Abstract
A system for inserting an anchor member into bone includes a receiving member and an anchor member receivable within the receiving member. The receiving member is elongate along a longitudinal axis and has a proximal end and a distal end spaced from the proximal end along the longitudinal axis. The receiving member has an internal surface that defines a transmission element. The anchor member includes an engagement element configured to rotatably engage the transmission element such that the transmission element is configured to drive the anchor member in a distal direction relative to the transmission element so as to rotatably decouple the engagement element from the transmission element. The distal direction extends from the proximal end to the distal end of the receiving member and is parallel with the longitudinal axis.
