Osseointegrated prostheses for rehabilitation following amputation : The pioneering Swedish model.
The direct attachment of osseointegrated (OI) prostheses to the skeleton avoids the inherent problems of socket suspension. It also provides physiological weight bearing, improved range of motion in the proximal joint, as well as osseoperceptive sensory feedback, enabling better control of the artificial limbs by amputees. The present article briefly reviews the pioneering efforts on extremity osseointegration surgeries in Sweden and the development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) program. ⋯ The results of long-term follow-up for transradial, transhumeral, and thumb amputee operations are briefly reported including the prospective study of transfemoral amputees according to OPRA protocol. The importance of refinement on implant designs and surgical techniques based on the biomechanical analysis and early clinical trials is emphasized. Future aspects on osseointegration surgery are briefly described, including novel treatment options using implanted electrodes.

There is an ongoing discussion about demographic change, a possible lack of young doctors and its impact on the healthcare system in Germany. Up to now, no valid data has been available on the exact numbers of residents in orthopedics and trauma surgery. Therefore, the aim of this study was to determine the actual number of residents in Germany in 2013/2014. ⋯ Looking at the expected number of doctors who will retire within the next five years, there seems to be enough young doctors to fill the gap. However, by 2040, an increased demand for othopedic and trauma surgeons is experted. Thus, we recommend centrally analyzing and coordinating the demand of residents in orthopedics and trauma surgery in Germany.

In the treatment of complex pelvic fractures hemorrhage control is of primary importance; however, studies regarding the localization of bleeding are contradictory so that various treatment approaches are recommended. The primary aim of external pelvic compression applied in the trauma room is to reduce the pelvic volume and counteract blood loss through self-induced tamponade. This study examined the influence of external pelvic compression on mortality and outcome in cases of hemodynamically unstable pelvic fractures in a larger number of cases. ⋯ External pelvic stabilization seems to be an important instrument for the initial treatment of hemodynamically unstable pelvic fractures and showed a positive effect on patient mortality.

Nerve entrapment syndromes in the upper extremities are common clinical disease patterns, less often as direct results of accidents. The most frequent compression syndrome is the carpal tunnel syndrome followed by the cubital tunnel syndrome. If the cause of the compression cannot be eliminated by conservative treatment options, an operative therapy is necessary. As the prognosis becomes worse with the duration of the nerve compression, it is important to initiate therapy at an early stage.

As part of the expansion of the site-specific education profile of the medical curriculum MED@ULM of the University of Ulm, a new track "trauma care and trauma research" was established in the winter semester 2012/2013. The acceptance of the track was evaluated during the winter semester 2013/2014. ⋯ With the introduction of the new trauma track into the curriculum of the medical curriculum MED@ULM of the University of Ulm, a further possibility for medical students to focus on their own individual options was established. At least half of the track students wanted to be later active in the triad of patient care, teaching and research. Further investigations are necessary to determine whether the establishment of the trauma track has a positive influence on the number of new recruits in trauma surgery and anesthesiology.
