Definitions
- This invention relates to an apparatus for spinal column fixation. More particularly, but not by way of limitation, this invention relates to a mechanical device used to obtain a rigid posterior spinal column fixation in order to obtain a rigid posterior spinal column bony fusion for disabling back and leg pain.
- the apparatus includes a posterior fixation device which is attached to the involved vertebral bodies.
- the attachment is made by pedicle screws penetrating into the vertebral body with rigid attachment to ball-and-socket clamps and rods.
- the invention also may include a pair of intervertebral metallic or radiolucent wedges inserted into the disc space of the involved vertebrae to increase the stability of the spinal column anteriorly and to avoid breakage of the pedicle screw. Additionally, die application also discloses a method of placing the fixation and wedge device in a posterior lateral approach.
- Posterior spinal fusions have been performed on millions of people since at least the early 1900' s.
- the principle of bony fusion has been and still is stabilization or prevention of motion between two adjacent vertebral bodies.
- Another design utilizes screws inserted posteriorly through the pedicle into the vertebral body connecting to plates, rods and clamps to stabilize the two adjacent segments.
- the prior art pedicle screw devices have different functions.
- One function includes the correction of the degenerative curve of the lumbar spine between L3 and SI or traumatic deformities.
- These devices have the internal purpose of this device is correction of a deformity through two vertebra such as seen in U.S. Patent 4,987,892 to Martin H. Krag, and in U.S.
- Another function includes rigidly fixing the spinal column using a combination of intra- vertebral screws, plates, rods and clamps.
- U.S. Patents 4,615,681, 4,648388
- Another function includes flexible or semi-rigid fixation shown in U.S. Patents 4,913,134 to Luque; and, 4,743,260 to Buttem.
- the present invention utilizes the rigid posterior fixation device which is attached to the involved vertebral bodies through pedicle screws connected with a series of operably associated ball-and-socket clamps and rods.
- One such device using a ball connector is seen in U.S. Patent 4,946,458 to Harms.
- the prior art devices include several disadvantages. For instance, many devices were susceptible to breakage, and once breakage occurs, the devices are very difficult to retrieve. Also, the mechanism of clamps and rods is very complicated and difficult for the surgeon to install.
- the pedicle screw developed excessive motion and toggle. This in turn would cause the plate to become loose thereby allowing the plate to slide back and forth causing irritation, lack of fixation, and thus failure of fusion.
- the rigid devices without inter-body fusion or rigid spacer will result in breakage in the screw because of mechanical factors.
- the greatest portion of the weight of the individual is taken through the vertebral body and disc.
- the center of motion of the vertebral segments is located in the posterior aspect of the disc. In the lower lumbar spine the greatest amount of motion is flexion and extension of the trunk, therefore, the intervertebral segment motion is mainly to the anterior frontal or posterior backward movement.
- Rigid posterior fixation is at a mechanical disadvantage because d e forces of weight and motion are anterior to the rigid posterior fixation device. With repetitive motion the device either breaks or becomes loosened. Widi loosening or breakage, the motion will increase leading to more pain and failure.
- Sciatica is pain which shoots down the posterior lateral aspect of the leg. Sciatica is caused by impingement or encroachment on the neural elements in the lumbar spine. Recent studies indicate d at intervertebral body fusion is the most effective relief of sciatica. This is because the intervertebral disc is die mechanical center of motion between the intervertebral bodies, and die majority of the body weight of die individual is taken through the vertebral bodies.
- Prior art devices are designed and placed in the intervertebral disc comprise several concepts.
- One is to replace me disc which has been removed with an artificial disc material which can function and behave biomechanically similar to the normal intervertebral disc when inserted in the space.
- a second includes maintaining the disc height widi no attempt at inter-body fusion.
- a spacer is placed in after removal of the intervertebral disc.
- a diird involves maintaining height and obtaining a fusion with a fenestrated spacer that will contain a bone graft.
- the fenestrated spacer is placed in directly posteriorly under die neural elements.
- This invention solves these problem by combining the wedge insert anteriorly and the rigid posterior fixation device allowing the patient to obtain a solid, rigid fixation.
- the purpose of the wedge is to obtain anterior stabilization, restoration of intervertebral disc height, normal physiological lumbar lordosis, and intervertebral body bony fusion in the human spinal column.
- the posterior device stabilizes the mechanical dynamics associated witii posterior forces, and the wedge compensates die forces associated witii the anterior forces.
- the invention includes both apparatus and mediod claims to a spinal column fixation device that includes multiple clamping means for clamping onto an implanted screw in the sacrum and involved vertebrae of a patient.
- the clamping means will also contain a stabilizing rod and a portion to receive a receptacle stabilizing rod from a complementary clamping means.

- the implanted screws contain a first end and a second end, and wherein said first end contains external thread means for threading die implanted screws into die spinal column of the person, and more particularly into die pedicle of die involved vertebra, and sacrum.
- the second end contains a multi-sided, generally a hexagon, shaped nut member. Further, die hexagon shaped nut member has attached thereto a spherical handle end.
- the first, second, diird and fourth sacrum, as well as the first, second, and fifth vertebrae clamping means comprises a cap portion having an aperture therein, and wherein the cap portion has a first and second cavity formed tiierein, the first cavity being formed for receiving the spherical handle ends of die pedicle screws and die second cavity being formed for receiving die stabilizing rods. Also included is a base portion having an aperture therein, and wherein said base portion has a first and second cavity formed tiierein, the first cavity being formed for receiving die spherical handle ends of die pedicle screws and die second cavity being formed for receiving said stabilizing rod.
- a bolting member fitted dirough the aperture of the base and die cap is included and cooperating with the base and d e cap so that the spherical handle end and stabilizing rods are adapted to be received within the mating cavities.
- the stabilizing rod may extend from die third and fourth sacrum clamping means and has a spherical handle end
- die third vertebrae and fourth vertebrae clamping means will comprise a cap portion having an aperture tiierein, and wherein die cap portion has a first and second cavity formed therein, the first cavity being to receive said spherical handle end of die pedicle screws and die second cavity being formed for receiving the spherical end of the stabilizing rod, a base portion having an aperture therein, and wherein the base portion has a first and second cavity formed tiierein, with die first cavity receiving the spherical handle end of die pedicle screws and die second cavity being formed for receiving die spherical end of die stabilizing rod.

- the wedge may contain a threaded aperture for placement of bolting means for placement of an inserter to secure the wedge member for insertion into the discal space in a sagittal plane.
- the application also discloses a method of stabilizing motion of involved spinal diseased vertebrae with a spinal fixation device, the spinal fixation device containing a plurality of implanted screws, the implanted screws containing a first and second end, die first end containing thread means and die second end containing a spherical handle end, die spinal fixation device further containing a plurality of spherical clamp means for securing onto the spherical handle ends.
- the device also contains a plurality of interconnecting rods for interconnecting the ball clamp means.
- a wedge member is provided for insertion into inter-discal space.
- the metiiod comprises the steps of performing two posterior lateral incisions or alternatively, one posterior incision on the back of the patient to the area of the involved spinal diseased segments.
- the metiiod will expose die transverse process (Fig. 19, 224) of the involved spinal diseased segments; then, dissecting between and lateral to die transverse process of the involved spinal diseased vertebrae is performed so tiiat the nerve roots (Fig. 19, 216) and die annulus fibrosis (Fig. 18, 210) are exposed.
- a cruciate incision is placed in the annulus fibrosis (Fig.
- the pedicle screw is tiien rotated into the bored openings of the involved spinal diseased vertebrae witii the wrench; and, d e surgeon applies a spreader to the pedicle screws so tiiat the disc is opened for placement of die wedge member.
- the metiiod may also include die steps of selecting the proper length, height, angle of the wedge member, and then placing a bone in small pieces into the inter-discal space of die involved spinal diseased segments, and in the fenestration of the wedge for intervertebral fusion prior to insertion of the wedge 180.
- a test wedge may be first employed on a trial basis in order to insure selection of the correct size, length and angle of the wedge.
- die wedge is inserted (Figs. 16 and 17A-E) into the inter discal space of die involved spinal diseased vertebrae bilaterally, and die spreader is released which had been keeping the intra-pedicle screws separated tiiereby allowing the elasticity of the annulus fibrosis and adjacent tissue to lock the wedge in inter-discal space.
- the position of the intra-pedicle screws is examined with an image intensifier, and die ball clamp means is placed about the spherical handles of die implanted screws.
- the fastener member (nut) is tightened so that the ball clamp means will not slip off the spherical handle of die implanted screw. The surgeon will then determine die particular structural arrangement of the interconnecting stabilizing rods.
- the cutting of the interconnecting stabilizing rods is performed, widi or witiiout spherical balls on the end, to die proper length, and the interconnecting rods are placed into the ball clamp means so that the ball clamp means are linked; and tightening of the ball clamp means is executed so that the ball clamp means encases the spherical handle end and die interconnecting rods. Because of the curved contour of the spinal column, some bending and shaping of the rods may be necessary.
- the application also includes a step wherein die process of placing the drill point on the involved spinal diseased vertebral bodies and drilling a bore hole in the involved spinal diseased vertebral bodies includes: placing the drill point on a first and second site of die pedicle of die sacrum; then, placing the drill point on a first and second site of the ala of die sacrum and drilling a bore hole to the first and second site on the ala of the sacrum; then, placing the drill point on a first and second site of the pedicle of die L5 involved spinal diseased vertebral body and drilling a bore hole to the first and second site of die L5 involved spinal diseased vertebral body; and, placing the drill point on a first and second site of die pedicle of die second involved spinal diseased vertebral body and drilling a bore hole to die first and second site of die L4 involved spinal diseased vertebral body.
- a feature of the present invention includes die ability of using one or two screws on each side of die sacrum. Another feature includes use of triangular cross fixation rods to increase posterior stability. Yet another feature is that when combined with the wedge of die present invention, the device increases stability of the spinal column anteriorly and to avoid breakage of the implanted screws, die wedge creates support in the inter-discal space as well as creating the normal lordosis and increasing stability. Another feature includes fewer moving parts which allows for the clamps to be mechanically cross connected. Another feature consist of the ball in the socket concept which allows for connecting two clamps at variable angles in both a horizontal and vertical plane, depending on die circumstances of each individual patient. The interconnecting stabilizing rods widi a spherical handle end can rotate while in place in the clamping means up and down, as well as laterally relative to the implanted screw.
- Still another feature includes die capability of measuring the length of the stabilizing rods during the procedure and cutting the rods to die appropriate length in order to conform to the particular circumstances of the patient. Still yet another feature consist of having less fiddle factor. Another feature consist of having the stem as the weakest point of the implanted screw member which allows for easy removal of me screw if breakage occurs. Put another way, the screw can easily be extracted because the nut and die penettated portion of the screw is still intact.
- An advantage of die present invention includes tiiat the device is easy to insert. Another advantage is that the device allows for adjustable tightness of the various securing means. Yet another advantage includes avoiding breakage of screws. Another advantage is tiiat multiple clamps connecting to individually associated intra- pedicle screws allows for variations in the number of connecting rods and the variations in the pattern of interconnection. Still another advantage includes that the lamina and die spinous process are not disturbed which leaves a large area for bone grafting. Yet another advantage of the procedure allows for ease of facet joint fusion. Still anodier advantage consist of the anterior and die posterior rigid fixation and the large bone grafting area achieved by this invention which leads to solid bony fusion.
