Abstract:
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.
