Treatment of Sanders Type IV calcaneus fractures by primary arthrodesis with VIRA system
Materials and Methods: We ran an observational descriptive retrospective trial on a pool of 13 patients hospitalized in our center with diagnosis of acute fracture of intra-articular calcaneus Sanders Type IV (total number of fractures 15), two bilateral cases, from January 2009 to December 2013, treated with surgery by subtalar arthrodesis with VIRA System.
Results: we reviewed a total of 15 fractures of calcaneus in 13 patients (2 bilateral cases), 11 men and 2 women, average age 33,84 years old (range 24-69). Radiographically, measure of Böhler degree was between 0 and 10 in 11 cases and in 4 cases the degree was negative. About the surgical technique, there were no intraoperatorial complications; radiographically there were 4 cases of divergence of the screws with no clinical relevance. Following the valuation scale of AOFAS outcomes, satisfactory results were obtained in most of e patients, with score between 79 and 96 (average 86,4). A second surgery was required in three cases.
Conclusion: VIRA system fulfills the goals of any minimally invasive surgery, efficiency and low rate of complications, by a lower surgery aggression.
