Patent number: 10596002Abstract: A method of performing an orthopedic procedure in the sacroiliac region. At least one aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is at least partially 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 sharper than the probe assembly. 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: 9717586Abstract: The present invention has multiple aspects relating to a bone-tendon-bone graft and components thereof. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. The present invention further relates to an assembled bone-tendon-bone graft suitable for implantation in humans comprising the intermediate bone block and a length of soft tissue. In a preferred embodiment, a bone-tendon-bone graft comprises a length of soft tissue (e.g., tendon) extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block. Depending upon the embodiment, the second bone block fixedly or slideably attaches to the length of soft tissue and facilitates it doubling back to the first assembled bone block.Type: GrantFiled: June 7, 2013Date of Patent: August 1, 2017Assignee: RTI Surgical, Inc.Inventors: John R.
