Unusual variation in musculocutaneous nerves in Nepalese.

BACKGROUND

Variations in origin, course, branching pattern, termination and connections of the musculocutaneous nerve in the arm are not as uncommon as was once thought. Variational study of nerve in Nepalese is very less and can be of surgical-clinical importance. This opinion led us to performing this study.

OBJECTIVES

The aim of this study was to a study in Nepalese which could be important for clinical investigation and the surgical treatment of peripheral nerve injury.

MATERIALS AND

METHODS

This study was carried out in Manipal College of medical sciences (MCOMS). Dissection of formalised 16 cadavers (n=32 upper limbs) were carried out using normal dissection kit with the help of standard dissection manual in two and half years.

RESULTS

The study revealed the variation in course, branching pattern and termination of musculocutaneous nerve in 6.25% of cases unilaterally on the right side. No statistically significant differences by gender and side were observed.

CONCLUSION

This present study provides the evidence of variation of musculocutaneous nerve in Nepalese. The knowledge of the anatomical variations of the peripheral nerve system can help explain an incomprehensible clinical sign.
