What is osseointegration?

Osseointegration is a term founded by Professor Per-Ingvar Brånemark after his important breakthrough in the 1950s when he discovered that bone can integrate with titanium components.

Professor Brånemark named his discovery from the Latin word os – which means bone, and integrate – which means make whole, which can also be expressed as interactive coexistence.

A titanium screw-shaped implant fixture is carefully placed in the bone and amazingly enough the genetic code that commonly makes bone reject a foreign material is not activated. Instead nature allows bone cells to attach to the titanium surface and the result is a firm and permanent anchorage for a prosthetic reconstruction.

Why OPRA Surgical System?

Over 20 years of clinical development and experience

Experience - The first OPRA patient was treated in Sweden in 1990. The first Australasian symposium on Osseointegration took place in Melbourne in April 1994. The first Australian patient was treated in 1995. Over 250 patients have been treated with the OPRA Surgical system world wide. OPRA utilises a collaborative team approach between surgical teams worldwide.

Benefits

The main difference between a conventional socket prosthesis and a bone anchored prosthesis is the absence of a socket, which means the prosthesis always fits, always attaches correctly and is always firmly held in place.

The absence of a socket also relieves other problems directly related to the use of a socket, such as heat, chafing and discomfort. It also eliminates pressure sores and pain.

The OPRA surgical system allows better sitting comfort, stable attachment and better quality of life.

Versatility The OPRA Surgical System is the most versatile implant system for treatment of amputees.

With OPRA Surgical System there is no stoma. The OPRA System utilises the biology of the soft tissue and bone tissue to almost create a seal for the transcutaneous abutment. This greatly reduces and almost eliminates the problems of exudate, granulating tissue and pain.

The OPRA system is applied to Femurs, Humerus, Thumbs and Digits.

World first

In collaboration with Integrum AB, Chalmers University of Technology and Gothenburg University Dr. Rickard Brånemark performed the world’s first permanent implantation of electrodes in nerves and muscles for prosthetic control.
