Definitions

  • the state of the art concerning total spinal disc replacement device insertion is the anterior approach, i.e. true anterior, anterolateral (oblique) or true lateral.
  • the surgeon decides between transperitoneal or retroperitoneal approaches, depending on the treated level or his personal experience.
  • major vessels e.g. aorta, vena cava
  • the anterior approach to the spine is often performed in the presence of vascular surgeons thereby causing extra costs.
  • a prosthetic device for transforaminal insertion into an intervertebral space is known from US 2004/0225365 EISERMANN.
  • This known prosthesis comprises two components having an articulating surface each in order to permit articulating motion between the first and second components and consequently of the adjoining vertebrae.
  • the transforaminal path disclosed might cause potential damage to important anatomical structures such as nerve roots, dura, ligamentum flavum and interspinous ligaments.
  • the above object is achieved by means of an extraforaminal approach including an access portal in the Fibrocartilago Intervertebralis between the anterior and posterior longitudinal ligaments for removing the affected intervertebral disc as well as for insertion of a total disc prosthesis.
  • the key element of the extraforaminal approach to the spinal disc is a path in front of the transverse processes (Processus Transversus).
  • the disc material is removed with a surgical device through a protection sleeve.
  • a protection sleeve This permits the advantage that the use of a protection sleeve during removing the disc material allows a better protection of the surrounding soft tissue.
  • the access portal is cut at a distance X>0 apart from the anterior longitudinal ligament and the posterior longitudinal ligament, therewith permitting the advantage that the anterior longitudinal ligament and the posterior longitudinal ligament remain intact in order to stabilize the treated segment of the vertebra.
  • the distance X amounts between 2 mm and 38 mm.
  • the width W of the access portal is between 8 mm and 36 mm.
  • the area A of the access portal is between 24 mm 2 and 684 mm 2 and the height is preferably between 3 and 19 mm.
  • the step of distracting of the vertebral bodies adjoining the disc space to be treated is performed through the protection sleeve.
  • the distraction of the vertebral bodies adjoining the disc space to be treated is performed by slightly bending a distractor in order to keep the view to the situs free for the surgeon.
  • the total disc replacement procedure is performed without dissecting the facet joints.
  • the total disc replacement procedure is performed without dissecting the transverse processes.
  • the access to the intervertebral space to be treated is essentially straight. This allows the advantage that due to the almost straight access the use of essentially straight instruments e.g. for cleaning the endplates of the adjacent vertebral bodies or other surgical actions is possible.
  • the incision is reduced to a tube.
  • the risk of damaging the neural structures is reduced by means of passing (not approaching) the spinal cord and locating, mobilising and marking the nerve root.
  • an intervertebral prosthesis which essentially comprises a first and a second prosthetic component each having an apposition surface disposed transversely to the central axis and apt for contacting the end plate of an adjoining vertebral body each. Furthermore, said first and second prosthetic components are connected by means of an articulation. When viewed parallel to said central axis said first and second prosthetic components have an elongated shape with a major axis and a transverse minor axis, whereby said central axis, major axis and transverse minor axis intersect each other and said central axis and transverse minor axis defining a middle plane.
  • Said first and second prosthetic component have a cross-sectional area orthogonal to said central axis which is essentially oval or elliptical and said cross-sectional area comprises at least a first and a second concavity lying on different side of the middle plane and on the same side of the major axis.
  • said cross-sectional area of said first and second prosthetic component is kidney shaped with an enlargement arranged essentially symmetrical to said the middle plane.
  • said at least two concavities have an essentially semi-elliptical or semi-oval shape.
  • said at least two convavities are disposed essentially symmetrical to said middle plane.
  • said first and second prosthetic component have a length H measured parallel to said major axis and wherein each of said at least two concavities has a width W measured parallel to said major axis, said width W amounting to between 15% and 35% of said length H.
  • said first and second prosthetic component have a maximum width B measured parallel to said transverse minor axis and wherein each of said at least two concavities has a depth T measured parallel to said transverse minor axis, said depth T amounting to between 5% and 25% of said maximum width B.
  • said cross-sectional area of said first and second prosthetic components has an essentially elliptical periphery with a smaller radius of curvature at the first subsidiary vertex than at the second subsidiary vertex of said periphery.
  • said first subsidiary vertex is on the same side of said major axis as said at least two concavities.
  • the ratio of the length H of the prosthetic components to the width B thereof is between 3:1 and 5:1.
  • said articulation is configured as a ball-and-socket joint comprising a spherical cap connected to one of the first and second prosthetic components and congruent to said spherical cap a spherical recess in the other of said first and second prosthetic components.
  • the intervertebral prosthesis is realised in two pieces, i.e. the spherical cap is made in one piece with one of the two prosthetic components.
  • the intervertebral prosthesis is realised in three pieces, so that the spherical cap forming the third piece is connectable with one of the two prosthetic components.
  • the advantage of this design is to be seen essentially in the fact that the plate and the spherical cap may be realised by using different materials, so that it is possible to achieve optimal sliding properties for the articular surfaces.
  • Preferred materials for the plates are titanium or a titanium alloy as well as PEEK or coated variants, and for the spherical cap highly crosslinked polyethylene (X-UHMWPE), an alloy of cobalt and chrome, or a ceramic material.
  • the intervertebral prosthesis is realised in at least three pieces and comprises an articular shell including the recess, whereby said articular shell is attachable to one of said first and second prosthetic components as a third piece.
  • the spherical cap and the articular shell consist of a material combination made of metal and plastic.
  • the advantages of this embodiment are that it is possible to use proven combinations of joint replacement materials such as, for example, highly crosslinked polyethylene (X-UHMWPE) and an alloy of cobalt and chrome. Further advantages are to be seen in the fact that low frictional forces are achievable for the relative displacement of the articular surfaces and that a compensation of axial impact loads can be achieved.
  • a ceramic-to-ceramic articulation is used.
  • the surfaces of the spherical cap and the recess are coated with titanium carbide or with amorphous carbon (ADLC) therewith permitting a substantial reduction of the coefficient of friction.
  • ADLC amorphous carbon
  • At least the spherical cap is made of a memory metal or of a material capable of swelling (e.g. hydrogels).
  • at least the spherical cap is made of a flowable, thermosetting material.
  • the monomers, comonomers, homopolymers, oligomers, or mixtures which contain such thermosetting, flowable substances may suitably be selected from the group of:
  • polyethylene glycols preferably polyethylene glycol(di)-acrylates
  • n-vinylpyrrolidones preferably vinyl alcohols
  • vinyls preferably vinyl alcohols
  • the polymers thus obtained may be widely varied as regards their elasticity.
  • the advantages of these designs are to be seen essentially in the fact that due to the reduced volume of the joint, the insertion of the intervertebral prosthesis becomes less invasive, the increased volume being best suited for achieving an optimal articular function.
  • first prosthetic component is selected from a first kit of at least M ⁇ 2 first prosthetic components and the second prosthetic component is selected from a second kit of at least N ⁇ 2 second prosthetic components.
  • Said first and second kit may comprise first and second prosthetic components being provided with different heights, articulation radii or locations of the centre of the respective radii, i.e. the center of rotation.
  • said first and second prosthetic component each comprise an intermediate surface, said first and second intermediate surfaces facing each other. At least the first or second intermediate surface is provided with at least one cavity with an undercut being located at the first or/and second lateral end of said first and second prosthetic components, said cavity with an undercut being apt for acceptance of an anchoring member of an implant holder.
