    摘要: A multi-lumen mold is for the in situ formation of a prosthesis in an annulus located in an intervertebral disc space of a patient. The annulus has at least two openings formed by minimally invasive techniques and at least a portion of the nucleus pulposus is removed to form a nuclear cavity. The multi-lumen mold includes a mold adapted to be located in the nuclear cavity. A first lumen having a distal end is fluidly coupled to a flexible mold at a first location. At least a second lumen having a distal end fluidly coupled to the flexible mold at a second location. The first and second lumens are adapted to extend out through the openings in the annulus when the mold is positioned in the nuclear cavity. One or more securing members can be used to secure the mold in the intervertebral disc space. The securing members can engage with the annulus, the end plates, and/or another surface of a vertebrate.

    摘要: A plurality of differently configured bone spinal implants for insertion in a spine have a cylindrical bore for receiving an insertion head stud. A plurality of instruments are disclosed each of which have a first connection element which is either a male or female member such as e.g., a ball and socket, a cylinder and socket and so on for forming either a stationary or articulating interchangeable joint for a plurality of disc processing heads or implant insertion heads. The plurality of disc space processing heads or implant insertion heads have a complementary second joint member for interchangeable attachment to the first connection element. The implant insertion heads or disc processing heads have different configurations for different shaped implants. Different instrument insertion or disc processing heads such as implant inserters, impactors, rasps, distractors, curettes, rongeur, and so on are disclosed as being interchangeable with a common instrument in which articulating or fixed joints are provided the interchangeable heads.

    摘要: A nuclectomy method for creating a nuclear cavity in an annulus located in an intervertebral disc space and for preparing the nuclear cavity to receive an intervertebral prosthesis. An annulotomy is formed in the annulus along an annular axis to provide access to a nucleus. A portion of the nucleus is removed in a first region surrounding the annular axis using at least a first surgical tool. Another portion of the nucleus is removed from a second region using at least a second surgical tool. An evaluation mold is positioned in the nuclear cavity and a fluid is delivered to the evaluation mold so that the mold substantially fills the nuclear cavity. The amount of nucleus removed from the annulus is estimated. One or more of the removing steps are optionally repeated as necessary until an adequate amount of the nucleus is removed from the annulus.

    摘要: A chisel with U.V-shaped, saw tooth or other shaped opposing blades is used to form channels in adjacent vertebrae. The chisel has a projection extending from at least one of the top and bottom surfaces to limit depth of penetration into the vertebrae. A guide member may be attached to the forward tip of the chisel to guide the chisel into the disc space to uniformly chisel both adjacent vertebrae simultaneously to form a channel in the vertebrae. The so formed channels serve as sa guide for a second chisel having no guide member. The second chisel, which may be a box chisel, is used to complete the channels to the desired depth to receive an associated implant, typically of cortical bone. Other embodiments are disclosed in which a two step box chisel has a retractable guide member for initially guiding the chisel as it forms partial channels in the vertebrae disc space. The guide member is then retracted and the channels formed to the desired depth. The chisels include guide member pins which serve to both limit the extension and retraction of the guide member and also to serve to limit the depth of penetration of the chisel, physically and visually. The guide member may be retracted with a rotatable knob and a threaded engaged rod or with an axially displaceable pin and rod assembly attached to the guide member. A procedure for using the chisels is also disclosed.
