Blood flow restriction (BFR) limits arterial and venous blood flow and leads to blood pooling, which could increase exercise-induced training effects. Strength training at lower intensities (20-30% of maximum strength) in combination with BFR showed similar effects on muscle hypertrophy as training with 70% without BFR. Low-intensity cycling endurance training with BFR improves muscle hypertrophy and endurance performance and activates angiogenesis. ⋯ The BFR training leads to a stronger activation of the muscular metabolic reflex and thus to a relatively greater increase in exercise blood pressure, so that cardiovascular parameters should be controlled during BFR training. First meta-analyses with small numbers of healthy people and patients indicate the effectiveness of BFR training. Standardization or guidelines for clinical use are still lacking.

Accident insurance consultants (D-physicians) are qualified specialists with particular expertise in occupational medicine. Within the medical treatment procedure of the German Statutory Accident Insurance (DGUV), D‑physicians must make a report on the medical care after occupational accidents. This nationwide evaluation aimed to systematically measure the quality of documentation of these medical reports. Peer review is a common method to ensure process quality. ⋯ The first nationwide peer review of the DGUV proved to be a practical and valid quality assurance procedure to evaluate the medical reports of D‑physicians. The quality of the reports was in general good. The DGUV plans to repeat the peer review process taking further groups of D‑physicians into consideration.

Identification and treatment of intra-articular injuries, stabilization of the syndesmotic complex by open reduction and internal fixation (ORIF) of the posterior malleolus (PM). ⋯ It is known that relevant chondral injuries frequently occur in complex ankle fractures and that ORIF of the PM leads to stabilization of the distal tibiofibular joint. So far only few clinical results have been published regarding AORIF and ORIF of the PM; however, the majority of the studies available found significantly better results for AORIF and ORIF of the posterior malleolus compared to conventional treatment.

In the management of trauma patients in the resuscitation room many time-pressured and critical decisions must continuously be made in complex situations. Even experienced teams frequently make errors in this context. Computer-assisted decision-making systems can predict critical situations based on patient data continuously acquired online. Based on the calculated predictions these systems can suggest the next steps in managing the patient. This review summarizes the current literature on computer-assisted decision-making in the management of trauma patients. ⋯ Computer-assisted decision-making can help to improve the management of trauma patients; however, before a ubiquitous implementation a number of technological and legislative barriers have to be overcome.

The gold standard in operative treatment of end-stage ankle osteoarthritis remains controversial even now. Endoprosthetic treatment, which has undergone significant improvements in recent years competes with arthrodesis, which can achieve excellent results particularly in the arthroscopically assisted technique. Both procedures offer specific advantages and disadvantages so that the decision about indications for treatment should always be made individually, taking specific needs and the individual constellation of findings of the patient into consideration.
