Abstract

Introduction: Variation of nerve is not only of anatomical and embryological interest, but also of clinical importance, as these can be etiological factors behind various pathological conditions. Likewise, their adequate knowledge will help in increasing surgical precision and decreasing morbidity. In present study level of division of tibial nerve into medial and lateral plantar nerve was studied.
Material and Methods:  The material for the present study comprised of 60 lower extremities belonging to 30 adult human cadavers obtained from Dept of Anatomy, GMC, Amritsar. Tibial nerve was dissected and the level at which it divided into medial and lateral plantar nerve was studied.
Result: Tibial nerve bifurcated into medial and lateral plantar nerve deep to flexor retinaculum in 93.33% of cases and proximal to flexor retinaculum in 6.67% of cases.
Discussion: There are various clinical conditions associated with the involvement of tibial nerve.  It is reported that an accessory flexor digitorum muscle is associated with high division of tibial nerve. Accessory flexor digitorum muscle can be one of causes of tarsal tunnel syndrome.
Anatomical studies of the tibial nerve in the distal third of the leg and at the level of the tarsal tunnel began to take more importance with the establishment and definition of compression pathology of this nerve, in its osteofibrous tunnel. In an analogy with the upper limb, this syndrome resembles carpal tunnel syndrome, also sharing decompression surgery as one of the therapeutic approaches.
Key words: Tibial Nerve, Medial Plantar Nerve, Lateral Plantar Nerve, Flexor Retinaculum, Accessory Flexor Digitorum Muscle.
