Meralgia paraesthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN), typically caused by compression at the level of the inguinal ligament. The syndrome presents with burning pain, paraesthesia, and hypaesthesia in the anterolateral thigh, without motor deficits. The LFCN, derived from the L2–L3 spinal nerves, is vulnerable to compression or traction due to its anatomical course under the inguinal ligament. MP may result from both traumatic (e.g., surgery, injury) and non-traumatic causes (e.g., obesity, pregnancy, tight clothing). In some cases, the etiology remains unknown. Diagnosis is primarily clinical and based on patient history and physical examination. Imaging techniques and electroneurography can support diagnostic confirmation in unclear cases. If symptoms extend beyond the typical LFCN territory, are bilateral, or are accompanied by motor or reflex abnormalities, differential diagnoses – including radiculopathy, involvement of adjacent nerves, or anatomical variations of the" /> Bei brennenden, einschießenden Schmerzen oder Hypästhesien an der Oberschenkelvorderseite sollte differenzialdiagnostisch auch an eine Meralgia paraesthetica gedacht werden. Diese Kompressionsneuropathie des N. cutaneus femoris lateralis wird differenzialdiagnostisch mitunter nicht berücksichtigt, lässt sich jedoch in der Regel klinisch diagnostizieren. Das therapeutische Spektrum reicht von konservativen Maßnahmen bis zur operativen Dekompression.
