Placement apparatus and methods of use for impanation of spacers within an inter-vertebral disc space. In one embodiment, the load-bearing superstructure of the implant is subdivided and the bone forming material is positioned within an internal space of the placement instrument but external to the load bearing elements themselves. At least a portion of the bone graft material is freely contained within the disc space. A method of using the device is also described. In one embodiment, the placement device is used to place the implantable spacers at opposing ends of the disc space using a directly lateral surgical approach.

A selectively expanding spine cage has a minimized cross section in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

Provided is a total talar replacement prosthesis that has a metallic body shell and a metallic or biologic core, where the metallic body shell includes one or both of a removable calcaneus attachment and a removable navicular attachment. The attachments, when removed, exposes a respective calcaneus-facing surface or a navicular-facing surface that can enhance fusion to the respective bones, calcaneus and/or navicular.

This disclosure describes manufacturing of a device configured to guide bone and tissue regeneration for a bone defect. A method may include receiving a three-dimensional digital model or scan representing an anatomical feature to be repaired, generating a simulated membrane using the three-dimensional model, the simulated membrane being configured to cover the anatomical feature to be repaired, generating a digital two-dimensional flattened version of the simulated membrane, and generating code or instructions configured to cause a three-dimensional printer or milling device to produce a trimming guide that includes an opening corresponding to the flattened version of the simulated membrane and that further includes a cut-out configured to hold a premanufactured membrane. The trimming guide may be operative as a guide for marking or cutting the premanufactured membrane through the opening while the premanufactured membrane is held in the cut-out.

An interbody fusion cage having upper and lower canals for receiving the heads of bone screws that have been pre-installed in opposing vertebral body endplates. The proximal wall of the cage preferably has a vertical slot that communicates with each canal and is adapted to allow access by a screwdriver and tightening of the screws.

A rotator cuff balloon (10) is disclosed, the rotator cuff balloon (10) includes a limiting structure (100) and a protective structure (200) connected to the limiting structure (100). The limiting structure (100) defines a curvature along a coronal plane. The rotator cuff balloon (10) conforms to the physiological structure of the human shoulder joint limits itself in the subacromial space and can reduce a patient's foreign body sensation, dislocation, functional failure and other adverse events.

A spinal implant comprises a first member, a second member and an actuator defining a transverse pivot axis. A first link is connected to the first member and the actuator adjacent the pivot axis. The first link includes an inner surface defining a cavity. A second link is connected to the second member and the actuator adjacent the pivot axis. The actuator is rotatable for translating the pivot axis such that the second link is movable within the cavity to move the members between a contracted configuration and an expanded configuration. Systems and methods of use are disclosed.

An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

An implantable, autonomously growing medical device is disclosed. The device may have an outer, braided outer element that holds an inner core. Degradation and/or softening of the inner core permits the outer element to elongate, allowing the device to grow with surrounding tissue. The growth profile of the medical device can be controlled by altering the shape/material/cure conditions of the inner core, as well as the geometry of the out element.

The present disclosure provides a bone-implantable device and methods of use. The bone-implantable device comprises a body having an exterior surface, wherein a portion of the exterior surface includes a cured osteostimulative material comprising MgO.
