摘要： A template assembly is provided for marking locations on the disc annulus for the implantation of an interbody fusion device or the introduction of a working instrument. The template assembly includes a tubular body sized for percutaneous introduction into a patient and advancement to an affected intervertebral disc. An elongated shaft slidably extends through the tubular body and is threadedly engaged to the handle-mounted thumb wheel so that rotation of the thumb wheel relative to the tubular body retracts the shaft through the body. A guide foot with a rotatable cam near the distal end of the tubular body is operable by the shaft and may be pivoted from a first position aligned with the tubular body to a second deployed position oriented transversely to the tubular body. The guide assembly has an electrocautery projection for marking locations on the disc annulus.

摘要： A laparoscopic surgical technique is provided for preparing a site for implantation of a fusion device or implant. In accordance with one embodiment of the technique, a laparoscope is provided having an outer sleeve with distraction fingers at one end to distract the disc space. The laparoscope includes a laparoscopic port at its opposite end through which instruments and implants are inserted. The laparoscope provides a sealed working channel to the disc space, through which the disc space is distracted, the vertebral endplates and surrounding disc is reamed, and the fusion device inserted. The laparoscope is alternately engaged within bilateral locations in the disc space for insertion of a pair of fusion implants. A switching sleeve extends through the laparoscope to protect the tissue at the surgical site as the laparoscope is moved between the bilateral fusion locations.

摘要： A template assembly is provided for marking locations on the disc annulus for the implantation of an interbody fusion device or the introduction of a working instrument. The template assembly includes a tubular body sized for percutaneous introduction into a patient and advancement to an affected intervertebral disc. An elongated shaft slidably extends through the tubular body and is threadedly engaged to the tubular body at its proximal end so that rotation of the shaft relative to the tubular body advances the shaft through the body. A guide foot is pivotably connected to the distal end of the tubular body to be pivoted from a first position aligned with the tubular body to a second deployed position oriented substantially perpendicular to the tubular body. The guide body is pivoted from the first position to the second position by advancement of the elongated shaft through the tubular body. The guide body in one embodiment defines a bore through which the working tip of an electrocautery instrument extends to mark the disc annulus. In another embodiment, the guide body itself defines an electrocautery projection. The template assembly can be anchored to the affected disc by a guide wire extending through the tubular body and about which the template assembly can be rotated to make an additional mark on the annulus at a predetermined distance from the first mark.

摘要： An interbody fusion device in one embodiment includes a tapered body defining a hollow interior for receiving bone graft or bone substitute material. The body defines exterior threads which are interrupted over portions of the outer surface of the device. The fusion device defines truncated side walls so that on end view the body takes on a cylindrical form. The side walls are provided with vascularization openings, and the body wall device includes opposite bone ingrowth slots extending through the interrupted thread portion of the body. In another embodiment, the tapered body is solid and formed of a porous biocompatible material having sufficient structural integrity to maintain the intradiscal space and normal curvature. The material is preferably a porous tantalum having fully interconnected pores to facilitate complete bone tissue ingrowth into the implant. An implant driver is provided which engages the truncated side walls to complete the cylindrical form of the implant at the root diameter of the interrupted threads, to thereby facilitate threaded insertion of the implant to the intra-discal space between adjacent vertebrae. Methods for posterior and anterior insertion of the fusion device are also disclosed.

摘要： A laparoscopic surgical technique is provided for preparing a site for implantation of a fusion device or implant. In accordance with one embodiment of the technique, a laparoscope is provided having an outer sleeve with distraction fingers at one end to distract the disc space. The laparoscope includes a laparoscopic port at its opposite end through which instruments and implants are inserted. The laparoscope provides a sealed working channel to the disc space, through which the disc space is distracted, the vertebral endplates and surrounding disc is reamed, and the fusion device inserted. The laparoscope is alternately engaged within bilateral locations in the disc space for insertion of a pair of fusion implants. A switching sleeve extends through the laparoscope to protect the tissue at the surgical site as the laparoscope is moved between the bilateral fusion locations.

摘要： A method and instrumentation particularly adapted for disc space preparation from an anterior approach to the spine. In one aspect, an expandable template is provided having guides to guide a cutting device for bilateral formation of openings in the disc space. In another aspect, an improved guide member is provided for guiding a cutting tool. Still further, the invention provides an improved double barrel guide sleeve with a central distraction extension and lateral non-distracting extensions. Optionally, the guide sleeve includes windows and covers to selectively cover the windows. An improved reamer with an internal chamber and optional modular coupling is also provided. A depth stop is provided to selectively engage a tool shaft and a guide sleeve to control tool penetration into the disc space. A method of using the disclosed instruments is also provided.
