Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. The implant or a portion thereof may be composed of a shape-memory material, which has a curved shape-memory orientation and a temporarily straight orientation. The implant may be configured to be inserted into a pedicle of an inferior vertebra, through the vertebral body of the inferior vertebra, and into the vertebral body of the superior vertebra to thereby stabilize the inferior and superior vertebrae.

The present disclosure relates to a delivery device and screw combination. The combination includes a delivery device comprising a handle and a shaft coupled to the handle, the shaft including a proximal end, a distal end, a non-circular cannulation, and markings along a length of the shaft; an interference screw coupled to the delivery device comprising a proximal end and a distal end, the screw including threads extending in an open helical form from the proximal end to the distal end, a suture bridge located at a distal end of the screw and housed within a slot of the delivery device shaft, and a plurality of runners extending longitudinally along an interior of the screw, the runners housed within grooves of the delivery device shaft; and a suture disposed around the suture bridge, ends of the suture extending through the cannulation of the delivery device shaft.

A woven retention device for interfacing with a bone surface includes a sleeve body that can surround a fastener, a proximal end receiving the fastener, and a distal end. The sleeve body includes interwoven monofilaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. In a first state of the sleeve body, the protuberances are arranged in a predetermined spatial relationship and each protuberance has a thickness measured in a radial direction of the sleeve body. In a second state when a fastener is inserted into the tubular lattice, pressure from the fastener is transmitted to the tubular lattice such that the spatial relationship of the protuberances changes according to a function of bone density and according to a function of an interfacing surface shape of the fastener.

Compression devices for joining tissue and methods for using and fabricating the same.

The present disclosure relates to an interference screw for creating an interference fit between a bone tunnel and tissue. The screw includes a threaded body having a proximal end, distal end, and thread extending around the threaded body between the proximal and distal ends. A supporting spline extends along a cannulation through the threaded body. The supporting spline is engagable with a delivery device. The screw further includes at least one opening defined by a surface between threads of the threaded body. A ratio of open surface area to closed surface area defines the opening and is selected such that, when torsionally loaded, the screw does not exhibit plastic deformation when inserted into an undersized bone tunnel. The screw further includes a tapered tip extending from the distal end of the threaded body. The tapered tip has a thread extending at least partway around the tapered tip.

A bone anchor includes an anchor member including a first material, and having a tubular section extending along a longitudinal axis, a region configured to expand radially outwards from the longitudinal axis, and a bone engagement structure projecting from at least a portion of the expandable region of the tubular section, and a core member including a second material, and configured for insertion into and connection to the anchor member. When the core member is in the anchor member and is actuated relative to the anchor member, the tubular section is adjustable between a first position where the expandable region of the tubular member has a first length and a first maximum diameter, to a second position where the expandable region of the tubular member has a length shorter than the first length and a maximum diameter greater than the first maximum diameter.

A bone screw includes a shaft including at least one thread having an external thread form and defining at least one cavity. The shaft includes at least one tissue gathering member disposed to direct tissue into the at least one cavity. In some embodiments, systems, spinal constructs, surgical instruments and methods are disclosed.

Embodiments of the present invention relate to systems, methods, and apparatus for immobilizing and/or securing bone portions. Particularly, at least one embodiment involves a compact anti-rotation device that can secure adjacent bones and/or bone portions in a manner that prevents or limits relative rotational movement thereof.

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 surgical tool, comprising a needle comprising an aperture of sufficient diameter for receiving a screw; a tool, insertable into said aperture for inserting said screw and capable of engaging with and turning the screw; said screw comprising a shaft having threads in a first direction, a head having a bottom face having a flange, and a coil; said coil wound around the screw shaft in an opposing second direction as to the first direction; said coil comprising a coil end which is defined to engage with the flange on the bottom face.
