A method for preparing a sacroiliac joint for stabilization which may include approaching a posterior aspect of the sacroiliac joint inferior to a PSIS with a defect-creating tool assembly, creating a defect in the sacrum and the ilium defined by at least one noncircular cross-sectional shape, delivering an implant having a body with a length extending between proximal and distal ends, the body including at least one cylindrical body with a longitudinal axis and an opening at the proximal end aligned with the longitudinal axis of the cylindrical body, a pattern of openings spaced along the cylindrical body and a planar member coupled with and extending along the cylindrical body. The implant may be implanted with the length generally following a plane of the sacroiliac joint such that it is advanced from a generally posterior to anterior approach while the body of the implant bridges the joint.

Various embodiments of intervertebral implants, anchoring devices for intervertebral implants, and implantation instrumentation are provided, along with various embodiments of methods for using one or more of the devices. Some embodiments of an anchoring device have a body comprising at least one curve and a rigid plate elongated along a longitudinal axis so that its front end enters at least one vertebra while its rear end remains in the passage of an implant. In some embodiments, the plate comprises at least one longitudinal slot separating at least one posterior portion of the plate into two branches, with at least one branch comprising at least one withdrawal stop configured to retain the device in the implant.

A method of treating a sacroiliac joint at a sacroiliac joint region having a sacrum, an ilium and a sacroiliac joint space therebetween, the method comprising: a) delivering a joint implant into the sacroiliac joint region, the joint implant comprising a body including a length extending between a proximal end and a distal end, an external surface extending the length, and a fixation member receiving channel extending the length and disposed in the external surface; and b) delivering a fixation member into the fixation member receiving channel thereby forming a joint implant assembly, the fixation member slidingly and matingly engaging the fixation member receiving channel in a grooved arrangement, wherein, when the fixation member is received into the fixation member receiving channel, the fixation member extends outward from the external surface of the joint implant and extends a portion of the length.

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 vis-?-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.

An interbody fusion device includes a base member, a top member, and an expansion mechanism for moving the top member relative to the base member. The expansion mechanism may include a connector drive rod assembly, a gear, a threaded rod, and a support means. The gear ring is coupled to the threaded rod and is rotatable. The expansion mechanism may also include at least one load head coupled to the threaded rod. An alternative interbody fusion device is also disclosed and includes a bottom member, a superior member, and an expansion mechanism for moving the superior member relative to the base member, wherein the expansion mechanism comprises at least one expansion assembly for moving an end of the superior member relative to the bottom member.

A sacroiliac joint fusion system that provides a method of fixation and fusion of the sacroiliac joint and sacroiliac fixation fusion implant which upon placement facilitates stability and fusion of the sacroiliac joint.

A method of fusing a sacroiliac joint including a sacrum, an ilium, and a sacroiliac joint space defined therebetween. The method may include: approaching a posterior aspect of the sacroiliac joint space with a joint implant including a body extending a length between a distal end and a proximal end; and delivering the joint implant into the sacroiliac joint space such that the joint implant passes through an access region defined between the posterior superior iliac spine and the posterior inferior iliac spine. The joint implant may be oriented in the sacroiliac joint space such that a portion of the body of the joint implant is positioned within a joint plane of the sacroiliac joint space, and such that the distal end of the joint implant is positioned posteriorly of an anterior boundary of the sacroiliac joint space.

A bodiless bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bodiless bone fusion device comprises one or more extendable plates, one or more extending blocks in communication with the extendable plates, one or more positioning elements for adjusting the extendable plates by manipulating the extending blocks, and one or more support panels for holding the positioning elements and guiding the extendable plates. The plates are able to be advantageously positioned in the confined space between the vertebrae to help brace the device until the bone has fused.

An interbody fusion device including a body member, at least one side member engaging the body member, and at least one movement mechanism that engages at least one side member and the body member. A surgical method for maintaining a space between two vertebral bodies in a spine, including the steps of obtaining a medical device, such as an interbody fusion device, and inserting and coupling an expansion tool into an opening within the medical device. The surgical method also including slidingly inserting the medical device into a space between two vertebral bodies and rotating the expansion tool to move the at least one side member in a direction relative to the body member. The method may further include detaching the expansion tool from the medical device and removing the tool from the space between the two vertebral bodies in the spine.

Various systems and methods are disclosed for joining at least two components of a prosthesis. For example, a system may include a first component having a first a first body extending from a first face to a second face. An engagement element may be disposed on the first face of the first body and may be configured to engage a second component. A biasing member may be disposed on the engagement element and may be configured to latch a second component to the first component. A securing mechanism may be configured to receive a locking mechanism at an angle with respect to a longitudinal axis. The locking mechanism may be adapted to interact with the biasing member.
