High compression therapy, whether with bandage systems or hosiery, is the accepted treatment of lower limb venous ulceration. Compression has not only been shown to improve healing, it has been demonstrated to reduce oedema and improve tissue oxygen levels (Stacey et al, 1990), reversing some of the changes associated with chronic venous insufficiency (Vandongen and Stacey, 2000).

The introduction of multilayer high compression bandage systems in the late 1980s, and subsequent improvements in bandage textiles and design, have undoubtedly improved outcomes for many patients.

However, compression alone does not address the underlying pathology of venous ulceration, chronic venous insufficiency (CVI), and without treatment CVI continues to cause skin damage and increases the risk of recurrent ulceration.

In 1999, Nelzen emphasised that compression treatment has been used since the days of Hippocrates and yet has not solved the problem of leg ulceration (Nelzen, 1999).
