Clinical Trial
[Results and complications in the treatment of periprosthetic femur fractures with a locked plate system].
Locked plate devices offer advantages in the treatment of periprosthetic femur fractures associated with fixed total hip or total knee arthroplasty. The purpose of this study was to evaluate the early results and complications with a locked plate system (NCB-DF(R)). ⋯ Fixation of periprosthetic femur fractures with a locked plate system provided satisfactory results in patients with a THA, however, the relatively high implant failure rate in fractures above a stable TKA is a cause for concern.

We describe the case of a 6-year-old girl with post-traumatic torticollis after falling on her head. The suspected fractures of the dens axis and/or atlas were ruled out after performing CT and MRI examinations as well as dynamic fluoroscopy. Radiological findings showed no further instability but there was a congenital non-fusion of the posterior arch and an age-appropriate non-fused anterior arch of the atlas. In addition to discoligamental injuries and fractures, congenital anomalies and normal variants of the immature anatomy of the cervical spine should also be considered in the diagnosis of the pediatric cervical spine after trauma.

Proximal humeral fractures are common in the elderly population and are often associated with osteoporosis. Fixation of unstable proximal humeral fractures is problematic due to loss of fixation in osteoporotic bone. Fixed-angle devices are intended to provide superior mechanical stability due to the principle of an internal fixator. The NCB(R)-PH (non-contact-bridging proximal humerus) plate is a new fixed-angle device that locks the screws to the plate by secondary insertion of a locking cap. The aim of this study was to investigate if and to what extent NCB-PH plates applied in the locked mode provide higher mechanical stability in a proximal humerus fracture model. ⋯ The NCB-PH plate provides superior interfragmentary stability when used in the locked mode in a human cadaveric proximal humerus fracture model. Therefore, we recommend that all screws should be inserted in the locked mode. The results suggest that the NCB-PH plate in the locked mode provides higher primary postoperative stability thus permitting early functional treatment of the patient.

Since 1992 the German Bundeswehr has been deployed for securing peace and peacekeeping abroad. Since then 83 German soldiers have been killed and overall 129 wounded in action as of 07.12.2009. In Northern Afghanistan the German Bundeswehr runs a combat support hospital (role 3) in Mazar-e-Sharif providing a multidisciplinary capability profile. ⋯ The German Navy also has two equivalent role 2 medical treatment facilities (Naval Rescue Centers) aboard its two combat support ships (CSS) "Berlin" and "Frankfurt am Main" to support maritime task groups operating worldwide. These floating field hospitals provide an indispensable asset in the medical emergency care of naval operations with difficult space-time factors. Due to the specific operating alliance between CSS and Naval Rescue Center, special operations as well as evacuation and humanitarian missions following disasters near the coastline can be effectively accomplished.
