The results of a national survey from 1998 showed that only around 10 % of orthopaedic surgeons in Germany had strictly implemented modern third-generation cementing techniques in total hip arthroplasty (THA). A 2005 update showed an improvement up to 29.4 %. The study was repeated in 2010 in order to evaluate the current situation and to determine whether modern cementing techniques have become more popular. ⋯ The results of this survey demonstrate that, in comparison to 2005, the current state of cemented THA, in particular cementing technique has generally significantly improved. Future emphasis should focus on continued surgeon education and training, as the cementing techniques are of utmost importance for long-term durability.

Due to the aging population, we are confronted with a growing number of osteoporotic and insufficiency fractures of the pelvic ring. They are the result of a low-energy trauma. With conventional X-rays, it is not always possible to identify the lesions. ⋯ The choice of treatment is determined by the degree and the localization of the instability. Osteosynthesis techniques differ from the techniques we use in adults. The trans-sacral positioning bar, iliolumbar fixation and angle stable plate osteosynthesis are used increasingly often.

For the clinical planning of mass events the emergency departments are of critical importance, but there are still no data available for the workload in these cases. As this is essential for an effective medical preparation, we calculated the workload based on the ICD codes of the vicitims at the Loveparade 2010 in Duisburg. ⋯ The calculation of workload from the ICD data is a reasonable tool for retrospective estimation of the workload of an emergency department, the data can be used for future planning. The retrospective MTS grouping is at present not suitable for a realistic calculation. Retrospective measures in the MTS groups are at present not sufficiently suitable for valid data publication.

Comparative Study Controlled Clinical Trial
[Operative treatment of proximal humeral four-part fractures in elderly patients: comparison of two angular-stable implant systems].
Although being one of the most common fractures in elderly patients, there is still no standardised treatment protocol for four-part fractures of the proximal humerus. However, a wide variety of angular-stable implants is available. The present retrospective study compares the clinical and radiological outcome following operative treatment of four-part fractures of the proximal humerus with the Philos system (Philos, proximal humeral internal locking system, Synthes GmbH, Umkirch Germany) and the angular-stable Königsee plate system (Königsee Implantate GmbH, Allendorf, Germany) in patients older than 65 years. ⋯ In this study we were able to demonstrate that good and satisfactory results can be achieved in the majority of patients, regardless of whether a Philos or a Königsee system was used. Significant differences between the two groups could not be found in any of the performed examinations. Both implants seem to be suitable in four-part fractures of the proximal humerus. However, the Königsee plate represents a more cost-effective option compared to the Philos system.
