Abstract: Systems and methods for estimating anatomic alignment between two or more bones are described herein. An example method can include registering an anatomic reference frame. Additionally, the method can include establishing a respective rotational relationship between each of one or more bones and an orientation sensor attached to each of the one or more bones. The method can also include receiving, from each of the orientation sensors, orientation information, and then calculating an orientation of a bone relative to the anatomic reference frame. The method can further include calculating, using the respective orientations of the bones relative to the anatomic reference frame, an anatomic alignment parameter between first and second bones.

Abstract: An orthopedic implant which generally includes a frame structure and a porous structure. Both the frame and porous structure at least partially define at least six surfaces which make a three-dimensional profile of the implant. The porous structure is positioned at least partially within the three-dimensional profile.

Abstract: A medical device and a method and process for at least partially forming a medical device, which medical device has improved physical properties.

Abstract: An example expandable interbody device can include a structural body having an upper endplate and a lower endplate, where the endplates are shaped to nest tightly in a closed position. The device can include at least one wedge block and at least one linkage block arranged between the upper and lower endplates of the structural body. The device can include a drive screw threaded through the at least one wedge block and the at least one linkage block. The drive screw can be configured to rotate and drive the at least one wedge block to expand the upper and lower endplates of the structural body from the closed position to an intermediate position. Additionally, the drive screw can be further configured to rotate and drive the at least one linkage block to expand the upper and lower endplates of the structural body from the intermediate position to an open position.

Abstract: An example augmented reality (AR) system can include a frame, a lens attached to the frame, and a plurality of cameras attached to the frame. The cameras can be configured to record a real-time image. Optionally, the real-time image can include a portion of a subject's body and/or one or more surgical instruments. Additionally, the AR system can include a plurality of inertial measurement units, where a respective inertial measurement unit is attached to each respective camera. Optionally, the AR system can be configured to display image data (e.g., medical image data) registered and superimposed on the real-time image as seen by the user of the AR system.

Abstract: A medical device and a method and process for at least partially forming a medical device, which medical device has improved physical properties. The one or more improved physical properties of the novel metal alloy can be achieved in the medical device without having to increase the bulk, volume and/or weight of the medical device.

Abstract: An example expandable interbody device can include a structural body having an upper endplate and a lower endplate. The device can include at least one wedge block and at least one linkage block arranged between the upper and lower endplates. The linkage block can include a plurality of linkages and a shear pin disposed at a respective proximal end of each of the linkages. The device can include a drive screw extending through the wedge and linkage blocks. The drive screw can be configured to rotate and drive the wedge block to expand the upper and lower endplates of the structural body from the closed position to an intermediate position. Additionally, the drive screw can be further configured to rotate and drive the linkage block to expand the upper and lower endplates of the structural body from the intermediate position to an open position.

Abstract: Various implementations include an anterior cervical fixation plate for fixating portions of a cervical spine to facilitate bone fusion. The plate includes a first portion, a second portion, and a bridge. A first surface of the first portion and a first surface of the second portion each define two fastener openings extending from the first surface of the first portion to a second surface of the first portion. The first side and the second side of the centrally located bridge each extend from the second side of the first portion to the first side of the second portion. The second side of the first portion, the first side of the second portion, and the first side of the bridge define a first window. The second side of the first portion, the first side of the second portion, and the second side of the bridge define a second window.
