Osseoanchored Prosthesis for the Rehabilitation of Amputees (OPRA), is part of afield more broadly known as osseointegration. The OPRA implant is an alternative to traditional sockets in that the external prosthesis is anchored directly to the patient’s remaining bone through a permanently implanted titanium screw that comes through the skin. Therefore, the prosthesis always attaches correctly, remains firmly in place, and is free from pressure sores, pain, heat, chafing and general discomfort found with traditional solutions. Built upon the discovery that bone can integrate with titanium components, the technology has been used to anchor dental implants, helping millions of patients worldwide.
