  • the present invention provides a spinal implant assembly including a rod which is preferably not a threaded rod, and which is not shown, but which is held in position relative to the spine by a series of bone anchor assemblies as shown generally at 1 0 in Figure 1 .
  • the bone anchor assembly 1 0 includes a fixation member which comprises a bone screw 1 2 having a threaded lower portion which has a fluted area 1 4 and a suitable thread, such as a cancellous thread 1 6.
  • the top of the bone screw 1 2 includes a receptacle such as a cage 1 8 for a post member 20.
  • the cage comprises a plurality of resilient prongs 21 that are constructed by forming slots 22 in the top of the cage.
  • the prongs terminate to form a circular opening with a small bevel 25 to the top which is slightly smaller in diameter than the diameter of the engagement head 23.
  • These prongs 21 can be deformed outward for the insertion of the engagement head of the screw, or inwardly for a compressive locking of the engagement head in a recess 24 which is shown as a spherical recess that receives the outwardly rounded engagement head 23 of the post member 20.
  • the engagement head is shown as a sphere or in a second embodiment as a modified sphere.
  • the top portion of the sphere of the engagement head 23 may preferably be slightly larger than the inner recess or cavity 24 of the cage.
  • the prongs also collectively have an outer surface 26 that tapers inward toward the central longitudinal axis of the screw and anchor assembly so that the bone screw has a pear type shape.
  • a locking cap 30 has a through bore so that it can be fitted over the post member 20.
  • the lower portion of the locking cap 30 forms a skirt 32 that has an upwardly tapered surface 34 on the inside. This can be a curving surface or a conical surface, but in any case, it is slightly smaller than the outer surface 26 of the prongs so as to enable a compressive contraction of the prongs 21 inward about the head of the engagement member 23.
  • the locking cap includes a bushing 36 that may include a rounded surface 38 which mates with the elongated slot 42 in a flanged area of a screw rod connector 40.
  • the slot may also include a corresponding inner rounded contour to allow the bone anchor assembly to be positioned at a variable angle, as well as at a variable distance of offset from the longitudinal axis of the stabilization rod.
  • the rod is received in a channel 39 and secured in position by means such as a set screw which is received in the threaded recess 44 of the screw rod connector.
  • the bushing 36 of the locking cap also includes a plurality of slots 37 that allow the bushing to be expanded outwardly against the sides of the slots 42 of the screw rod connector so that it may be locked in position.
  • the bone anchor assembly further includes a locking nut 50 having a tapered lower portion 52 and a torque receiving head 54 and an internal threaded throughbore.
  • the lower portion 52 has a terminal bevel 56 that can be received in the terminal beveled opening 58 at the top of the bushing 36.
  • the lower portion also includes a tapered portion 52 having an outer diameter which is slightly larger than the inner diameter of the bore on the inside of the bushing.
  • the post member includes a threaded portion 57 that mates with the internal threads on the locking nut 50.
  • A which corresponds to the angulation of the post engagement head in the cage of the bone screw
  • B which corresponds to the angulation of the locking cap in the slot.
  • both of these angles can be locked by the same locking mechanism .
  • the top of the post has a hexagon shape to allow it to be held during tightening . However, this top can subsequently be sheared off.
  • FIG. 5 is a preferred modification wherein the bottom portion of the engagement head 23 is contoured, to form a hollow recess 70 that is pressed upward by a resilient spindle member 72 which is captured in a cavity 74 in the cage.
  • the post member retains its ability to be variably angled in the cage, but it is biased outward against the cavity of the cage so that it is more apt to stay in a position in the cage before it is tightened (i.e. it is less apt to flop.)
  • a construct generally includes two rods on either side of the spinous process, and a series of bone anchor assemblies implanted in adjacent vertebrae.
  • the assembly may also include other components, such as for example, plates, transverse connectors, cables, and hooks.
  • the implants may be made of suitable implantable biocompatible materials, such as stainless steel and titanium, as well as ceramics, and composite materials.
  • the embodiment shown in Figures 6-1 1 includes many components parts that are substantially similar, if not identical, to those shown in the first five Figures.
  • the assembly 1 1 0 includes at least two, and even three, or more bone screws 1 2 which each have the cage 1 8 that acts as a receptacle for the post member 20.
  • the post includes the ball which is received in the cage, and the post further includes a threaded portion 57 that mates with a hexagonal locking nut 1 50.
  • the locking nut has a flanged area 1 52 which tightens down onto the plate, or alternatively, a separate washer can be provided.
  • the screws are connected by means of a screw connector 1 40 which forms part of the plate assembly 1 20.
  • the plate assembly includes the screw connector, which is a plate having several apertures 1 42 that are longer in length along the longitudinal axis of the plate than the diameter of the bushing 1 36 of the locking cap 1 30. This allows some play in the placement of the cap with respect to the plate. This in turn facilitates assembly onto the posts of the screw assembly.
  • the locking cap includes a skirt 1 32 which functions as previously described. The caps 1 30 are press fit into the slots 1 42 prior to the assembly with the screw, and preferably prior to surgery.

Abstract

L'invention concerne un ensemble de fixation de barres destiné à être implanté dans la colonne vertébrale, comprenant un ensemble d'éléments d'ancrage osseux comportant deux points de pivotement au niveau de la connexion entre le point de fixation et la barre. Par ailleurs, l'écart entre le point de fixation et la barre peut être réglé. L'invention utilise une vis à os comprenant une douille à ergots avec une cavité servant à recevoir la tête d'une tige. La douille peut être serrée autour de la tête à l'aide d'un chapeau de fermeture. Pour ce faire, il suffit de glisser le chapeau autour de la douille compressible et de visser la tête vers le haut, dans la cavité, les filets de la tige entrant en prise avec ceux d'un écrou de blocage au fur et à mesure que la tête est vissée vers le haut. De plus, le chapeau de fermeture comprend une bague de raccordement rainurée pouvant être positionnée dans la fente allongée d'un élément d'assemblage pour barres. Le chapeau de fermeture comprend une partie évasée externe permettant d'écarter la bague de raccordement vers l'extérieur pour la verrouiller dans la fente. Dans un autre mode de réalisation, la tête comprend un espace interne servant à recevoir une mèche ajourée dans une cavité située dans ledit espace, pour limiter le jeu dans l'ensemble avant l'opération de serrage. Dans un autre mode de réalisation, les éléments d'ancrage osseux sont reliés à l'aide d'une plaque comprenant des chapeaux de fermeture pré-assemblés dans la plaque.
