An expandable fusion device may include a first endplate and a second endplate. The expandable fusion device may also include first and second ramps configured to mate with both the first and second endplates. An inserter instrument includes an outer shaft having a bore extending longitudinally therethrough and an inner shaft extending through the bore in the outer shaft. The outer shaft is configured to engage the first or second opening in the second ramp, and the inner shaft is configured to engage the corresponding first or second opening in the first ramp to control implant height and/or lordotic angle.

A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In an exemplary embodiment, the present invention provides an intervertebral implant. The intervertebral implant may be configured to transition from a collapsed configuration having a first height and a first width to an expanded configuration having a second height and a second width.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.

An orthopaedic surgical instrument system includes a first broach including a first end configured to be separately secured to a handle and a tapered body having a plurality of cutting teeth defined therein, and a second broach including a first end configured to be separately secured to the handle in place of the first broach, a first tapered body extending distally from a second end positioned opposite the first end, and a second tapered body extending distally from the first tapered body. The tapered body of the first broach and the first tapered body of the second broach have a first outer geometry and the second tapered body has a second outer geometry different from the first outer geometry.

An elongate inserter has a distal end releasably connected to an expandable device for expanding body tissue and a proximal end including a trigger actuator. The expandable device comprises a superior endplate and an inferior endplate that are movable in an expansion direction relative to each other between opposing tissue surfaces of a body. The inserter includes a lifting platform comprising ramp surfaces that upon operation of the trigger actuator cooperatively engage complementary surfaces of expansion structure within the device to cause the superior and inferior endplates to move relatively away from each other. A driver is supported by the inserter for pushing an insert between the superior and inferior endplates after expansion of the device.

A spinal implant includes a first member having a wall that defines an axial cavity. A second member extends between a first end and a second end and defines a longitudinal axis. The second member is configured for disposal with the axial cavity and translation relative to the first member. A third member has an outer surface engageable with tissue and an inner surface disposed to dynamically engage the first end in response to the engagement of the outer surface with the tissue. Systems and methods are disclosed.

A prosthetic device for replacing at least part of one vertebral body, the prosthetic device being expandable from a fully collapsed state to a fully expanded state and comprising an upper endplate, a lower endplate and an expandable support structure extending between the two endplates, said expandable support structure being configured to displace the two endplates relative to one another along a longitudinal axis of the prosthetic device and to hold the two endplates at a minimum axial distance that corresponds to the height of at least one intervertebral disc and half a vertebral body, wherein the expandable support structure includes an anterior post and a posterior post, wherein the length (L1/L2) of each post is individually adjustable and is lockable independently from one another to hold the two endplates with an inclination of 0 to 40 relative to each other.

Systems and methods for treating musculoskeletal disorders of the spinopelvic anatomy including treating spinal deformities by spinopelvic fixation including fusion of the sacroiliac joint at the base of long spinal fusion construct cases. The system may include implants designed to be used as an adjunct to long spinal fusions to further the immobilization and stabilization of the sacroiliac joint. The implants may be designed to augment an S2AI screw and an S1 screw in order to improve durability of the foundation of the spinal construct. The implants may have a triangular cross section.
