Trauma is one of the leading causes of mortality in pregnant women and significantly increases the likelihood of an unwanted termination of pregnancy. Particularly in severe trauma with an increased risk of significant maternal injuries, computed tomography (CT) remains the imaging modality of choice as it is comprehensively available, quick to carry out and has a high diagnostic accuracy in the detection and classification of life-threatening trauma-associated pathologies compared to other imaging techniques. Considering the radiation-associated risks, it is unlikely that a single, monophasic CT in the emergency trauma room will exceed the threshold of deterministic radiation damage; therefore, fetal malformations or fetal loss are not to be expected; however, there is a low stochastic risk for the delayed occurrence of radiation-induced cancer both for the child and the mother that can be considered small in comparison to missed or delayed diagnoses after severe trauma. ⋯ Magnetic resonance imaging (MRI) has a major role in the subacute setting and constitutes an excellent problem solver for specific questions, such as the evaluation of discoligamentous injuries of the spine. Its use is deemed acceptable at any stage of pregnancy when the required information is considered important for the management of further treatment. Due to potential teratogenic effects of MRI contrast media containing gadolinium on the fetus, including an increased likelihood of fetal loss, they should only be administered with great caution and under strictly defined indications.

The treatment of severely injured pregnant women places the highest demands on interdisciplinary cooperation in order to adequately account for maternal and fetal requirements. In the preclinical stage the mother must be optimally stabilized and treated. ⋯ In principle, all methods that are used in non-pregnant polytrauma patients should also be used without hesitation, especially in the initial routine diagnostics in order to establish the best treatment plan. The question of emergency delivery depends on the gestational age, the acute situation of the fetus and the mother as well as the risks resulting from the next therapeutic steps with respect to monitoring and intervention options in favor of the child.

If an accident results in a functional disorder that persists and permanently restricts physical and/or mental capacity, this is referred to as a disability. In private accident insurance it is the task of the medical expert to assess this disability by examining the medical findings and produce an assessment taking account of the literature and comparing against generally acknowledged guidance values. The priority dismemberment disability rating schedule initially provides loss values. ⋯ Of course, the functional perspective has been especially emphasized. A difficulty in achieving this was that the literature on arthrodesis is now almost only of historical value due to modern endoprosthetics. The knowledge gained was checked against medical experience and is expounded here.

The causes of patellofemoral instability (PFI) are complex. In accordance with the current literature a classification was developed which clearly weights all entities and derives diagnostic and therapeutic consequences. It considers patellar instability and patellar maltracking or the complete loss of patellar tracking and differentiates into 5 types. ⋯ Type 3: instability and maltracking; reasons for maltracking are a) soft tissue contracture, b) patella alta, c) pathological tibial tuberosity trochlear groove (TTTG) distance, c) valgus deformities and e) torsional deformities. Type 4: massively unstable floating patella, which is based on a high-grade trochlear dysplasia. Type 5: maltracking without instability.
