Bone grafting and compaction
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.
Intervertebral disc prosthesis and method
The present disclosure generally relates to an intervertebral disc prosthesis for partially or totally replacing an organic intervertebral disc. The disc prosthesis includes an interbody device, a face plate and a pair of locking mechanisms for achieving dual fixation in the cephalad and caudal direction. Methods according to the present disclosure achieve such dual fixation in a single fixation step.
EXPANDABLE INTERSPINOUS PROCESS FIXATION DEVICE
An expandable interspinous process fixation system capable of restoring spinal stability and facilitating fusion. In one embodiment, the expandable interspinous process fixation system 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. Each endplate supporting fixed and/or adjustable spinous process engaging plates.
Adjustable implant and insertion tool
An adjustable spinal implant includes a lower body, an upper body, a locking pawl, and a locking key. The upper body and the lower body are pivotable relative to one another between a collapsed position and an expanded position. The upper body includes a locking flange that extends towards the lower body. The locking pawl is coupled to the lower body and is moveable between a locked position such that the upper and lower bodies are fixed relative to the one another and an unlocked position such that the upper and lower bodies are moveable relative to one another. The locking key is moveable between a locked state such that the locking pawl is fixed in the locked position and an unlocked state wherein the locking pawl is moveable between the locked position and the unlocked position.
System and method for implanting a secondary glenoid prosthesis
A method of implanting a shoulder prosthesis in a scapula of a patient includes the step of placing a guide over a primary glenoid component previously implanted within the scapula of the patient. The method further includes the steps of removing the primary glenoid component from the scapula and preparing the scapula for implantation of a secondary glenoid component, wherein the removing and preparing steps occur simultaneously.
Lockable Spinal Implant
A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.
Oblique expanding fusion cage device and method
An oblique expanding fusion cage device including a body with a superior portion and an inferior portion. The superior portion and the inferior portion have a proximal end and a distal end. The fusion cage device also includes a pathway, an opening, and an expanding member. The pathway travels from the proximal end to the distal end of the device between the superior and inferior portions. The opening in the proximal end of the body enables access to the pathway. The expanding member may be re movably inserted into the opening and is moveable toward the distal end of the body, wherein the expanding member engages the superior portion and the inferior portion as the expanding member moves distally within the pathway.
Detachable knee trial
A knee trial which is coupled to identify the mobility of an implant before the implant is implanted by total knee arthroplasty, and more particularly, a detachable knee trial which includes a plate trial, an insert trial, and an adapter for easy attachment and detachment of the two trials, wherein the adapter includes an elastic member on one side thereof to firmly couple the two trials by pressing the plate trial and the insert trial with opposite ends of the elastic member and to alleviate the burdens of an operator and a patient by allowing the adapter to be attached and detached even only with a simple operation of pressing the adapter and compressing the elastic member by a hand and promptly and precisely performing an operation of selecting an implant of a suitable size while applying various trials in the total knee arthroplasty process and shortening surgery time, alleviating the burdens of a surgeon and a patient, and wherein one side of the adapter is formed of plastic, making it possible to couple the plate trial and the plate implant without leaving a flaw and the like in the plate trial and the plate implant.
SACROPELVIC FUSION IMPLANT SYSTEM FOR PROVIDING A FOUNDATION FOR SPINOPELVIC FIXATION CONSTRUCTS IN ADULT SPINAL DEFORMITY SURGERY
A method of surgically treating a patient suffering from severe pain and disability of the low back and buttock by stabilizing the patient's spinal column to their pelvis with an implant system including surgical tools and an implant designed to prevent movement between the sacrum and the ilium while being able to attach to a spinal fusion rod which connect to pedicle screws implanted in the bones of the spine of the patient in order to offer lasting relief of the patient's symptoms. The system is designed to address complications in adult spinal deformity by optimizing spinopelvic fixation via-a-vis the unique biomechanics of the SI joint. The sacropelvic system is a surgical solution which provides an additively manufactured implant at the base of the spine employing an S2AI trajectory while utilizing assisting technologies including surgical navigation and intraoperative neurophysiological monitoring.
EXPANDABLE FUSION DEVICE AND METHOD OF INSTALLATION THEREOF
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. The intervertebral implant may be configured to transition from a collapsed configuration having a first width and a first height to an expanded configuration having a second width and a second height.
