A Comparative Study On Poking Reduction And Open Reduction With Internal Fixation In Treatment Of Sanders II & III Calcaneal Fractures

Objective : To compare the curative effect of poking reduction with cannulated screw and open reduction with internal fixation in treatment of Sanders II-III calcaneal fractures.Methods:From September 2012 to January 2014, 48 cases of fresh calcaneal fractures sought for treatment in China-Japan Union Hospital of Jilin University, 24 of them were treated with open reduction, and the other 24 with poking reduction. All the patients were followed for 8-15 months, the average follow-up time was 12 months. The affected foot Maryland score, postoperative excellent rate, Bohler’s angle, Gissane’s angle, the hospitalization time and complication rate were recorded to evaluate the operative effect. The data were statistically processed, the value is α=0.05 as a standard test, P <0.05 was considered statistically significant difference.Results :Two groups of patients compared with the preoperative received effective treatment. In the Maryland foot scores and postoperative excellent rates, the effects were little better in opening group than in poking group and there was no statistical significance among the two groups(P >0.05). Bohler’s angle and Gissane’s angle were improved in both groups after surgeries but the improvements of Bohler’s angle and Gissane’s angle between the two groups had no significant difference in angle( P >0.05). In the post-operative complication rates, the effects were better in poking group than in opening group and there was statistical significance among the two groups( P < 0.05). In the length of hospital stay, the hospitalization time of opening group patients was significantly prolonged.Conclusion :Poking reduction with cannulated screw and open reduction with internal fixation are effective in the treatment of Sanders II-III calcaneal fractures, and can both restore normal anatomy of calcaneus. Poking reduction has some advantages such as small surgical injury, less damage to the soft tissue, less hospital stay and less postoperative complications, and it is an effective, practical and worthy of promoting operative procedure.
