RESUMO

The author presents a study on the morphology of the Superficial Branch of the Radial Nerve (SBRN), at the distal one-third of the forearm and wrist. Anatomical dissections were performed on the upper limbs of twenty-three cadaver specimens. The SBRN emerged between the brachioradialis (BR) and extensor carpi radialis longus (ECRL) tendons, at an average distance of 8.65cm proximal to radial styloid apophysis (RSA). In six cases (26%) there was an acessory tendon of the BR, and the SBRN emerged between that point and the main BR tendon. The first branch of the SBRN arose at an average of 4.58cm proximal to the RSA. A branch, running directly across the RSA, was found in 30% of the cases. At the level of the RSA, the average number of branches crossing the wrist was 3.4. A fascicle count was peformed in twenty anatomical dissections of the nerve and its branches crossing the wrist at the level of the RSA. There was an average of 6.6 fascicles in the SBRN, at its point of entry between the tendons of the BR and of the ECRL. The first branch of the SBRN at the level of the RSA, had an average number of 4 fascicles. There are no similar histological studies in the literature available and thus, the results may be of help when using the SBRN for nerve grafting. The results of the anatomical findings of this study are very similar to those in the literature. The findings in the present study can contribute to a better knowledge of the SBRN, as required during such surgical procedures as the percutaneous bone fixation of the distal one-third of the forearm and of the wrist
