  • Patent number: 11173036
    Abstract: Methods and apparatuses for performing an orthopedic procedure in the sacroiliac region are disclosed. In one form, an aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is inserted into the aperture. The undercutting system includes an insertion apparatus, a probe assembly and a cutting assembly. The probe assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The probe assembly is manipulated within a joint between the ilium and the sacrum while the probe assembly is in the extended position. The cutting assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The cutting assembly is manipulated within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region.

  • Patent number: 9861375
    Abstract: An undercutting system for preparing a region between an ilium and a sacrum for sacroiliac fusion. The undercutting system includes an insertion apparatus and a cutting assembly. The cutting assembly is operably mounted with respect to the insertion apparatus. The cutting assembly has a distal end and a proximal end. The cutting assembly includes a plurality of cutting elements and a cutting element attachment mechanism. The cutting element attachment mechanism engages the cutting elements to operably mount the cutting elements with respect to the insertion apparatus. The cutting element attachment mechanism permits the cutting elements to pivot with respect to each other.

  • Patent number: 9017389
    Abstract: A method of treating a facet joint of a patient. The facet joint includes a superior facet having superior articular face and an inferior facet having an inferior articular face. A distal end of an implant delivery cannula is extended between the superior and inferior articular faces. The implant delivery cannula has a channel extending therethrough. An implant is moved through the channel until the implant is between the superior and inferior articular faces while at least a portion of the implant is within the channel. The implant includes a first surface and a second surface. The implant delivery cannula is moved away from the superior and inferior articular faces so that the first surface is adjacent the superior articular face and the second surface is adjacent the inferior articular face.
