Background: The biggest tarsal bone is the calcaneus. The calcaneus is the tarsal bone that breaks most frequently. One of the most difficult injuries for an orthopaedic surgeon to treat is a fracture of the calcaneus. 90% of calcaneal fractures in males between the ages of 21 and 45 have a significant socioeconomic impact since patients with this injury frequently take extended amounts of time off from job and regular activity. Calcaneal fractures may occur intra-articularly (involving subtalar joint) or extra-articularly, (sparing the subtalar joint). About 75% of calcaneal fractures are intra-articular fractures, which have been linked to poor functional outcomes. The best course of action for treating displaced intra-articular calcaneal fractures is still up for debate. According to the research, surgical intervention is preferable to non-operative therapy in patients with displaced intra-articular calcaneal fractures, patients with decreased Böhler's angle, and youthful, active, cooperative patients who are light to moderate workers. In this study, we are evaluating the results of surgical treatment of calcaneal fracture with open reduction and internal fixation. Materials and Method: This study was carried out at the Department of Orthopaedics, Navodaya Medical College, Raichur over a period of 2 years. In this study, 21 patients ranging in age from 22 to 54 years with calcaneal fracture were admitted and were treated by open reduction and internal fixation through lateral extensile approach or any other approach as required. Functional outcome was assessed by AOFAS, MFS scoring system. Results: A total of Twenty one patients were evaluated in our study of which all were males. According to AOFAS score, 23.8% patients had excellent results, 61.9% had good results and 14.2% had fair results and according to MFS score 9.5% had excellent results, 71.4% had good results and 19.1% had fair results at the end of nine months. Conclusion: The intra articular calcaneal fractures are potentially debilitating and open reduction and internal fixation gives better functional outcomes as compared with other modalities of treatment.
