A bone graft delivery system and method for using same to deliver graft material into a surgical site. The method includes the steps of providing a hollow tube configured to receive the graft material, releasably attaching an implant to a distal end of the hollow tube so as to communicate with at least one opening in the distal end of the hollow tube, the implant being configured to receive the graft material delivered through the hollow tube; placing the implant within the surgical site; advancing the graft material through the hollow tube; conveying graft material through the hollow tube into an interior of the implant, whereby the implant is at least substantially filled with the graft material; and discharging the graft material through at least one opening in the implant into the surgical site, whereby the surgical site is at least substantially filled with the graft material.

Devices and methods of correcting vertebral misalignment, including, e.g., spondylolisthesis, are disclosed. In one embodiment, a vertebral implant may include an assembly configured to be secured to a first vertebral body, wherein the assembly includes a frame made of a first material and at least one end plate made of a second material different than the first material; a reducing plate configured to be slidably received over the central portion, wherein the reducing plate is configured to be secured to a second vertebral body; and an actuator configured to move the reducing plate relative to the frame.

An intervertebral implant for being implanted between adjacent vertebrae is provided. The implant includes a generally elongate implant body having a length extending between opposite longitudinal ends thereof, a superior face and an inferior face. The superior face and inferior face include cortical teeth adjacent to the implant body longitudinal ends. Additionally, the superior and inferior faces include longitudinally central teeth intermediate the cortical teeth and have bone engaging ends. The central teeth have a sharper configuration than that of the cortical teeth bone engaging ends for biting into the softer central bone material of the vertebrae. The cortical teeth are arranged in a first density per unit area and the central teeth are arranged in a second density per unit area that is less than the first density.

Intervertebral implant systems include spacers that may have solid and porous bodies integrally formed together as a single part. The bone-facing sides of the spacers include asymmetric lobes which may include solid and/or porous portions. Bone anchor holes may extend through the spacers and lobes, to receive bone anchors. A helically fluted bone anchor may be received in the bone anchor holes.

An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.

An improved method of fusing the sacroiliac joint and tools for accomplishing the same is disclosed. In one embodiment, the present invention is a method that uses an intra-articular joint fusion device for connecting the sacrum and ilium that includes creating a first incision in the patient's skin proximal to the patient's sacroiliac joint, inserting a surgical channel tool into the incision from the patient's posterior, creating a void in the sacroiliac joint, inserting a fusion implant into the void, the fusion implant having at least one fixation element for engagement with bone tissue in the articular surfaces of the sacrum and the ilium, and driving the fusion implant into the void such that the at least one fixation element engages with bone tissue in an articular surface of at least one of the sacrum and ilium, and the fusion implant fixes relative positions of the sacrum and ilium.

A system includes a first prosthesis. The first prosthesis may include a body extending along a length from a first side to a second and including a third side disposed between the first side and the second side. The body may include a pair of spaced apart rails between which a channel is defined. A stem and a first fixation element may extend upwardly from the third side. A method may include coupling the first prosthesis to bone.

Various systems and methods are disclosed for joining multiple components of a prosthesis. For example, a system includes a first component having a body extending from a first end to a second end. Each of the first and second ends including a coupling element. At least one end including a male coupling element including a detent disposed within a hole defined by a protrusion, the detent being biased by a biasing member. A method includes coupling a first component to a second component. Coupling the first component to the second component includes aligning a female engagement element provided by the first component with a male coupling component provided by the second component and inserting the male coupling element into the female coupling element.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

Various surgical tools having a movable handle mechanism including a positioning handle are disclosed. The movable handle mechanism may be configured to move forward and backward in a longitudinal direction along the housing and rotate clockwise and counterclockwise around the housing. In various embodiments, the housing may include a plurality of channels and each channel may have at least one detent. The movable handle mechanism may be configured to securely couple to the housing via one channel of the plurality of channels and one detent of the plurality of detents. At least one surgical tool may include a drill having an angled tip portion and a sleeve configured to protect adjacent structures from lateral edges of the drill bit when the drill bit is rotating. Another surgical tool may include a screwdriver having an elastic retaining clip configured to progressively release a bone screw therein at an extraction force.
