Resilient knee implant and methods

Принадлежит: Grotz R Thomas

This disclosure is directed to a resilient interpositional arthroplasty implant for application into a knee joint to pad cartilage defects, cushion a joint, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. Rather than using periosteal harvesting for cell containment in joint resurfacing, the walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability to avoid extrusion or dislocation. Appendages of the implant may repair or reconstruct tendons or ligaments, and an interior of the implant that is inflatable may accommodate motions which mimic or approximate normal joint motion.

Принадлежит: Otismed Corp

A method and system for performing a total joint arthroplasty procedure on a patient's damaged bone region. A CT image or other suitable image is formed of the damaged bone surfaces, and location coordinate values (x n ,y n ,z n ) are determined for a selected sequence of bone surface locations using the CT image data. A mathematical model z=f(x,y) of a surface that accurately matches the bone surface coordinates at the selected bone spice locations, or matches surface normal vector components at selected bone surface locations, is determined. The model provides a production file from which a cutting jig and an implant device (optional), each patient-specific and having controllable alignment, are fabricated for the damaged bone by automated processing. At this point, the patient is cut open (once), the cutting jig and a cutting instrument are used to remove a selected portion of the bone and to provide an exposed planar surface, the implant device is optionally secured to and aligned with the remainder of the bone, and the patient's incision is promptly repaired.

A plate having unique anatomical brim specific shape and enables dual cortical fixation i.e. fixation from outer cortical region and inner cortical region, in a quick and easy manner is disclosed. Dual cortical fixation using nut and bolt enables compression (grip), enabling repair of fractures in normal as well as osteoporotic bone. The plate rests on to brim of pelvic so that a single screw or more screws can be inserted into it from the outer cortex of the bone that comes out of the brim, as brim is the strongest portion and holds the screws well. The screws are held into the bone using bi-cortical fixation by means of cannulated screws which are provided with washers to increase surface area of contact with bone. Owing to ease of use, the plate drastically reduces surgery time from few hours to less than an hour. 414. The plate as claimed in claim 1 , wherein out of the plurality of holes present in the upper extended portion claim 1 , two holes viz. F and F as illustrated in are locking holes with screw threads.514.
