    摘要: A method for replacing a spinal disc between first and second vertebrae of a spinal column includes determining a reference point on the spinal column. A marker is connected to a vertebra of the spinal column at the reference point. The marker is engaged with a guide assembly for guiding insertion of a surgical instrument between the first and second vertebrae to prepare the space between the first and second vertebrae for receiving an apparatus between the first and second vertebrae. The apparatus is inserted between the first and second vertebrae. The apparatus has a first end, a second opposite end, and first and second lateral sides extending between the first and second ends. An outer surface is engageable with the first vertebra of the spinal column. A rail extending from the outer surface is engageable with the first vertebra to connect the apparatus to the first vertebra. The rail extends a first distance from the outer surface adjacent the first end. The rail extends a second distance from the outer surface adjacent the second end. The second distance is greater than the first distance. A first projection extending from the outer surface is engageable with the first vertebra to connect the apparatus to the first vertebra. The first projection extends from the outer surface a first distance. A second projection extending from the outer surface is engageable with the first vertebra to connect the apparatus to the first vertebra. The second projection is located closer to the second end than the first projection. The second projection extends from the outer surface a second distance greater than the first distance. In another aspect of the apparatus, first and second rails extend from the outer surface. The first rail extends generally transverse to the first and second ends. The second rail extends generally transverse to the first rail.

    摘要: A robotic system for performing minimally invasive spinal stabilization, using two screws inserted in oblique trajectories from an inferior vertebra pedicle into the adjacent superior vertebra body. The procedure is less traumatic than such procedures performed using open back surgery, by virtue of the robot used to guide the surgeon along a safe trajectory, avoiding damage to nerves surrounding the vertebrae. The robot arm is advantageous since no access is provided in a minimally invasive procedure for direct viewing of the operation site, and the accuracy required for oblique entry can readily be achieved only using robotic control. This robotic system also obviates the need for a large number of fluoroscope images to check drill insertion position relative to the surrounding nerves. Disc cleaning tools with flexible wire heads are also described. The drilling trajectory is determined by comparing fluoroscope images to preoperative images showing the planned path.

    摘要: An example apparatus places translaminar screws across a facet joint between adjacent first and second vertebrae in a minimally invasive surgical procedure. The apparatus includes a first K-wire, a second K-wire, a first fixation block, a second fixation block, a support block, a first rod member, a second rod member, and a cannula. The first K-wire is inserted into the spinous process of the first vertebrae. The second K-wire is inserted into a transverse process of the second vertebrae. The first fixation block has perpendicularly extending first and second passages. The first K-wire extends into the first passage in the first fixation block. The second fixation block has perpendicularly extending first and second passages. The second K-wire extends into the first passage in the second fixation block. The support block has perpendicularly extending first and second passages. The first K-wire extends into the first passage in the support block. The first rod member extends through the second passage in the first fixation block and the second passage in the second fixation block. The second rod member further secures the first and second fixation blocks to the first and second vertebrae. The second rod member extends through the second passage in the support block. The cannula enables implantation of the translaminar screws across a facet joint between the first and second vertebrae.

    摘要: An apparatus (10) for cutting bone includes a shaft member (12) having a central axis (14) and extending between a proximal end portion (16) and a distal end portion (18). The proximal end portion (16) has a first surface (32) adapted to receive repetitive impacts. The distal end portion (18) includes a cutting blade (40) extending in a first plane between a shield section (46) and a guide portion (60). The shield section (46) and the guide section (60) project axially beyond the cutting blade (40) to recess the cutting blade (40) in the distal end portion (18). The shield section (46) includes an inwardly facing shield surface (48) which extends in a second plane that is transverse to the first plane of the cutting blade (40). The apparatus (10) is a form of an osteotome that is particularly useful for certain spine-related surgical procedures.
