[Perioperative Diagnostics of Peripheral Nerve Lesions and Compression Syndromes: Position Paper of the German-Speaking Group for Microsurgery of Peripheral Nerves and Vessels].

The treatment of peripheral nerve pathologies requires a rapid and precise diagnosis. However, the correct identification of nerve pathologies is often difficult and valuable time is lost in the process. In this position paper of the German-Speaking Group for Microsurgery of Peripheral Nerves and Vessels (DAM), we describe the current evidence for various perioperative diagnostics for the detection of traumatic peripheral nerve lesions or compression syndromes. In detail, we evaluated the importance of clinical examinations, electrophysiology, nerve ultrasound and magnetic resonance neurography. Additionally, we surveyed our members for their diagnostic approach in this regard. The statements are based on a consensus workshop on the 42nd meeting of the DAM in Graz, Austria.
