[Nerve injuries and posttraumatic therapy].

Peripheral nerve injuries are a common clinical problem and can represent a major challenge, especially after trauma. In order to achieve optimal therapy, an early and adequate diagnosis with subsequent therapy is critical for functional preservation and restoration. Especially after complete severance of a peripheral nerve, the surgical techniques for nerve coaptation are an important prerequisite for peripheral nerve regeneration. The importance and necessity of adequate nerve coaptation and nerve transplantation are presented in detail. In addition, the types of primary and secondary nerve reconstruction procedures are described as well as the optimal time point of nerve repair. This article provides a comprehensive overview of the possibilities for diagnosis and intervention after nerve injury, additionally including an algorithm for surgical intervention. Furthermore, possible pitfalls and factors for improving the functional outcome are presented to optimize results with trauma-related nerve injury.
