## Abstract

A system for assessing a status of a spinal implant includes a wearable apparatus having an electronics system and one or more spinal implants in communication with the wearable apparatus. The electronics system includes a first short-range receiver, a first short-range transmitter, and an inertial measurement unit. The wearable apparatus is configured to constrain one or more movements of a wearer when worn. The one or more spinal implants include one or more sensors configured to measure one or more characteristics of a fusion status of the spinal implant, a second short-range receiver, and a second short-range transmitter. The one or more spinal implants are configured to communicate one or more of the measured characteristics to the wearable apparatus via the second transmitter.
