Tibiocalcaneal arthrodesis: A comparison of anterior approach and transfibular approach

OpenAlex İngilizce

Objective: The aim of this study was to evaluate the clinical and radiologic results and complications of patients who underwent ankle arthrodesis performed by the transfibular approach and anterior approach in end-stage ankle osteoarthritis. Methods: Between 2016 and 2022, 41 patients who satisfied the inclusion criteria for this retrospective comparative analysis were included. Of them, 19 patients are included in the anterior approach group and 22 patients are included in the transfibular approach group. The mean age of the participants is 58.9 years. Collected data included the BMI, American Orthopedic Foot and Ankle Society (AOFAS) hindfoot scale, visual analogue scale (VAS) score, diabetes, smoking, time to fusion, nonunion, union rate, preoperative and postoperative coronal tibiotalar angle and complications. Result: The mean time to bone union was 14.3 weeks (range 11-17 weeks) in the anterior approach group, and 11.3 weeks in the transfibular approach group. Statistically significant difference was found between the two groups. Nonunion occurred in one case in the transfibular approach group and three cases in the anterior approach group. There was no significant difference in the nonunion rate between the both groups (p = 0.321). VAS score, and AOFAS score of the two groups were similar and no significant differences were found (p = 0.491, p = 0.448, p = 0.146, p = 0.073, p = 0.173, p = 0.506, respectively). Conclusions: A stable and firm ankle arthrodesis and plantigrade foot can be achieved with both transfibular approach and anterior approach technique.
