Definitions

  • the invention relates to an implant for insertion between vertebral bodies of the spine as a placeholder for vertebrae or vertebrae removed from the vertebral column, with a first implant part and a second implant part, which are adjustable in the direction of their coaxial longitudinal axis to change the length of the implant, and with at least one one fixable to the implant parts, facing the adjacent vortex and this at least partially overlapping fixing plate.
  • Such an implant is known from EP 0 950 388 A2.
  • This implant consists of a total of three implant parts, namely two terminal, intended for engagement with the adjacent vertebra terminal implant parts and a central intermediate implant part therebetween, which are connected to each other via threads.
  • Holes are formed in the terminal implant parts which primarily serve to allow access to the interior of the implant parts for introducing bone cement or bone material.
  • These holes are additionally used to be able to attach a fixation plate with a circular collar optionally to a terminal implant parts, for which purpose in the collar openings are formed, with two holes formed in the terminal implant part to cover can be brought. Through the openings bolts can be inserted into the holes.
  • the fixing plate has a slot in the longitudinal direction, which is adjustable in its width, so that a clamping of the bolts is achieved in the holes.
  • the fixation plate is attached to the outer periphery of the terminal implant part and can be used to improve the stability of the spine without preventing accessibility to the implant parts.
  • Restrictions is subject to because the change in length of the implant, the central implants relative to the terminal implant parts by applying a tool to be moved in a circular arc and adjustment by the arrangement of the fixation plate on the outer circumference of the terminal implant parts to the individual circumstances of the patient is not possible ,
  • the invention is therefore based on the object, an implant of the type mentioned in such a way that the position of the fixing plate relative to the implant is variable.
  • the fixing plate is formed by a swirl bearing plate and a protruding from this, the radial adjustment of the fixing plate relative to the implant part serving base plate with a guide rail, and that the one implant part Means are assigned for radial fixing of the bottom plate.
  • This implant is characterized in that a different distance of the vertebral investment plate to the center of the implant part adjustable is and thus a different placement of the implant between the vertebral bodies is possible without having to give up the use of the fixation plate.
  • the advantage of greater variability is combined with the advantage of improved stability, since the radial adjustability of the fixation plate with the vertebral bearing plate relative to the implant part can be terminated by the means for radially fixing the bottom plate. It is very particularly preferred in the context of the invention if each of the two implant parts each have a fixing plate is assigned, since so a further improved stability is achieved.
  • the implant part has an end plate facing the adjacent vertebra with an opening for receiving a clamping means engaging the bottom plate, since this will overcome a restriction on the circumference of the implant part for connection to the fixation plate.
  • the opening is designed as a threaded bore and the clamping means as a clamping screw.
  • the bottom plate is like a fork with at least two forks, in which attack the means for fixing. It is of course possible to provide more than two forks, so that in terms of increased variability and the means for fixing with different pairings of forks can interact, so the fixing plate can be adjusted in their lateral orientation relative to the implant part.
  • a particularly strong connection is used when the forks under the screw head of the clamping screw cross clamping webs.
  • An improved adaptation to the anatomical conditions makes it possible for the turbulence plates to have a convex cross-section, at least one screw opening and a window in the region of the connection to the bottom plate.
  • the screw opening is for
  • the window in the fixation plate serves primarily to allow visual inspection in the area behind the vortex plate.
  • the bottom plate has on the side facing the adjacent vortex at least one anchoring mandrel.
  • the first implant part and the second implant part are designed as tubular sleeves
  • the first implant part is assigned a rotatable threaded ring with a toothing which engages with a ring thread in a thread associated with the second implant part in that a threaded bore is formed in the wall of the first implant for inserting a surgical instrument serving for twisting the threaded ring.
  • the design and the interaction of such first and second implant parts with a surgical instrument is basically known from EP 1 219 266 A1, wherein this implant described therein and therefore not further explained here is suitable for the embodiment according to the invention using the radially adjustable fixation plate and thus overall a minimally invasive procedure is possible.
  • the locking seats are formed, which allow a primary position securing the fixing plate relative to the implant part before the final position assurance is done by tightening the clamping screw.

  • FIG. 7 shows the detail VII from FIG. 6.
  • an implant 1 which serves for insertion between the vertebral body 8 of the spine as a placeholder for vertebrae or vertebrae removed from the vertebral column.
  • This implant 1 consists of a first implant part 2 and a second implant part 3, which are adjustable in the direction of their coaxial longitudinal axis to change the length of the implant 1 against each other.
  • This adjustability is achieved by designing the first implant part 2 and the second implant part 3 as tubular sleeves, the first implant part 2 comprising the second implant part 3 on the outside, with a rotatable threaded ring 4 assigned to the first implant part 2, which engages on its inner peripheral surface Has ring thread, with which this engages in a second implant part 3 associated thread 5.
  • a toothing 6, in particular a bevel gear On the outer peripheral surface of the threaded ring 4 is provided with a toothing 6, in particular a bevel gear, so that the length change in terms of distraction of the vertebral body 8 can be achieved by a rotation of the threaded ring 4 by means of a screwed into a threaded bore of the first implant part 2 surgical instrument.
  • These implant parts 2, 3 have an end plate 9 facing the adjacent vertebra with an opening.
  • This end plate 9 is used for releasably securing a fixable to the respective implant part 2, 3, facing the adjacent vortex and this at least partially overlapping fixing plate 10 by a vortex contact plate 11 as a projecting from this, the radial adjustment of the fixing plate 10 opposite the bottom part 12 serving for the implant part 2, 3 is formed with a guide rail 13. at In the exemplary embodiment illustrated in FIG. 1 and FIG.
  • each of the two implant parts 2, 3 is assigned the fixation plate 10 which can be fixed to the respective implant part 2, 3 by means of fixing the bottom plate 12, these means being shown in FIG Embodiment by a designed as a threaded hole opening of the end plate 9 to be screwed clamping screw 14 are designed.
  • the bottom plate 12 is like a fork with two forks 15 designed to which the clamping screw 14 acts, namely under the screw head 7 of the clamping screw 14 projecting clamping webs 16.
  • the turbulence plate 11 is convex in cross section and further has
  • FIG. 5 shows that, in the region of the connection to the base plate 12, the whirl bearing plate 11 has a window 19 which permits a control of the area behind the whirling plate 11 and at the same time opens up the possibility of guiding a tool or instrument through the window 19.
  • the bottom plate 12 has on the side facing the adjacent vortex a plurality of anchoring mandrels 20, which can penetrate into the vertebral body 8 and thus effect a positional backup before the bone screw 17 to be inserted through the bone screws 18, which are preferably designed as expansion screws, are placed.
  • the required position of the fixation plate 10 relative to the implant parts 2, 3 is determined more suitably by means of an imaging procedure and the fixation plate 10 is securely mounted on the implant part 2, 3 in preparation for the operation.
  • the distraction of the implant 1 to obtain the required height can then be carried out, in order then to carry out the final fixation of the implant 1 by means of the bone screws 18.
