Introduction: Communications between peripheral nerves are important in the light of the fact that these are responsible for a myriad of clinical symptoms. Communication between the median nerve and ulnar nerve (Martin-Gruber anastomosis) is a frequent finding observed anatomically in 10%-30.6% subjects and physiologically in 5-40%. It may lead to exacerbated or attenuated clinical symptoms.
Aims & Objectives: To find out the incidence of Martin-Gruber anastomosis in North Indian population by cadaveric dissection.
Materials and Methods: The material comprised of 60 upper limbs belonging to 30 cadavers (M:F::28:2) which were dissected to find out incidence of Martin-Gruber anastomosis.
Results: Martin-Gruber anastomosis was encountered in 7(11.6%) limbs of the present study. It was seen more frequently unilaterally (16.6%) than bilaterally (3.3%) and only in males. Classification of limbs into various patterns and types was done. Further its ontogeny, phylogeny, genetic inheritance and clinical implications are discussed in detail.
Conclusion: To conclude, in North Indian population, the Martin-Gruber anastomosis is encountered in 11.6% limbs.
