Osseointegrated prostheses for the rehabilitation of amputees (OPRA): results and clinical perspective.

Introduction : Patients who undergo extremity amputation have historically used socket prosthetics to ambulate and perform daily functions; however, these prosthetics can be limited by poor terminal control and wear issues. In patients who have difficulty wearing their prostheses or with upper extremity amputations, osseointegrated implants may offer better function and quality of life. The Osseointegrated Prostheses for the Rehabilitation of Amputees (OPRA) was the first such device to become commercially available. Clinical trials have demonstrated benefit in patient gait, prosthetic use, and overall well-being, and new implants may be applied for various amputation levels. Areas covered : The OPRA, the most studied osseointegrated prosthetic stem, is reviewed, presenting indications, surgical procedure, complications, and results of clinical studies. Expert commentary : Osseointegration for amputees is an expanding field that has the potential to enhance rehabilitative potential. The OPRA implant is an effective device with a long life-span and low complication profile.
