Abstract: An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.

The cutting guides include one or more stabilization members extending outwardly from the base portion and having a contact surface shaped to substantially match an outer surface of a portion of a scapula of the patient. The stabilization members are oriented to take into account the patient's anatomy in orienting and stabilizing the guide with respect to the glenoid. The guide hole of the base portion is for guiding the surgical instrument to create a guide hole in the glenoid.

Abstract: A system and method for use when forming an osteotomy that rely upon an arrangement of surgical instruments with a targeting guide having a handle extending substantially along a longitudinal axis, with one or more burr holes extending from a first side of the handle to a second side of the handle. A head is coupled to a distal end of the longitudinal handle. The head defines a plurality of guide holes sized and configured to receive a k-wire therethrough. The arrangement allows accurate adjustment of the surgical instruments in relation to the bones targeted for the osteotomy.

Abstract: A trocar assembly includes a head; an elongated tubular structure, having an open proximal end and an open distal end; a stationary cutting component, incorporating a large cutter having two sharp side-blades and a centrally disposed non-cutting soft tip that extends through the open distal end of the tubular structure; and a protection assembly, actuated via a compression spring, comprising a moveable cutter safety casing that extends through the open distal end of the tubular structure to cover the stationary cutting component and retracts from the open distal end to reveal the stationary cutting component. As proximally exerted pressure is applied to the cutter safety casing, a large incision is made in the fascia and the abdominal wall is penetrated, whereby the counter-pressure from the abdominal wall is released and a body cavity is reached safely.
