A bone screw has a first portion including a head. A second portion includes a threaded shaft having a length and a major diameter. The shaft includes a length-to-major diameter ratio of less than about 2.0. The thread has a minor diameter and includes a major-diameter-to-minor diameter ratio of greater than about 2.0. The shaft further has at least one thread including a pitch of greater than about 1.0 mm and defining a pitch cavity for disposal of tissue. Systems and methods of use are disclosed.

Surgical implant and method of use

A driving instrument for adjusting a spinal implant includes an outer shaft having a distal end configured to actuate a proximal adjustment assembly of a spinal implant, and an inner shaft having a distal end configured to actuate a distal adjustment assembly of the spinal implant. The inner shaft is disposed within the outer shaft, with a proximal end of the inner shaft extending proximally from the outer shaft. The proximal end is configured to be rotated such that rotation of the inner shaft results in simultaneous rotation of the inner and outer shafts, with rotation of the outer shaft ceasing at a first value of resistance associated with the proximal adjustment assembly and rotation of the inner shaft ceasing at a second value of resistance associated with the distal adjustment assembly such that cessation of rotation of the inner shaft is independent from cessation of rotation of the outer shaft.

Devices for inserting and expanding spinal implants

A surgical instrument includes a first arm having a slot and a part defining a cavity configured for disposal of a spinal implant. The part is sagittally movable relative to vertebrae and selectively fixable relative to the first arm. A second arm includes a slot and a part defining a cavity configured for disposal of the spinal implant. The part of the second arm is sagittally movable relative to the vertebrae and selectively fixable relative to the second arm. The first arm has a member that is movable within the slot of the second arm and the second arm has a member that is movable within the slot of the first arm to facilitate movement of a first vertebral surface relative to a second vertebral surface. Systems, spinal constructs, implants and methods are disclosed.
