Spine distraction implant and method

摘要

A method of inserting an interspinous-process implant includes using an insertion tool. The insertion tool includes an inner shaft disposed at least partially within an outer shaft. The inner shaft is longitudinally displaceable relative to the outer shaft and rotatably engagable with the implant. The implant is alignable with a first engagement portion on the tool, advantageously when a second engagement portion associated with the inner shaft is retracted.
