Abstract: In one aspect, the present disclosure provides a monolithic percutaneous-screw system for use in spinal surgery. The system includes (i) a receiver having a distal base and a pair of opposing arms extending proximally from the base, a pair of opposing distal breakoff sections, each connected monolithically to a proximal end of a corresponding one of the arms, (ii) a pair of opposing proximal breakoff sections, (iii) a pair of opposing intermediate extenders, each extending from a distal end, connected monolithically to a corresponding one of the distal breakoff sections, to a proximal end connected monolithically to a corresponding one of the proximal breakoff section, and (iv) a guide cap connected monolithically to both of the proximal breakoff sections.

Abstract: A surgical instrument comprises a first member including a drive engageable with a first mating surface of a bone fastener. A second member is rotatable relative to the first member and includes an element engageable with a second mating surface of the bone fastener. An actuator is connected with the second member and includes visual indicia of engagement of the element with the second mating surface. Systems, spinal implants and methods are disclosed.

Abstract: A surgical guide comprising a body including an inner surface that defines a cavity configured for disposal of a surgical instrument. The body further defining an opening communicating with the cavity. A connector disposable with the opening and engageable with a surgical robot. A release is engageable with the connector. Systems, spinal constructs, implants and surgical instruments are disclosed.

Abstract: A surgical instrument comprises an outer sleeve including an inner surface that defines a cavity. An inner shaft is fixed with the outer sleeve and extending within the cavity. The inner shaft includes a drive engageable with a first mating surface of a bone fastener. An inner sleeve is disposed between the inner shaft and the outer sleeve. The inner sleeve is rotatable relative to the outer sleeve and includes an element connectable with a second mating surface of the bone fastener. Systems, spinal implants and methods are disclosed.

Abstract: A spinal implant comprises a proximal member including a body having a first diameter and a head having a second diameter. The body includes an outer surface disposed for non-fixation with a superior facet of a vertebra, and the second diameter being greater than the first diameter. The spinal implant comprises a distal member having a third diameter and being configured for fixation with an inferior facet of an adjacent vertebra. Systems, surgical instruments and methods are disclosed.

Abstract: A multiple-cap-remover for removing and holding spinal-implant guide caps, including a chamber component and a plunger movable disposed within the chamber. The chamber component has a chamber wall extending to an open end, and a cap-retaining component extending radially inward from an inner surface of the chamber at or adjacent the distal end. The distal opening is sized and shaped to allow the guide caps to pass through the opening and into the chamber component. The chamber component is sized and shaped to receive, one at a time, and hold simultaneously, multiple caps removed from respective spinal-implant assemblies using the instrument. The instrument may further have a sliding component connected movably to a body and connected to the plunger such that, when moved distally, it moves the plunger to push the caps captured beyond the cap-retaining component and out of the chamber component via the opening.
