US Patent 11911282 Spinal implant system and method

A spinal implant includes an outer body extending along an axis between opposite first and second ends. The outer body defines a bore and a first thread. An inner shaft includes opposite first and second ends. The second end of the inner shaft is positioned in the bore. The inner shaft includes a second thread that mates with the first thread. The second thread includes a series of gear teeth. An end plate is coupled to the first end of the inner shaft. A driver includes a gear configured to engage the gear teeth such that rotation of the driver relative to the outer body rotates the inner shaft relative to the outer body to translate the inner shaft relative to the outer body along the longitudinal axis. Systems and methods are disclosed.
