Method and device for ameliorating joint conditions and diseases
A device for ameliorating joint conditions and diseases comprising a) a first section comprising a joint-ward end, an opposing mating end, and a lateral wall, a peripheral column partially forming the lateral wall of the first section, a central column, and three or more than three struts extending between and connecting the peripheral column and the central column, and each strut thereby supporting the central column, the joint-ward end further comprising a plurality of fenestrations formed by a confluence of the peripheral column, the central column and two adjacent struts of the three or more than three struts, and first section further comprising a central aperture within and formed by the central column, and configured to mate with a driver, b) a second section comprising a mating end, an opposing leading end, and a lateral wall, the lateral wall of the second section comprising threads.
1. A method for ameliorating a joint condition or disease in a patient, the method comprising:
a) identifying a patient with a joint condition or disease that is suitable for treatment by the method, where the joint comprises a bone with a surface comprising a defect caused by the joint condition or disease;
b) accessing the joint;
c) placing a guidepin within the center of the defect;
d) creating a space in the defect of the bone;
e) providing a first device for ameliorating joint conditions and diseases, the first device comprising:
i) a first section comprising a joint-ward end, an opposing mating end, and a lateral wall extending between the joint-ward end and the mating end;
where the first section further comprises a peripheral column partially forming the lateral wall of the first section, a central column, and three or more than three struts, each strut extending between and connecting the peripheral column and the central column, and each strut thereby supporting the central column;
where the joint-ward end further comprises a plurality of fenestrations, where each fenestration is formed by a confluence of the peripheral column, the central column and two adjacent struts of the three or more than three struts; and
where the first section further comprises a central aperture within and formed by the central column, and configured to mate with an introducer; and
ii) a second section comprising a mating end, an opposing leading end, and a lateral wall extending between the mating end and the leading end;
where the lateral wall of the second section comprises threads;
where the first device comprises an axial length of between 5 mm and 30 mm;
where the first section further comprises a diameter of between 5 mm and 30 mm;
where the leading end comprises a scalloped edge and bevels; and
where the lateral wall of the second section further comprises a plurality of fenestrations between the threads;
f) attaching the first device to a driver by mating a distal end of the driver with the central aperture of the first device; and
g) screwing the first device into the space using the driver until the joint-ward end of the first device forms a shape that substantially recreates a shape of the bone surface at an articulation area after implantation.
2. The method of claim 1 , where the joint is selected from the group consisting of an acetabulofemoral joint, an acromioclavicular joint, a femoropatellar joint, a femorotibial joint, a glenohumeral joint, a humeroradial joint, a humeroulnar joint, an interphalangeal joint, a metacarpal joint, a radioulnar joint and a talocrural joint.
3. The method of claim 1 , where the joint condition and disease is selected from the group consisting of arthroses, chondromalacia patella, isolated chondral defect, juvenile idiopathic arthritis, ligamentous deficiency arthroses, osteoarthritis, degenerative arthritis, degenerative joint disease, osteonecrosis, osteochondritis dissecans, patellar instability, post-ligamentous injury arthritis, post-meniscectomy arthritis, post-meniscectomy arthroses, post-traumatic arthritis, rheumatoid arthritis and septic arthritis.
4. The method of claim 1 , where identifying the patient comprises diagnosing the patient with a joint condition and disease by performing one or more than one action selected from the group consisting of performing a physical examination, performing a non-invasive imaging examination and performing arthroscopy.
5. The method of claim 1 , where identifying the patient comprises consulting patient records to determine if the patient has a joint condition or disease suitable for treatment by the method.
6. The method of claim 1 , where accessing the joint is accomplished by arthroscopy or by an open surgical procedure.
7. The method of claim 1 , where the surface of the bone comprises one or more than one abnormality, and where the method further comprises using a burr, or a suction shaver, or both a burr and a suction shaver to remove some or all of the one or more than one abnormality thereby creating a smoother articulation surface.
8. The method of claim 1 , further comprising creating one or more than one vascular channel in the bone deep to the space using a drill bit guide positioned over the guidepin and a drill bit passed within the drill bit guide.
9. The method of claim 1 , further comprising injecting a biological material in the first device.
10. The method of claim 1 , further comprising placing an insert in the first device.
11. The method of claim 1 , further comprising placing one or more than one additional device in the defect.
12. The method of claim 1 , where the peripheral column comprises one or more than one notch.
13. The method of claim 1 , where the lateral wall of the second section is generally cylindrical.
14. The method of claim 1 , where the lateral wall of the second section is generally conical, tapering between the mating end and the leading end.
