Unusual anatomical variation in formation of sural nerve

Background: Sural nerve is formed by communication of medial sural cutaneous nerve, that arise from tibial nerve in popliteal fossa and peroneal communicating nerve, a branch directly from common peroneal nerve or from lateral sural cutaneous nerve.The objective of this study was described an unusual and few reported anatomical variation in formation of sural nerve.
 Materials and Methods: The anatomical variation described was found during routine dissection performed by medical students of second semester in two maleembalbed adult cadavers of 75 and 65 years of age, respectivelyin the laboratory of Morphology of the University of Pamplona.
 Results and Discussion: In the left lower limb, both medial sural cutaneous nerve, and lateral sural cutaneous nervewere absent. The sural nerve arose directly from the tibial nerve. It’s observed a communicating branch between tibial nerve and common peroneal nerve. In the right lower limb, lateral sural cutaneous nerve was absent. The sural nerve arose directly from the common peroneal nerve.Peroneal communicating nerve was considered as absent in the two cases.Motor fiber from sural nerve to gastrocnemius muscle was observed in both lower limbs
 Conclusions:The knowledge of the sural nerve (normal anatomy and variations in origin and course) is important in evaluating of the patients, as well explaining the different clinical findings necessary for accuracy treatment.

Variation in the Mode of Origin and Level of Formation of Sural Nerve

Variations of nerve are not only of anatomic and embryological interest but also of clinical importance. Their adequate knowledge will help in increasing surgical precision and decreasing morbidity. In present study variations in mode of origin and level of formation of sural nerve was studied. The material for the present study comprised of 60 lower extremities belonging to 30 adult human cadavers obtained from Deptt. of Anatomy, GMC, Amritsar. The sural nerve was identified and its mode of origin and level of formation was studied. In present study, sural nerve was formed by union of medial sural nerve (from tibial nerve or from nerve to medial head of gastrocnemius) and lateral sural nerve (from common peroneal nerve) in 83.33% limbs. It was formed by medial sural nerve alone in 15% limbs. In 1.67% medial and lateral sural nerve were separate. The site of formation was in middle 1/3rd of leg in 20% limbs and distal 1/3rd of leg in 80% limbs.
