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 spinal construct comprises a fastener attached with sacral and/or pelvic tissue of a body. A connector is selectively movable in a coronal plane relative to the body. The connector has a first end connected with the fastener and a second end having a locking surface engageable with an implant. A lock element is engageable with the connector and defines an implant cavity. Systems and methods are disclosed.

Embodiments of the present invention relate generally to implant placement into bone. More specifically, embodiments of the invention relate to implant placement across the sacro-iliac joint. Placement can be facilitated using various CT imaging views that allow the implants to be placed in bone associated with articular cartilage.

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.

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a mounting ring which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the mounting ring and the clip.

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.

Systems for and methods of fusing a sacroiliac joint are provided which may include an implant adapted to be inserted into the joint space defined by the bones of a sacrum and an ilium and a delivery tool for inserting the implant into the sacroiliac joint. The method may include delivering the implant into the SI joint in a first position and transitioning the implant from the first position to a second position in situ. The implant may be configured such that in the second position the implant generally mimics a shape of the joint space of the sacroiliac joint. The implant may further include an actuation mechanism configured to cause the implant to transition from the first position to the second position. The actuation mechanism may include a hydraulic, pneumatic, geared or screwed mechanical arrangement.

The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

Threaded sacro-iliac joint stabilization (e.g., fusion, fixation) implants and methods of implantation and manufacture. Some implants include a threaded distal region, an optionally threaded central region, and an optionally threaded proximal region. The distal, central, and proximal regions have lengths such that when the implant is laterally implanted across a SI joint, the distal region can be positioned in a sacrum, the central region can be positioned across an SI-joint, and the proximal region can be positioned in an ilium.
