Epigastric, para-umbilical, umbilical and
The mechanism and development of these types of hernias and the defects
through which they protrude are demonstrated. An approach to management
of each type is presented.

These diagram shows the general
structure of the abdominal wall. It shows the 3 main muscles in
brown. These muscles fuse and form a large aponeurotic tendon sheet
(termed the rectus sheath) and this encloses a single strap-like
muscle - the rectus abdominis muscle - the rectus sheath fuses in
the mid-line to form the linea alba (white). Because this is a single
layer here this is a potential weakness and thus a common site where
hernias develop - termed 'epigastric' hernias.
