Systems, devices and methods for vertebral fusion and SI joint stabilization.

Fusion cages and methods for sacro-iliac joint stabilization

Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac ('SAI') trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

Implants for spinal fixation and or fusion

A bone screw implant comprising a bone screw and a sleeve. The bone screw includes a first end, a second end opposite the first end, a cannula extending from the first end to the second end, an externally treaded portion provided between the first end and the second end, and at least one cutting flute. The at least one cutting flute extending from the first end toward the second end, where the cutting flute comprises at least one window extending through the cutting flute and in communication with the cannula. The sleeve comprising a cylindrical body portion extending about the second end of the bone screw, and a plurality of projections extending from the cylindrical body portion configured to engage bone as the bone screw is threadingly advanced.

Bone screw implant for sacroiliac joint fusion

The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing or stabilizing a plurality of bones is provided. The system includes an implant structure having stem portion and a head portion, the stem portion having a rectilinear cross sectional area. A tulip or saddle structure can be attached to the head portion, and a rod can be secured within the tulip or saddle structure.

Implants for spinal fixation or fusion

A bone screw for sacroiliac joint fusion is characterized by a longitudinal bone screw and a cylindrical sleeve received on a proximal end of the bone screw. The sleeve has axially extending fins or flutes on its outer surface that extend generally from one end of the sleeve to the other end of the sleeve. This feature allows the sleeve to resist reverse rotation which, in turn, aids in preventing back-out of the bone screw once installed. The bone screw has a self-tapping tip that allows the bone screw to be installed without need for a pilot hole, and self-harvesting geometry that gathers and retains bone shavings in and along the bone screw that are produced by bone screw installation for use as graft for bone fusion.

The present invention generally relates to bone implants. More specifically, the present invention relates to bone implants used for the fixation and or fusion of the sacroiliac joint and/or the spine. For example, a system for fusing and or stabilizing a plurality of bones is provided. The system includes an implant structure having a shank portion, a body portion and a head portion. The body portion is coupled to the shank portion and is configured to be placed through a first bone segment, across a bone joint or fracture and into a second bone segment. The body portion is configured to allow for bony on-growth, ingrowth and through-growth. The head portion is coupled to the proximal end of the shank portion and is configured to couple the shank portion to a stabilizing rod. Methods of use are also disclosed.

The present invention involves a device and method for restoring intervertebral height and promoting bone fusion to maintain the proper height. The present invention is an interspinous device comprised of two clamps and an elongated element for use in spinal surgery to separate adjacent vertebrae. Once deposited in the intervertebral space, the device effects spinal fusion over time as the natural healing process fuses the bone through and around the device.

Interspinous device and related methods

The present invention relates generally to medical devices and methods for use in spinal surgery. In particular, the disclosed system relates to an intervertebral spinal implant assembly sized and dimensioned for the lumbar or cervical spine implantable via an anterior approach. The device includes an implant, bone fasteners, and instruments for delivering the implant and bone screws.
