Definitions
- the invention relates to an anchoring device which can preferably be implanted for stabilization of the spine and has dynamic properties for maintaining a residual mobility.
- the dynamic is due to the special design of the
- Anchoring element allows, this being designed so that the physiological
- Stiffening allow dynamic stabilization.
- some approaches are based on allowing flexibility through articulations on or in the pedicle screws. From the patent (DE4110002C1, 1991) a pedicle screw is known which has a rotary
- a spinal implant which allows a translation via a sliding sleeve along a rod.
- a disadvantage of this design is the limitation of the translation path through buffer (leads to high implant loading) as well as the reduction of the rod diameter in the region of the sliding sleeve (starting point for fatigue fractures observed in practice).
- a similar implant is known.
- the essential, (obvious) distinguishing feature is a variation of the bore diameter, which increases in diameter in the region of the inlet and outlet of the sliding sleeve to allow the storage of a bent rod.
- the disadvantage here is the resulting angular play between the rod and the bone anchor, which counteracts stabilization.
- the object of the present invention is to provide a
- Bone anchor for the spine allows the translational movement along a connecting rod without restricting it to a certain way, and on the other hand fixes the angle position between bone anchor and connecting rod. To compensate for tolerances in the placement of the bone anchor an angle adjustability is desirable, but this should be able to be locked after the adjustment.
- the connecting rod should have a high fatigue strength. A certain bending elasticity of the
- Connecting rod or bone anchor also appears to be advantageous for reducing the forces on the bone anchor.
- Linear bearing is fitted, in which the connecting rod is mounted translationally.
- the linear bearing can be configured as a sliding or roller bearing (eg a ball-and-roller unit).
- the angular adjustability is achieved by the combination with a ball or hinge joint.
- the angular stiff translation of the rod is characterized by a constant in cross section Realized opening within a sliding element.
- a high fatigue strength is achieved by avoiding cross-sectional changes within the load bearing area of the
- Connecting rod between the vertebrae can be used and thus no additional dynamic rod systems are required. While improving the
- the implant according to the invention stabilizes the segment to be treated, whereby a residual mobility is obtained. This is a prerequisite for preventing further progressive degeneration of already degeneratively altered spinal segments. Due to the pure translational
- Movement along the rod can be undertaken with these system corrective spinal procedures, which often can not be performed with other dynamic rod systems because of their low shear stiffness. Movements (translations in anterior, posterior and lateral directions) are prevented so that, for example, the facet joints can be relieved and the position of the vertebrae corrected. Another advantage is that the stiffness differences between treated and untreated segments are low, thereby suggesting a reduction in terminal segment degeneration compared to treatment with other dynamic stabilization systems or fusion systems.
- a motion segment (1, Fig. 1) is the smallest biomechanical unit of the
- a connecting rod (3) is mounted, which either a dynamic stabilization or with conventional Pedicle screws (2) can be combined for spondylodesis.
- the pedicle screw (4) can be implanted in a vertebra (11) (FIG. 1) and has at least one non-fixed linear guide, which allows a translation relative to the connecting element (3). By the linear guide the movement path of the superior vertebral body (10) is forced to the physiological center of rotation (13).
- the pedicle screw (4, Fig. 2) consists of at least one screw shank (41), a
- locking means 46, 56

- An optional connecting element (45) serves to fix the linear guide within the head.
- the head (42) serves to receive the aforementioned components and allows the receptacle of the connecting rod (3) via an opening (4243).
- the connecting rod may have a round (31) or rectangular cross-section (32).
- the pedicle screw is varied in the following versions to show various preferred connection and storage variants. On the function and design of the screw head (42) and its fixing components (44, 45, 46) is in the following
- the pedicle screw consists of a
- Screw shank (41) which merges to the proximal screw shank (412) and with the screw head (42) is connected (Fig. 2).
- the spherical shaft head (412) allows articulated, polyaxial adjustment of the screw head (42) with respect to the screw shaft (41).
- a fixing component (44) for example, a grub screw
- all components are fixed within the screw head.
- the fixation component (44) has the function of permanently fixing the stem head (412) in a defined angular position, when the pedicle screw (4a) is fixed, e.g. is clamped with the fixing element (46).
- the connecting element (45) has the task of the
- Fixing element (46) generated clamping force on the sliding member (43) and the
- the sliding element may also have a contour or a collar (433) for fixing, which slipping of the sliding element (43) in
- the sliding member (43) is a bore (431) in which a round connecting rod (31) is mounted.
- the sliding element (43) is preferably made of a material which is optimized in terms of tribological properties and at the same time biocompatible.
