The FAI resurfacing controller may include an osteophyte identifier to set a virtual 3D boundary surface between native bone surface and the at least one osteophyte. The FAI resurfacing controller may include a resurfacing navigator to generate and output a navigation file. The navigation file may include the model with the 3D boundary surface between native bone surface and the at least one osteophyte.

Abstract: A retractor system used in preparation for an oblique lateral interbody fusion surgical procedure includes a first retractor blade having a first proximal portion and a first distal end; a second retractor blade having a second proximal portion and a second distal end; and a connecting device that is configured to connect the first retractor blade to the second retractor blade. The first distal end of the first retractor blade is configured to engage a posterior portion of the vertebra and the second distal end of the second retractor blade is configured to engage an anterior portion of the vertebra. The length of the first retractor blade is less than approximately 96 percent of the length of the second retractor blade, and the first distal end of the first retractor blade extends at a non-zero angle from the first proximal portion of the first retractor blade.

Abstract: A dynamic disc assembly has a superior end plate, an inferior end plate, and a core. The core has surfaces of an annular Fresnel shape and a linear Fresnel-like shape combined to control the dynamic range of motion (ROM) movement arranged to match anatomical ROM. The core is interposed between and held against interior surfaces of the superior end plate and the inferior end plate. The assembly further has a pair of coupling cords, one coupling cord at each lateral end of the superior and inferior end plates wherein each lateral end of each end plate has one or more cord connections attached and affixed to the coupling cord to form and retain the dynamic disc assembly.

The system may include a computing system communicatively coupled to the mesh of cameras, the computing system including a processor and a memory device. The computing system may be used to generate tracking data for a tracked object from images or image data taken by one or more cameras of the mesh of cameras.

Abstract: Retractor blades for a retractor system are disclosed. The blades are designed for use in preparing an area of the body for a surgical procedure.

Abstract: A retractor system for use in preparing an area of the body for a surgical procedure is disclosed. The retractor system includes retractor blades that can be independently inserted and positioned within the body. The system also includes articulating arms that can be used to secure the retractor blades to one another and to rigidly fix the retractor blades in place relative to an operating table or other fixed structure.

Abstract: A system and method of positioning a spinal implant into an intervertebral space comprises the steps of: cutting an incision through the skin toward an intervertebral space between a L5 and S1 vertebra; inserting an uncoupled first, second and third retractor blade into the incision to pre-position the retractor blades prior to retraction; coupling the pre-positioned first retractor blade to a connector arm to connect the first retractor blade to a table arm; attaching a blade to blade connector and mini flex arm to couple the second blade to either the first blade or third blade; and wherein the three uncoupled blades, once pre-positioned and then coupled, the blades are retracted to open the incision and expose the vertebral bodies.

Abstract: Systems and methods for training and using machine learning models to classify vehicles from highway radar systems are provided. The training systems may use auxiliary radar processing to separate events by lane, length, and/or speed, and then use separate event data groups pooled from similar or proximate lanes, lengths, and/or speeds to train multiple models. At estimation time, incoming events may be grouped using similar groupings as those used during training to select which model to use. An incoming event may be applied to the neural network operations of the selected model to generate an estimate. Generating an estimate may involve successive applications of multiple linear convolutions and other steps along varying or alternating dimensions of the in-process data.
