Objective: Peroneal neuropathy is the most common entrapmentmononeuropathy in the lower extremity. The common site of injuryis around the fibular head where the nerve becomes superficial.Compressive pathologies are the most frequently seen etiologies. Thetreatment plan is designed according to the etiology. Electrophysiologicinvestigations are accepted as the gold standard for the diagnosis ofperoneal neuropathy. In this study, we aimed to evaluate the etiologicfactors and electrodiagnostic findings in peroneal neuropathy. Method: We retrospectively analyzed the etiological and electrodiagnostictest findings of patients with clinical features compatible with peronealneuropathy, who presented to the Electromyography Laboratoryof İstanbul Medipol University Hospital between January 2016 andDecember 2019. Patients with polyneuropathy or a disease that maycause polyneuropathy such as diabetes mellitus, those with lumbosacralradiculopathy or plexopathy, and those with neurodegenerative diseaseswere excluded. Results: A total of 30 patients with clinical features compatible withperoneal neuropathy (19 males, 11 females, median age 30 years; range21 to 66) were enrolled in the study. Four (13.3%) patients had a comorbiddisease. The median duration (minimum-maximum) of the symptoms was20.5 (2-140) weeks. The affected side of the peroneal nerve was 43.3%right, 43.3% left, and 13.3% bilateral. The common cause of peroneal nerveinjuries was due to compression (40%). Potential causes of compressionin five out of 12 cases were iatrogenic. Weight loss was found in 10%of patients and one patient (3.3%) had a history of a recurrent ganglioncyst. Approximately 23% of lesions were due to traction injury and 23% of cases were idiopathic. According to electrophysiologic investigations,16 cases were predominantly demyelinating without axonal injury. Theaxonal injury was detected in the remaining 14 cases (%46.6) and half ofthe cases with axonal injury were accompanied by demyelinating injury.Six cases had mild, 3 cases had severe, and 5 cases had a total axonalinjury.Conclusion: Compression is the most commonly seen etiologicalfactor in peroneal neuropathy. Electrophysiologic investigations play asignificant role in the differential diagnosis, prognosis, management plan,and follow-up of recovery. Further detailed studies are needed to clarifythe relationship between electrophysiologic findings and prognosis toform an algorithm for the treatment and follow-up.
