Configurations are described for conducting minimally invasive medical interventions utilizing elongate instruments and assemblies thereof to stabilize and/or fixate a sacro-iliac joint. In one embodiment, a tool assembly may be advanced from a posterior approach into the SI junction and configured to create a defect defined at least in part by portions of both the sacrum and the ilium, the defect having a three dimensional shape defined in part by at least one noncircular cross sectional shape in a plane substantially perpendicular to the longitudinal axis of the tool assembly. After a defect is created, the tool assembly may be retracted and a prosthesis deployed into the defect.

System for sacro-iliac stabilization

Implants for the fusion or fixation of two bone segments are described. For example, the implants can be used for the fusion or fixation of the sacroiliac joint. The implants can include fenestrations, have a rectilinear overall cross-sectional area, and have a curvature. Some implants can also be used to rescue failed implants.

Implants for bone fixation or fusion

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.

Methods of fusing a sacroiliac joint

Method for sacro-iliac stabilization

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

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.

Systems, device, and methods for joint fusion

The present invention relates generally to tissue dilators and protectors. More specifically, this application relates to tissue dilators and protectors used in medical procedures such as bone fixation or fusion. One embodiment of a soft tissue protector includes a port for coating an implant with a biologic aid. One embodiment of an expandable dilator includes a plurality of slidably connected longitudinal wall segments. One embodiment of a delivery sleeve includes a flexible tapered portion configured to expand.
