Neurovascular injuries in fractures threaten at least the function of extremities. The timely interaction between diagnosis and treatment of vascular injuries helps to avoid a poor outcome or even fatal complications. An important parameter is to "think about it" for injuries under strain. ⋯ The debate about the sequence of repair (vascular vs. osseous) has to be decided on an individual basis; however, when in doubt vascular repair should be given priority. Vessel reconstructions should be performed without tension and must be covered by vital soft tissues, the indications for fasciotomy should be liberally interpreted. The prognosis with respect to preservation of the extremity and long-term functional outcome substantially depends on the quality of treatment of accompanying injuries.

The aim of this study was the elaboration of clinical symptoms and image findings in injuries of the wrist and ulnar-sided pain with accompanying damage to the articular disc and the triangular fibrocartilage complex (TFCC). ⋯ In cases of injuries of the wrist and ulnar-sided pain collateral damage to the articular disc and the TFCC should always be considered and excluded when appropriate. A dislocation of the disc at the wrist is a rare consequence of trauma but should be considered in the differential diagnosis. In cases of unclear MRI results and complex injuries of the wrist or unclear symptoms, MR arthrography can be helpful.

The 3D printing technology enables precise fracture models to be generated from volumetric digital imaging and communications in medicine (DICOM) computed tomography (CT) data. Apart from patient treatment, in the future this technology could potentially play a significant role in education and training in the field of orthopedic and trauma surgery. Preliminary results show that the understanding and classification of fractures can be improved when teaching medical students. ⋯ Especially for complex articular fractures, such as those of the acetabulum and tibial plateau, initial evidence shows patient benefits in terms of reduced surgery time and blood loss with the help of 3D models. The use of 3D printing on-site at the hospital is of particular interest in orthopedic and trauma surgery as it promises to provide products within a short time. The low investment and running costs and the increasing availability of convenient software solutions will spur increasing dissemination of this technology in the coming years.
