Abstract: Objective: To investigate the efficacy of open reduction and internal plate fixation in treating intra-articular calcaneal fracture.Methods: Thirty-two cases of intra-articular calcaneal fracture were treated with open reduction and internal plate fixation.All the cases were followed up and Kerr assessment score was used to evaluate the therapeutic effect.Results: The follow-up lasted for 12-24 months.All the fractures healed 4 months after the operation.The Kerr assessment score showed that the results were excellent in 12 cases,fair in 16 cases,poor in 3 cases and bad in 1 case.The fine rate was 87.5%.Conclusions: Open reduction and internal plate fixation is a good method for treatment of displaced intra-articular calcaneal fractures.Open reduction can also restore the articular congruency,the shape and alignment of the calcaneus.
