ABSTRACT

 
BACKGROUND: The intermediate outcome of patients who underwent a triple arthrodesis for the treatment of adult foot disorders was evaluated with an outcome tool to determine if their pain and functional status were improved.
 
METHODS: We evaluated 63 feet in 57 patients who underwent a triple arthrodesis using rigid internal fixation for the treatment of hindfoot deformities associated with symptomatic arthrosis. Twenty-four men and thirty-three women, with an average age of 54 years, were evaluated. The average follow-up was 30 months.
 
RESULTS: Multiple diagnoses contributed to hindfoot deformities with secondary arthrosis. Iliac crest bone graft was used in 56 of 63 cases (89%). Percutaneous heel cord lengthening was done in 53 of 63 cases (84%). Twenty-four of the thirty patients (80%) returned to work. Twenty-five patients were retired and two were unemployed before surgery. All patients except two (97%) were satisfied with the surgery and would have the surgery again. The average American Orthopaedic Foot and Ankle Society Ankle-Hindfoot preoperative score was 28 points and the average postoperative score was 81 points (P < 0.0001). In the radiographic measurements, there was an average improvement of 12 degrees in the lateral talometatarsal angle, 7 degrees in the lateral talocalcaneal angle, and 10 degrees in the AP talometatarsal angle (P < 0.0001). Complications experienced included two varus malunions, two valgus malunions, two nonunions, two deep vein thromboses, one distal fibula stress fracture, and one wound infection. Of the 26 feet in 22 patients with mortise views available, 10 feet (38%) had evidence of ankle arthrosis and 19 feet (73%) had some degree of talar tilt postoperatively.
