A surgical guide comprises a member including an inner surface defining at least one cavity configured for disposal of at least one surgical tool and at least one part movable relative to the member and including a lock element engageable with a lock element of a spinal implant. Systems and methods are disclosed.

Surgical instrument system and method

A surgical guide comprises a member including an inner surface defining a cavity configured for disposal of at least one surgical instrument. The member further includes at least one locking element configured for mating engagement with a spinal implant such that the member is rotatable relative to the spinal implant to selectively orient the at least one surgical instrument. Systems and methods are disclosed.

An apparatus comprises a pair of bone attachment devices and a crosslink device for a spinal fixation system or other implant arrangement. The bone attachment devices include a head with socket to receive a spinal rod or other elongate element and the crosslink device includes a pair of bridging members each having an end section for connecting with the bone attachment devices. An interconnection device situated between the bridging members receives the bridging members and allows translational and rotational freedom therebetween while being operable to secure the bridging members in position relative to one another. A pair of engaging members are structured to engage the head of the respective bone attachment device and bear against the respective adjacent end of crosslink device to lock the crosslink and the bone attachment device in a rigid construct are also included.

Crosslink interconnection of bone attachment devices

A connector apparatus for use in orthopedic procedures includes a base portion and an extending leg portion that forms a channel. Part of the base portion can be placed atop or adjacent implanted fixation members (e.g. bone screws), and a locking member can be inserted through the base and into the fixation member to anchor the connector to the fixation member. A rod can be inserted into the channel and fixed to the connector by a set screw. The apparatus is useful in connecting a rod to a fixation member, particularly in situations in which a rod is already connected to the fixation member, as by a previous implantation procedure, for example.

Orthopedic revision connector

An occipital plating system includes a fixation assembly with a plate and a coupling member extending from a respective one of opposite lateral portions of the plate. The coupling members include a channel to receive a connecting element extending from the spinal column. The coupling members are rotatable and translatable relative to the plate.

Translational occipital vertebral fixation system

Embodiments of an orthopedic implant assembly include an apparatus having a receiver member and a fixation member. The receiver member includes first and second branches which define a channel extending along a longitudinal axis. The channel is configured to receive an elongated member. Additionally, the fixation member can include a threaded portion configured to engage bone. The orthopedic implant system can further include a one-step locking mechanism operably connected with the receiver member, the locking mechanism being configured to lock an elongated member in the channel. The locking mechanism includes a first closure device operably connected with the first branch and a second closure device operably connected with the second branch. The first and second closure devices are configured to cooperate with each other along a lateral axis to lock an elongated member in the channel. In certain embodiments, the lateral axis does not intersect the longitudinal axis.

Orthopedic implant assembly

Orthopedic constructs having parts that are movable with respect to each other and one or more friction members to limit unintended movement are disclosed. In one embodiment, a multi-axial bone anchor having a receiver member and a screw-type anchor is provided. The receiver member includes one or more internal apertures in which a friction member is placed, and a portion of the anchor contacts or is loosely held by the friction member(s).

Multi-axial bone attachment member

A pair of bone attachment devices and a crosslink device for a spinal fixation system or other implant arrangement is provided that extends between and engages the bone attachment devices with engaging members. The bone attachment devices include a receiver portion and the crosslink device includes a pair of elongated bridging members each having a pivotally attached connector for connecting to the bone attachment devices at various planar elevations. An interconnection device situated between the connectors receives the members and allows translational and rotational adjustment of the members relative to one another.

Methods and devices for the interconnection of bone attachment devices

An occipital plating system includes an occipital plate extending along a medial-lateral oriented axis when engaged to the occiput. The plate body includes a housing portion and at least one wing portion extending from the housing portion that is adjustable relative to the housing portion along the medial-lateral axis. The plate body further includes receiving members mounted to the plate body that receive connecting elements extending along the spinal column to the occiput.

Occipital plating systems and methods

A quick attachment apparatus for use in association with orthopedic instrumentation and/or tools for releasable connection to a device, including a coupling member defining a passage extending generally along a longitudinal axis and sized to slidably receive a connection portion of the device, a locking member transitionable between a locked position and an unlocked position, a biasing member engaged between the coupling member and the locking member to bias the locking member into engagement against the connection portion to substantially prevent relative axial movement between the coupling member and the connection portion, and wherein application of a lateral force onto the locking member results in displacement of the coupling member generally along a transverse axis wherein the locking member is disengaged from the connection portion to allow relative axial movement between the coupling member and the connection portion.
