title: Strong linea alba: myth or reality?
abstract: The traditional approach of repairing the linea alba, while operating on ventral hernias, is based on the premise that the linea alba is a strong layer and can reinforce the abdominal wall. This deeply entrenched view of most surgeons has resulted in numerous techniques which invariably include the linea alba as a part of the repair. On the contrary, this article proposes a hypothesis that the linea alba is a weak layer and varies widely in individuals with respect to its anatomy. It is especially weak in elderly, obese and multiparous patients in whom ventral hernias are common. The 'white line' - literal translation of 'linea alba' - becomes wide and attenuated in these patients; this 'white area' or 'rus alba' is more susceptible to tissue failure. We termed this the "Sick Linea Alba Complex" (SLAC) and hypothesize that the linea alba should be excluded from rather than included in the repair of ventral hernias in order to minimize recurrence rates.
