The present technology provides patient-specific implants. The implants can include a plate having a geometry contoured to mate with an identified anatomical structure at a target position. The plate can include a first projection having a first contact surface with a first topography designed to mate with a corresponding first surface of a first vertebral body, and a second projection having a second contact surface with second topography designed to mate with a corresponding second surface of a second vertebral body. The first topography can be different than the second topography. In some embodiments, the first and/or second projection can be configured to contact, and have topographies designed to mate, with a plurality of surfaces, such as two adjacent surfaces, of the respective first and second vertebral bodies.

Methods for securing a intervertebral cage to one or more levels of the spine with fixation. The fixation, which is typically a staple, is intended to be driven perpendicular to the proximal face of the cage and in-line with the inserter. After the cage is placed and positioned according to surgeon preference, a single piece fixation clip is then deployed and fixed in a manner that produces a zero-profile device.

An in-situ additive-manufacturing system for growing an implant in-situ for a patient. The system has a multi-nozzle dispensing subsystem and a distal control arm. The multi-nozzle dispensing subsystem in one embodiment includes first and second dispensing nozzles. The first and second nozzles include first and second printing-material delivery channels, respectively. In another embodiment, the in-situ additive-manufacturing system includes a multi-material subsystem having a dispensing nozzle including first and second printing material delivery channels. Controlling computing and robotics componentry are provided. In various aspects, respective storage for first and second printing materials, and one or more pumping structures, are provided.

The present disclosure provides for spinal implants configured for lateral insertion techniques deployable between a contracted position and an expanded position. The spinal implant may include a first endplate and a second endplate, each having a plurality of guide walls and inclined ramps. The spinal implant may further include a moving mechanism having first and second trolleys configured to act against the first and second plurality of ramps. The moving mechanism may further include a first set screw and a second set screw opposite the first set screw. The moving mechanism may be configured to operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws along a rotation axis, and may also operably adjust an angle of inclination between the first and second endplates upon rotating the first set screw or second set screw along the rotation axis.

An expandable interbody spacer that is delivered in the anterior approach with adjustable height and end plate angulation (lordosis). The expandable interbody spacer is configured to have an initial collapsed state having a first height suitable for being inserted into an intervertebral space defined by a pair of adjacent vertebrae, and an expanded state having a second height that is greater than the first height. The expandable interbody spacer may be expanded from the initial collapsed state to the expanded state in-situ. The expanded state increases the distance between the adjacent vertebrae and provides support to the adjacent vertebrae while bone fusion occurs and also provides rigid support between the adjacent vertebrae that withstands compressive forces. By inserting the expandable interbody spacer into the intervertebral space in the initial collapsed state, it is possible to perform the surgery percutaneously with minimal disruption to tissues surrounding the surgical site and intervening soft tissue structures.

The present disclosure describes an intervertebral disk replacement system. The system can include a tissue-engineered intervertebral disc that is combined with a bioresorbable stabilization system for structural guidance. The system can prevent or reduce intervertebral disk implant displacement and can increase the stiffness when compared to the implantation of the intervertebral disk implant without the stabilization system.

The present disclosure includes implant systems, devices, and implants. The interbody spacers including a first endplate, a second endplate, and a coupling member coupled to and extending between the first endplate and the second endplate. Methods of using the interbody spacers are also disclosed.

The present disclosure comprises a ball head, a neck part, a cover body, and a fastener, wherein the cover body is in a shape of a thin-walled cup, including a cup buckled and embedded on the femoral neck left after the femoral head is removed and a circle of skirt plates attached to the lower edge of the cup to extend the covering range of the cup to the femoral neck and the intertrochanteric femur; a through hole for a cable to penetrating through is formed in the tail end of each skirt plate, and a limiting clip for limiting the cable for cerclage of the cup is arranged outside the skirt plate; and then stable rigid connection is conducted using a compression ring; and the fastener comprises a screw or an additional perforated steel plate and a cable which is fixed in a cerclage and tension manner.

A mesh implant and/or container may be used as an intervertebral implant. The mesh implant may be anchored or otherwise fixed to the vertebral endplates to prevent the implant from migrating forward and out anteriorly to the spinal column. The mesh implant may be knitted with a rip stop, elastic or other stich pattern to prevent unraveling or tearing.
