Description
    FIELD OF THE DISCLOSURE
  • [0001]
    The present disclosure relates generally to orthopedics and orthopedic surgery. More specifically, the present disclosure relates to devices used to support adjacent spinous processes.
  • BACKGROUND
  • [0002]
    In human anatomy, the spine is a generally flexible column that can take tensile and compressive loads. The spine also allows bending motion and provides a place of attachment for keels, muscles and ligaments. Generally, the spine is divided into three sections: the cervical spine, the thoracic spine and the lumbar spine. The sections of the spine are made up of individual bones called vertebrae. Also, the vertebrae are separated by intervertebral discs, which are situated between adjacent vertebrae.
  • [0003]
    The intervertebral discs function as shock absorbers and as joints. Further, the intervertebral discs can absorb the compressive and tensile loads to which the spinal column may be subjected. At the same time, the intervertebral discs can allow adjacent vertebral bodies to move relative to each other a limited amount, particularly during bending, or flexure, of the spine. Thus, the intervertebral discs are under constant muscular and/or gravitational pressure and generally, the intervertebral discs are the first parts of the lumbar spine to show signs of deterioration.
  • [0004]
    Facet joint degeneration is also common because the facet joints are in almost constant motion with the spine. In fact, facet joint degeneration and disc degeneration frequently occur together. Generally, although one may be the primary problem while the other is a secondary problem resulting from the altered mechanics of the spine, by the time surgical options are considered, both facet joint degeneration and disc degeneration typically have occurred. For example, the altered mechanics of the facet joints and/or intervertebral disc may cause spinal stenosis, degenerative spondylolisthesis, and degenerative scoliosis.

    More particularly, the interspinous process brace 400 can be bent, or otherwise folded, as shown in FIG. 6, in order to reduce an overall height of the interspinous process brace 400. Thereafter, the interspinous process brace 400 can be place between adjacent spinous processes and allowed to return to the straight configuration, shown in FIG. 7. Further, after the interspinous process brace 400 is allowed to return to the straight configuration, the locking sleeve 480 can be moved to the locked position, shown in FIG. 8, to prevent the interspinous process brace 400 from returning to the bent configuration.

Further, the superior spinous process bracket 454 can engage and support a superior spinous process 502. More specifically, the inferior spinous process engagement structure 422 can extend slightly into and engage the inferior spinous process 500. Also, the superior spinous process engagement structure 462 can extend slightly into and engage the superior spinous process 502. Accordingly, the spinous process engagement structures 422, 462 and the tethers 434, 474 can substantially prevent the interspinous process brace 400 from migrating with respect to the spinous processes 500, 502.

After the interspinous process brace 400 is installed, the distractor can be removed and the interspinous process brace 400 can support the superior spinous process 502 and the inferior spinous process 500 to substantially prevent the distance 510 between the superior spinous process 502 and the inferior spinous process 500 from returning to a pre-distraction value. Further, the interspinous process brace 400, when locked, as described herein, the interspinous process brace 400 can dynamically resist compressive loads, tensile loads, or a combination thereof. It may be desirable to allow the interspinous process brace 400 to bend or flex after it is installed. Therefore, the locking sleeve 480 may be omitted from the interspinous process brace 400.

Thereafter, the interspinous process brace 1800 can be place between adjacent spinous processes and returned to the straight configuration, shown in FIG. 19. Further, after the interspinous process brace 1800 is returned to the straight configuration, the locking pin 1808 can be installed within the central hinge 1806, to prevent the interspinous process brace 1800 from returning to the bent configuration.
  • [0105]
    In a particular embodiment, when the interspinous process brace 1800 is properly installed between a superior vertebra and an inferior vertebra, shown in FIG. 18, the inferior spinous process bracket 1814 can engage and support an inferior spinous process 1900. Further, the superior spinous process bracket 1854 can engage and support a superior spinous process 1902. More specifically, the inferior spinous process engagement structure 1822 can extend slightly into and engage the inferior spinous process 1900. Also, the superior spinous process engagement structure 1862 can extend slightly into and engage the superior spinous process 1902. Accordingly, the spinous process engagement structures 1822, 1862 and the tethers 1834, 1874 can substantially prevent the interspinous process brace 1800 from migrating with respect to the spinous processes 1900, 1902.
  • [0106]
    Also, in a particular embodiment, a distractor can be used to increase a distance 1910 between the superior spinous process 1902 and the inferior spinous process 1900 and the interspinous process brace 1800 can be installed to support the superior spinous process 1902 and the inferior spinous process 1900. After the interspinous process brace 1800 is installed, the distractor can be removed and the interspinous process brace 1800 can support the superior spinous process 1902 and the inferior spinous process 1900 to substantially prevent the distance 1910 between the superior spinous process 1902 and the inferior spinous process 1900 from returning to a pre-distraction value.

    Description of a Method of Treating a Spine
  • [0107]
    Referring to FIG. 21, a method of treating a spine is shown and commences at block 2100. At block 2100, a patient can be secured on an operating table. Depending on the surgical approach to be used, the patient can be secured in a prone position for a posterior approach, a supine position for an anterior approach, a lateral decubitus position for a lateral approach, or another position well known in the art. At block 2102, the spine can be exposed in order to expose adjacent spinous processes. Further, at block 2104, a surgical retractor system can be installed to keep a surgical field open.
  • [0108]
    Moving to block 2106, a superior vertebra and inferior vertebra can be distracted. In a particular embodiment, the superior vertebra and inferior vertebra can be distracted using a distractor. At block 2108, a distance between the adjacent spinous processes can be measured. Thereafter, at block 2110 it is determined whether the distraction is correct, e.g., has the superior vertebra and inferior vertebral been distracted such that a distance between the adjacent spinous processes has reached a value that a surgeon has deemed therapeutic. For example, the superior vertebra and inferior vertebra can be distracted in order to reduce or obviate impingement on a nerve root.
  • [0109]
    If the distraction is not correct, the method can return to block 2106 and the superior vertebra and inferior vertebra can be further distracted. Conversely, if the distraction is correct, the method can move to block 2112 and an interspinous process brace can be moved to a bent configuration. The interspinous process brace can be an interspinous process brace in accordance with one or more embodiments described herein. At block 2114, the interspinous process brace can be installed between the adjacent spinous processes. Further, at block 2116, the interspinous process brace can be allowed to return to the straight configuration.
  • [0110]
    Moving to decision step 2118, it can be determined whether to lock the interspinous process brace. In a particular embodiment, this determination can be based on any degradation of the particular vertebral joint that is being repair, any degradation of the surrounding facet joints, any degradation of the adjacent processes, or a combination thereof. If it is determined to lock the interspinous process brace, the method can move to block 2120 and the interspinous process brace can be locked. For example, one or more locking sleeves on the interspinous process brace can be moved to a locked position to prevent the interspinous process brace from bending. Alternatively, one or more locking plates can be installed in the interspinous process brace to prevent the interspinous process brace from bending. From block 2120, the method proceeds to block 2122.
  • [0111]
    It is noted that multiple braces can be supplied in kit form for field use with each brace corresponding to a different distraction distance, such that the proper post distraction positioning of the processes can be maintained. Alternatively or in addition, the kit can contain locking pins and/or discrete, separable locking plates if the brace configuration receives such plates.
  • [0112]
    Returning to decision step 2118, if it is determined not to lock the interspinous process brace, the method can move directly to block 2122 and the surgical area can be irrigated. At block 2124, a distractor can be removed. Also, at block 2126, the retractor system can be removed. Further, at block 2128, the surgical wound can be closed. The surgical wound can be closed by simply allowing the patient's skin to close due to the elasticity of the skin. Alternatively, the surgical wound can be closed using sutures, surgical staples, or any other suitable surgical technique well known in the art. At block 2130, postoperative care can be initiated. The method can end at state 2132.
  • [0113]
    In another embodiment, an interspinous process brace according to one or more of the embodiments described herein can be used to distract a superior spinous process and an inferior spinous process. For example, the interspinous process brace can be bent and placed between a superior spinous process and inferior spinous process. Thereafter, the interspinous process brace can be straightened. As the interspinous process brace is straightened, it can distract the superior spinous process and the inferior spinous process. After the spinous processes are distracted, the interspinous process brace can remain in place.
  • [0114]
    Alternatively, the interspinous process brace can be used to distract the spinous processes and an implant can be installed between a superior vertebra and an inferior vertebra. After the implant is installed between the superior vertebra and the inferior vertebra, the interspinous process brace can be returned to the bent configuration and removed. In a particular embodiment, the implant can be a one-piece intervertebral prosthetic disc, a two-piece intervertebral prosthetic disc, a three-piece intervertebral prosthetic disc, a solid nucleus implant, an inflatable nucleus implant, an expandable nucleus implant, a fusion cage, or some other similar device.
  • CONCLUSION
  • [0115]
    With the configuration of structure described above, the interspinous process brace provides a device that can be used to treat a spine and substantially alleviate or minimize one or more symptoms associated with disc degeneration, facet joint degeneration, or a combination thereof. For example, the interspinous process brace can installed between adjacent spinous processes in order to support the spinous processes and maintain them at or near a predetermined distance there between.
