Respective upper and lower end parts axially flank the center part and each have an inner end threaded onto a respective one of the screwthreads and an outer end adapted to bear on a respective one of the vertebrae. One of the end parts is formed with an eye having a hole open transversely of the axis. A screw engages through the hole and anchors the one end part to the respective vertebra. The other end part is also formed with an eye having a hole open transversely of the axis and another screw engages through this hole and anchors the other end part to the respective vertebra.

The present invention relates to a vertebral implant. More particularly this invention concerns such an implant used to replace one or vertebrae and/or intervertebral disk.
When a vertebra is broken or crushed it is frequently necessary to ablate the body of the crushed or broken vertebra or vertebra as well as any damaged intervertebral disk. In order, however, to prevent the spinal column from collapsing with damage to the fragile spinal cord running in the vertebral foramen forward of the vertebral body, it is necessary to implant a spacer. This implant is braced vertically between the bodies of the adjacent vertebra and holds them apart at the desired spacing.
In commonly owned U.S. Pat. No. 5,571,192 a spinal implant is described having a tubular center part extending along an axis and a pair of end parts. The center part is formed with upper and lower screwthreads of opposite hand and with a plurality of radially throughgoing apertures. The upper and lower tubular end parts are each formed with a plurality of radially throughgoing apertures, each have a circular-section inner end threaded onto a respective one of the screwthreads, and each have an outer end adapted to bear on a respective one of the adjacent vertebrae.
Such an implant is highly effective. Nonetheless its installation is somewhat tricky until it has been expanded into place so that the two end parts bite into the respective vertebrae. In addition the entire implant area is not stable until there has been substantial bone growth around and through the implant, so that the patient must be very careful to avoid any displacement of the implant before it sets fully.
It is therefore an object of the present invention to provide an improved vertebral implant.
Another object is the provision of such an improved vertebral implant which overcomes the above-given disadvantages, that is which can be solidly anchored in place.
A spinal implant for engagement in a space between a pair of adjacent vertebrae has according to the invention a center part extending along an axis and formed with upper and lower screwthreads of opposite hand. Respective upper and lower end parts axially flank the center part and each have an inner end threaded onto a respective one of the screwthreads and an outer end adapted to bear on a respective one of the adjacent vertebrae. One of the end parts is formed with an eye having a hole open transversely of the axis. A screw engages through the hole and anchors the one end part to the respective vertebra. Normally in accordance with the invention the other of the end parts is also formed with an eye having a hole open transversely of the axis and another screw engages through the hole of the other end part and anchors the other end part to the respective vertebra.
Thus it is possible to anchor the implant solidly to the spine. The cortical screws engage well into the respective vertebrae so that the implant is not only held in place by engagement of upper and lower normally toothed faces of the end parts in the overlying and underlying vertebrae, but also by these screws. The result is a solid uniting of the implant to the two flanking vertebrae. Thus even if considerable torque is exerted on the center part to distract these vertebrae, the end parts will stay put.
The ability to anchor both end parts to the respective vertebrae is particularly advantageous when accommodating certain installations. For example when the implant is to be installed at the lower end of the vertebrae above the sacral vertebrae, it is advantageous to be able to work from above, with screws angled down through the lower element into the sacrum. Thus the operating field can be small. Furthermore the implant lies wholly between the vertebrae it is mounted between, within the vertical projection of the spine so that it can be left in place and the operating wound can be closed and left closed.
The eye of the other end part according to the invention is formed as a tab extending generally parallel to the axis so that its hole and the screw through it is generally perpendicular to the axis.
In another arrangement the eye is open at an acute angle away from the other part and is thickened. Normally the eye is open at an angle of between 25° and 65° to the axis, preferably 45°.
The eye according to the invention is unitarily formed with the one end part. In addition the inner ends are formed as axially extending stems and the center part is a sleeve threaded over the stems. In addition the parts are formed with radially open throughgoing holes so that bone can grow into and through the parts. These parts can be made of titanium, a biocompatible plastic, ceramic, or bone.
FIG. 1 is a side view partly in vertical section through the implant according to the invention;
FIG. 2 is a front view of the bottom part of the implant;
FIG. 3 is a horizontal section through the implant when installed;
FIG. 4 is a side view of the installed implant;
FIG. 5 is a view like FIG. 4 but with the implant installed in the caudal area of the spine; and
FIG. 6 is a view like FIG. 4 of another implant in accordance with the invention.
As seen in FIGS. 1 and 2 an implant 1 according to the invention for installation between a pair of vertebrae 2 has a lower end part 3, and upper end part 4, and a center sleeve or part 5, all made of a biologically inert or absorbable material such as steel, titanium, bone, bioceramic, or polyetherether-ketone (PEEK). The upper part 2 has a downwardly extending externally threaded tubular stem 18 and the lower part 3 has an upwardly extending externally threaded tubular stem 15. The screwthreads of the stems 15 and 18 are of opposite hand and mate with complementary screwthreads in the sleeve part 5 so that rotation in one direction relative to a center axis A will spread the parts 3 and 4 vertically and distract the vertebrae 2 and opposite rotation will move them together. The upper and lower surfaces of the parts 3 and 4 can be parallel to each other but are normally inclined at a slight acute angle to each other, making the implant 1 wedge shaped to correspond to the normal lordosis of the spine.
The parts 3 and 4 are formed with radially throughgoing holes 13 and with an axially extending slot 13′ so that an interior 14 can be packed with bone chips and so that bone growth through the implant 1 is possible. In addition the parts 3 and 4 have lower and upper surfaces formed with teeth 17 that bite into the respective end surfaces 10 of the vertebrae 2 to prevent the implant 1 from slipping.
According to the invention the lower part 3 is unitarily formed with a pair of eyes 6 having collars 7 defining holes or passages 8 with cylindrical inner surfaces 12 extending at an acute angle of between 25° and 65° to the lower vertebral surface 10, here 45°. Cortical screws 9 extend through these eyes 6 and into the lower vertebra 2 to solidly anchor the lower part 3 to the lower vertebra 2. FIG. 6 shows how a similar pair of eyes 6 can be formed on the upper end part 4 in an arrangement allowing the implant 1 to be installed through a very small surgical opening.
In FIGS. 1, 4, and 5 the upper part 4 has a pair of bent-up tabs or flanges 11 formed with openings 16 extending parallel to the upper vertebral surface 10. Cortical screws 9 extend perpendicular to the axis A through the openings 16 to anchor the upper part 4 to the upper vertebra 2.
Thus with this system, after the disk or vertebra has been ablated, the implant 1 is set in position and the sleeve part 5 is rotated to press the teeth 17 lightly into the lower and upper surfaces of the vertebrae above and below the implant. Then pilot holes are drilled in line with the holes 8 and 16 and cortical screws 9 are threaded through them into the vertebrae 2, anchoring the implant 1 solidly in place. The sleeve 5 can then be rotated further to achieve the desired level of distraction, and the operating field is closed.
