Definitions

  • the present invention generally relates to bone fixation systems.
  • An embodiment of the invention relates to a compression plate for a spinal fixation system.
  • the compression plate may be installed using an anterior procedure.
  • the compression plate may be used in conjunction with one or more spinal implants that fuse vertebrae together.
  • An intervertebral disc may be subject to degeneration caused by trauma, disease, and/or aging.
  • a degenerated intervertebral disc may have to be partially or fully removed from a spinal column. Partial or full removal of an intervertebral disc may destabilize a spinal column. Destabilization of a spinal column may alter a natural separation distance between adjacent vertebrae. Maintaining a natural separation distance between vertebrae may help prevent pressure from being applied to nerves that pass between vertebral bodies. Excessive pressure applied to the nerves may cause pain and/or nerve damage.
  • a spinal implant may be inserted in a space created by removal or partial removal of an intervertebral disc between adjacent vertebrae. A spinal implant may maintain the height of the spine and restore stability to the spine. Intervertebral bone growth may fuse the implant to adjacent vertebrae.
  • a spinal implant may be inserted during a spinal fixation procedure using an anterior, lateral, or posterior spinal approach.
  • an anterior approach may result in an easier approach, less muscle damage, less tissue damage, and/or less bone removal than other approaches.
  • a discectomy may be performed to remove or partially remove a defective and/or damaged intervertebral disc.
  • a discectomy creates a disc space for a spinal implant.
  • a spinal implant may be inserted into the disc space.
  • One or more spinal implants may be inserted between a pair of vertebrae.
  • Spinal implants may be inserted into disc spaces prepared between more than one pair of vertebrae during a spinal fusion procedure.
  • a spinal plate may be coupled to vertebrae after insertion of one or more spinal implants.
  • a spinal plate may stabilize the vertebrae and inhibit backout of the spinal implant from between vertebrae.
  • a spinal plate may share a compressive load applied to one or more spinal implants inserted between vertebrae.
  • Fasteners e.g., bone screws
  • Spinal plates may stabilize sections of cervical spine and/or sections of lumbar spine.
  • Fastening systems may attach a spinal plate to vertebrae without allowing fasteners of the fastening systems to back out from the vertebrae.
  • a fastening system may include a fastener and a retainer. The retainer may be positioned in an opening of the spinal plate. Backout of fasteners from the spinal plate may be inhibited without immovably fixing the fasteners or the retainers to the spinal plate.
  • U.S. Pat. No. 6,331,179 to Freid et al. and U.S. Pat. No. 6,454,679 to Wagner et al. both of which are incorporated by reference as if fully set forth herein, describe bone plate systems including fasteners and retainers.
  • U.S. Pat. No. 6,328,738 to Suddaby which is incorporated by reference as if fully set forth herein, describes an anterior cervical fusion compression plate and screw guide.
  • the anterior cervical fusion compression plate has a pair of slideable inserts. Each insert is situated in a recess at an end of the plate to allow vertebral compression.
  • a pliers-like tool is used to move the inserts toward the center of the plate.
  • central screws are tightened to fix the position of the inserts. Lateral screws may be driven into the inserts to anchor the vertebrae to the plate.
  • An adjustable-length spinal compression plate may be used to stabilize vertebrae and/or apply a compressive load to a spinal implant positioned in a disc space between a pair of vertebrae.
  • One or more fasteners may couple a first plate to a vertebra above a spinal implant.
  • One or more fasteners may couple a second plate to a vertebra below a spinal implant.
  • the first plate may be coupled to the second plate so that the first plate is able to move toward and/or away from the second plate.
  • motion of the first plate relative to the second plate may be restricted to allow only unidirectional motion (i.e., only compression of the spinal compression plate) during use.
  • Movement of the first plate toward the second plate may allow the spinal plate system to accommodate settling and/or subsidence of the vertebrae while maintaining a compressive load on the spinal implant.
  • three or more plates may be coupled together to form an adjustable-length spinal compression plate that spans two or more vertebral levels.
  • Plates of a spinal plate system may be curved to maintain a lordotic curvature of a human spine during compression of the spinal plate system. Plates may be provided with preformed curvatures to accommodate lordotic and/or radial vertebrae curvature. In some embodiments, a plate of a spinal compression plate may have one or more grooves to facilitate bending of the spinal compression plate to achieve a desired lordotic curvature.
  • Plates of a spinal plate system may be available in various sizes. The size of a plate utilized may depend on the number of vertebrae to be immobilized and/or the size of a patient. Plates may have an anterior side, a posterior side, and two ends. A spinal plate system may be coupled to vertebrae using one or more openings through the plates. Openings may be located at various positions along the plate. A spinal plate system may have a center opening. An opening in a spinal compression plate may have a regular or an irregular shape. An opening in a spinal compression plate may be substantially circular or elongated. In some embodiments, a portion of a plate may form a wall of an opening. Alternatively, a liner, a cover, and/or a coating may form a wall of an opening.
  • Plates of a spinal plate system may be coupled together using coupling mechanisms to form a spinal compression plate.
  • a coupling mechanism may include one or more coupling members and one or more coupling cavities.
  • a coupling mechanism may include mating slots and extensions that allow movement of a plate of a spinal compression plate relative to another plate of the spinal compression plate.
  • a portion of a first plate may overlay a portion of a second plate.
  • one or more mating surfaces of plates of a spinal compression plate may have friction texturing. Plates may be coupled so that the plates can move in a longitudinal direction during use.
  • a spinal compression plate may be compressed along a longitudinal axis during use. Movement of the plates may be restricted by the size of a coupling cavity.
  • a spinal compression plate may compress longitudinally during use; however, the spinal compression plate may be inhibited from expanding longitudinally during use.
  • a movement mechanism may inhibit expansion during use.
  • a movement mechanism may include one or more protrusions on the spinal compression plate. Protrusions may be positioned on surfaces of the plates that normally contact each other. Some embodiments include a protrusion on a first plate that engages one or more protrusions (e.g., serrations) on a second plate to maintain a distance between the vertebrae after compression. In some embodiments, at least a portion of a serrated surface of a movement mechanism may be curved to increase an area of the movement mechanism and thus enhance stability of a spinal compression plate.
  • a probe may be inserted into an opening in a spinal compression plate to release a movement mechanism (e.g., a ratcheting system) to allow expansion of the spinal compression plate.
  • a movement mechanism e.g., a ratcheting system
  • an opening in a spinal compression plate may be used for monitoring the amount of compression of a spinal compression plate in a patient after insertion of the spinal compression plate.
  • a portion of a first plate may extend into an opening in the second plate. The position of the portion of the first plate relative to the opening in the second plate may be monitored using x-ray imaging to determine the amount of compression of the spinal compression plate.
  • Some spinal plate systems may include an engagement mechanism that inhibits separation of a first plate from a second plate of the spinal compression plate.
  • An engagement mechanism may inhibit separation of the plates while allowing the plates to adjust for lordotic alignment as the spinal compression plate is compressed.
  • an engagement mechanism may include a protruding member of a first plate that engages serrations in a second plate.
  • a spinal compression plate may freely compress and expand unencumbered by a movement mechanism.
  • a first plate may not include protrusions to engage protrusions on a second plate.
  • a second plate may not have protrusions to engage protrusions on a first plate. Compression and expansion of a spinal compression plate may allow the plate to accommodate natural vertebral movement.
  • a coupling cavity may restrict the range of motion of a first plate relative to a second plate of a spinal compression plate and/or inhibit separation of the first plate from the second plate.
  • portions of the first plate that engage the second plate and/or portions of the second plate that engage the first plate may be textured to alter frictional properties of the first plate relative to the second plate.
  • a spacer may set an initial separation between a first plate and a second plate of a spinal compression plate.
  • the spacer may have an insertion end, an alignment portion, and a guidepost.
  • the spacer may couple to a spinal compression plate.
  • a fastener guide may be coupled to a guidepost of the spacer.
  • a positioner may be used to help position a spinal compression plate in a desired location in a patient.
  • the position may have an engagement end, and alignment portion, and a guidepost.
  • a fastener guide may be coupled to a guidepost of a positioner.
  • a plate insertion instrument may couple with a guide opening of a spinal compression plate to allow positioning of the spinal compression plate within a patient.
  • an engagement end of the plate insertion instrument may be press-fit into the guide opening of the spinal compression plate.
  • a plate insertion instrument may be attached to a portion of a spacer or positioner that is coupled to the spinal compression plate.
  • Spinal plate systems may be utilized in conjunction with implants and/or other medical devices. In certain instances, it may be beneficial for a spinal plate system to share at least some of the load experienced by a spinal plate system with a medical device. Bone growth may be increased around and through an implant that is carrying a load. Therefore, spinal plate systems may be designed to share a portion of the load from surrounding vertebrae with a spinal implant positioned between the vertebrae.
  • a portion of a plate forms a wall of an opening.
  • a recess may be positioned in a wall to engage a retainer that inhibits removal of a fastener from a plate.
  • a recess may be biased to allow the fastener to enter a vertebra at a desired angle. Allowing a fastener to enter a spinal compression plate at an angle may facilitate establishment of a secure connection between the spinal compression plate and the vertebra.
  • a recess may have a larger height than a height of the portion of a retainer that fits within the recess. The greater height of the recess may allow for some angulation adjustment of a fastener positioned through the retainer into a vertebra.
  • openings on a superior end of a spinal compression plate may allow for greater angulation of fasteners than openings on an inferior end of the spinal compression plate.
  • a portion of an opening may have a spherically shaped contour to permit a fastener to be “obliquely angulated” relative to a plate.
  • an “obliquely angulated” fastener refers to a fastener that may be positioned at a wide range of angles relative to a plate. In some embodiments, a range of angles may be from 0° to about 20° from an axis perpendicular to a plate.
  • a fastener may be secured in a plate using a retainer, such as a ring.
  • a retainer may be positioned in an opening of a spinal compression plate.
  • the opening of the spinal compression plate may be elongated to allow longitudinal movement of the retainer in the opening.
