2 a itELl OF THE INVENTION

The present #_n4 t i .ion r~-,lates to spina i implants and associated me thuds.
BACKGROUND
A:'l e ve tetra of the human spine are arranged in a colurnm with one vertebra on top of the next An in.ervertebrai disc lies between adjacent vertebrae, to trans .it force between the adjacent vertebrae and pro-vide a cusp ion between them. The discs all:
s.~ the spine to flex and twist, With age, spinal discs begin to break down, or degenerate zresulti the loss of fluid in the discs and consequentl res ltin in them becoming less fexible.
Likewise, the disks become thinner allowing the vertebrae, to move closer together.
Degeneration may also result in tears or cracks in the outer laver, or annulus, of the disc. The disc may begin to bulge outwardly. In more severe cases, the inner material of the disc, or nucle.is. may actually extrude OW of the d sc= in addition to degenerative changes in the di sc, the spine may undergo changes due to trauma - room automobile accidents, falls, heavy fling, and othe r activities, .Ej kil. therniod e, in a process known as sp. inal stenosis, the spinal canal narrows dae to excessive bone growth, thickening of t-ss_e in th.e canal (such as liga nnent), or both. In all of these conditions, the spaces ,t -eugh which the spinal cord and the spinal nerve roots pass may become narrowed leading to pressure on the nerve tissue which can cause pain, numbness, weakness, or even paralysis in various parts of the body Finally, the facet joints between adjacent vertebrae may degenerate and cause localized and.: or radiating pain. All of the above conditions are E ollectively' reaerre to here n as spine disease.

Conventionally, s: rgeons treat spine disease by attempting to rQszore the normal spacing between adjacent ve; tebrae. This ::ay be stiff cient to relieve pressure from affected new tissue. -However, it is often necessary tt also surgically remove disc niatei'iaal, bone, or other tissues that impinge on the i rve tissue arid./or to deb ride the facet joints. Most often, the restoration of vertebral spacing is accomplished. by inserting a rigid spacer made of bome., S
irietal. or plastic into die disc space. bet ~ en the adjacent vertebrae and allowing the v r .enrae to grow tugetl e;', or fuse, into a single piece of bone. The vertebrae are typically stabilized Est, n this fusion process with the use of bone plates and{or pedicle screws fastened to the adjacent. \ertehrae.

[T,41 Although techniques for placing inter verteb al spacers. plates, and pe icle scre w fixation s}'.. r: .. have become loss invasive in recent y'e.ars, they still require the placement of hardware deep within the surgical site adjacent to the spine. Recovery from Such surgery can t _iire several days of hospitalization and lonk, slow rehabilitation to normal activity y levels, [13] More r'ece`:tl ', nivest`.gators have promoted the. use of motion preserv, , on implants and techniques in which adjac_cut. vertebrae are permitted to move relative to ore another.
One sucl: implant that has met with only limited success is the art ficial disc implant. These ' AC i ll include either a flexible material or `ca two-piece articulating joint inserted in the disc space. Another such implant is the spinous process spacer. which is inserted between dIe posteriorly extending s ainou r processes of adjacent vertebrae to act as an extension stop a d to maintain.. a minimum spacing between the sp nous roc: ssv _ when the spine is in extension. "P he spinous process spacer allows the adjacent pinous processes o move ii art as the spine is fete..

Throughout this specification, the spinal implant will be referred to in the context of a sphious process immplant. However, it is to be understood that the cps.n nn ant rnay be configured for insertion into the cervical, horn cIL, aà d or lnmbau spine between adjacent Sprott s processes, trCan \Aersse processes, andsro} other vertebral structures. The spacer may be provided in a variety of'sizes to accommodate ees o pa correction. h spacer.
anatomical variation amongst paÃ3L_: and aryi#a deg may include openings to facilitate tissue ingrowth to archon the spacer to the Vertebral bodies such as tissue Ãi -growth from the spine. For example, the spacer may be configured for tissue in-growth from superior and inferior spinous p:iocesses to cause.
fusion of the d . n lid?xr`ou processes. The openings may be relatively large and/or o"21municate to a hollow interior of the spacer. A. hollow interior may h configured to receive bone growth promoting subsÃances such ar by packing the substances into the hollow interior. `F he openings as be iclatii' ,'`,v small and oi: comprise pores or F lte:"co nec ing pores over <3: feast a portion of the spacer surface. The openings may be filled with bone growth promoting sÃ.ibst8tccs, [178, The spacer may have a: y suitable cross-sectional shape. For example, it may be cylindrical, w ed ge shaped. .'D-draped. C -shaped, H-shaped, include separated cantilevered hear ic. an.d/or any other sums le I .pe. ']'he shape may include chamfers, fillets, fats, reef cuts, and/or other features to accommodate anatomical features such as for examuic. the laminae and/or facets, 1.791 The spacer r aq be Ãncoirtpressible, moderately compressible, highly compressible, convertible from compressible to ineo pressible_ arid) or anyother configuration. For example., the spacer iliay be conip esL i bi into a comp of c 3nf tguration for Inserdorl between adjacent bones and then, expandable to space the bones apart. The spacer m .
be allowed to flex to provide a resilient cushion between the bonesThe spacer m -y be locked in the expanded coriditjoii to prevent it from returning to the compact L on iir Lion.

The retention member may extend transversely from f he spacer re'a`ti'L"e to a spacer ! ,E3 lon zt .dinal axis to maintain the spacer between adjacent spinous processes.
A single retention member may extend in one or more directions or multiple extensions arlay be provided that extend in multiple dÃaections. Ohio ori3 ore retention members may be fixed relative to the spacer longitudinally and/or radially~. One or more retention members may be adjustable relative to the spacer and/or other Teter tion m ambers longitudinally and or radially to allow the retention mer,. bera to be positioned relative to the spit ious processes. The retentinn aiernbers may be dt plo a :e tliroo i and or fior within the spacer to allow the spacer to be placed and th ctention met bers deployed in a mirii ally invasive MWUICI,.

The retention rrcmhers may incna e ore or more screws, pins, nails b s-,Ins s't iples. hook:, plates, wings, bars, ex-tensi ns, lrlament;s, Wires, loops, ban as, straps, cables, cords, Nsutures, an d.eor otl cr stiitahle r tea itioi, ,-,i'. aocr.

The retention members and/or fasteners, may he adj ,:stable, eplÃaceable, and/o temovahk and i ay be ennployed in one direction and1 or on one side of the implant or in m ultiple directions and/or on multiple sides of the implant to allow tailoring of the kind and quality of fixation of adjacent bones. For example, the implant may be placed such that it acts only as a spacer between adjacent bones, as an elastic restraint between adjacent hones, or as a rigid fixation between adj 3.centi bones. The spacer, retention members, aad'aor fasteners may advantageously be trade of different i aterials.

For t .ample. sires, straps, sands, cables, cords, and/or other elongated members may encircle the p`dicies, laminae, sp n'was processes, transverse pro ss , and/or other spinal ses. t u ctur The cerciage may be relatively inextensible to provide a hard chcL k to s ine flexion or the cerclagc ma e .relatively extensile to pro=wide inc easÃng resistance to flexion. The cerclage may be Ãe.1;tiv ely flexible and drapeable such ; s a woven fabric or it i:aaa.y be relatively rigid s ich as a metal fiend. The cerciage may have shape memory properties that cause it to resume a prior set shape after implantation. The cerelage may be independent of the s i sous process implant or may, engage it. For exa iple, the cerciage may pass through a hollow interior of the spinous process implant and/or engage tie extension.
[T.83] The implant may be supplemented a th bone growth promoting substances to thcilitate fusion of adjacent vertebrae between spinous processes, laminae, transverse processes, facets, and/or other spinal structures. The bone growth promoting substances may be spaced from the its pliant. placed adjacent the implant, sandwiched beLween the Implant dedying bone, placed inside the implant, coated onto the implant, and/or othe wi a ail up placed relative to the implant. If it is coated onto the implant it may cover the entire implant or only selected portions of the implant such as the spacer, retention >

The surgical site is distracted (or measured as distraction may be caused by the spacer itself) rising conventional distra ction tools, step 320411, Office exposed, the u tern inotis pros space is prepared. to receive the spinal iinpltrnt, step 3206, This typically iii ,ii.tdes preparing th e spinous processes to accept the spinal lrnplaiit, which may i ,c ode removing som.m portion of the spinous process, and removing muscle, tendons, and ligaments that may interfere with implanting the spinal implant and/or may provide force tending to unseat the spinal implant.
)he first part of the spinal is inserted, over or with the guidewire,, to the surgicaal site through à .e incision or the like, step 3208. Once at the site, the first part of the spinal "Unplant is positioned or aligned such that t hl- lateral walls are loosely abuttin a first side of the superior and inferior spinous processes and the second end extends into the inter'spirno is space, step 3210, Generally, this means that ;lie fist part is implanted through the interspinous process space. The 4 :: lei ire, which is attached to the first part of the spinal imp' ant as explained above extends froni the second end of the first part and isaÃtac red to 3.7 the second pan of , , , iaa1 mplant, Thus. the surgeon inserts the second pail long: the guidewire, step 3212. Noe, the first part and second part may be positioned using tools or the surgeon may place the parts using hands and Using the guidew-ire, the protrusions (ii tl iy) of the second part are inserted into the channels of the first part (if atiy) to align the first part and second part of the spinal implant, step 324.
Compressive force is applied to mate the first. part and the second part, step 3216. The compressive force may be applied by crimping t _ Tire. threading a cable lock, a separate clad , or the like.
Once sufficiently compressed, the first part and second part are locked together, step 3218.
Optionally, excess gu de re may be, cut z nd removed or looped around the adjacent superior interior spinous process to provide iecured seating, stop 3220, Once mateed ill the a, and interspin ous space, the distraction of the spinal segment may be released, step 3222, and the patient's surgical site may be closed, step 3224.
