Abstract
Introduction: Involvement of the subtalar joint in fracture calcaneus malunion may give rise to chronic pain and permanent functional impairment. This study evaluated the functional result of subtalar joint fusion and effectiveness of a technique using double lag screw from the posteromedial calcaneus to the talus. Materials and Methods: In between April 2015 and April 2017, we performed 12 isolated subtalar arthrodeses by double lag screw technique from posteroinferior calcaneus to talus. The average patient age was 39 (range 28–50) years. There were 9 males and 3 females. Results: Eleven out of 12 joints were fused except one who developed infection, resulting in an overall fusion rate of above 91%. The average time for fusion was 4.5 months (ranging from 3 to 6 months). There was no correlation between the type of accident, the weight of the patient, and the recovery period. Conclusion: Using the double lag screws of 6.5 mm across the posterior facet of subtalar joint resulted in fusion of joint in above 91% of patients. The relief from pain was obtained in 100% of cases. This is a simple and reliable technique for achieving fusion of the subtalar joint.
