A system for implanting an interbody device between adjacent vertebrae comprises an interbody device having a plurality of lobes extending outwardly from a longitudinal rib, and having a relaxed shape approximating the shape of the disc being replaced. An insertion guide has a bore therein from a proximal end to a distal end thereof to accept the interbody device in an unrelaxed shape. The distal end is shaped for insertion into an intervertebral space. The insertion rod may be positioned within the bore of the insertion guide whereby the interbody device is positioned within the intervertebral space by advancing the insertion rod into the insertion guide.

An expandable interbody spacer (10) is provided that includes a pair of oppositely facing endplate components (20, 40) and an interior component that includes one or more vertically extending stacks of arranged C-clip members (70) radially surrounding one or more bosses (30) protruding interiorly from one of the endplates, wherein the size and configuration of the bosses and the C-clip members are designed to allow the incremental expansion of expandable interbody spacer.

In some embodiments, the present disclosure relates to a system that includes an insertion tool and a drill guide. The insertion tool includes a body with a distal portion and a distal end. The body has a first engagement feature extending longitudinally along the distal portion and two arms extending longitudinally from the distal end of the body. The drill guide includes two bores and an open faced channel therebetween. The open faced channel includes a second engagement feature slidably engageable with the first engagement feature on the body of the insertion tool. The two bores are adapted for the disposal of a fastener driver tool therethrough.

The present disclosure includes implant systems, devices, and implants. The interbody spacers including a first endplate, a second endplate, and a coupling member coupled to and extending between the first endplate and the second endplate. Methods of using the interbody spacers are also disclosed.

In some aspects, a device comprising an implant configured for insertion into a portion of human anatomy, and at least one covering coupled to the implant is provided. According to some aspects, the implant comprises one or more protrusions configured to prevent leakage of material and/or to resist displacement of the implant. According to some aspects, the covering is configured to facilitate improved leakage and/or implant displacement prevention.

A spinal implant includes a first member having a wall that defines an axial cavity. A second member extends between a first end and a second end and defines a longitudinal axis. The second member is configured for disposal with the axial cavity and translation relative to the first member. A third member has an outer surface engageable with tissue and an inner surface disposed to dynamically engage the first end in response to the engagement of the outer surface with the tissue. Systems and methods are disclosed.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine and methods for inserting said discs. The intervertebral prosthetic discs are provided with connections for facilitating implantation and removal and features which enhance primary and secondary stability over time.

Proposed is a spinal cage. The spinal cage includes a bone support portion configured to be disposed between a first vertebra at an upper side and a second vertebra at a lower side to support the first vertebra, a base portion positioned at a lower side of the bone support portion to come in contact with the second vertebra, and a sidewall portion which has an upper side end connected to an edge of the bone support portion and a lower side end connected to an edge of the base portion and includes an elastic band having elasticity and inelastic bands having relatively lower elasticity or no elasticity. Therefore, subsidence of the spinal cage into vertebrae can be suppressed.

An intervertebral implant that iterates between collapsed and expanded configurations includes first and second plates spaced from one another along a first direction and defining bone-contacting surfaces facing away from each other along the first direction. An expansion assembly is positioned between the plates with respect to the first direction and includes a first support wedge that supports the first plate and defines a first ramp and a second support wedge that supports the second plate and defines second and third ramps. The expansion assembly includes an expansion wedge defining a fourth ramp. The first, second, third, and fourth ramps are each inclined with respect to a second direction that is substantially perpendicular to the first direction. At least one of the first and second support wedges is slidable along the respective supported first or second plate. The implant includes an actuator configured to apply a drive force to the expansion wedge so as to cause 1) the fourth ramp to ride along the third ramp so as to increase a distance between the bone-contacting surfaces along the first direction, and 2) the second ramp to ride along the first ramp, thereby further increasing the distance, thereby iterating the implant from the collapsed to the expanded configuration.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants with detachable fixation tabs.
