Cadaver as an experimental a model for the study of midline incisional hernia.

Purpose: To describe a cadaver model and to compare different techniques to correct midline incisional hernia using the tension at the musculoaponeurotic layer as a parameter.

Methods: Twenty-four male cadavers were used to characterize the model. The tensile force applied to the anterior layers of the rectus abdominis muscle was measured after the linea alba was resected to create an abdominal wall defect.

Mapping traction strength of the anterior rectus sheath in cadaver.

Purpose: The tension at the aponeurotic edges of abdominal wall defects is an important factor of dehiscence and incisional hernia formation. The purpose of this study is to map and compare the traction force necessary for medial mobilization in various levels of the anterior rectus sheath in cadavers.

Methods: Twenty four adult male cadavers, raging from 22 to 59 years old, with the abdominal wall intact and without prior preservation techniques, were dissected.
