An expandable implant includes a lower support; an upper support pivotally coupled to the lower support and including a control channel; and a control assembly. The control assembly includes a control shaft coupled to the lower support and a control member coupled to the control shaft and configured to move along the control shaft. The control member includes a base member and a pivot member pivotally coupled to the base member, the pivot member configured to move within the control channel. Movement of the control member along the control shaft causes the pivot member to pivot relative to the base member, and the upper support to pivot relative to the lower support.

Expandable implant with pivoting control assembly

A steerable expandable implant having a lower support member and an upper support member, the upper support member movable relative to the lower support member between a collapsed position and an expanded position. The implant also includes a first control member coupled to the lower support member, where manipulation of the first control member causes the lower support member to move relative to the upper support member. The implant further includes a pivot member configured to receive a tool, the tool and the pivot member rotatable relative to the lower support member between a first position and a second position, where the pivot member includes an aperture and an axis of the aperture is angularly offset from an axis of the first control member in the first position and the axis of the aperture is angularly aligned with the axis of the first control member in the second position.

Steerable implant assembly

An expandable implant includes an upper portion configured to engage a first portion of bone, a bottom portion configured to engage a second portion of bone, a control assembly coupled to the upper portion and the bottom portion and configured to control relative movement between the upper portion and the bottom portion, wherein the control assembly includes a front portion and a control member, wherein the front portion has an aperture configured to receive the control member, wherein the control member includes a head, and wherein a portion of the head is positioned outside of the aperture as the implant is expanded between a first, collapsed orientation and a second, expanded orientation.

Expandable implant assembly

A retractor includes a body, a first handle pivotally coupled to the body, a first attachment assembly comprising a first button configured to allow detachment of a second handle portion from the first handle, a first arm assembly attached to the first handle, a first blade attached to the first arm assembly, wherein the first handle is configured to control distraction of the first blade in response to pivotal motion of the first handle, a second handle pivotally coupled to the body, a second attachment assembly comprising a second button configured to allow detachment of a fourth handle portion from the second handle, a second arm assembly attached to the second handle, and a second blade attached to the second arm assembly, wherein the second handle is configured to control distraction of the second blade in response to pivotal motion of the second handle.

Orthopedic retractor

A spine implant for receipt between and fastened to a lower vertebra and an adjacent upper vertebra is characterized by an expandable cage and an expandable plate attached to the expandable cage. When the expandable cage is expanded, both the expandable cage and the expandable plate expand together at a uniform rate of movement. Engagement features of the expandable cage cooperate with engagement features of the expandable plate such that expansion of the expandable cage carries the expandable plate along during its expansion. The engagement features of the expandable cage may be configured as notches, cavities, or recessed pockets, while the engagement features of the expandable plate may be configured as tangs, flanges, or protuberances styled to be received by the configured notches of the expandable cage. Cam locks on the expandable plate help bone fastener backout.

Spine implant with an expandable cage and expandable vertebral attachment plate

A lateral spine implant has a plate, configured bone screws, and configured setscrews providing locking of bone screw movement. The plate has at least two identically configured bone screw bores, each one with a spherical seat at a bottom opening, and threads around the inner circumference of a top opening. Each setscrew has a cylindrical body with external threads that mate with inner threads of the bone screw bore in order to affix the setscrew to the plate. A threaded spherical pocket is provided in a bottom of the setscrew body which conjoins with the spherical bone screw head to secure the setscrew with the bone screw head, fixing bone screw orientation/angulation. The bone screw head has a formation or formations about at least a portion of its exterior circumference that cooperate with the threads of the spherical pocket of the plate in order to fix bone screw orientation/angulation.

Lateral spine plate with set screw locking of bone screws

An orthopedic implant has a plate and bone screws. Configured bone screw pockets of the plate provide variable angling and positional locking of a received bone screw relative. Each bone screw includes distal threads, a neck, and a dual threaded head. The plate has a bone screw pocket on a distal end, a bone screw pocket on a proximal end, and a strut extending between the two bone screw pockets. The bone screw pockets are at least generally cup shaped for receipt of a bone screw. The lower periphery of the opening of each bone screw pocket has an arrangement of configured prongs with configured openings to receive threading on the underside of the dual threaded head of the bone screw. The prongs can preferably, but not necessarily, deform slightly and grab onto the threading of the bone screw head to lock the bone screw in the bone screw pocket. Each prong can act independently.

Orthopedic implants with variable angle bone screw locking

A spine plate implant utilizes cam lock setscrews to retain bone screws in the plate once implanted. A cam lock setscrew is received in a setscrew pocket adjacent a configured bone screw bore of the plate and is configured to allow a bone screw to be received in the plate when in an unlocked rotational position, and to retain the received bone screw when in a locked rotational position. The bone screw may include a tang that allows engagement with external teeth of the cam lock setscrew when the cam lock setscrew is rotated into the locked position. Once the cam lock setscrew is in the locked position, the bone screw is inhibited from backing out of the bone screw bore. When the cam lock setscrew is in the unlocked position, a flat of the cam lock setscrew is adjacent the bone screw tang so the bone screw may be removed.

Spine plate implant with cam lock bone screw retention

A plate and an installation tool are provided for preventing a spinal facet joint implant from expulsing from its implant location between a superior and an inferior vertebra. A k-wire is used in cooperation with the plate and installation tool to guide them to the desired location. The plate includes a central threaded bore situated between one or two superior bone screw or bone connection barb bores and one or two inferior bone screw or bone connection barb bores. The installation tool includes a threaded plug at one end for receipt by the plate's central threaded bore for releasably holding the plate during installation. The installation tool has a superior structure and an inferior structure that can be a cannula or tang depending on the plate's form.

Facet plate for implant expulsion prevention

A lateral spine implant has a lateral spine cage and an associated lateral spine plate with one or more folding vertebral attachment arms, each arm configured for attachment to vertebral bone. The ability of the one or more arms to fold allows the lateral spine plate to be inserted/implanted at a lower profile height than traditional lateral spine plates. The lateral spine plate is meant to be used at times of intended or unintended compromise of the anterior longitudinal ligament (ALL) to prevent interbody cage migration, but may be adapted for any lateral plating application. Once expanded, each attachment arm is configured to receive a bone screw for securing the attachment arm to a vertebra, the bone screw retained by rotating cam lock nuts of the attachment arm.

Spine implant with an expandable cage and expandable vertebral attachment plate providing uniform rate movement

A spine implant for use in spinal facet joint fixation or to connect distracted portions of a vertebral lamina in a laminoplasty through use or non-use of a spacer. One or two bone screw plates are angularly adjustable relative to a base plate for attachment by bone screws to vertebral bone. One form of the spine implant has a base plate, a first plate pivotally connected to the base plate for angular adjustment relative to the base plate and configured to hold one or two bone screws for attaching the first plate to first vertebral bone, and a second plate configured to hold two bone screws for attaching the second plate to second vertebral bone. The second plate may be pivotally connected to the body for angular adjustment of the second plate relative to the base plate or fixed to the base plate at a predetermined angle.

Spinal facet joint and laminoplasty implant

An implant and method for spinal facet joint stabilization uses a wedge and plate adapted to accept prongs of a surgical instrument for installing the implant into a posterior spinal facet joint. The wedge has an anterior end with a threaded bore. A notch in each lateral side of the plate aligns with a groove in each lateral side of the wedge. Each notch and groove pair receives a prong of the surgical instrument to hold the wedge and plate during implantation. A superior tube of the surgical instrument supports a superior rod having an end configured for installing a bone screw attaching the plate to the superior vertebra of the spinal facet joint. An inferior tube of the surgical instrument supports an inferior rod having an end configured to attach to the threaded bore of the wedge along with the plate during introduction of the implant into the spinal facet joint, and installing the set screw to attach the plate to the wedge.
