Equally, the sensitive anastomosis between the median nerve (MN) and the ulnar nerve (UN) in the hand, and the superficial palmar arch (SPA) variants have been broadly publicised to be of clinical and surgical significance. In this study, we aim to analyse metrically, topographic relations between this nervous anastomosis to both the SPA and the transverse carpal ligament. Material and methods 30 10% formalin‐fixed adult human cadavers' hands, readily available at the Department of Morphology of Santa Casa de Sao Paulo School of Medical Sciences, have been dissected in order to evaluate primarily, the SPA formation pattern classified in accordance to five types proposed by Loukas et al, 2005. Deep dissection henceforth ensued in 15 specimens to expose the MN and UN ramus and their potential coupling in four patterns as suggested by Meals & Shaner, modified by Bas & Kleinert, 1999. Results Amongst our samples, the SPA variants distribution has been of: 11 (36.7%) type S‐I, 13 (43.4%) type S‐II, 1 (3.4%) type S‐III, 1 (3.4%) type S‐IV and 4 (13.4%) S‐V. MN and UN distal anastomosis has been found in four hands, three type‐I, and one type‐III: type‐I cases ran profoundly to the APS, and type‐III mean distance to the SPA was 1.6 cm distally. Conclusion We have been able to assess a topographic relation between the SPA and the sensitive anastomosis in the hand potentially valuable to clinics and surgery; nonetheless, we encourage forward study in this regard.
