Anatomical Variations in Formation of Sural Nerve in Adult Indian Cadavers
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 sural nerve is universally recognized by s...

| Summary: | 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 sural nerve is universally recognized by surgeons
as a site for harvesting an autologous nerve graft and for nerve
biopsies in case of neuropathies.
Setting and Design: Anatomy department and an observational
study.
Statistical Analysis: The Mean, Standard Deviation, relevant
percentages and p value was calculated by Chi–square test.
Material and Methods: The study consists of 50 lower limb
specimens in 25 cadavers. All the male and female complete
cadavers were included in the study. The data was collected
by dissection method by using dissection instruments and
parameters (measurements) were obtained by using measuring
tape.
Results: The sural nerve complex was dissected and observed
in 50 formalin fixed lower limb specimens. Study was done in 16
male and 9 female cadavers. Three types of formation of sural
nerve were observed were - Type A was seen in 36 specimens
(72%) of cases. Type B was seen in 14 specimens (28%) of
cases. Type C sural nerve was not found in present study. Site
of union of components of SN was seen in the upper 3rd of leg
in 5.6%, in middle 3rd it was in 33.3% and in lower 3rd it was in
58.3% of cases. The length of the sural nerve shows a wide
range from 2 cm to 32 cm. The symmetrical distribution was
seen in 62.5% in males and 55.6% in female.
Conclusion: The normal anatomy and variations may help to
guide during surgeries in the region. |
