  • Patent number: 9788867
    Abstract: A method for treating vertebrae comprises the steps of: connecting at least one fastener with portions of vertebrae; providing a fastener comprising a first portion including a receiver defining an implant cavity and a member disposable with the implant cavity and movable relative to the receiver, and a second portion defining a longitudinal axis and being configured to penetrate vertebral tissue, wherein the receiver is non-pivotable relative to the longitudinal axis and connecting the fastener to the vertebrae; providing a longitudinal element; connecting a first portion of the longitudinal element with the at least one fastener; derotating the vertebrae to a selected orientation; and connecting a second portion of the longitudinal element with the fastener to substantially maintain the vertebrae in the selected orientation. Systems are disclosed.
