It reveals that the treatment improves function and quality of life in nine out of ten patients, and is the result of research carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital that is being presented this week at the International Society of Orthopaedic Surgery and Traumatology (SICOT) annual international conference in Gothenburg.
At a symposium today researcher Rickard Brånemark and others will be presenting some aspects of their OPRA study (Osseointegrated Prostheses for the Rehabilitation of Amputees) that began in 1999.
In the study, researchers at the Centre of Orthopaedic Osseointegration (COO) and the orthopaedic clinic at Sahlgrenska University Hospital in Mölndal treated 51 patients who had been amputated above the knee, with a two-year follow-up period. The patients were aged between 20 and 65, with 55% being male.
“The treatment improves both function and quality of life in more than nine out of ten patients,” says Brånemark, a researcher at the Sahlgrenska Academy and orthopaedic surgeon at Sahlgrenska University Hospital. “It’s important to point out that this treatment is intended for younger amputees and is not suitable for patients who have had amputations as a result of vascular disease.”
More than 2,000 leg amputations are carried out each year in Sweden. While most are on elderly patients with diabetes or impaired blood circulation, some are on younger patients. Normally a leg prosthesis is attached to the amputated stump using a socket. The new technique means that the prosthesis can easily be screwed tight to a titanium implant that is anchored to the bone and protrudes from the stump.
“Attaching prostheses directly to the bone with an implant has long been an unattainable vision, and this has been in development for more than 20 years. But we are now seeing the international breakthrough for this revolutionary treatment,” says Brånemark, one of the authors behind the study, who explains that work is now underway on treating other amputations such as fingers and arms.
The studies have been carried as a collaboration between Sahlgrenska University Hospital, the Department of Orthopaedics and Department of Biomaterials at the Sahlgrenska Academy, and the BIOMATCELL VINN Excellence Center of Biomaterials and Cell Therapy at the University of Gothenburg.OSSEOINTEGRATION

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
