Objective: the examine variants of quantity of intercostal nerves in the area of the lateral edge rectus sheath around umbilical region, depending on the shape of the anterior abdominal wall. Materials and methods: There were studied 88 floating corpses of both sexes without pathology of the anterior abdominal wall. Among them there were 45% male corpses (mean age – 53,8±11,9 years) and 55% – female corpses (51,9±13,2 years). We measured linea bicostalis, linea bispinalis and linea xiphoidopubica, determined quantity of the intercostal nerves in the umbilical region of the anterior abdominal wall. Results: At the study of anthropometric parameters of the anterior abdominal wall were found that linea bicostalis averaged 29,2±0,3 cm, linea bispinalis – 28,2±0,2 cm, linea xiphoidopubica – 30,4±0,5 cm. Using method of cluster analysis of the new data were obtained the main shapes of anterior abdominal wall: male, oval, female. It was found that persons with a female shape of the anterior abdominal wall was observed significantly more often 2 pairs of intercostal nerves (74%). In turn, at persons with oval shape were often observed 3 pairs of intercostal nerves (60%). In the cases of the male shape of the anterior abdominal wall 1 pair of intercostal nerves were observed in 38%, and 2 pairs of nerves – in 50% of cases. Conclusions: The quantity of intercostal nerves in the area of the lateral edge rectus sheath around umbilical region depends on the shape of the anterior abdominal wall.
