Abstract: A method of treating a spine includes implanting at least a portion of a spinal construct in a patient. The method further includes attaching one or more smart implants to the spinal construct. Each of the one or more smart implants includes (a) an attachment portion configured to attach the smart implant to the spinal construct, and (b) at least one sensor configured to measure an aspect of the spinal construct when the smart implant is attached to the spinal construct. The method further includes receiving, from the one or more smart implants, sensor information related to the aspect of the spinal construct and performing at least one intra-operational adjustment to the spinal construct based on the received sensor information.

Abstract: A spinal implant includes an attachment portion having an opening configured to capture a longitudinal member therein, wherein the attachment portion is the only attachment means of the spinal implant. The spinal implant further includes a housing integrally connected to the attachment portion and defining a sealed cavity for supporting a microelectronics assembly and a power source therein. The spinal implant further includes at least one antenna in electrical communication with the microelectronics assembly and at least one sensor in electrical communication with the microelectronics assembly, wherein the microelectronics assembly is configured to transmit information received from the at least one sensor to an external device using the at least one antenna.

Abstract: A template device is used layout and marking geometric shapes such as martial arts or other sports rings on a floor. The device includes a central body at or near the center, and an extension reaching from preferably at least three sides of the central body to the perimeter, of the geometric shape. Both central body and extension are rigid or substantially rigid, maintaining the shape of the template device, including optional wire/cable around or along the extension, during both use on the floor and transport to adjacent floor areas. The template device covers a very small percentage of the geometric shape area, by means of empty space in the extension or between members of the extension. The resulting light-weight and small-volume device is easy to move and break down into a small package. The extension may include radially-extending legs attaching at their outer ends to the wire/cable perimeter.
