Abstract
Secondary to peripheral nerve injuries involvement of sympathetic fibers complications such as complex regional pain syndrome CRPS have been reported There are limited studies on the sympathetic fibers and their distribution in the upper limb nerves There are no reports available in the distribution of the sympathetic fibers/areas of radial nerve in the forearm The aim of the present study was an attempt to find the distribution of sympathetic fibers in the radial nerve just above cubital fossa RN superficial branch of radial nerve at cubital fossa SBRN1 and above wrist SBRN2The sympathetic fibers area Asym was found to be more in RN when compared to SBRN1 and SBRN2 The comparison of the sympathetic index SI = sympathetic fibers area/total fascicular area of the nerve between RN and SBRN1 p 0001 RN and SBRN2 p 0001 and SBRN1 and SBRN2 p = 0016 were statistically significant The sympathetic index SI for SBRN1 was more when compared to RN and SBRN2Sympathetic fibers area Asym was found to be more in RN when compared to SBRN1 and SBRN2 The sympathetic ratio SI and percentage of sympathetic fibers area Asym was more in SBRN1 when compared to RN and SBRN2 These results of the study might help to explain sympathetic systemrelated diseases in the area of distribution of RN and SBRNThe authors thank K Ramachandra Bhat Professor of Anatomy Kasturba Medical College Manipal Karnataka India for his valuable suggestions and guidance The fund for the study was collected from Kasturba Medical College Manipal India The antibodies and chemicals used were purchased from SigmaAldrich Chemicals Private Limited Bangalore India
