With a total of 2 patents to his name, Amundsen's work is paving the way for advancements in surgical techniques and patient outcomes.

Latest Patents

One of Amundsen's latest patents is a method of enhancing interdigitation of bone cement to bone for the attachment of prosthesis to bone during arthroplasty. This innovative method is applicable to various bones, including the tibia, patella, acetabulum, glenoid, and femur. The process involves trimming an articular surface of the bone to create a trimmed surface. Holes are then punched or drilled into this surface in a predetermined array before polymethyl methacrylate bone cement is applied to attach the surface to the implant. In one embodiment, holes are punched using a punch-plate with sharpened spikes, while in another, a drilling template with predrilled guidance holes is utilized. Additionally, a robotic drill can be positioned over the trimmed surface to adjust the drilling pattern according to the specific needs of the procedure.
