Abstract: A method of determining disc space geometry with the use of an expandable trial having endplate-mapping capabilities. An expandable trial is inserted into the disc space and its height is adjusted to obtain the desired decompression and spinal alignment (which is typically confirmed with the use of CT or Fluoroscopic imaging). The endplate dome/geometry dome is then determined by one of the following three methods: a) direct imaging through the trial, b) balloon moldings filled with flowable in-situ fluid (for example, silicon, polyurethane, or PMMA) from superior/inferior endplates or c) light-based imaging through superior & inferior balloons.

Each bone fixation device includes at least one securement location on the fixation body that can attach to a securement device, such that the securement device fixes or stabilizes the mandible and the maxilla with respect to each other.

Abstract: Minimally invasive methods and devices for introducing a spinal fixation element into a surgical site in a patient's spinal column are provided. In general, the method involves advancing a spinal fixation element in a first, lengthwise orientation along a pathway extending from a minimally invasive percutaneous incision to a spinal anchor site. As the spinal fixation element approaches the spinal anchor site, the fixation element can be manipulated to extend in a second orientation, which is preferably substantially transverse to the first orientation, to position the fixation element in relation to one or more spinal anchors.

Abstract: A bone cement comprising a first component and a second component, wherein contacting the first component and the second component produces a mixture which attains a high viscosity an initial period and the viscosity of the mixture remains relatively stable for a working time of at least 5 minutes after the initial setting period, and the mixture is suitable for in-vivo use.

Abstract: Expandable fixation assemblies, expandable cranial fixation assemblies, and expandable intervertebral implant assemblies are provided for securing structures to bone and for securing bones and/or bone segments with respect to each other. An expansion member can be moved through at least a portion of an expandable fixation body, thereby causing expansion of the expandable fixation body, such that bone engagement features of the expandable fixation body engage surrounding structure, such as bone.

Abstract: Methods, systems, and devices are provided for guiding surgical instruments using radio frequency (RF) technology. In general, the methods, systems, and devices can allow a trajectory, e.g., an angular approach, of a surgical instrument relative to a patient to be identified during use of the instrument in a surgical procedure being performed on the patient. The trajectory can be identified using a plurality of RF modules. The methods, systems, and devices can allow the trajectory to be compared to a predetermined trajectory so as to identify whether the trajectory matches the predetermined trajectory. A result of the matching can be communicated to a user of the instrument. Based on the result, the user can maintain the trajectory, e.g., if the trajectory matches the predetermined trajectory, or can adjust the trajectory to closer align the trajectory with the predetermined trajectory, e.g., if the trajectory does not match the predetermined trajectory.
