Kienböck's disease, also known as avascular necrosis of the lunate bone describes the slowly progressive osteonecrosis of the lunate bone with secondary development of osteoarthritis and carpal collapse. In order to emphasize the atraumatic origin of the disease, this is normally referred to as aseptic, idiopathic or avascular lunate necrosis. ⋯ New sophisticated classification methods provide the basis for a differentiated treatment. This article provides an overview of the current state of knowledge about the etiology and pathogenesis as well as the clinically relevant diagnostic procedures and classifications.

Typical lesions of the carpal ligaments are mostly found after a fall on the wrist in hyperextension or as complex injuries after severe trauma, e. g. after a fall from a significant height, motorcycle accident or as accompanying lesions in multiple trauma. The typical mechanisms, patterns and diagnostic algorithms are well known for the common ligamentous injuries (e.g. scapholunate, lunotriquetral and perilunate); therefore, consistent diagnostic procedures and adequate therapy are increasingly performed after such lesions, e. g. by early ligament repair or by ligament reconstruction through augmentation. ⋯ If followed by immobilization with a cast or stable brace, healing can be achieved in most cases; however, more problems occur if ligamentous lesions or instabilities are not clearly due to a trauma mechanism and more the result of laxity or hypermobile situations due to a congenital predisposition. In such cases, wrist pain is often described and misdiagnosed as the result of overload or tenovaginitis.

Patients with multiple injuries in particular frequently also suffer from chest trauma. During the initial phase the identification and treatment of life-threatening injuries is essential and tension pneumothorax is of particular importance during this phase. ⋯ In the further treatment especially a flail chest and retained hemothorax are responsible for complications, such as acute lung failure and thoracic empyema. Early operative interventions in the sense of rib fracture stabilization and thoracoscopy-assisted evacuation of hematomas can help to prevent such complications.

In acute medical care, there are patients who have been injured by the influence of others. The aim of this study was to analyze all cases which were presented to the Institute for Legal Medicine of the University Halle (Saale). The cases where analyzed in relation to the victims' statistics of the state office of criminal investigation in Saxony-Anhalt. ⋯ There were only a small number of consultations of legal medicine specialists in relation to the victims' statistics. Most of them were children and women. The temporal latency between the act of violence and the consultations was one day and more. The latency and the renunciation of the consultation of the legal medicine specialists can lead to loss of evidence.
