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.

Methods are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. In one embodiment, a defect creation assembly is advanced from a posterior approach into the SI joint and configured to create pilot SI joint opening; portions of which being disposed in the sacrum and ilium bone structures. After the pilot SI joint opening is created, a prosthesis is press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures.

Systems are described for stabilizing a dysfunctional sacroiliac (SI) joint of a subject. The systems include a tool assembly and a defect creation assembly, and a prosthesis. The tool assembly is adapted to create a pilot SI joint opening in the dysfunctional SI joint; portions of which being disposed in the sacrum and ilium bone structures. The prosthesis is sized and configured to be press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures. The system optionally includes an image capture apparatus adapted to capture images reflecting positions and/or orientations of the tool assembly when disposed in the subject's body.

An implant system for correcting deformities is provided. The implant system includes A proximal extension having a hollow interior and a distal extension configured to be received within the hollow interior of the proximal extension. The implant system also includes a locking element configured to lock the distal extension from moving with respect to the proximal extension. The distal extension is configured with ratchet teeth on a top surface for interacting with a distractor instrument for contacting or distracting the distal extension with respect to the proximal extension. The proximal extension and distal extension are configured to receive clamping elements for coupling to the implant to anatomical regions of the body.

A posterior cervical fixation system including an occipital plate member, a cross connector, a pair of elongated spinal rods and a plurality of polyaxial screws. The occipital plate member configured for fixing to an occipital bone comprises an aperture to receive a bone anchor member to secure the occipital plate member to the occipital bone and at least one rod clamping element dimensioned to receive at least one spinal rod. The cross connector secures the pair of elongated spinal rods to vertebral bodies. The cross connector includes a pair of collet connectors and a cross bar that is configured to secure the pair of elongated spinal rods in a desired distance. Each polyaxial screw has an anchor head associated with a fastening member. The pair of elongated spinal rods is configured to extend along the vertebral bodies between the occipital plate member and at least one of the polyaxial screws.

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.

A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

An occipital plate and hinged rod assembly. The occipital plate having a screw-attachment section having through holes for securing the occipital plate to a skull, a laterally-extending section, a tulip connector, a slide clip disposed underneath the laterally-extending section and engaging a base of the tulip connector, and an insert ring encompassing side walls of tulip connector. The laterally-extending section, the tulip connector, the slide clip, and the insert ring have respective surfaces with complementary curvatures that fit together. The hinged rod assembly is connected to the occipital plate by rods.

A sacroiliac joint fusion screw and associated delivery tools and method. Embodiments of the sacroiliac joint fusion screw comprise a shaft having proximal and distal end portions and a head on the proximal end of the shaft. A threaded portion on a distal portion of the shaft is configured to engage a sacrum. A glide zone portion on the shaft between the threaded portion and the proximal end portion is configured to extend through an ilium. The screw can provide stability and compression to the joint.

A fixation implant includes a head, a shank and a distal tip, and one or more of the head, shank and distal tip may be cannulated. The shank includes a threaded ingrowth portion extending from the head to the tapered distal tip that includes external threads, and at least one open network body extending along the length of the ingrowth portion. The open network body selected from one or a combination of a helix, an arrangement of trusses, a scaffold of open and interconnected pores, a porous framework of random open and interconnected pores, and combinations of these.
