Systems, methods, and apparatus are described herein for obtaining medical diagnostic measurements from implanted sensors. In various embodiments, an apparatus may include two or more clamps to be rigidly clamped to the spinal fusion rod at a distance from one another, and a strain-sensing system that is removably mountable to the two or more clamps to span the distance. The strain-sensing system may include one or more strain-sensing elements. In various embodiments, the two or more clamps may be configured to transfer strain detected in the spinal fusion rod to the one or more strain-sensing elements of the strain-sensing system.

Apparatus for sensing strain on a spinal fusion rod

The present invention provides a systemfor measuring and remotely monitoring strain in an elementhaving a strain sensora telemetry circuitfor transmitting strain data to a remote location, and a reader modulefor transmitting energy to the telemetry circuit and receiving said data.
