title: Anatomical study of sensory anastomoses in the hand.
abstract: OBJECTIVE
  The aim of this study is to evaluate the prevalence, topography and morphometry of sensitive nervous anastomoses in the hand.
  
  
  METHODS
  Thirty anatomic parts irrespective of race, gender and age have been dissected. Measurements of anastomoses' length, origin and terminus regarding the transverse carpal ligament were noted. The anastomoses were classified according to the scheme proposed by Meals & Shaner and modified by Bas & Kleinert.
  
  
  RESULTS
  Type 1 anastomosis was the most prevalent. The distance between the origin of the anastomosis to the distal limit of the transverse carpal ligament was 0.7 cm in average.
  
  
  CONCLUSIONS
  This study showed that Berretini anastomosis is high prevalent, usually beginning in the ulnar and distal nerve until the transverse carpal ligament. Level of Evidence IV, Case Series.
