A screw sheath is provided for advancing a pedicle screw from outside a patient to the vertebra during minimally invasive spinal surgery. The sheath includes an elongate tubular construct having an open proximal end, a tapered distal tip with an open end. The conical tip can be deformed or reconfigured when subject to the axial force of the pedicle screw being advanced into the pedicle or by manual operation of the operator. The pedicle screw is advanced through the sheath to the pedicle and retained by the tip of the sheath. Then a driver is used to advance the screw through the sheath and into the vertebra.
