摘要：
One or more techniques and/or systems are disclosed for a system for noninvasive adjusting fastener tensioning has an elongated shaft having a slot defined therein. The shaft has a first end oppositely disposed from the second end. An associated rod or rods may pass through each end. Selectively adjustable fasteners may have a plurality of magnets disposed in the head of the fastener. An external drive device generating a magnetic field may be used to rotate the fasteners via the magnets in the fastener head externally without the need for surgery. The fasteners may move in and out from the shaft and contact the rod to adjust tensioning.
