From PubMed - Unna boot:
For many decades, few advances occurred in the treatment of venous ulcers. Clinicians mainly relied on compression using
gauze impregnated with zinc oxide--the Unna boot.One of the most common and effective treatments for venous stasis ulcers (VSUs) is the Unna boot dressing (UBD), first
described by Unna in the 1890s.
and in 1854, Unna described in Vienna the supportive boot which now carries his name.
