Open reduction and internal fixation with bone grafting for treatment of calcaneal displaced intra-articular fracture

Objective: To evaluate the clinical effect of open reduction and internal fixation with bone grafting for treating calcaneal displaced intra-articular fracture.Methods: Forty-one calcaneal displaced intra-articular fractures in 35 patients were included in this study.Among the patients,29 were male and 6 were female,and the average age was 33.1 years(16 to 57).The lesions of 18 cases were in left foot,11 in right foot,6 in both feet.The Bhler angle of 19 cases ranged 0° to 15°,22 less than 0°.Classification of calcaneus fracture was done according to Sanders′ computed tomographic classification system.There were 14 cases of type Ⅱfractures,23 type Ⅲ fractures and 4 type Ⅳ fractures.Open reduction and internal fixation with the ordinary blade plates for calcaneus and bone grafting were performed.Results: Forty-one cases were followed up for an average of 18 months,and the clinical results were evaluated with the Maryland foot score.Thirty-one cases achieved excellent results,7 good,6 fair,1 failure,with the rate of excellent and good results being 92.7%(38/41).Conclusion: Open reduction and internal fixation is an excellent operative method to treat the displaced intra-articular fracture of calcaneus,and the combination with bone grafting has the advantage of preventing subtalar joint collapse and early weight-bearing.
