ABSTRACT
The aim of the study was to demonstrate the relationship between the deep fibular nerve (DFN) and the dorsalis pedis artery (DPA) in the anterior tarsal tunnel(ATT) in order to provide useful anatomical knowledge for safe surgical approaches of the foot and ankle. 40 formalin fixed lower limbs were dissected and examined. The level of bifurcation of the DFN in ATT was noted. Relationship between the DFN and DPA was examined and recorded. The location of the DFN bifurcation was within the ATT in 34 specimens (85%) and was distal to the tunnel in 5 specimens (12.5%) and in one specimen (2.5%) there was bifurcation was observed proximal to the tunnel. Three distinct types of relationship were noted between the DFN and DPA. We believe that the detailed anatomical knowledge of the DFN, DPA and ATT will help during planning the surgical approaches of foot and ankle and help in diagnosis of clinical syndromes related with peripheral nerves of the foot.
