摘要： A system and method for anterior fixation of the spine utilizes a cylindrical implant engaged in the intra-disc space at the cephalad and caudal ends of the construct. The implants are cylindrical fusion devices (10) filled with bone material to promote ingrowth and fusion of the disc space. An attachment member is connected to each of the fusion devices (10) and bone screws (30) having similar attachment members (33) are engaged in the vertebral bodies of the intermediate vertebrae. A spinal rod (50) is connected to each of the attachment members using an eyebolt assembly (53-55). In a further inventive method, a revision of the construct is achieved by removing the fusion devices. Each fusion device is engaged by an elongated guide member (62) over which a cylindrical trephine (70) is advanced. The trephine (70) has an inner diameter larger than the diameter of the fusion implant.

摘要： Spinal implants with features for anchorage in or onto bone or to connectors, have a body (31) with an upwardly opening channel (32) receiving a spinal rod therein. The channel has sidewalls with a curved slot (36, 37) in each of the sidewalls. A cap (46) is mounted on the implant body and has a central portion received in the channel and has tongues (48) at each side of the central portion, the tongues being received in the curved slots in the sidewalls. A set screw (57) threaded into the cap engages the spinal rod and clamps the rod between the body and the set screw and fixes the cap to the body. The curved slots enable installation of the cap in minimal space measured lengthwise of the rod. Each implant body has an integral bone screw (Fig. 2) or bone hook (18, Fig. 15), or lateral connector rod (87, Fig. 18) or parallel spinal rod receiving body (99, Fig. 20, 21) thereon.

摘要： A reciprocating cutting instrument (10) includes an outer tube (13) housing an inner reciprocating cutting blade (20), which is engaged to a motor through a transmission and drive mechanism (50). This transmission and drive mechanism (50) convert rotary drive movement of the motor to reciprocating movement of the cutting blade. A cam (80) which is formed by a generally cylindrically shaped cam barrel (89) with a cam channel (85) defined in the outer surface of the barrel, engages the spindle of the motor. A drive ball (86) rides within the channel and is supported within a boss (77) of a linear in-line driver (75), which reciprocates within a bearing (65) housed by a driver cartridge (52). Pressure between the drive ball (86) and the cam channel (85) is maintained by a set screw (87) threaded into the boss (77) in the in-line driver (75). As the motor rotates, the spindle, which is engaged to the cam, rotates the cam barrel, which causes the cam channel to pass underneath the drive ball (86), forcing the drive ball to follow the channel path.

摘要： A clamp (80) is provided for clamping a spinal rod (R) to a vertebral fixation element (73) which permits access directly from the top of the instrumentation site. The clamp (80) includes a body (81) defining a channel (82) configured to receive the spinal rod (R) and a pair of conical sleeves (120) for restrainably securing the spinal rod to the clamp by forcibly inserting the sleeves between the spinal rod and the channel. The clamp further includes a projection (89) extending from the body, terminating in a T-bar (90), and a washer (92) slidably disposed on the projection between the T-bar and channel. As the conical sleeves are forcibly inserted into the channel, the sleeves bear upon the washer and displace the washer in the direction of the T-bar, thereby clamping the vertebral fixation element between the T-bar and washer. The dual function of the conical sleeves thereby clamps the spinal rod to a vertebral fixation element.

摘要： An internal anterior fixation system (10) for treatment of vertebral burst fractures includes an elongated plate (11) which includes integral superior (12), inferior (20) and bridge portions (25). The superior (12) and inferior (20) portions are provided for fixation to corresponding vertebrae while the bridge portion (25) spans between the portions over the affected vertebra. The superior portion (12) includes a pair of generally parallel elongated slots (15) therethrough each having scallops (40, 42) for receiving a bone fixation screw (22). The inferior portion (20) includes a pair of openings (21) through which fixation screws or bolts extend. The slots (15) in the superior portion (12) allow for compression or distraction of the intermediate vertebral region. The openings (21) in the inferior portion (20) are oriented at an oblique angle (A) relative to the axis of the plate to provide a quadrilateral fixation construct. The bridge portion (25) has a width (W) significantly less than the width of the superior and inferior fixation portions.

摘要： A spinal fixation system (20) includes a relatively rigid fixation plate (21) which is engaged to a plurality of vertebrae by bone fasteners. The plate includes a longitudinal slot (22) with an arrangement of scallops (29) formed at the upper and lower edges of the slot. The scallop arrangement (29) includes a first set of scallops (30) formed at one spherical radius R2 and a second set of scallops (31) at a smaller radius R1 nested within the first scallops. Thus, the fixation plate can accommodate bone fasteners or load transmitting components having curved engagement surfaces of various diameters and providing varying degrees of rigidity. In another feature of the invention, a C-shaped ring (41) is provided which encircles the plate (21) to entrap the side walls (21a) of the plate, thereby restricting the plate walls from spreading as the bone screws or bolts are tightened onto the plate.

摘要： A spinal fixation system includes an elongated spinal rod (R) and a number of vertebral fixation elements (10), each including a vertebra engaging portion (11) and a rod engaging portion (13) formed by a pair of posts extending from the vertebra engaging portion. The vertebral fixation elements are engaged to the spinal rod each by way of a top-loading clamp (20) that permits access directly from the top of the instrumentation site for tightening the system. The clamp includes a body (21) defining an elongated bore (22) configured to receive the spinal rod (R) therethrough and a pair of threaded bores (29) from opposite top and bottom surfaces of the body, each intersecting the rod bore (22). The clamp further includes a projection (24) extending from the body terminating in a T-bar (26) having a clamping surface (27) directed inwardly toward the elongated bore configured to engage the pair of posts (14) of the vertebral fixation clement (10). A set screw (30) is threaded into one of the threaded bores (29) to bear against the spinal rod disposed within the rod bore.

摘要： A variable angle bone screw system for use in a spinal implant system to connect a vertebral fixation element to a spinal rod extending adjacent the vertebral column in a patient. The system includes an eyebolt having a threaded stem, a washer receivable over the stem of the eyebolt, a bone screw including a yoked head to permit top loading of the stem of the eyebolt, and a nut engaging the threaded stem of the eyebolt and cooperating with the eyebolt to clamp the bone screw and washer therebetween. The bone screw head and the washer include interdigitating locking means for restraining the pivoting of the screw about the axis of the eyebolt threaded stem but permitting interlocking in variable angular orientations.
