Abstract:
Meralgia paresthetica is often idiopathic, but sometimes symptoms may be caused by traumatic injury to the lateral femoral cutaneous nerve (LFCN) or compression of this nerve by a mass lesion. In this article the literature is reviewed on unusual causes for meralgia paresthetica, including different types of traumatic injury and compression of the LFCN by mass lesions. In addition, the experience from our center with the surgical treatment of unusual causes of meralgia paresthetica is presented. A PubMed search was performed on unusual causes for meralgia paresthetica. Specific attention was paid to factors that may have predisposed to LFCN injury and clues that may have pointed at a mass lesion. Moreover, our own database on all surgically treated cases of meralgia paresthetica between April 2014 and September 2022 was reviewed to identify unusual causes for meralgia paresthetica. A total of 66 articles was identified that reported results on unusual causes for meralgia paresthetica: 37 on traumatic injuries of the LFCN and 29 on compression of the LFCN by mass lesions. Most frequent cause of traumatic injury in the literature was iatrogenic, including different procedures around the anterior superior iliac spine, intra-abdominal procedures and positioning for surgery. In our own surgical database of 187 cases, there were 14 cases of traumatic LFCN injury and 4 cases in which symptoms were related to a mass lesion. It is important to consider traumatic causes or compression by a mass lesion in patients that present with meralgia paresthetica.
摘要:
感觉异常午痛通常是特发性的,但有时症状可能是由于股外侧皮神经(LFCN)的创伤性损伤或肿块性病变压迫该神经引起的。在这篇文章中,文献回顾了美感异常的异常原因,包括不同类型的创伤性损伤和肿块性病变对LFCN的压迫。此外,介绍了我们中心对异常疼痛的手术治疗的经验。PubMed对异常疼痛的异常原因进行了搜索。特别注意了可能导致LFCN损伤的因素以及可能指向肿块病变的线索。此外,我们对2014年4月至2022年9月期间所有手术治疗的感觉异常疼痛病例的数据库进行了审查,以确定感觉异常疼痛的异常原因.总共确定了66篇文章,报道了异常疼痛感觉异常原因的结果:37篇关于LFCN的创伤性损伤,29篇关于LFCN被肿块性病变压迫。文献中最常见的外伤原因是医源性,包括髂前上棘周围的不同手术,腹内手术和手术定位。在我们自己的187例手术数据库中,外伤性LFCN损伤14例,症状与肿块病变有关4例。重要的是要考虑创伤原因或肿块性病变对存在感觉异常的患者的压迫。
