Risk Analysis of Restrictive Factors for Fast-Track Knee Arthroplasty-A Retrospective Study of 1,224 Patients.

Introduction: With the implementation of a fast-track principle as an interdisciplinary and multimodal concept, an accelerated convalescence and reduction of postoperative complications and a reduction of hospital stay can be achieved. This has been shown not only to increase patient satisfaction but in reduction of hospital cost as well. However, the concept cannot be successfully implemented in all patients.

Treatment management and outcome of polytraumatized patients in a German certified trauma center - comparing standard versus maximum care.

German hospitals are classified as basic, standard and maximum care facilities within the German trauma networks. The Municipal Hospital Dessau was upgraded in 2015 as a maximum care provider. The aim of this study is to investigate whether a change in treatment management and outcome of polytraumatized patients has occurred afterwards.

Imaging Threshold for Assessment of the Correct Reduction in the Treatment of Unstable Syndesmotic Injuries - A Retrospective Analysis of 57 CT Scans.

Introduction: An incongruence of the distal tibiofibular joint (TFJ) after treatment of upper ankle joint injury represents a prearthrotic deformity and must be corrected. The objectives of this study were to analyze postoperative CT scans after surgical treatment of unstable syndesmotic injuries, and to determine the prevalence of syndesmotic malreduction and its contributing factors. The specific parameters of three-dimensional imaging for objective detection of malreduction should be identified as a helpful intraoperative imaging threshold.

Individual computer-assisted 3D planning for placement of auricular prosthesis anchors in combination with an implantable transcutaneous bone conduction hearing device in patients with aural atresia.

Background: The simultaneous implantation of the Bonebridge (MED-EL, Innsbruck, Austria), a semi-implantable active transcutaneous bone conduction hearing device and anchors for auricular prostheses can be challenging as both implants contain magnets and compete for the narrow space in the designated implantation area.

Material And Methods: A preoperative planning tool (virtual surgery) was used with individual 3D computer models of the skull and implants for finding optimal implant positions for both the floating mass transducer (FMT) and the anchors for the auricular prosthesis. The interaction between the magnetic prosthesis anchors and the FMT was measured by means of static magnetic forces.
