    Publication number: 20190247100
    Abstract: A system for securing a flexible member to a vertebra includes a flexible member, a fixation member, and an inserter. The flexible member includes two ends. The fixation member includes a head and a shank that defines a longitudinal axis of the fixation member. The head defines a slot that passes through the head orthogonal to the longitudinal axis. The slot receives a portion of the flexible member. The inserter includes a handle and a tubular member that has proximal and distal end portion. The proximal end portion is attached to the handle and the distal end portion extends from the handle. The tubular member defines a passage between the proximal and distal end portions. The distal end portion includes a couple for receiving the head of the fixation member with the portion of the flexible member received in the slot of the flexible member.
