Introduction: Calcaneal fractures are the most common of all tarsal fractures. The treatment of displaced intraarticular fractures is controversial. Earlier, these fractures were treated conservatively. Now-a-days these fractures are being treated surgically using various modalities. Purpose: 1. To analysis the radiological and functional outcome of surgical fixation of open and closed displaced intraarticular fractures and post operative complications 2. To determine whether it is beneficial in maintaining restoration of Bohler’s and Gissane angles, calcaneal height and anatomical articular reconstruction. Material and methods: This study included patients age between 18-60 years. A sample of 20 patients with Intraarticular displaced or comminuted calcaneal fractures were selected, evaluated and operated in Rajah Muthiah Medical College and Hospital, Chidambaram between July 2019 to October 2021. All the patients underwent surgery, fixed with anatomical plates or k wires or CC screw. Follow up was done clinically and radiologically at 6 weeks, 12weeks, 6 months, and 1 year. Results: Out of 20 patients, 17 had intraarticular fractures and 3 had comminuted fractures following fall from height, out of which 9 patients treated with calcaneal plate and 6 patients with k-wires and five patients with CC screw. Out of 20, 11 had excellent results with Modified Maryland Foot Score more than 90, 8 had good results with score of more than 75. 1 fair of score less than 75 and 11 recovered without complications, 5 with subtalar arthritis and 4 with Heal Pain. Conclusion: From our study we conclude that surgical fixation of calcaneal fractures offers excellent post operative functions with early mobilisation, early union and less complications.
