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

A spinal implant system comprises a plate including a surface that defines a first cavity and a second cavity. The first cavity is oriented to implant a multi-axial fastener with a sacrum. The second cavity is oriented to implant a fastener with an ala of a sacrum. A surgical instrument is engageable with the plate. At least one of the plate and the surgical instrument includes an engagement surface for connection therebetween. Systems and methods of use are disclosed.

Spinal implant system and method

A spinal implant for use with a surgical treatment comprises a plate including a surface that defines a first cavity and a second cavity. The first cavity is oriented to implant a multi-axial fastener with a sacrum. The second cavity is oriented to implant a fastener with an ala of a sacrum. Systems and methods of use are disclosed.

An implant system comprises a fastener including a proximal portion including an inner surface that defines a first cavity that defines a first axis and a distal portion configured for penetrating tissue and defining a longitudinal axis disposed transverse to the first axis. A connector extends between a first end and a second end configured for disposal in the first cavity. A receiver is attachable to the first end and includes an implant cavity defining a second axis. The implant cavity is rotatable about a third axis disposed transverse to the second axis such that an implant disposed in the implant cavity and lateral to the first end is rotatable in a first plane relative to the first end in a configuration for selective fixation with the first end. Methods of use are disclosed.

Vertebral implant and connector

An orthopedic bone anchor device is disclosed that includes, in one embodiment, a receiver member, an anchor member and a retaining member. The retaining member may retain the anchor member at least partially in the receiver member. In certain embodiments, the anchor member may have a groove in a head for accommodating part of the retaining member, and/or a multiple lead thread.

Multiple lead bone fixation apparatus

A connecting device is provided for use in orthopedic surgery, for example to connect a spinal rod and a vertebral screw or hook. The connector generally includes a receiver member for receiving an elongated member, and a grommet member for receiving a bone fixation member. The grommet member is inserted into the receiver member so that the receiver member and grommet member are rotatably connected. One or more disks may be placed between the receiver member and grommet member to assist in locking the device.

Grommet assembly

One nonlimiting embodiment is directed to an anchor extender releasably engaged with an anchor configured for engagement with one or more bones or bony portions. The anchor extender generally includes a first member and a second member positioned about and movable relative to the first member. The anchor extender is positionable adjacent the anchor and movement of the second member relative to the first member toward the anchor as the anchor extender is engaged with the anchor results in lateral displacement of the anchor extender relative to the anchor while the first member engages with a first side of the anchor and the second member engages with an opposite second side of the anchor. However, in other embodiments, different forms and applications are envisioned.

Anchors extender assemblies and methods for using

An instrument is provided for reduction of a rod or other elongated member into an implant, such as a bone screw. In one embodiment, such an instrument includes a rod adjusting assembly pivotably attached to an implant holding assembly. The implant holding assembly can be pivotably connected to an implant, and the rod adjusting assembly is operable to move a rod toward or away from the implant holding assembly. In that embodiment, several motions are possible by the instrument so that relatively small or large movements of a rod with respect to an implant may be made.

Reducing instrument for spinal surgery

A connecting device is provided for use in orthopedic surgery, for example to connect a spinal rod and a vertebral screw or hook. The connector generally includes a receiver member for receiving an elongated member, and an grommet member for receiving a bone fixation member. The grommet member is inserted into the receiver member so that the receiver member and grommet member are rotatably connected. One or more disks may be placed between the receiver member and grommet member to assist in locking the device.

A connector apparatus for linking spinal rods comprises a connector body having a C-shaped engagement portion contiguous a closed engagement portion. The engagement portions each include an opening to receive a rod, each opening including an inner contact surface to engage the rod. Additionally, each engagement portion includes a through-hole to receive a screw, the through-holes being aligned substantially perpendicular to a longitudinal axis of the connector body. The through-hole and screw corresponding to the C-shaped engagement portion are offset from the corresponding rod when the rod is positioned in the corresponding opening. Additionally, the screws are advanced through the through-holes to urge the rods against the inner contact surfaces to engage the connector body to the rods. The connector apparatus creates a low profile, top tightening fixation system, providing a stable, rigid transverse connection between adjacent spinal rods.

Connector apparatus

An apparatus for connecting an implant with a rod comprises a body, a collet, an annular ring member, a washer, and a nut. The body defines a first channel to receive the rod and a second channel extending through the body. The collet is positionable in the second channel and defines an aperture for receipt of the implant. The ring member includes a gap and defines an aperture for receipt of the collet. The washer is positionable adjacent the second channel and is configured to translate along the body to allow pivoting of the collet relative to the body. The nut is operable to connect with the collet to move the collet within the second channel. Movement of the collet is operable to expand the ring member and contract the collet around the implant to secure the implant at a desired position.

Open dorsal adjusting connector

A connector assembly includes a coupling body for securing an elongate member to an implant engaged to the spinal column. The elongate member is offset to one side of and transversely oriented to the implant. The coupling body includes a first passage for receiving the implant and a second passage for receiving the elongate member and a clamping member positioned about the elongate member. The coupling assembly also includes an engaging member that engages the coupling body and contacts the clamping member to clampingly engage the elongate member with the clamping member while manipulating the coupling body positioned about the implant to engage the coupling body to the implant.

Dorsal adjusting spinal connector assembly

A spinal stabilization apparatus and method according to which a fastener is engaged with a vertebra of a spinal system. The fastener is connected to a rod and the direction of extension of at least a portion of the rod in a coronal plane may be selectively adjusted.

Spinal stabilization apparatus and method

An apparatus for use in orthopedic distraction or compression is disclosed. In the illustrated embodiments, two arms are provided that are connected by a rod or bar with a mechanism that enables the arms to be brought toward or away from each other. At the end of each arm, an assembly for connecting to a bone implant is provided. The assemblies are pivotable with respect to the arms, and allow some rotational motion between parts of the assembly so as to accommodate different positions of the bone implants. Once the assemblies are appropriately positioned, connected and locked to the bone implants, the mechanism can be operated to move the arms together in compression or apart in distraction.
