In a general aspect, an apparatus can include a plate configured for implantation in a body of a patient. The plate can include a plurality of pores and be configured for placement between a cancellous bone of a spinal vertebra and a corresponding cartilaginous endplate as a replacement for a bony endplate of the spinal vertebra.

Intervertebral endoprosthesis discs suitable for surgical implantation between two vertebrae having and methods thereof. The prosthetic disc may have an endoprosthesis body including an anterior region and a posterior region designed to be positioned between a first vertebra and a second vertebra with a first and second movable insert positioned rotatably in anterior cavities and is rotatable to adjust the fasteners.

Embodiments are directed to spinal treatments and, more particularly, to a trial inserter tool compatible with detachable trial heads for use in spinal surgery. In a preferred embodiment, the present invention provides a system for sizing an implant to be used in posterior lumbar interbody fusion surgery. The system may comprise a trial inserter tool, wherein the trial inserter tool comprises: a body, wherein the body is an elongated tubular, wherein the body comprises a first end and a second end; an actuation device, wherein the actuation device is disposed on the body between the first end and the second end; and a hooked support member that extends from the second end of the body; and a trial head disposable on the hooked support member.

The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation and or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing and or stabilizing a plurality of bones is provided. The system includes an implant structure having a shank portion, a body portion and a head portion. The body portion is coupled to the shank portion and is configured to be placed through a first bone segment, across a bone joint or fracture and into a second bone segment. The body portion is configured to allow for bony on-growth, ingrowth and through-growth. The head portion is coupled to the proximal end of the shank portion and is configured to couple the shank portion to a stabilizing rod. Methods of use are also disclosed.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

The present disclosure pertains to ionic polymer compositions, including semi- and fully interpenetrating polymer networks, methods of making such ionic polymer compositions, articles made from such ionic polymer compositions, and methods of making such articles and packaging for such articles.

Intervertebral spacer assemblies, systems, and methods thereof. A method of insertion includes inserting an intervertebral spacer and plate together using an insertion tool and, upon removal of the insertion tool, the intervertebral spacer and plate are no longer considered connected/coupled and act as separate components.

A disc implant device can be provided in a generally planar rectangular sheet having a first elongated side, a second elongated side opposing the first elongated side, a first end, and a second end opposing the first end. The generally planar rectangular sheet is structured with alternating segments of joint ridges, each segment of joint ridges being configured to form a spacing joint segment and alternating segments of arm ridges, each arm segment being configured to form a plurality of radially extending arms, the joint segments providing flexibility to the device. When the disc implant is folded or rolled from its planar configuration to a generally cylindrical configuration, the arm segments are axially collapsible and radially expandable such that in such a configuration, the implant includes segments of radially expanded arms separated by spacing joint segments.

An apparatus and method for joining members together using a self-drilling screw apparatus or stapling apparatus are disclosed. The screw apparatus includes a worm drive screw, a spur gear and superior and inferior screws which turn simultaneously in a bi-directional manner. A rotating mechanism drives the first and second screw members in opposite directions and causes the screw members to embed themselves in the members to be joined. The screw apparatus can be used to join members such as bones, portions of the spinal column, vertebral bodies, wood, building materials, metals, masonry, or plastics. A device employing two screws (two-in-one) can be combined with a capping horizontal mini-plate. A device employing three screws can be combined in enclosures (three-in-one). The stapling apparatus includes grip handles, transmission linkages, a drive rod a fulcrum and a cylinder. The staple has superior and inferior segments with serrated interfaces, a teethed unidirectional locking mechanism and four facet piercing elements. The staples can be also be used to join members such as bones, portions of the spinal column, or vertebral bodies.

An implant stabilizes two adjacent bones of a joint, while enabling a natural kinematic relative movement of the bones. Support components are connected to each bone of the joint, and a flexible core is interposed between them. The core and at least one of the support components are provided with a smooth sliding surface upon which the core and support component may slide relative to each other, enabling a corresponding movement of the bones. The surfaces may have a mating curvature, to mimic a natural movement of the joint. The core is resilient, and may bend or compress, enabling the bones to move towards each other, and or to bend relative to each other.
