摘要： PROBLEM TO BE SOLVED: To provide a lordotic fusion device that can recover a lordosis and prevent dislocation. SOLUTION: An interbody fusion device 10 has a tapered main body 11 having a hollow interior that receives bone graft or bone substitute material. The main body 11 has discontinuous exterior thread members 18. The fusion device 10 has truncated sidewalls 22. The sidewalls 22 are provided with vascularization openings 24, 25 and the main body 11 is provided with bone ingrowth slots 27. An implant driver is engaged to the truncated sidwalls 22 to complete a cylindrical shape at the root of the exterior threads 18. The driver can easily insert the fusion device to an intra-discal space between vertebrae. When the fusion device 10 is inserted to a specified depth into the intra- discal space between the vertebrae, a normal lordosis of the vertebra level is recovered. A lordotic angle is restored not only by way of the taper of the device but also the depth of insertion of the device. The fusion device 10 can be inserted from an anterior or a posterior approach. The device 10 is screw threaded into a proper position in the anterior approach, and operates as a cam for enlarging the space between the vertebrae to recover the lordosis in the posterior approach.

摘要： PROBLEM TO BE SOLVED: To provide a template assembly to mark an adhesion device transplanting position through the smallest incision part. SOLUTION: A template assembly 15 is pivotally moved so that a position for the transplantation of an in vivo adhesion device or the introduction of a work instrument is marked on an intervertebral disk annulus. The template assembly 15 is introduced by stinging into the body, and has a tubular main body 17 having a dimension such as being advanced into a damaged intervertebral disk. A long and narrow shaft 19 engages by a screw with the main body on the base end by slidably extending on the inside of the tubular main body 17, and advances the shaft 19 through the main body by rotation of the shaft 19 related to the main body. A guide foot 21 is pivotally fixed to the tail end of the tubular main body 17, and is pivotally moved to a second unfolding position substantially vertically pointed to the tubular main body 17 from a first position fitting to the tubular main body 17 by advancing the shaft 19 through the tubular main body 17. The guide foot 21 has a bore, and a work tip of an electric cautery extends through this bore, and forms a mark on an intervertebral disk annulus.

摘要： A method for internal fixation of vertebra (10) of the spine to facilitate graft fusion includes steps for excising the nucleus of an affected disc, preparing a bone graft, instrumenting the vertebrae for fixation, and introducing the bone graft into the resected nuclear space. Disc resection is conducted through two portals (26a and 26b) through the annulus (15), with one portal supporting resection instruments and the other supporting a viewing device. The fixation hardware includes bone screws (30), fixation plates (40), engagement nuts (42), and linking members (44). In an important aspect of the method, the fixation plates, engagement nuts and linking members are supported suprafascially but subcutaneously so that the fascia (22) and muscle tissue (23) are not damaged. The bone screw (30) is configured to support the fixation hardware above the fascia (22). In a further aspect of the invention, a three component dilator system (50) is provided for use during the bone screw implantation steps of the method.

摘要： The eye and threaded shaft of an eyebolt (46) are formed by a combination of two shell-like portions (46A, 46B), each having threaded bosses (48A, 48B) at distal ends thereof. The distal ends are placed around a spinal rod (14) simultaneously with insertion of one of the shell-like portions through the yoke (27, 28) of a spinal hook (22). Then the bosses are brought toward each other and the two bosses combine to form a bolt onto which a nut (36) is threaded to clamp the eyebolt, and thereby the hook, tightly on a spinal rod. The two threaded bosses have an interfitting rib (51) and groove (49) to maintain alignment of the threads of the two bosses. The eyebolt of this invention allows a connecting hook to be installed on a spinal rod in situ between other devices already installed on the spinal rod.
