Low profile spinal tethering methods

摘要

Methods and devices for treating spinal deformities are provided. In one exemplary embodiment, a low-profile spinal anchoring device is provided for receiving a spinal fixation element, such as a tether, therethrough. The device generally includes a staple body that is adapted to seat a spinal fixation element, a fastening element for fixing the staple body to bone, and a locking assembly for coupling a spinal fixation element to the staple body. In one embodiment, the locking assembly includes a washer that is adapted to couple to the staple body such that the spinal fixation is disposed therebetween, and a locking nut that is adapted to engage the staple body to mate the washer to the staple body.

1. A method for correcting spinal deformities, comprising:
implanting a staple in bone; inserting a fastening element through the staple and into the bone; positioning a substantially flat elongate flexible tether between opposed arms formed on the staple; positioning a washer between the opposed arms of the staple such that the arms prevent rotation of the washer; and applying a locking element to the staple such that a longitudinal axis of the locking element is co-axial with a longitudinal axis of the fastening element, the locking element engaging the opposed arms formed on the staple causing the washer and the staple to engage and bend the tether along a tortuous pathway.
