An anatomy-specific implant for neuroplastic surgery. The implant includes a soft tissue implant component designed within and adapted to replace or restore missing soft tissue in a skull, joint or spine of the patient, wherein the soft tissue implant component is adapted to be coupled by an interdigitated connection to a rigid component. The rigid component can be a skull implant adapted to replace missing cranial or vertebral bone, or healthy cranial or vertebral bone, either of which can have downward extending catheters for medicinal brain or spinal cord infusion to help bypass the blood-brain barrier via multiphase flow. The soft tissue implant may include a functional component having neurotechnologies such as MRI-lucent pumps, Bluetooth connection systems, refillable diaphragms, remote imaging devices, wireless charging capabilities, and/or informative biosensors. The soft tissue implant component may be interchangeable with another soft tissue implant component in plug-and-play fashion.

A joint implant component (1, 1′; 101; 201) for administering a pharmaceutical product is disclosed, which comprises an implant shaft (10, 10′; 110; 210), a joint section (20, 20′; 120; 220) arranged at the proximal end of the implant shaft, a flush supply opening (3, 3′; 103; 203) and a backflush opening (4, 4′; 104; 204). At least one shaft flush channel (11, 11′; 111; 211) and one shaft backflush channel (12, 12′; 112; 212) extend along the implant shaft inside the implant shaft. The shaft flush channel is connected to the outside of the implant shaft via shaft flush holes (13, 13′; 112; 113) for discharging the pharmaceutical product, and the shaft backflush channel is connected to the outside of the implant shaft via at least one shaft backflush hole (14, 14′; 114; 214) for receiving the discharged pharmaceutical product. The flush supply opening is fluidically connected to the proximal end of the shaft flush channel and the backflush opening is fluidically connected to the proximal end of the shaft backflush channel. Also disclosed is a joint implant comprising two such joint implant components which are connected to one another by means of joint surface parts (30, 40; 230) and are pivotable relative to one another.

An orthopaedic implant with a medical dosing capability is disclosed herein. The orthopaedic implant may include a structure configured to interact with a bone of the patient. The orthopaedic implant may include a reservoir associated with the structure to hold a medical substance for treating a health condition of the patient. The orthopaedic implant may include a dosing mechanism to release the medical substance to treat the health condition.

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.

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.

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.

A spacer for a knee replacement prosthesis may be provided. The spacer may include a lower surface, the lower surface having a locking component adapted to interlock with a tibial tray; an upper surface, the upper surface having an optional central femoral guide and a pair of condyle support platforms, each of the condyle support platforms being disposed on an opposite side of the central femoral guide, each of the condyle support platforms being smooth, the surface of each of the condyle support platforms further having a shallow concavity; and a body incorporating the upper and lower surfaces, the body having a hollow outer portion surrounding an internal reservoir, the body being impermeable to fluid; the body further having one or more ports, each with a channel, each channel extending through the hollow outer portion of the body directing the flow of fluid in and out of the port(s).

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.
