An interspinous fusion device is described. The interspinous fusion device includes a spacer member and an anchor member. The spacer member has a ring with two or more anchor assemblies projecting laterally from substantially opposite sides of the spacer member ring. The spacer member further has a first zip lock flange and a second zip lock flange, each of the first and second zip lock flanges extends transversely from the spacer member ring wherein each of the first and second zip lock flanges each comprises a series of teeth protruding from it. The anchor member has a ring with two or more anchor assemblies projecting laterally from substantially opposite sides of the anchor member ring. The anchor member further has a barrel extending transversely from the anchor member ring. The barrel comprises a first column of recesses adapted to mate with the teeth of the first zip lock flange and a second column of recesses adapted to mate with the teeth of the second zip lock flange. The spacer member is adapted to slide over the barrel of the anchor member such that the series of teeth of the first zip lock flange mates with the recesses in the first column of recesses of the barrel, and the series of teeth of the second zip lock flange mates with the recesses in the second column of recesses of the barrel to secure the spacer member to the anchor member.

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.

Embodiments of the present technology pertain to a system for hyper-localized immobilization of a bone structures. In various embodiments the system includes a power supply, the power supply being internal or external to a patient and allowing for variable control of electric current from the power supply. Embodiments further include a first micro-electromagnet being internal to the patient and being placed in a first bracket that is secured to a first side of the bone structure generating half of an electromagnetic attractive force that will immobilize the other bone structure when a second micro-electromagnet being internal to the patient is placed in a second bracket that is secured to a second side of the bone structure generating the electromagnetic attractive force that immobilizes the bone structure. This method could be applied to stabilize or fixate bone fracture sites when electromagnets leverage attractive forces.

An apparatus for controlling a degradation rate of an artificial bone in vitro, a degradation method, and an artificial bone are disclosed. The apparatus includes: a variable resistor; and a wearable component, comprising: a metal wire electrically connected in series with the variable resistor and configured to generate an alternating magnetic field; and an insulating textile layer by which the outside of the metal wire is covered.

The present application relates to stacked piezoelectric composites comprising piezoelectric structures. Suitably, the composites are useful as tissue-stimulating implants, including spinal fusion implants. The present application also relates to methods of making stacked piezoelectric composites.

There is described a bone implant comprising at least one means for providing at least one bone stimulation dynamic interaction to at least one area of a bone-implant interface formed when the implant is inserted into bone, wherein the bone stimulation is one or more of bone growth, bone strengthening, bone densification and/or osseointegration between bone and the bone-implant interface.

An interspinous fusion device is described. It includes a first member with a column of teeth, and a second member with a column of recesses adapted to mate with the column of teeth of the first member. The first member and the second member have opposing windows on their walls, such that when the first member is mated with the second member an unobstructed passage is formed through the opposing windows. The first member and the second member lock together when the teeth and recesses are mated, said locking occurring without the aid of a set screw, pin or other mechanical component.

A system and method for electrical stimulation in an orthopedic implant that includes at least one implantable component with an implant body, a plurality of electrodes, and implant circuitry is effective to convert an external wireless power transmission to an electrical current and effective to control the plurality of electrodes; and at least one non-implant with a power source, and transmitter circuitry to generate the electromagnetic field that couples with the implant circuitry.
