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 drill assembly is advanced from a posterior approach into the SI joint to create a 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 SI joint prosthesis is inserted into the pilot SI joint opening, wherein the SI joint prosthesis is positioned in the dysfunctional SI joint at a distance of at least 3.0 mm away from the SI joint dorsal recess.

A surgical instrument for operating hip joint osteoarthritis in a human patient is provided. The hip joint comprises an acetabulum, being a part of the pelvic bone, and a caput femur, being the proximal part of the femoral bone. The surgical instrument is adapted to assist in the operating of the hip joint osteoarthritis from the abdominal side of the pelvic bone of said human patient.

Methods are described for stabilizing dysfunctional bone structures. The methods include the step of providing prostheses having an elongated body with dual, i.e., first and second, threaded ends and an intervening central region. The threaded ends have helical threads wound thereon that extend from the intervening central region to the ends of the first and second threaded ends. The methods further include the steps of creating a pilot opening in the dysfunctional bone structures and inserting the prostheses into the pilot opening and, thereby dysfunctional bone structure.

A medical device for delivering an action to an area of a hip joint or its surroundings, inside a human body, is provided. The hip joint of a patient comprises a collum femur and a ball shaped caput femur, being the proximal parts of the femoral bone, and an acetabulum, being a bowl shaped part of the pelvic bone. The medical device comprising; an elongated member, having a length axis along its elongated distribution, comprising a first portion, adapted to enter the body of the patient, and a mechanical element, adapted to be used during an operation in the hip joint or its surroundings, inside the body. The first portion of the elongated member comprises a holding member adapted to hold the mechanical element inside the body of the patient, wherein the first portion of the elongated member have a first portion cross-section area substantially perpendicular to the length axis of the elongated member. The first portion is adapted to pass through a hole, in a bone of the patient, the hole having a hole cross-section area. The first portion cross-section area, is adapted to be smaller than said hole cross-section area. The mechanical element have a functional status, ready to deliver said action inside said body, when held by the holding member inside the body of the patient. The mechanical element is adapted to have a mechanical element cross-sectional area substantially perpendicular to the length axis of the elongated member, substantially larger than the first portion cross-sectional area and adapted to be unable to pass through the hole, when the mechanical element is in the functional status.

The present disclosure provides an implant system. The implant system includes an anchor configured to be secured to bone within an excision site formed in a patients glenoid, said anchor including a shank and an enlarged head. The implant system also includes a baseplate including a body comprising: a bone facing surface; an implant facing surface; and a channel configured to extend radially from an entrance in an outer periphery of said body to a central region of said baseplate, said channel configured to receive said enlarged head and a portion of said shank and including an open region formed, at least in part, in said bone facing surface. The implant system also includes an implant including a body defining a load bearing surface and a baseplate recess, said baseplate recess configured to receive at least a portion of said implant facing surface to said baseplate such that said implant is coupled to said baseplate.

Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, and a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint.

Methods are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The methods include the initial steps of providing a drill guide assembly adapted to create a pilot opening in the dysfunctional SI joint, a prosthesis configured to be inserted into the pilot opening created by the drill guide assembly and a prosthesis deployment assembly adapted to engage and advance the prosthesis into the pilot opening in the dysfunctional SI joint. The drill guide assembly includes a drill guide having a prosthesis access opening therethrough; the opening having a configuration that corresponds to the shape of the prosthesis. In some aspects of the invention, the methods thus include the step of advancing the prosthesis through the drill guide and then into the pilot opening in the dysfunctional SI joint with the prosthesis deployment assembly; the initial advancement of the prosthesis through the drill guide providing consistent, optimal placement of the prosthesis in the dysfunctional SI joint.
