SPINAL SURGERY INSTRUMENTS, SYSTEMS, AND METHODS
An insertion assembly may include a flexible tool and a DTS guide configured to engage an intervertebral spacer having a fastener channel oriented at a first angle. The DTS guide may include a DTS guide channel oriented at the first angle which may be aligned with the fastener channel. The flexible tool may include a flexible shaft and a working member disposed at a distal end of the flexible shaft. The working member may be received through the DTS guide channel at the first angle. At least a portion of the flexible shaft adjacent the DTS guide member may flex while the working member is received through the DTS guide channel, such that a distal portion of the flexible shaft may be at a greater absolute angle relative to a DTS guide shaft than a proximal portion of the flexible shaft.
INTERBODY FUSION DEVICE COMPRISING TEXTURED SURFACES
An expandable interbody fusion device and an associated instrument for inserting the device into an intervertebral disc space, expanding the device and for use in delivering graft material into the device once expanded in the disc space. The device is small enough to fit through Kambin's triangle yet is capable of expanding both in the vertical direction to accommodate spinal lordosis and in the lateral direction to provide sufficient structural support for opposing vertebral bodies laterally within the disc space. A process of forming textured top and bottom surfaces of the device by initially laser ablating each surface with a nano-second pulsed laser followed by laser ablating those surfaces with a femto-second pulsed laser.
Systems for Sacroiliac (SI) Joint Stabilization
Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide having a bone dislodging member adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint, and a bone harvesting assembly adapted to extract and collect dislodge bone material from the bone dislodging member after creation of the pilot SI joint opening.
Implant delivery system
A delivery device includes a guide tool and an impact tool. The guide tool includes an elongate body formed with a longitudinal guide channel, whose inner perimeter is made to complement an outer contour of an implant. The elongate body is formed with a longitudinal impact-tool channel, whose inner perimeter is made to complement an outer contour of the impact tool.
Method for fusing a human or animal joint as well as fusion device and tool set for carrying out the method
The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.
IMPLANTABLE VERTEBRAL FRAME SYSTEMS AND RELATED METHODS FOR SPINAL REPAIR
A system for performing surgical repair of the spine includes a distractor and a permanently implanted bone plate system. A surgical repair methodology is also disclosed that employs an implanted bone plate system with a substantially void internal volume which is attached to adjacent vertebrae subsequent to the distraction and adjustment of curvature of the vertebrae and prior to the excision of disc and/or end plate tissue through the bone plate. The device further facilitates the subsequent delivery of an interbody repair device for the purpose of either fusion or dynamic stabilization, such as by disc arthroplasty. The plate may be permanently implanted, such as when a fusion between the attached vertebral bodies is desired, but it need not be permanently implanted.

Sacroiliac joint stabilization prostheses
Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have an integral structure with opposed elongated sections connected by a bridge section. The elongated sections, in some instances, have an unequal length.
STABILIZED TOTAL ANKLE PROSTHESIS
The present invention relates to a stabilized ankle prosthesis configured for use in patients with compromised soft tissue in the ankle. The prosthesis of the present invention is a two-component design comprising a stabilizing lip configured to constrain movement in the general direction of compromised soft tissue.
Hip stem prosthesis
A hip stem prosthesis is provided for treating a deficient hip joint.
