Single-stage correction of constriction ring syndrome.

The accepted method of treatment for the constricting ring syndrome of the extremities is serial excision and repair with Z-plasties. A series of 4 patients operated upon in different centers by single-stage excision of the ring and multiple Z-plasty repair is presented. In 1 patient there was absence of a major nerve trunk underneath and distal to a constriction ring. None of the patients suffered any significant circulatory embarrassment. This surgical approach is anatomically sound and clinically safe. It should be considered as an alternative method of treatment to the currently accepted procedure.
