JOURNAL OF BRACHIAL PLEXUS AND 11 PERIPHERAL NERVE INJURY RESEARCH ARTICLE Open Access Prevalence of accessory deep peroneal nerve in referred patients to an electrodiagnostic medicine clinic 1 2 1 1 Seyed Mansoor Rayegani Elham Daneshtalab Mohamad Hasan Bahrami Dariush Eliaspour Seyed Ahmad Raeissadat 1 Sajjad Rezaei1 and Marzieh Babaee1 Abstract Background Accessory Deep Peroneal Nerve ADPN is an anatomic variation that can potentially cause disturbance in electrodiagnostic studies. This anomaly could be detected by nerve conduction studies. There are no recent updates about prevalence of this anatomic variation. Electrodiagnostic medicine clinic is the best environment for detecting presence and prevalence of this nerve so present study enrolled. Materials Methods In this cross sectional descriptive study that take place from March 2009 to July 2010 230 cases comprising 460 legs referred for electrodiagnostic studies of upper limbs problems participated in the study. Compound muscle action potential CMAP and Nerve conduction Velocity NCV of Deep Peroneal Nerve DPN were measured by using EMG machine by stimulating DPN at knee ankle and lateral malleolous areas accordingly with recording from extensor digitorum brevis muscle. Results were analyzed and conclusion made. Results The study population included 120 females 52 and 110 47 males with mean age of years. ADPN was detected in 28 patients 12 . Among them 10 had bilateral ADPN and in remained 18 cases APN was unilateral. In 8 patients there was no recorded CMAP from EDB by proximal and distal stimulation implying EDB agenesis. Gender distribution was similar which means half of the cases 14 patients belonged to each gender. Conclusion The prevalence of ADPN in this study was bilateral and unilateral . Introduction Accessory Deep Peroneal Nerve ADPN is an anatomic
