Abstract
Studies of the mechanics of the anterolateral abdominal wall musculoaponeurotic apparatus in healthy individuals are basic to appreciate the Pathophysiology of ventral hernia ,its pathological consequences and their impact on the functions of the abdominal wall. This study included sixty one people, twenty five of them are suffering from ventral hernia and the other thirty six are controls. multislice CT scan was used to study dynamics of the abdominal wall during rest and straining. The current study results ssuggest that: The site of the PUH defect was invariably related to the third tendinous intersection site, with a sac deflected to one side of the midline; 16 to the right side and 9 to the left side. The third tendinous intersection is at a relatively higher position on the side of the hernia defect in the majority of cases. Comparing cases with PUH and controls at rest showed a decreased rectus muscle thickness in all segments in cases. Furthermore there is a wider distance between the two recti in the third and fourth rectus sheath segments in cases. in the umbilical segment, there is a statistically significant increase in rectus muscle width,compliance angle and the AP diameter at rest when compared to the controls
