Observational Study
[The Berlin mass casualty hospital triage algorithm : Development, implementation and influence on exercise-based triage results].
Patient triage has a key function within the scope of the successful management of mass disasters and ensures the correct resource allocation. Analysis of unheralded hospital disaster training in Berlin hospitals revealed triage problems referring the correct classification of patients in the triage categories and relevant overtriaging and undertriaging. Therefore, a triage algorithm tailored to the clinical setting was developed in Berlin and after presentation and discussion within the circle of the representatives for clinical catastrophe protection, the algorithm was introduced as obligatory in 2015. This study was carried out to validate and investigate the effects of the triage algorithm. ⋯ The Berlin hospital triage algorithm was successfully validated. The triage category allocation was significantly improved in all relevant aspects after implementation with a significant reduction of overtriaging and undertriaging.

Lesions of peripheral nerves substantially influence the long-term prognosis and functional outcome. Approximately 70% of peripheral nerval lesions are associated with vascular injuries and occur more frequently with certain fractures and osteosynthesis types. The prognosis and treatment depend on the severity of the injury and the presence of axonal lesions, in particular, determines the further procedure. ⋯ Iatrogenic vascular lesions occur particularly in percutaneous interventions and are reported in up to 8% of cases after operations involving the musculoskeletal system. Iatrogenic nerve lesions are almost exclusively the result of surgical procedures and represent up to 17.5% of traumatic nerve injuries. For all lesions the general principles of surgical treatment are valid and the rapid involvement of professional expertise is decisive.

The treatment of flexor tendon injuries is still challenging, especially in the region of the narrow annular ligaments and tendon sheaths of the 3‑segment fingers and the thumb (zone 2). In the course of time, the primary suture of the flexor tendons has prevailed over traditional recommendations for a secondary tendon replacement after healing of the wound. Improvements regarding suture techniques and materials and, above all the follow-up treatment, have been crucial for better results and remarkable changes in flexor tendon surgery. ⋯ To achieve this an early functionally active protocol should be implemented. The tendon suture should enable this by having a high primary strength and therefore at least a 4-strand core suture technique with a ring suture should be given preference. Further important prerequisites for success are the undisturbed gliding of the repaired tendon in its "bed" paying special attention to the annular ligaments and preservation of the blood supply to the tendons.

The current boom in recreational sports leads to an increase in the number of long-distance runners. In addition to typical disease patterns (e.g. of the Achilles tendon) stress fractures are seen more and more frequently. ⋯ Atypical and protracted complaints therefore require a detailed medical history of the patient and should if in any doubt lead to radiological imaging. Once correctly diagnosed, rest from sports and sometimes semi-weightbearing or non-weightbearing is indicated to prevent the development of fracture non-union.
