Frequency distributions of biomechanical characteristics used for the design of incisional hernia repair. The median values are indicated by red bars. Left: CRIP values for primary repairs and recurrent hernias taking into account the measured tissue distension calculated preoperatively. In cases with CT scans of the abdomen at rest only, a distension value of 20% was assumed. The median CRIP values of recurrent hernias are twice those calculated for primary cases (p = 0.00714). Right: Sizes of primary and recurrent incisional hernias taken as the larger area for incisional hernia repair. The sizes to be repaired for battlefield abdominal walls with multiple incisions and larger areas of instability can expand beyond the facial defects. Sizes of recurrent hernias were twice as large as primary defects (p = 0.00694).
