Clinical and Functional Outcome of Subtalar Arthrodesis in Post Traumatic Subtalar Arthritis

Dr. Javed Bhatti | Dr. Amit Agrawal | Dr. Govind Sharma

Abstract: Introduction: Fractures resulting from intraarticular malunion of the calcaneus may be associated with chronic pain and functional limitations of the subtalar joint. The purpose of this study is to evaluate the effectiveness of subtalar arthrodesis technique in subtalar arthritis caused due to malunited calcaneum fracture; utilizing double lag screws from the calcaneus to the talus along with autograft from Iliac Crest and assess the functional outcome. Material and Methods: Over the course of July '20 through February '22, we performed 20 isolated subtalar arthrodesis from calcaneus to talus using double lag screw technique and autograft from Iliac crest. A total of 12 males and 8 females participated in the study. Results: In total, 18 of the 20 joints were fused except for 2; out of which one went unfollowed and the other one dies due to some other co-morbidity, resulting in an overall fusion rate over 90%. On average, fusion took 13 weeks. Conclusion: In 90% of the cases, double lag screws 6.5 mm long across the posterior facet of the subtalar joint and Iliac crest autograft resulted in fusion of the joints. Using this technique, pain relief was obtained in 100% of cases. It is an easy and reliable way to achieve fusion of the subtalar joint.
