Disclosed is an assembly and method for implant installation between adjacent vertebral bodies of a patient. The implant has a support body and a rotatable insert therein and the support body is curved for installation between adjacent vertebral bodies transforaminally. An installation instrument is also disclosed for removable attachment to implant and engagement with the rotatable insert to selectively permit rotation between the insert and the support body. The installation instrument extends along a longitudinal tool axis and when the installation instrument is in a first position the insert is rotationally fixed with respect to the support body and when the installation instrument is in a second position the support body may rotate with respect to the insert.

The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may have a body and the body comprises one or more apertures. The apertures receive fixation elements, such as a screw and the like. The fixation element may comprise one or more anti-backout features, such as a split ring. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The apertures that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ. Some of the apertures may be configured to rigidly lock with the fixation elements. Moreover, the spinal implant may include features, such as one or more bores, that can accommodate imaging marks to help guide a surgeon.

Surgical kits comprising a tool having a handle and a shaft affixed to the handle at one end and a free end having a threaded connection, at least two disc inserts, each disc insert comprising a rounded square having an annular wall surrounding a top surface and a bottom surface, wherein a threaded catch is formed in each disc insert to mate with the threaded connection, and wherein the interface between the disc insert top surface and annular wall forms a first perimeter and the interface between the disc insert bottom surface and the annular wall forms a second perimeter. At least a portion of the disc inserts can be radiopaque and a portion can be radiolucent. Also provided are kits having one or more disc inserts and one or more trial plates, each trial plate comprising a plurality of positioning guides.

Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.

Devices and methods for fixing defects in the anulus fibrosus (vertebral disc) of a patient are described. The devices include a mesh patch, and first and second suture assemblies, each of which include an anchor and a suture. The anchor has a first portion adapted to be inserted into a bone and a second portion having an opening therethrough. The suture is adapted to be disposed through the opening and has a first end is adapted to couple to the mesh patch. The method of treatment includes inserting the first portion of the first anchor into a cranial vertebra and inserting the second portion of the second anchor into a caudal vertebra. The first ends of the sutures are attached to the mesh patch. The mesh patch is positioned adjacent the defect by pulling on, or applying tension to, the second ends of the sutures.

A modular interbody fusion device for fusing adjacent spinal vertebrae that is adapted to be implanted in a prepared interbody space including a first modular segment having a width including a first rail extending at least partially along one side of the width and beyond a periphery of a body portion of the first modular segment, a second modular segment having a width and slidably connected to the first rail on one side of the width and having a second rail extending at least partially along another side of the width and beyond a periphery of a body portion of the second modular segment, a third modular segment having a width and slidably connected to the second rail on one side of the width and wherein the device has an expanded position and an implanted position in which the modular segments are combined to mimic the shape of the vertebra.

An intervertebral prosthesis for insertion by posterior approach, designed to be inserted in pairs between two vertebral bodies, said prosthesis consisting of a prosthesis body extending in a longitudinal direction of intervertebral insertion, including peripheral faces delimiting, on the inside, an inner space for receiving a bone substitute. The prosthesis includes a prosthesis body of which the lower and upper bearing faces have a convex profile having continuously variable convexity in the longitudinal direction. The invention is intended for the treatment of individuals suffering from disc degeneration in the thoracic or lumbar vertebrae.

A medical having a proximal and a distal end, that is preformed to assume a superimposed structure at an implantation site but can be made to take on a volume-reduced form making it possible to introduce it by means of a micro-catheter and a guide wire arranged at the proximal end, with the implant in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments. The implant has a tapering structure at its proximal end where the strings or filaments converge at a connection point.

A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.

The present invention relates generally to medical devices, systems, and methods for use in surgery. In particular, the disclosed system and methods relate to an intervertebral spinal implant sized and dimensioned for the lumbar spine implantable via a posterior approach. The system includes an implant, instruments for delivering the implant.
