Abstract: A spine implant for a TLIF surgical procedure is configured to be guided into place during implantation in conjunction with a complementary insertion instrument. The cage of the implant is constrained to a limited range of rotation about a pivoting post carried by the cage. The insertion instrument is configured to hold the post while controllably rotating the cage relative to the post in order to angularly position the implant during implantation. Range of rotational motion is controlled by the configuration of an opening in and end of the cage and a groove in the pivot post. A retaining pin of the implant extends from the cage into the groove of the post to rotationally connect the cage to the post.

Abstract: A variable height intervertebral spine implant is adjustable in situ having first and second trapezoidal components oriented such that the short surfaces/sides of their parallel surfaces/sides are adjacent, forming a first wedge-shaped pocket between opposing first skew surfaces/sides of the first and second components on a first end, and a second wedge-shaped pocket between opposing second skew surfaces/sides of the first and second components on a second end. First and second lateral flanges of both the first and second components cooperate to connect the first and second components together, and to allow height adjustment between the first and second components. A first wedge situated in the first pocket and a second wedge situated in the second pocket are connected via a drive mechanism that effects concerted movement thereof whereby contraction increases implant height while expansion decreases implant height. The wedges ride against the skew sides of the components.

Abstract: An adjustable implant includes a body portion including a first end, a second end including a bull nose, and a sidewall extending from the first end to the second end, a hook coupled to the body portion, the hook including a first hook portion extending from the body portion in a first direction, and a second hook portion extending from the first hook portion in a second direction that is different from the first direction, a first wing coupled to the first end of the body portion, and a second wing coupled to the body portion such that the distance between the first wing and the second wing is adjustable by a user, wherein the first and second wings include inward facing surfaces configured to be positioned adjacent portions of bone of a patient.

Abstract: An adjustable spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume and/or cross sectional area in the spinal canal and/or neural foramen. The adjustable implant provides a spinal extension inhibitor. The implant includes elliptical or oval shaped adjustable member or spacer for positioning between and adjustably spacing apart the spinous processes.

Abstract: An interbody spine implant has a PEEK body/cage and removable front, the body with bone screw holes of a diameter smaller than a greatest diameter of an associated bone screw such that received bone screws cut into the PEEK thus locking the bone screws to the body. A major diameter of a bone screw increases towards the head of the screw to cause interference between the PEEK body and the screw. This aids in preventing the screw from backing out of the body. Bone screw holes are angled to project the bone screw from either the top or the bottom of the body for receipt in upper and lower vertebral bone. Preferably, but not necessarily, the direction of the bone screw bores are staggered from one lateral side to another lateral side of the body.

Abstract: A spinal implant for immobilizing the C1 vertebra with respect to the C2 vertebra of the spine provides controlled coupling between the C1 and C2 vertebrae, and includes a C1 component attachable to the C1 vertebra, two C2 components attachable to the C2 vertebra, and a transverse element. The C1 component has two wings each of which retains a rod holder that rotates and translates for capturing a C2 component rod. Each C2 component has a hook for connection with a side of the C2 vertebra lamina and a rod for attachment to one of the rod holders of the C1 component. Each C2 component receives and secures the transverse connector which holds position of the C2 components relative to one another. Each C2 component may include a plate configured for compression against the C2 vertebra spinous process, with each plate including spikes to aid in preventing construct migration.

Abstract: A medical instrument set and method of use for surgically treating bony aberrations of the calcaneus such as calcaneal compression fractures. The present medical instrument set allows surgical treatment of bony aberrations through a minimally invasive procedure that provides better outcomes than both a closed reduction and an open reduction procedure. The medical instrument set includes one or more of an access needle, drill, depth guide, cement plunger, and curette. The access needle is used to provide access to a desired calcaneal site and is characterized by a cannula and a removable trocar tip. The drill is used to bore into the calcaneus. The depth guide is used to visually indicate how far a medical instrument extends beyond and/or through the access needle cannula. The cement plunger is used to introduce bone cement into the desired calcaneal site. The curette is used to mechanically create a void at the desired calcaneal site.

Abstract: A spinal interbody implant has a bone screw retention mechanism that prohibits bone screws from backing out after the bone screws are installed. A bone screw retention plate is received in a plate retention area of the implant to provide a barrier that keeps the installed bone screws from backing out of their bone screw pocket. The bone screw retention mechanism consists of a retention plate and a configured plate retention area in a face of the implant body. Retention plate fasteners may be used to retain the configured plate. In one form, the bone screw retention mechanism consists of a retention plate, a configured plate retention area in a face of the implant body, and a retention plate bolt. In another form, the bone screw retention mechanism consists of a retention plate, a configured plate retention area in a face of the implant body, and a retention plate bolt.
