates. The occipital plates conform to the shape and inclination of the occiput. A connecting plate is attached to the ends of the occipital plates. A pedicular clamp having hooks is attached on one of the rods. A hook is connected to another of the rods. Screws are provided so as to secure the occipital plates and the connecting plate to the occiput and the connecting plate to ends of the occipital plates.

摘要： A spinal osteosynthesis device includes a plurality of implants, each having a yoke and an anchoring arrangement carried by the yoke for securing the implant to a selected vertebra. The device further has a connecting bar crossing each yoke; and a plurality of clamps tightening the bar to each yoke. Each clamp has a clamp body; and a pair of generally parallel-oriented claws spaced from one another by a slot and extending from the clamp body. The claws partially surround the respective yoke. The clamp body carries a tightening arrangement for rocking the clamp body about the connecting bar to tilt the claws toward the connecting bar so that the yoke is clamped thereagainst.
