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.

Review Multicenter Study
[Acute treatment of pregnant women after severe trauma-a retrospective multicenter analysis].
For the medical team, the management of pregnant trauma patients is a particular challenge. The aim of this study is to compile this data and to determine differences between pregnant and not pregnant trauma patients. ⋯ For the first time there is data regarding incidence, trauma mechanism, prehospital and in-hospital care as well as intensive care of pregnant trauma patients in Germany, Austria and Switzerland. Further research regarding foetal outcome and trauma-related injuries in pregnant women is needed to develop an adjusted management for these patients ready to implement in trauma centres. Gynaecologists and obstetricians should be implemented in the trauma room team when needed.

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.

Severely injured pregnant women are rarely encountered even in major trauma centers; at the same time high expectations are set for the best possible outcome of mother and child. ⋯ Teamwork, structured decision making as well as airway management and goal-oriented hemodynamic treatment are the foundations for a good outcome of mother and child.
