An implant device is provided for implantation within an intervertebral space between adjacent vertebrae comprising an implant body, a rotatable portion and a piercing portion configured to pierce the adjacent vertebra.
摘要:
A prosthetic spinal implant having a deployable securing mechanism that is deployable into a portion of the vertebral space for affixing the implant between the vertebrae, the securing mechanism having tactile feedback means comprising a surface for transmitting tactile feedback during deployment of the securing mechanism. A spinal implant having deployable securing means that interface with the implant to prevent the deployable securing means from retracting after deployment. An implant that utilizes its resilient properties to provide the user with tactile feedback with which the user may ascertain the position of the securing mechanism. A system and tools for sizing and implanting implants with the aforementioned characteristics.

A bone fixation apparatus and method are provided that allow a user to push bone pins into engagement with bones with more precision and accurate feel as to proper engagement and the clamping forces between the pins and bone over prior devices utilizing applicator guns and the like. Fine tuning of the clamping forces is also contemplated. Compact and highly ergonomic bone fixators are provided which allow the user to remain close to the pin application site during clamping of the pins onto the bone. Significant flexiblity is preferably incorporated by having two adjustably connected positioner bodies which can each mount a pin holder module releasably attached thereto. A fixation system with improved rigidity is also provided by way of independent clamping members for each of a pair of rod mounts on each pin positioner. The independent clamp members keeps their size to a minimum while allowing the angular separation of connecting rods secured in the rod mounts and spanning and interconnecting two fixators to be optimized, e.g. approximately eighty degree angular spacing, from a system stability standpoint.

An artificial disc device for replacing a damaged nucleus is disclosed. In one form, the device may be inserted in components such that the device may be assembled within and retained by the natural annulus therein. In another form, the device may be inserted into the natural annulus in a collapsed or compressed state or arrangement and then be expanded within and retained by the annulus therein.

An apparatus for advancing surgical devices such as spinal rods is disclosed. The spinal rod may be advanced, for instance, into a seated engagement with a surgical fixture, such as a fixture having a screw mounted in a bone portion, and the fixture may have an open end forming a yoke into which the spinal rod is seated. The apparatus may include portions which secure to the yoke in a pre-determined arrangement or orientation, and the portions may be locked into place by a series of linkages on the apparatus. The apparatus may include a movable member that is non-rotatably shifted longitudinally for advancing the spinal rod into the seated engagement, and the movable member may then be rotated without shifting longitudinally to rotate a securing member such as a cap into a position within the yoke to at least partially capture the cap therein.

A Pilates step barrel/chair exercise apparatus has side walls and a unique elastic resistance member anchor structure fastened to each of the side walls. Each anchor structure has an anchor socket assembly fastened to one of the side walls and a removable elastic member anchor bar assembly mounted in the anchor socket assembly. The anchor socket assembly has a central tubular portion passing through the one of the side walls and a flange portion fastening the tubular portion to the side wall. The anchor bar assembly has an L shaped anchor bar, a cylindrical yoke receiving and holding a long leg of the anchor bar, and a spring bar tube rotatably fastened to a short leg of the anchor bar. The cylindrical yoke has a portion adapted to fit within a central bore of the tubular portion of the anchor socket assembly, and has a plurality of spaced radial holes therearound for engaging with and retain the anchor bar assembly in the anchor socket assembly.
摘要:
A spinal column reconstruction device is disclosed including at least two bone surface engagement portions, each for fixation to distinct vertebral bone portions, a mobile portion of the device positioned between the two bone surface portions and providing for movement therebetween, and a motion limiter portion generally fixing the bone surface engagement portions in a predetermined positional orientation for reconstruction of the spine.
摘要:
Implant devices in the form of a vertebral body replacement for implantation within an intervertebral space between adjacent vertebrae is disclosed for immobilization and support of the adjacent vertebrae in a desired spatial relationship and for promotion of fusion by the adjacent vertebrae. Instruments for insertion and implantation of the implant devices and of fusion material such as bone graft material are disclosed. Methods are disclosed for implantation of the implant devices.
