Due to the frequency and potentially complicated course distortion of the upper angle joint represents an important entity in the orthopedic patient clientele. The initial diagnosis includes a detailed anamnesis of the injury mechanism and an accurate clinical examination. To exclude bony, ligamentous and chondral lesions, besides basic diagnostics consisting of X‑rays and ultrasound, magnetic resonance imaging (MRI) is considered the most important tool. ⋯ If conservative therapy fails and thus chronic instability develops the indications for operative treatment are given. Meanwhile, surgical techniques have been established with satisfactory results. Inadequate rehabilitation could be identified as a major risk factor for re-injury, therefore phase-adapted aftercare has gained significant importance.

Injuries to the distal tibiofibular syndesmosis are frequent and continue to generate controversy due to an extensive range of diagnostic techniques and therapeutic options. ⋯ The single most important prognostic factor after unstable injury of the distal tibiofibular syndesmosis with or without fracture is the anatomic reduction of the distal fibula and fitting into the tibial incisura.

Rat bite fever due to Streptobacillus moniliformis induces typical but not pathognomonic clinical signs, such as local purulent wound infection followed by maculopapular exanthema, myalgia as well as purulent joint infections. Severe complications, such as osteomyelitis and endocarditis are possible. it seems that this infection is rarely diagnosed but this infection could be much more common because the final diagnostic proof is difficult to achieve. ⋯ Surgical cleansing of infection sites in combination with a rational antibiotic therapy, for example with beta-lactam antibiotics, are generally able to cure the infection if treatment is started early enough. In addition, vaccinations, for example against tetanus and rabies have to be considered in this situation as for all other bite wound infections.

Vertebral body fractures (VBF) can be caused by various trauma mechanisms. The AOSpine classification system differentiates three main types of fractures according to the grade of instability. How the increasing energy of various accident mechanisms changes the complexity of the individual fracture, its localization and the occurrence of further fractures has not yet been finally investigated. ⋯ An exact reproduction of the traumatic event enables a distinction between high and low energy trauma groups to be made. In previous studies traffic accidents were recorded as one group, so an influence of the increasing kinematic energy could not be assessed. The accident kinematics can be taken into account by differentiating between high and low-energy trauma groups. In high-energy accidents the TH7 and TH10 vertebrae were found to be at risk vertebrae. In addition to the force direction, the force strength also has a decisive influence on the distribution pattern of VBF.
