[Preformed plate-fixation system for type AO 13C3 distal humerus fractures: clinical experiences and treatment results taking access into account].

In distal intraarticular humerus fractures primary stable osteosynthesis is essential for early mobilization of the elbow joint. Double-plate osteosynthesis techniques using different configurations are the gold standard. In the literature plate position is sometimes discussed controversially.

[Proximal femoral fractures in the elderly. Analysis of data from health insurance providers on more than 23 million insured persons--part 1].

Background: The section of geriatric trauma ("AG-Alterstraumatologie") of the "Deutsche Gesellschaft für Unfallchirurgie" (DGU) and the "Lohmann & Birkner Health Care Consulting GmbH" in co-operation with the health insurance funds (VdAK and AEV) supplied the relevant data of approximately 23 million insured persons from the years 2002 to 2004.

Methods: All data from patients over the age of 60 staying in hospital because of proximal femur fractures and without further injuries as the main diagnosis were extracted from the available amount of data and then analysed. There were 68,929 (9.

All data from patients over the age of 60 staying in hospital because of proximal femur fractures and without further injuries as the main diagnosis were extracted from the available amount of data and then analysed.

Results: In comparison to the effective number of beds there was a significant increase in the treatment of proximal femur fractures in hospitals with 101-300 beds.

[Is use of the fixateur externe no longer indicated for the treatment of unstable radial fracture in the elderly?].

Background: In recent years there has been an increasingly marked shift in the operative treatment of unstable fractures of the distal radius. The introduction of locking compression plates has made it possible to extend the indications for palmar stabilisation according to the principles of internal fixation to extension fractures even in osteoporotic bone, and since then the new design has been used more and more widely. First clinical results show very good and good clinical and radiological outcomes in over 80% of cases after locking compression plate osteosynthesis.

Rinsing-suction reamer attenuates intramedullary pressure increase and fat intravasation in a sheep model.

Background: Reamed intramedullary nailing causes an increase of intramedullary pressure. A new rinsing-suction reamer (RSR) can reduce this problem, and it was evaluated in animal experiments in comparison with the AO reamer (AOR) to see its effects on intramedullary pressure and fat intravasation.

Methods: Reamed intramedullary nailing was performed in 14 sheep using the RSR or AOR.
