Various multiaxial receivers for receiving at least one tether are disclosed. A multiaxial receiver may include a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw. The body may include a first aperture extending through a side surface of the body and defining a first passageway configured to permit a tether to pass therethrough in the horizontal direction. In some embodiments, the body may include a second aperture extending through the side surface of the body and defining a second passageway configured to permit the tether to pass therethrough in the horizontal direction. A set screw may be configured to be rotated from an open position in which the tether is permitted to pass through the first passageway and optionally through the second passageway to a closed position in which the tether is immobilized.

Multiaxial receivers with tether

An interbody system including an implant and a tool for inserting and expanding the medical implant and locking the implant in place is disclosed. The medical implant may include an expandable body defined by a superior endplate and an inferior endplate that are hingedly coupled and may be expanded and lordosed. The superior and inferior endplate may include radially disposed and opposed surfaces that mate and/or directly contact each other when a locking screw is threaded through a screw aperture. The implant may include a threaded breakoff screw disposed in the threaded screw aperture and movable between a locked position and an unlocked position, for example. In the locked position, the threaded locking screw may urge the distal engagement surface of the first core into direct contact with the proximal engagement surface of the second core. When broken, the breakoff screw may comprise a recessed fracture surface.

Expandable interbody implant and corresponding surgical tool

Implants, devices, systems and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

Implants, systems, and methods of use and assembly

An expandable implant may include an expandable body defined by a superior endplate and an inferior endplate that are hingedly coupled and may be expanded and lordosed by an external surgical tool. The superior endplate may include a first core having a distal engagement surface and the inferior endplate may a second core having a proximal engagement surface and a threaded screw aperture. The implant may include a threaded locking screw disposed in the threaded screw aperture and movable between a locked position and an unlocked position, for example. In the locked position, the threaded locking screw may urge the distal engagement surface of the first core into direct contact with the proximal engagement surface of the second core. The implant may include a pair of mounting tangs that may be sheared off and/or recesses. The locking screw may be a break-off screw.

Expandable interbody implant and corresponding inserter

An implant system comprising a staple and a cage is disclosed. The implant system is secured to the bone by moving the staple rotationally and longitudinally whereby tines of the staple and opposing tines frictionally and mechanically engage or embed themselves in the bone side walls. For vertebral applications, the cage defines an upper surface plane, a lower surface plane and a cage surface angle between these two planes whereby the cage surface angle may alter an endplate surface plane of one or more vertebral body when the cage is implanted in a vertebral body. Implant systems may be configured for use as an interbody or intrabody implant system. The implant system may also be configured for use in arthrodesis procedures with other joints within the body. The implant system may further comprise an anchor frame or plate to further secure the cage and staple to the anatomy.

Implant system and methods of use

Systems and methods for tibial plateau leveling osteotomy (TPLO) are disclosed. According to some embodiments, an osteotomy method may include cutting a tibia with an arcuate cut to separate a tibial plateau of the tibia from a tibial base of the tibia, rotating the tibial plateau relative to the tibial base from a first orientation to a second orientation, and, with the tibial plateau in the second orientation relative to the tibial base, securing an implant to the tibia to secure the tibial plateau to the tibial base. Securing the implant to the tibia may include embedding a first leg of the implant into the tibial base, and embedding a second leg of the implant into the tibial plateau such that the first and second legs apply compression urging the tibial plateau toward the tibial base.

Tibial plateau leveling osteotomy systems and methods

A multiaxial receiver may include a body having a U-shaped cavity configured to receive a longitudinal rod therein and a lower cavity configured to couple to a pedicle screw. The multiaxial receiver may include a first passageway configured to permit a tether to pass therethrough in the vertical direction. In some embodiments, the multiaxial receiver may also include a second passageway configured to permit a tether to pass therethrough in the horizontal direction. An immobilization assembly including a set screw and a wedge may immobilize the tether. The immobilization assembly may be configured to be rotated from an open position in which the tether is permitted to pass through the first passageway to a closed position in which the tether is immobilized within the first passageway or second passageway by pining the tether against a bearing surface of the first passageway.

A unibody implant movable between an expanded position and a contracted position is disclosed. The unibody implant may include a unitary expandable body defined by an inferior portion and a superior portion that are connected together. In various embodiments, a set screw may be rotatably supported by the body and configured to move a plug having a first inclined surface facing the distal side. In various embodiments, the set screw may be movable in the longitudinal direction towards the distal side upon rotation of the set screw along the rotation axis, for example. In various embodiments, movement of the set screw urges the plug against the superior portion thereby expanding a vertical distance between the superior and inferior sides of the body. In some embodiments, the plug may include a stabilizing element configured to transfer compressive forces between the superior portion and inferior portion.

Monoblock expandable interbody implant

An expandable implant having superior and inferior endplates disposed on opposite sides of a core is disclosed. The superior endplate may include a first screw engagement surface disposed on a proximal end thereof and the inferior endplate may include a second screw engagement surface disposed on a proximal end thereof. A pin may extend through corresponding pin apertures of the superior endplate, the inferior endplate, and the core. In various embodiments, the superior endplate and inferior endplate are hingedly connected to the core via the pin. The implant may include a locking screw movable between a locked position and an unlocked position. In the locked position, the locking screw may urge an engagement surface of the superior endplate and inferior endplate such that corresponding interior surfaces of the superior and inferior endplates frictionally engage against a corresponding exterior surface of the core.

Expandable interbody implant

Implants, devices and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

Implants and methods of use and assembly

A translating polyaxial bone anchor for anchoring a connecting rod to a spinal vertebra comprises a fastener having a bone engaging portion and a head, the head defining a socket. An insert is captively retained in the socket and configured for swiveling polyaxial movement therein. The insert includes an elongate connecting element defining an axis, the connecting element projecting outwardly from and through the socket. A yoke having at one end a rod receiving channel for receiving a connecting rod is coupled to the fastener by a coupling member. The coupling member couples the yoke to the insert connecting element for joint polyaxial movement relative to the fastener and for translational movement of the yoke in a direction transverse to the axis of the connecting member. A fastening element is supported by the yoke for securing the connecting rod between the fastening element and the coupling member.
