Controlled Clinical Trial
[Fixed angle carbon fiber reinforced polymer composite plate for treatment of distal radius fractures : Pilot study on clinical applications].
The clinical implementation of a new carbon-fiber-reinforced polyetheretherketon (PEEK) plate for distal radius fractures might offer advantageous properties over the conventional metallic devices. This includes similar elastic modulus to cortical bone, radiolucency, low artifacts on MRI scans and the lack of metal allergies. ⋯ First experience with PEEK plate osteosynthesis demonstrate quick clinical implementation with good clinical outcome and the advantage of excellent postoperative radiological assessment. At early follow-up PEEK even showed a trend for improved functional results.

An implant used for stabilizing a fracture creates a mechanical construct, which directly determines the biology of bone healing. The stabilization of fractures places high mechanical demands on implants and therefore steel and titanium are currently almost exclusively used as the materials of choice. ⋯ An essential prerequisite for the secondary fracture healing is an appropriate mechanobiological environment, which can be controlled by the osteosynthesis material and the configuration and is also affected by the type of fracture and load.

One representative case of burns caused by the negligent use of bioethanol, which was treated at our burns centre is used to illustrate the severity and depth of the burn injuries as well as the complexity of the further long-term course of treatment including complex secondary-reconstructive techniques.

Case Reports
[Atypical subtrochanteric femur fracture under alendronate therapy in spite of an intramedullar implant].
There are a number of case reports about women undergoing long-term bisphosphonate therapy who have suffered an atypical subtrochanteric or femoral shaft fracture due to an inadequate trauma. The present case reports on a patient who underwent a subtrochanteric femur fracture with the inserted AO femur interlocking nail.

Review Meta Analysis Comparative Study
[Susceptibility to infections and behavior of stainless steel : Comparison with titanium implants in traumatology].
Despite modern treatment options, implant-associated infections (IAI) remain a severe and challenging complication in the treatment of trauma patients. Almost 30 years after the introduction of implants made of titanium alloy into the treatment of trauma patients, there is still no uniform consensus regarding the clinical benefit of titanium alloy in the context of patients with IAI. ⋯ Considerable debate remains concerning the influence of the implant material on the susceptibility to IAI; however, the available literature shows that despite slight tendencies, there is no proof of titanium alloy being favorable in the susceptibility to IAI. Furthermore, the literature shows that the design of plates for osteosynthesis might influence IAI. In particular, plates that cause less soft tissue damage and preserve perfusion of the periosteum proved to be beneficial regarding IAI.
