Systems, devices, and methods suitable for use with procedures performed at least partially percutaneously are provided. In some procedures, two or more access devices for providing access to adjacent surgical locations within a patient are used. Certain embodiments of the access device comprise an elongate body having a distal end with one or more cutouts. The cutouts on adjacent access devices are generally aligned with each other to permit passage of a portion of a fixation element from one access device to the other access device. A fastener with an elongated removable head may be delivered to the surgical site through the access device. After a distal end of the fastener is secured to the surgical site, a portion of the elongated housing is detached from the remainder of the fastener and removed from the patient.

Methods and apparatus for access to and/or treatment of the spine

GPS hood

A surgical instrument extendable through a cannula for moving a first bone portion relative to a second bone portion includes a first portion having a longitudinal axis engageable with a first member connected with to the first bone portion. A second portion is engageable with a second member connected with the second bone portion. The second portion is movable relative to the first portion from a first position toward a second position to move the first and second bone portions away from each other. An actuator connected with the second portion moves the second portion relative to the first portion in a direction extending transverse to the longitudinal axis.

Surgical instrument for moving vertebrae

In one embodiment, an access device is inserted through an incision in skin of a patient. The access device is expanded from a first configuration to a second configuration, the second configuration having an enlarged cross-sectional area at a distal portion of said access device such that the distal portion extends across at least a portion of the interbody space. A prosthetic spinal disc implant is then delivered through the access device.
