TI  - Distribution of sympathetic fiber areas in the sensory nerves of forearm: an 
      immunohistochemical study in cadavers.
PG  - 605-11
AB  - PURPOSE: Secondary to peripheral nerve injuries, involvement of sympathetic 
      fibers complications such as Complex Regional Pain Syndrome (CRPS) have been 
      reported. There are no reports available in the distribution of the sympathetic 
      fibers/areas of sensory nerves in the forearm. MATERIALS AND METHODS: The present 
      study aim is an attempt to find the distribution of sympathetic fibers in the 
      anterior branch of medial antebrachial cutaneous nerve of forearm (AMACN), 
      lateral antebrachial cutaneous nerve of forearm (LACN) and superficial branch of 
      radial nerve (SBRN) at cubital fossae. We have studied on 17 fresh human 
      cadaveric AMACN, LACN and SRBN samples. Frozen sections of these nerves were 
      processed by immunohistochemical (tyrosine hydroxylase) method for sympathetic 
      fibers. RESULTS: Sympathetic fibers area (Asym) was found to be more in SBRN when 
      compared to AMACN and LACN. The comparison of the sympathetic index (SI = 
      sympathetic fibers area / total fascicular area of the nerve) between AMACN and 
      LACN (p-value < 0.001), AMACN and SBRN (p-value <0.001), LACN and SBRN (p-value < 
      0.001) were statistically significant. Sympathetic index (SI) for SBRN was more 
      when compared to AMACN and LACN. SBRN had maximum percentage (5.16%) of Asym when 
      compared with LACN and AMACN. CONCLUSIONS: Sympathetic fibers area (Asym), 
      sympathetic index (SI) and percentage of sympathetic fibers area (Asym %) were 
      found to be more in SBRN when compared with AMACN and LACN. These results of the 
      study might help to explain sympathetic system-related diseases in the area of 
      distribution of AMACN, LACN and SBRN.
