Definitions

  • the present disclosure relates generally to orthopedics and orthopedic surgery. More specifically, the present disclosure relates to devices used to support adjacent spinous processes.
  • the spine 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.
  • 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.
  • 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.

Description

    FIELD OF THE DISCLOSURE
  • 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
  • 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.
  • 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.
  • 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.

  • Description of Relevant Anatomy
  • Referring initially to FIG. 1, a portion of a vertebral column, designated 100, is shown. As depicted, the vertebral column 100 includes a lumbar region 102, a sacral region 104, and a coccygeal region 106. As is known in the art, the vertebral column 100 also includes a cervical region and a thoracic region. For clarity and ease of discussion, the cervical region and the thoracic region are not illustrated.
  • As shown in FIG. 1, the lumbar region 102 includes a first lumbar vertebra 108, a second lumbar vertebra 110, a third lumbar vertebra 112, a fourth lumbar vertebra 114, and a fifth lumbar vertebra 116. The sacral region 104 includes a sacrum 118. Further, the coccygeal region 106 includes a coccyx 120.
  • As depicted in FIG. 1, a first intervertebral lumbar disc 122 is disposed between the first lumbar vertebra 108 and the second lumbar vertebra 110. A second intervertebral lumbar disc 124 is disposed between the second lumbar vertebra 110 and the third lumbar vertebra 112. A third intervertebral lumbar disc 126 is disposed between the third lumbar vertebra 112 and the fourth lumbar vertebra 114. Further, a fourth intervertebral lumbar disc 128 is disposed between the fourth lumbar vertebra 114 and the fifth lumbar vertebra 116. Additionally, a fifth intervertebral lumbar disc 130 is disposed between the fifth lumbar vertebra 116 and the sacrum 118.
  • In a particular embodiment, if one of the intervertebral lumbar discs 122, 124, 126, 128, 130 is diseased, degenerated, damaged, or otherwise in need of repair, treatment of that intervertebral lumbar disc 122, 124, 126, 128, 130 can be effected in accordance with one or more of the embodiments described herein.
  • FIG. 2 depicts a detailed lateral view of two adjacent vertebrae, e.g., two of the lumbar vertebra 108, 110, 112, 114, 116 shown in FIG. 1. FIG. 2 illustrates a superior vertebra 200 and an inferior vertebra 202. As shown, each vertebra 200, 202 includes a vertebral body 204, a superior articular process 206, a transverse process 208, a spinous process 210 and an inferior articular process 212. FIG. 2 further depicts an intervertebral disc 216 between the superior vertebra 200 and the inferior vertebra 202.
  • Referring to FIG. 3, a vertebra, e.g., the inferior vertebra 202 (FIG. 2), is illustrated. As shown, the vertebral body 204 of the inferior vertebra 202 includes a cortical rim 302 composed of cortical bone. Also, the vertebral body 204 includes cancellous bone 304 within the cortical rim 302. The cortical rim 302 is often referred to as the apophyseal rim or apophyseal ring. Further, the cancellous bone 304 is softer than the cortical bone of the cortical rim 302.
  • As illustrated in FIG. 3, the inferior vertebra 202 further includes a first pedicle 306, a second pedicle 308, a first lamina 310, and a second lamina 312. Further, a vertebral foramen 314 is established within the inferior vertebra 202. A spinal cord 316 passes through the vertebral foramen 314. Moreover, a first nerve root 318 and a second nerve root 320 extend from the spinal cord 316.
  • It is well known in the art that the vertebrae that make up the vertebral column have slightly different appearances as they range from the cervical region to the lumbar region of the vertebral column. However, all of the vertebrae, except the first and second cervical vertebrae, have the same basic structures, e.g., those structures described above in conjunction with FIG. 2 and FIG. 3. The first and second cervical vertebrae are structurally different than the rest of the vertebrae in order to support a skull.
  • Description of a First Embodiment of a Multi-Chamber Expandable Interspinous Process Brace
  • Referring to FIG. 4 through FIG. 6, a first embodiment of a multi-chamber expandable interspinous process brace is shown and is generally designated 400. As shown, the multi-chamber expandable interspinous process brace 400 includes an interior chamber 402 and an exterior chamber 404.
  • In a particular embodiment, the interior chamber 402 can be generally elliptical. Alternatively, the interior chamber 402 can be generally spherical, generally pyramidal, generally conical, generally frustal, generally cubic, generally polyhedral, or a combination thereof. The exterior chamber 404 can be provided in a shape that can generally engage and/or stabilize at least one spinous process, such as, for example, the spinous processes of two adjacent vertebrae. In a particular embodiment, the exterior chamber 404 can be generally H-shaped.
  • Further, in a particular embodiment, the chambers 402, 404 can be made from one or more expandable biocompatible materials. For example, the materials can be silicones, polyurethanes, polycarbonate urethanes, polyethylene terephthalate, silicone copolymers, polyolefins, or any combination thereof. Also, the chambers 402, 404 can be non-porous or micro-porous, e.g., for venting purposes.
  • As shown in FIG. 4, the interior chamber 402 can include a first injection tube 406. Further, the exterior chamber 404 can include a second injection tube 408. The injection tubes 406, 408 can be used to provide an injectable biocompatible material to the chambers 402, 404. In a particular embodiment, each of the interior chamber 402 and the exterior chamber 404 of the multi-chamber expandable interspinous process brace 400 can be expanded from a respective deflated configuration, shown in FIG. 4, to one of a plurality of inflated configurations, shown in FIG. 5, up to a maximum inflated configuration. Further, after the interior chamber 402 and the exterior chamber 404 are inflated, or otherwise expanded, the injection tubes 406, 408 can be removed, as depicted in FIG. 6.
  • In a particular embodiment, the multi-chamber expandable interspinous process brace 400 can include a first self-sealing valve (not shown) within the interior chamber 402, e.g., adjacent to the first injection tube 406. Moreover, the multi-chamber expandable interspinous process brace 400 can include a second self-sealing valve (not shown) within the exterior chamber 404, e.g., adjacent to the second injection tube 408. The self-sealing valves can prevent the chambers 402, 404 from leaking material after the chambers 402, 404 are inflated and the injection tubes 406, 408 are removed.
  • As illustrated in FIG. 4 through FIG. 6, the exterior chamber 404 can include a superior spinous process pocket 410 and an inferior spinous process pocket 412. Further, a superior spinous process engagement structure 420 can extend from the exterior chamber 404 within the superior spinous process pocket 410. Also, an inferior spinous process engagement structure 422 can extend from the exterior chamber 404 within the inferior spinous process pocket 410. In a particular embodiment, each of the spinous process engagement structures 420, 422 can be one or more spikes, one or more teeth, a combination thereof, or some other structure configured to engage a spinous process.
  • FIG. 4 through FIG. 6 indicate that the multi-chamber expandable interspinous process brace 400 can be implanted between a superior spinous process 500 and an inferior spinous process 502. In a particular embodiment, the chambers 402, 404 can be inflated so the exterior chamber 404 engages the spinous processes 500, 502. In a particular embodiment, when the multi-chamber expandable interspinous process brace 400 is properly installed and inflated between the superior spinous process 500 and the inferior spinous process 502, the superior spinous process pocket 410 can engage and support the superior spinous process 500. Further, the inferior spinous process pocket 412 can engage and support an inferior spinous process 502.
  • More specifically, the superior spinous process engagement structure 420 can extend slightly into and engage the superior spinous process 500. Also, the inferior spinous process engagement structure 422 can extend slightly into and engage the inferior spinous process 502. Accordingly, the spinous process engagement structures 420, 422, the spinous process pockets 410, 412, or a combination thereof can substantially prevent the multi-chamber expandable interspinous process brace 400 from migrating with respect to the spinous processes 500, 502.
  • Also, in a particular embodiment, the multi-chamber expandable interspinous process brace 400 can be movable between a deflated configuration, shown in FIG. 4, and one or more inflated configurations, shown in FIG. 5 and FIG. 6. In the deflated configuration, a distance 510 between the superior spinous process pocket 410 and the inferior spinous process pocket 412 can be at a minimum. However, as one or more materials are injected into the chambers 402, 404, the distance 510 between the superior spinous process pocket 410 and the inferior spinous process pocket 412 can increase.
  • Accordingly, the multi-chamber expandable interspinous process brace 400 can be installed between a superior spinous process 500 and an inferior spinous process 502. Further, the multi-chamber expandable interspinous process brace 400 can be expanded, e.g., by injecting one or more materials into the chambers 402, 404, in order to increase the distance between the superior spinous process 500 and the inferior spinous process 502.
  • Alternatively, a distractor can be used to increase the distance between the superior spinous process 500 and the inferior spinous process 502 and the multi-chamber expandable interspinous process brace 400 can be expanded to support the superior spinous process 500 and the inferior spinous process 502. After the multi-chamber expandable interspinous process brace 400 is expanded accordingly, the distractor can be removed and the multi-chamber expandable interspinous process brace 400 can support the superior spinous process 500 and the inferior spinous process 502 to substantially prevent the distance between the superior spinous process 502 and the inferior spinous process 500 from returning to a pre-distraction value.

Further, the polyolefin materials can include polypropylenes, polyethylenes, halogenated polyolefins, or flouropolyolefins.
  • The hydrogels can include polyacrylamide (PAAM), poly-N-isopropylacrylamine (PNIPAM), polyvinyl methylether (PVM), polyvinyl alcohol (PVA), polyethyl hydroxyethyl cellulose, poly (2-ethyl) oxazoline, polyethyleneoxide (PEO), polyethylglycol (PEG), polyacrylacid (PAA), polyacrylonitrile (PAN), polyvinylacrylate (PVA), polyvinylpyrrolidone (PVP), or a combination thereof.
  • In a particular embodiment, the ceramics can include calcium phosphate, hydroxyapatite, calcium sulfate, bioactive glass, or a combination thereof. In an alternative embodiment, the injectable biocompatible materials can include one or more fluids such as sterile water, saline, or sterile air.
  • In a particular embodiment, the hardness of the material used to inflate the interior chamber 402 can be less than or equal to the hardness of the material used to inflate the exterior chamber 404, i.e., after the materials used to inflate the interior chamber 402 and the exterior chamber 404 are cured. Alternatively, the viscosity of the material used to inflate the interior chamber 402 can be less than or equal to the viscosity of the material used to inflate the exterior chamber 404.

Further, the ends 602, 604 of the tether 600 can be brought together and one or more fasteners can be installed therethrough to connect the ends 602, 604. Accordingly, the tether 600 can be installed in order to prevent the distance between the spinous processes 500, 502 from substantially increasing beyond the distance provided by the multi-chamber expandable interspinous process brace 400 after it is expanded and to maintain engagement of the interspinous processes with the spinous process pockets 410, 412, the engagement structures 420, 422, or a combination thereof.

Accordingly, the spinous process engagement structures 1320, 1322, the spinous process pockets 1314, 1316, or a combination thereof can substantially prevent the multi-chamber expandable interspinous process brace 1300 from migrating with respect to the spinous processes 1400, 1402.
  • Also, in a particular embodiment, the multi-chamber expandable interspinous process brace 1300 can be movable between a deflated configuration, shown in FIG. 13, and one or more inflated configurations, shown in FIG. 14 and FIG. 15. In the deflated configuration, a distance 1410 between the superior spinous process pocket 1314 and the inferior spinous process pocket 1316 can be at a minimum. However, as one or more materials are injected into the chambers 1302, 1304, 1306 the distance 1410 between the superior spinous process pocket 1314 and the inferior spinous process pocket 1316 can increase.
  • Accordingly, the multi-chamber expandable interspinous process brace 1300 can be installed between a superior spinous process 1400 and an inferior spinous process 1402. Further, the multi-chamber expandable interspinous process brace 1300 can be expanded, e.g., by injecting one or more materials into the chambers 1302, 1304, 1306 in order to increase the distance between the superior spinous process 1400 and the inferior spinous process 1402.
  • Alternatively, a distractor can be used to increase the distance between the superior spinous process 1400 and the inferior spinous process 1402 and the multi-chamber expandable interspinous process brace 1300 can be expanded to support the superior spinous process 1400 and the inferior spinous process 1402. After the multi-chamber expandable interspinous process brace 1300 is expanded accordingly, the distractor can be removed and the multi-chamber expandable interspinous process brace 1300 can support the superior spinous process 1400 and the inferior spinous process 1402 to substantially prevent the distance between the superior spinous process 1402 and the inferior spinous process 1400 from returning to a pre-distraction value.
  • In a particular embodiment, the multi-chamber expandable interspinous process brace 1300 can be injected with one or more injectable biocompatible materials that remain elastic after curing. Further, the injectable biocompatible materials can include polymer materials that remain elastic after curing. Also, the injectable biocompatible materials can include ceramics.
  • For example, the polymer materials can include polyurethanes, polyolefins, silicones, silicone polyurethane copolymers, polymethylmethacrylate (PMMA), epoxies, cyanoacrylates, hydrogels, or a combination thereof. Further, the polyolefin materials can include polypropylenes, polyethylenes, halogenated polyolefins, or flouropolyolefins.
  • The hydrogels can include polyacrylamide (PAAM), poly-N-isopropylacrylamine (PNIPAM), polyvinyl methylether (PVM), polyvinyl alcohol (PVA), polyethyl hydroxyethyl cellulose, poly (2-ethyl) oxazoline, polyethyleneoxide (PEO), polyethylglycol (PEG), polyacrylacid (PAA), polyacrylonitrile (PAN), polyvinylacrylate (PVA), polyvinylpyrrolidone (PVP), or a combination thereof.
  • In a particular embodiment, the ceramics can include calcium phosphate, hydroxyapatite, calcium sulfate, bioactive glass, or a combination thereof. In an alternative embodiment, the injectable biocompatible materials can include one or more fluids such as sterile water, saline, or sterile air.
  • In a particular embodiment, the hardness of the material used to inflate the central chamber 1302 can be less than or equal to the hardness of the material used to inflate the first lateral chamber 1304 and the second lateral chamber 1306, i.e., after the materials used to inflate the central chamber 1302, the first lateral chamber 1304, and the second lateral chamber 1306 are cured. Alternatively, the viscosity of the material used to inflate the central chamber 1302 can be less than or equal to the viscosity of the material used to inflate the first lateral chamber 1304 and the second lateral chamber 1306. In a particular embodiment, certain or all of the injected materials can be cured or cross-linked in situ to form a solid interspinous process brace with non-uniform bulk properties.
  • FIG. 15 indicates that a tether 1500 can be installed around the multi-chamber expandable interspinous process brace 1300, after the multi-chamber expandable interspinous process brace 1300 is expanded as described herein. As shown, the tether 1500 can include a proximal end 1502 and a distal end 1504. In a particular embodiment, the tether 1500 can circumscribe the multi-chamber expandable interspinous process brace 1300 and the spinous processes 1400, 1402. Further, the ends 1502, 1504 of the tether 1500 can be brought together and one or more fasteners can be installed therethrough to connect the ends 1502, 1504. Accordingly, the tether 1500 can be installed in order to prevent the distance between the spinous processes 1400, 1402 from substantially increasing beyond the distance provided by the multi-chamber expandable interspinous process brace 1300 after it is expanded and to maintain engagement of the interspinous processes with the spinous process pockets 1314, 1316, engagement structures 1320, 1322, or a combination thereof.
  • In a particular embodiment, the tether 1500 can comprise a biocompatible elastomeric material that flexes during installation and provides a resistance fit against the inferior process. Further, the tether 1500 can comprise a substantially non-resorbable suture or the like.

  • Description of a Method of Treating a Spine
  • Referring to FIG. 22, a method of treating a spine is shown and commences at block 2200. At block 2200, 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 2202, the spine can be exposed in order to expose adjacent spinous processes. Further, at block 2204, a surgical retractor system can be installed to keep a surgical field open.
  • Moving to block 2206, 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 2208, a distance between the adjacent spinous processes can be measured. Thereafter, at block 2210 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 impingement on a nerve root.
  • If the distraction is not correct, the method can return to block 2206 and the superior vertebra and inferior vertebra can be further distracted. Conversely, if the distraction is correct, the method can move to block 2212 and a multi-chamber expandable interspinous process brace can be installed between a superior spinous process and an inferior spinous process. Thereafter, at block 2214, each chamber within the multi-chamber expandable interspinous process brace can be inflated.
  • Moving to block 2216, each chamber within the multi-chamber expandable interspinous process brace can be sealed. In a particular embodiment, each chamber within the multi-chamber expandable interspinous process brace can be sealed by curing the material within the each chamber of the multi-chamber expandable interspinous process brace. Alternatively, a plug, a dowel, or another similar device can be used to seal each chamber within the multi-chamber expandable interspinous process brace. Further, a one-way valve can be incorporated into each chamber of the multi-chamber expandable interspinous process brace and can allow material to be injected into each chamber of the multi-chamber expandable interspinous process brace, but prevent the same material from being expelled from each chamber of the multi-chamber expandable interspinous process brace.
  • At block 2218, each injection tube can be removed from the multi-chamber expandable interspinous process brace. Moreover, at block 2220, the material within one or more chambers of the multi-chamber expandable interspinous process brace can be cured. In a particular embodiment, the material within the multi-chamber expandable interspinous process brace can cure naturally, i.e., under ambient conditions, in situ. Alternatively, the material within one or more of the multi-chamber expandable interspinous process brace can be cured or crosslinked in situ using an energy source. For example, the energy source can be a light source that emits visible light, infrared (IR) light, or ultra-violet (UV) light. Further, the energy source can be a heating device, a radiation device, or other mechanical device. Alternatively or in addition, the material in one or more of the chambers can be crosslinked by introducing a chemical crosslinking agent into the chamber before removing the injection tube from the chamber.
  • Proceeding to block 2222, a tether can be installed around the multi-chamber expandable interspinous process brace. The tether can be installed in order to prevent a distance between the superior spinous process and the inferior spinous process from increasing substantially beyond the distance provided by the multi-chamber expandable interspinous process brace.
