ABSTRACT From 1990 to 1992, all arthrodeses of the socalled triple joints, combined or isolated and performed by one surgeon, were reviewed to allow a minimum follow up of 18 months from the time of the index procedure. Type of bone graft was selected based on the patients' decision after the risks of each were explained by the surgeon. There were 37 patients undergoing 41 procedures (4 bilateral) including double and triple arthrodesis, as well as isolated subtalar fusions. Twenty-nine of these were performed for either degenerative or posttraumatic arthritis. Ten others were performed for joint incongruity resulting from posterior tibial tendon insufficiency, and the rest for hemiparesis or residual clubfoot. All patients were placed into a routine postoperative regimen of casting, bracing, weight bearing, and therapy. They were evaluated based on subjective complaints, physical examination, and postoperative radiographs. Any patient suspected of having a nonunion underwent a computed tomography scan for confirmation. Overall, 24 patients received allografts and 17 iliac crest grafts. There were four nonunions, three of which utilized banked bone graft, with the only nonunion in the autograft group occurring in a patient following open calcaneus fracture. Of the four nonunions, three opted for revision surgery and the only one to choose allograft again incurred the only recurrent nonunion. There were two infections, one in each group, resulting in prolonged intravenous antibiotic therapy.
