A method for implanting a medical device for implantation in a mammal joint. The method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing said artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting said reservoir in the human body, and lubricating the artificial contacting surface with use of a lubricating fluid contained in said reservoir.

A method of guiding a glenoid prosthesis is disclosed. The method includes pre-operatively determining a position and an orientation of a guide feature of a glenoid guide of the present disclosure based on a scapula of a specific patient, and engaging the glenoid guide with the scapula; and inserting a pin having an axis through the guide feature to or through the scapula.

Prostheses are described for stabilizing dysfunctional bone structures. The prostheses have proximal and distal ends, and an expandable mid-region disposed therebetween. The expandable mid-region includes a plurality of deflectable elongate members that are configured and adapted to transition from a compressed configuration to a deflected configuration when released from a deployment apparatus, whereby the plurality of deflectable elongate members deflects outwardly when the elongated member is inserted into a pilot opening of a dysfunctional bone structure, whereby the plurality of elongate members exerts a retaining force on the internal surface of the pilot opening and secures the elongated member in the pilot opening and, thereby, the dysfunctional bone structure.

A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

A medical device for implantation in a hip joint of a human patient, the natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the center of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the center of the hip joint. The medical device comprising; an artificial caput femur, comprising a convex surface towards the center of the hip joint. The artificial convex caput femur is adapted to, when implanted: be fixated to the pelvic bone of the human patient, and be in movable connection with an artificial acetabulum surface fixated to the femoral bone of the patient, thereby forming a ball and socket joint. The medical device further comprises a fixation element comprising a fixation surface adapted to be in contact with the surface of the acetabulum and adapted to fixate the artificial convex caput femur to at least the acetabulum of the pelvic bone.

A humeral implant is provided. The implant includes a humeral stem including a plurality of fins. At least one fin comprises a serrated bottom edge. A radial distance between an inner bottom edge of the at least one fin and a centerline of the humeral implant increases along a distal length of extension of the at least one fin. At least the serrated bottom edge of the at least one fin is configured to cut into and compact bone of the metaphysis of a humerus toward relatively denser cancellous bone of a peripheral portion of the humerus when press-fit therein, thereby providing sufficient press-fitting for cementless fixation of the humeral stem into the humerus. Related kits and methods are also provided.

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 defect creation assembly is advanced from a posterior approach into the SI joint and configured to create 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 prosthesis is press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures.

Systems are described for stabilizing a dysfunctional sacroiliac (SI) joint of a subject. The systems include a tool assembly and a defect creation assembly, and a prosthesis. The tool assembly is adapted to create a pilot SI joint opening in the dysfunctional SI joint; portions of which being disposed in the sacrum and ilium bone structures. The prosthesis is sized and configured to be press-fit into the pilot SI joint opening, wherein the pilot SI joint opening transitions to a larger post-prosthesis insertion SI joint opening and the prosthesis is securely engaged to the sacrum and ilium bone structures. The system optionally includes an image capture apparatus adapted to capture images reflecting positions and/or orientations of the tool assembly when disposed in the subject's body.
