The separation of anatomic components technique for the reconstruction of massive midline abdominal wall defects: Anatomy, surgical technique, applications, and limitations revisited

Learning Objectives: After studying this article, the participant should be able to: 1, Describe the anatomic muscle complex that is advanced toward the midline in the separation of components method of abdominal wall repair. 2, Understand the indications for components of separation reconstruction of the abdominal wall and the maximum transverse defect width that can be reconstructed at various levels. 3, Describe the course of the intercostal nerves lateral to the linea semilunaris line as they run posterior to anterior. 4. Understand the plane of dissection necessary to develop this muscle complex and be aware of the technical maneuver to increase the mobility of this complex at the costal margin, waist, and suprapubic area.
