In 2020 a total of 126 patients attended the practice with distortion trauma of the ankle. Based on a thorough clinical and ultrasound examination 25 ligamentous injuries of the anterior talofibular ligament (ATFL, 9.8%), 8 osseous ligament avulsions (6.3%), 7 injuries of the lateral calcaneocuboid ligament (CC ligament, 5.6%), 5 lesions of the calcaneofibular ligament (CFL) each combined with ATFL injuries (3.9%) and 1 syndesmosis injury (0.6%) were recorded. This didactic article presents a comprehensible ultrasound examination course in an instructive manner from the clinical practice. ⋯ The talofibular advance can be measured on the monitor. Instability of the anterior syndesmosis can be visually demonstrated on the monitor using the sonographic Frick test. A final ultrasound control on the monitor confirms the structural healing and the re-establishment of ligamentous stability.

Non-union represents a severe complication and a major socioeconomic challenge in orthopedics and trauma surgery. Timely and reliable diagnostics are obligatory to be able to carry out the treatment of non-unions in a patient-specific and efficient manner. ⋯ It can display the microperfusion inside the non-union gap in real time and provide valuable information for exclusion of an infection or on the healing progress after revision surgery. An establishment of this diagnostic modality in routine orthopedic trauma surgery contributes to optimization of the treatment of non-unions.

In many cases the treatment of humeral shaft fractures is challenging and despite the large diversity of available approaches, no standard treatment exists. In addition to conservative treatment, intramedullary nails and plate osteosynthesis are competing methods for healing humeral shaft fractures. Furthermore, cerclage is considered to be an additive treatment for spiral fractures; however, this also increases the risk of radial nerve neuropathy and is said to compromise the perfusion of bone fragments. The goal of this study was to investigate secondary radial nerve neuropathy using additive and limited invasive cerclages for nail osteosynthesis of humeral shaft fractures. ⋯ Of the patients four (3.9%) showed a secondary radial neuropathy during operative stabilization. Neurophysiological and neurosonographic examinations revealed that this had not been caused by compromising, embedding or severance of the radial nerve due to the cerclage. Two out of these nerve lesions recovered spontaneously within 3 and 6 months, respectively. The other two cases could not be documented over a period of 12 months due to death of the patient. With 3.9% of iatrogenic radial nerve lesions the rate of nerve lesions falls into the lower range of that which has previously been described in the literature for nerve lesions due to operative treatment of humeral shaft fractures (3-12%). We thus conclude that there is no increased risk for iatrogenic injury of the radial nerve using additive and limited invasive cerclage.

Observational Study
[Teamwork and stress in routine interventions: an observational study of multiprofessional OR teams].
Effective interprofessional teamwork and stress are important factors for quality of care and patient safety in the operating room (OR); however, there are just a few systematic investigations into the relationship of OR teamwork and occupational stress. ⋯ The findings suggest a profession-specific relationship between OR teamwork and occupational stress. Further research is necessary to investigate to what extent successful OR teamwork during routine procedures contributes to intraoperative stress.
