Claims
- 1.A system comprising:
- 2.The system of claim 1 wherein the orthopedic hardware component is a bone screw.
- 3.The system of claim 2 wherein the bone screw includes a head, the sustained release device being formed in a chamber in the head.
- 4.The system of claim 2 wherein the bone screw is at least one of a cannulated bone screw and an interference bone screw.
- 5.The system of claim 1 wherein the orthopedic hardware component is at least one of a staple, a tack, a dart, a screw, a bolt, a washer, a plate, a prosthetic joint, a component of a prosthetic joint, an anchor, a pin, a wire, or a button.
- 6.The system of claim 1 wherein the orthopedic hardware component is substantially rigid and is configured for at least partial insertion into a bone.
- 7.The system of claim 1 wherein the sustained release device is removably associated with the orthopedic hardware component.
- 8.The system of claim 7 wherein the sustained release device is threaded to the orthopedic hardware component such that the sustained release device is rotatably removable from and replaceable to the orthopedic hardware component.
- 9.The system of claim 8 wherein the sustained release device is a cap threaded to an outward projecting surface of the orthopedic hardware component.
- 10.The system of claim 8 wherein the sustained release device is a screw threaded to an inwardly projecting surface of the orthopedic hardware component.
- 11.The system of claim 7 wherein the sustained release device is attached to the orthopedic hardware component using an interference fit.
- 12.The system of claim 7 wherein the sustained release device includes a first suture eye and the orthopedic hardware component includes a second suture eye, the sustained release device being attached to the orthopedic hardware component using a suture through each of the first suture eye and the second suture eye.
- 13.The system of claim 7, the orthopedic hardware component including a chamber, the sustained release device configured for placement in the chamber of the orthopedic hardware component.
- 14.The system of claim 1 wherein the sustained release device is integrally formed with the orthopedic hardware component.
- 15.The system of claim 1 wherein the compound is a low-solubility compound.
- 16.The system of claim 15 wherein the compound comprises a matrix of an effective agent and a polymer that is permeable to the effective agent.
- 17.The system of claim 15 wherein the sustained release device includes an inner core containing the compound, the sustained release device further comprising a non-bioerodible polymer coating layer, the non-bioerodible polymer coating layer being permeable to the compound, wherein the non-bioerodible polymer coating layer covers the inner core and is essentially non-release rate limiting.
- 18.The system of claim 1 wherein the compound comprises a soluble compound.
- 19.The system of claim 18 wherein the compound is surrounded by an outer layer that covers the compound and includes a first surface and a second surface, the first surface being substantially impermeable to the compound and the second surface being permeable to the compound and limiting a release rate of the compound.
- 20.The system of claim 1, the compound including at least one of a steroid, an antibiotic, an anti-inflammatory drug, an antiproliferative compound, an antimyotic compound, an antimitotic compound, an antimetabolite compound, a pain-relieving drug, a corticosteroid, an angiostatic steroid, a non-steroidal anti-inflammatory agent, or a co-drug.
- 21.The system of claim 1, the therapeutic effect including at least one of an anti-inflammatory effect, a pain-relief effect, an anesthetic effect, an immune suppressant effect, an antibiotic effect, an anti-viral effect, a cancer-fighting effect, an anti-cancer effect, an anti-proliferative effect, a cartilage-protecting effect, or an anti-scarring effect.
- 22.A system comprising:
- 23.A method comprising:
- 24.The method of claim 23 wherein attaching the orthopedic hardware component further comprises screwing the component into a bone of the body;
- 25. 27.The method of claim 23 wherein the orthopedic hardware component includes at least one of a staple, a tack, a dart, a bolt, a washer, a plate, a prosthetic joint, a component of a prosthetic joint, an anchor, a pin, a wire, or a button.
- 26. 28.The method of claim 23 wherein associating the compound with the orthopedic hardware component further comprises removably attaching a sustained release device that includes the compound to the orthopedic hardware component using at least one of threads that rotatably engage the sustained release device to the orthopedic hardware component, an interference fit between the sustained release device and the orthopedic hardware component, a pin passing through the orthopedic hardware component and the sustained release device, or a suture passing between a suture eye of each one of the orthopedic hardware component and the sustained release device.
- 27. 29.The method of claim 23 wherein the compound is a low-solubility compound, releasing the compound further comprising exposing the compound to a bodily fluid such that the compound dissolves into the bodily fluid.
- 28. 30.The method of claim 23 wherein the compound is a high-solubility compound, releasing the compound further comprising exposing the compound to a bodily fluid through a membrane that limits a rate of release of the compound.
- 29. 31.The method of claim 23 wherein the compound includes at least one of a steroid, an antibiotic, an anti-inflammatory drug, an antiproliferative compound, an antimyotic compound, an antimitotic compound, an antimetabolite compound, a pain-relieving drug, a corticosteroid, an angiostatic steroid, a non-steroidal anti-inflammatory agent, or a co-drug.
- 30. 32.The method of claim 23 wherein the therapeutic effect includes at least one of an anti-inflammatory effect, a pain-relief effect, an anesthetic effect, an immune suppressant effect, an antibiotic effect, an anti-viral effect, a cancer-fighting effect, an anti-cancer effect, an anti-proliferative effect, a cartilage-protecting effect, or an anti-scarring effect.
- 31. 33.The method of claim 23 wherein attaching the orthopedic hardware component comprises attaching the component within a synovial capsule of a joint, the compound including one or more treatments for at least one of osteoarthritis or rheumatoid arthritis.
