Triple arthrodesis using external ring fixation and arched-wire compression: an evaluation of 87 patients.

From January 1995 to December 2000, 87 patients at a single medical center underwent triple arthrodesis using external rings and arched-wire compression as the method of fixation. A retrospective evaluation was conducted to assess the clinical results of this technique. Eighty-four patients (97%) achieved clinical and radiographic fusion in 6 to 8 weeks. All of the patients were partially weightbearing during the first postoperative week. Thirty-one patients (36%) developed a superficial infection at one or more wire insertion sites, and nine (10%) experienced dehiscence of an incision. Three patients (3%) developed an asymptomatic nonunion. This article describes the use of external ring fixation with arched-wire compression for triple arthrodesis and presents the findings from 87 patients who underwent this technique.
