Entrance wound locations. (A) Front; (B) back. Numerator depicts the number of diaphragm injuries. Denominator depicts the total number of entrance wounds in that area.

3. Fig 2
Diagnostic algorithm for diaphragm injuries following penetrating chest trauma. (1 = The chest is immediately evaluated with an upright chest x-ray (CXR); 2 = The abdomen is evaluated for injury utilizing diagnostic peritoneal lavage (DPL) or computed tomographic (CT) imaging; 3 = Patients with an indication for celiotomy or thoracotomy have their diaphragm evaluated at the time of surgery. VATS = video assisted thoracoscopic surgery.)

4. Fig 3
Diagnostic algorithm for diaphragm injuries (DI) following penetrating chest trauma. (1 = Patients whose history or physical exam identifies two or more (≥ 2) predictors of DI should undergo video-assisted thoracoscopy to exclude an occult DI; 2 = Patients with less than two (< 2) independent predictors of DI have a risk of occult diaphragm injury too low to justify the routine use of video-assisted thoracoscopic surgery (VATS). Abd = abdomen; CXR = chest x-ray; MRI = magnetic resonance imaging.)
