Definitions

  • the present invention relates to a spinal osteosynthesis instrumentation adapted to stabilize at least a part of the spine.
  • spinal osteosynthesis devices usually comprise vertebral rods which are rigid and bent so as to adapt them to the anatomy of the considered spinal segment, bone anchorage means formed by screws or pedicle hooks, and connecting elements between these anchorage means and the rods. Sometimes the rods are interconnected by transverse connecting devices.
  • a spinal stabilization system that may be more readily shaped to conform to desired contours in the sagittal and frontal planes.
  • multidimensional shaping may be easily performed and still provide a rigid stabilization construct once the desired shape is attained.
  • the present invention meets these needs and has other significant advantages and benefits.
  • a spinal osteosynthesis apparatus in one form of the present invention, includes a first module having a ball and a second module having a socket receiving the ball therein. Also included is a clamping member element disposed on the second module that is made of a shape memory material. The clamping member permits relative motion of the ball in the socket when at a first temperature to correspondingly position the first module relative to the second module. Further, the clamping member clamps the ball within the socket to provide a generally rigid assembly of the first module and the second module when at a second temperature greater than the first temperature.
  • This form permits contouring the modules to a desired shape while the clamping member is at the first temperature and raising temperature to the second temperature to retain the shape.
  • the first temperature is less than about 20 degrees Celsius and the second temperature is greater than about 20 degrees Celsius. More preferably, the second temperature is about the nominal body temperature of a human patient.
  • a spinal osteosynthesis apparatus in an additional form of the present invention, includes a first module having a ball at one end and a second module defining a socket receiving the ball therein.
  • the second module is elastically deformable to receive the ball in the socket by a clipping action and retain the ball in the socket.
  • the second module is configured to permit positioning of the first module relative to the second module while the ball is retained in the socket and to selectively fix the ball in the socket to provide a generally rigid assembly.
  • At least one of the first and second modules carries a bone anchorage element configured to engage a patient's spine.
  • a spinal osteosynthesis apparatus in a further form of the present invention, includes a first chain of a first number of articulated modules connected together by a corresponding first number of ball-and-socket joints.
  • a first one of the first modules includes a first hook configured to engage a patient's spine, and a second one of the first modules defines a first opening configured to receive a first threaded fastener for engaging the patient's spine.
  • the apparatus also includes a second chain of a second number of articulated modules connected together by a corresponding second number of ball-and-socket joints.
  • a first one of the second modules includes a second hook configured to engage the patient's spine and a second one of the second modules defines a second opening configured to receive a second threaded fastener for engaging the patient's spine.
  • a third one of the first modules is transversely connected to a third one of the second modules by a ball-and-socket joint laterally disposed between the first and second chains.
  • the spinal osteosynthesis instrumentation comprises two independent modules, means for ensuring a retaining connection between the modules enabling them to be oriented in all directions, means for connecting the modules to a bone, and means for immobilizing the modules relative to each other, the instrumentation permitting effecting a correction and then a final immobilization.
  • the instrumentation comprises at least two modules provided with bone anchorage elements articulated together by a male-female spherical connection permitting a relative orientation of the modules in all directions, and means for rigidity ing the assembly of the modules in the desired orientation so as to adapt the assembly to the anatomy of the considered spinal segment.
  • the instrumentation according to the invention thus constitutes an assembly of a plurality of modules articulated together in pairs, which permits arranging them to conform in a multidirectional manner to the spine of the patient in the manner of an articulated chain, with no force exerted on the spine and with the assembly exactly conforming to the anatomy of the latter. Once this chain has been put into shape in the desired position, it can be maintained rigidly in this configuration by suitable means.
  • some sections of the articulated chain may be rendered rigid while others remain freely articulated to permit corrections in situ, which is not generally available when bent rigid rods are employed. In this way, corrections can be effected and then the assembly can be finally immobilized.
  • the bone anchorage may be ensured by any adapted means such as: threads, cables, ligaments, cages, rods, curved or flat plates, screws.
  • each module comprises a body in which is formed a spherical socket opening onto one end of the body for receiving a spherical head of an adjacent module, this head being maintained in its socket by a clipping action, thereby forming a ball joint.
  • One or more of the modules of the instrumentation may comprise a body and a spherical articulation head in one piece with the body, the latter having for example a substantially cylindrical outer surface which imparts to the module the appearance of a pawn or a kind of skittle.
  • One or more modules may be equipped laterally with a bone anchorage hooking strip, or a plate receiving a bone screw.
  • rigidifying means for the connections between the modules comprise rings composed of a shape memory alloy.
  • the rings are adapted to surround the corresponding bodies in the region of their sockets for articulation to the neighboring modules, and exert on the walls of the sockets and the spherical head inserted therein a clamping action at the temperature of the body of the patient by a shrinkage of the rings, these rings expanding at a lower temperature.
  • These clamping rings therefore benefit from the characteristics of the shape memory of some alloys which, at low temperature, for example at 10 to 20°C, are relatively soft and in the expanded state, and at a higher temperature, for example at the temperature of the human body (37°C), become shrunk and consequently exert a very high clamping force on the part they surround.
  • the instrumentation according to the invention thus permits replacing the vertebral rods employed up to the present time for the staying of the spine by such articulated assemblies.
  • This instrumentation over rigid rods is the capability of very closely conforming to the anatomy of the spinal segment rapidly and with minimum difficulty.
  • This segment may be for example a cervical region, a thoracic region, a lumbar region, or a sacral region.
  • one object of the present invention is to provide a spinal osteosynthesis instrumentation that may be readily conformed to a desired shape.
  • Another object is to provide a means of making a chain of articulated modules rigid once a desired shape of the modules is attained.
  • Yet another object of the present invention is to provide a spinal instrumentation system with articulated modules adapted for engagement to a patient's spine by hooks and threaded fasteners.

  • each module 1 , 2 comprises a body 3, having end 3a in which is formed a spherical socket 5.
  • Socket 5 opens onto end 3a of body 3.
  • each body 3 is extended by a spherical head or ball 8 attached by neck 9.
  • Each body 3 has a central portion 3c generally having a cylindrical shape and is disposed between the opposing ends 3a, 3b.
  • body 3 comprising socket 5, head 8, and neck 9 is integrally formed as one piece.
  • Formed in the opposing walls 5a, 5b of each socket 5 are at least two diametrally opposed longitudinal slots 7 which impart to walls 5a, 5b a certain flexibility enabling them to be spread apart when ball 8 of another module is inserted in socket 5.
  • Slots 7 generally extend further along the longitude of body 3 than socket 5 and terminate in a generally circular opening 7a adjacent the innermost margin of socket 5.
  • each spherical socket 5 is advantageously provided with a respective annular chamfer 12 which is outwardly divergent so as to define a point of increased resistance to the passage of the ball 8 which, in association with the flexibility of walls 5a, 5b of socket 5, permits the insertion and the maintenance of ball 8 by a clipping action in socket 5.
  • the ball 8 consequently forms the ball of a ball-and-socket joint 13 between the two modules 1, 2.
  • the instrumentation further comprises means for rigidifying or fixing the connections between the modules 1, 2.
  • these means comprise clamping members in the form of rings 14 composed of an alloy having a memory of its shape that is adapted to surround the corresponding bodies 3 of the modules 1, 2 in the region of their spherical sockets 5.
  • Each clamping ring 14 is at least partly disposed in a corresponding groove 15 provided on the outer periphery of walls 5a, 5b of socket 5.
  • the alloy making up each ring 14 has the feature called "shape memory", i.e. the alloy has the characteristics of being deformable by exertion of small forces when it is at low temperature, for example at room temperature (about 10 to 20°C), and of shrinking and creating a clamping action on the surface with which the ring 14 is in contact when the temperature of the ring rises to the temperature of the body of the patient (about 37°C).
  • each ring 14 has at this temperature a powerful clamping action on the walls of the socket 5, and consequently on the ball 8 disposed therein, and in this way firmly maintains the ball 8 in the chosen angular orientation relative to the socket 5 in which it has been placed.
  • the alloy having a shape memory may be of a nickel-titanium alloy, with the material of the bodies 3 then being titanium.
  • the bodies 3 are in the form of small pawn-like pins or skittles inserted one inside the other.
  • bodies 3 each generally have the shape of a bowling pin.
  • An articulated chain of modules 1, 2 may be advantageously substituted for the vertebral rods used up to present time in spinal osteosynthesis devices.
  • a corresponding number of ball- and-socket joints 13 connect the modules 1,2 of the chain together.
  • Modules 1 , 2 may be adapted to provide means for fixing them to the vertebral bodies of the spine, cranial bone, or other bone; and incorporated into an articulated module chain, such as chain 21a of instrumentation assembly 20a shown in Figure 2 or chain 21b of instrumentation assembly 20b shown in Figure 3.
  • chains 21a, 21b include spinal modules 16 whose bodies and balls are identical to those of the modules 1 and 2 but are provided with lateral means for permitting a bone anchorage.
  • This lateral means for each module 16 includes a lateral ring 18 which may receive a threaded fastener, such as anchorage screw 19 ( Figure 3) or a bolt/nut assembly (not shown), and may be provided on one of its faces with radial splines 21 ( Figure 3) for cooperation with a plate which is also splined (not shown). Details concerning slots 7, clamping rings 14, and grooves 15 are not shown in Figure 2 to preserve clarity.
  • a threaded fastener such as anchorage screw 19 ( Figure 3) or a bolt/nut assembly (not shown)
  • chains 21a, 21b each include module 17.
  • Module 17 includes a lateral hook 22 in which an opening 23 is formed for the passage of a screw (not shown).
  • module 24 is provided with another form of hook designated by reference number 25.
  • One or more modules 26 may also be included, as shown in assembly 20a.
  • Module 26 has plate 26a provided with openings 27 for the passage of threaded bone anchorage fasteners such as screws or a bolt/nut arrangement. Plate 26a is extended by body portion 26b.
  • Body portion 26b defines a spherical socket 5 in which a ball 8 of the neighboring module, for example a module 2 ( Figure 2), may be inserted to form a corresponding ball-and-socket joint 13.
  • the number and location of the bone engaging module types in a given chain, such as modules 16, 17, 24, 26, depends on the region of the spine in which it is to be positioned.
  • each module 1, 2, 16, 17, 24, 26 extends over a length which may be either the intervertebral distance in the corresponding region of the spine, a multiple of this distance, or any other length.
  • assembly 20b comprises an articulated chain 21b with module 28.

  • modules 1, 2, 16, 17, 24, 26 correspond to a desired intervertebral distance and module 28 corresponds to generally twice this distance.
  • the module 29 of Figure 4 has a massive body 31 in which a tapped hole 32 is formed for the passage of a screw (not shown). Hole 32 is laterally positioned relative to socket 5 and ball 8 of module 29.
  • Module 29 may be incorporated into an articulated chain, such as chain 21a or 21b either in place of or in addition to existing modules; or into any other chain configuration as would occur to those skilled in the art.
  • a chain terminates with at least one module 33 (Figure 5 and 6).
  • Module 33 has bent plate 34 provided with a plurality of opemngs 35, 36 for the passage of screws or other threaded fasteners (not shown) and completed at one of its ends by a body 37 similar to the bodies 3, but devoid of ball 8.
  • the body 37 is in fact connected to the plate 34 by any suitable means known to those skilled in the art to provide one integral piece.
  • module 33 has a curvature adapted to the shape of the occiput or the sacrum.
  • module 33 is shown connected to module 2 to form assembly 30.

  • the occipital and sacral plates, such as 33, are more easily adaptable to the anatomy of the patient than a conventional plate having pre-machined openings in respect of which the position of the screws is imposed. Indeed, the articulation bodies 37, of these plates allow an angulation which considerably increases their flexibility of adaptation to the optimal fastening position.
  • FIG. 7 The variant of Figure 7 is a module 41 provided with a lateral ball 42 permitting a transverse articulation with another module, such as module 43 of Figure 8.

Further one or more such chains may be interconnected to provide a desired instrumentation as would occur to those skilled in the art.
  • the instrumentation according to the invention is extremely flexible since it is easily adaptable to the anatomy of all the regions of the spine. In this way, the difficult and complex operations for bending the vertebral rods of the instrumentations of the prior art are avoided, with the use of a smaller number of parts. Further, the connections between the modules by means of clamping rings having a shape memory avoid the necessity to effect setting or forming-over operations. Another important advantage of this instrumentation resides in the fact that, in the event of fracture of a module, the overall assembly with the spine remains, which is essential for the safety of the patient.
