A bone graft system for providing bone graft material to a site of interest includes a multiple unit bone graft material loading device and a conduit. The multiple unit bone graft material loading device may be configured to accept a plurality of pre-formed bone graft material units and includes a plurality chambers configured to accept a pre-formed bone graft unit. The conduit may include a first opening and second opening. The first opening may be operably connected with the multiple unit bone graft material loading device to accept bone graft material from the multiple unit bone graft material loading device. The second opening may be configured to deliver bone graft material to a site of interest.

Methods and systems for interbody implant and bone graft delivery

A retractor system includes a frame and first and second retractor blades. The frame includes first and second securement features. At least one of the first and second securement features is movable with respect to the frame when the at least one of the first and second securement features is mounted to the frame. The first and second retractor blades each have a distal portion and a proximal portion. The proximal portions of the first and second retractor blades are configured to be secured proximate to the first and second securement features respectively, such that the first and second retractor blades may be positioned in a first position wherein the first and second retractor blades are laterally opposed. A movement of the at least one securement feature that is movable with respect to the frame adjusts the angle of at least one of the retractor blades, wherein the at least one of the retractor blades may be adjusted between a first angle less than 90 degrees to horizontal and second angle greater than 90 degrees to horizontal.

Posterior lumbar retractor system

A retractor system includes a frame and first and second retractor blades. The frame includes first and second securement features. At least one of the first and second securement features is movable with respect to the frame when the first and second securement features is mounted to the frame. Proximal portions of the first and second refractor blades are secured proximate the first and second securement features respectively. In a first position the first and second refractor blades are laterally opposed. Movement of the securement feature adjusts the angle of at least one of the retractor blades so that at least one of the retractor blades may be adjusted between an acute angle and an obtuse angle to horizontal.

A spacer for implantation between adjacent vertebrae is provided. The spacer includes a distal end and a proximal end. The spacer also includes top and bottom surfaces spaced by sides. The top and bottom surface define a height, and the sides define a width. Each of the sides of the spacer may include a depressed region sunk into the side including a sloped surface at least toward the proximal end of the spacer. The distance between the sloped surfaces of the sides may decrease proximally to form a web having a leading edge proximate to the proximal end of the spacer. The web may be sized and configured to aid distribution of bone graft material to either side of the spacer, wherein bone graft material is supplied to a site of interest is distributed to at least one side of the spacer.

A bone collection system includes a plunger, a tube, and a manifold. The plunger has a bore therethrough, an insertion portion, and an inlet that accepts material being harvested from a patient. The insertion portion includes a filter to prevent passage of bone fragments. The tube accepts the insertion portion, defining a first and a second chamber of the tube. The filter separates the first and second chambers of the tube. The manifold is accepted by the tube, and has an outlet accepted by a suction source. The inlet of the plunger is in fluid communication with the first chamber, the first and second chambers are in fluid communication through the filter, and the second chamber is in fluid communication with the outlet. Material being harvested is drawn through the bone collection system, and bone fragments of the desired size collected in the first chamber.
