Peroneal neuropathy is a recognized cause for foot drop, typically following trauma, nerve damage, immobilization, or prolonged external pressure. Recently, rapid weight loss after bariatric surgery has been recognised as a potential cause for peroneal neuropathy. This may be due to the loss of protective fat tissue near the peroneal nerve, increasing its susceptibility to compression. Although this complication may be infrequent in occurrence, its impact on mobility and quality of life calls for increased vigilance among clinicians. Here we report a case of unilateral peroneal neuropathy leading to foot drop after significant weight loss in a short period following bariatric surgery. The patient underwent a comprehensive clinical workup, including laboratory investigations and neuroimaging, all of which were normal. Diagnosis was confirmed by nerve conduction studies, which revealed left peroneal nerve entrapment at the fibular head. Management consisted of a multidisciplinary, conservative approach, including physiotherapy and orthotic support.
腓总神经病变是导致足下垂的一个公认原因，通常继发于创伤、神经损伤、制动或长期外部压迫之后。最近，减重手术后的快速体重减轻已被认为是腓总神经病变的一个潜在原因。这可能是由于腓总神经附近保护性脂肪组织的丧失，增加了其受压的易感性。尽管这种并发症可能并不常见，但其对活动能力和生活质量的影响要求临床医生提高警惕。在此，我们报告一例在减重手术后短期内体重显著减轻后导致足下垂的单侧腓总神经病变病例。患者接受了全面的临床检查，包括实验室检查和神经影像学检查，所有这些检查结果均正常。神经传导研究证实了诊断，该研究显示左侧腓总神经在腓骨头处受压。治疗包括多学科的保守方法，包括物理治疗和矫形支具支持。
