Current concepts in triple arthrodesis

When performed appropriately, good to excellent results may be obtained with triple arthrodesis in about 80% of patients. Postoperative pain relief, a plantigrade foot, and improved ambulatory ability are the desired surgical goals. Although there is a significant incidence of degenerative or compensatory arthritis in the remaining articulations, it is rarely of clinical significance. The surgical technique of triple arthrodesis is technically demanding. Rigid attention to detail is important to reduce surgical complications. It is important to understand the local anatomy to avoid injury to nerves, vessels, and tendons. Proper exposure of the joints facilitates cartilage removal and lowers the incidence of nonunion. Rigid compression fixation in an appropriate position provides the best possibility of a successful outcome. It is crucial to remember that a triple arthrodesis is an end-stage salvage procedure. With realistic expectations, the level of satisfaction will be higher for both patient and surgeon.
