AbstractThe ideal treatment for displaced intraarticular calcaneal fractures is still under debate. Open reduction and internal fixation is the most popular surgical procedure; however, wound complications, hardware failure and infection remain a major concern. The aim of this study was to evaluate the results of a new minimally-invasive surgical procedure: closed reduction technique combined with balloon-assisted fracture augmentation with cement or calcium phosphate (minimally-invasive percutaneous calcaneoplasty). We retrospectively reviewed 11 patients that sustained Sander's type II and III calcaneal fractures treated in our institution from January 2008 to June 2010. The same approach and technique was utilized in all cases. Conventional X-rays and CT scan have been performed pre- and post-operatively. The average follow-up was 24 months. The American Orthopaedic Foot and Ankle Society ankle/hindfoot score has been utilized for clinical evaluation and Bohler's angle to assess bone reduction. All cases obtained bony union in 2/3 months, with average Bohler's angle of 22.97° (from 14.21° to 32.83°). No skin complications or adverse reactions were observed, with only one patient complaining of residual pain in the hindfoot. Minimally-invasive percutaneous calcaneoplasty can represent an alternative to open reduction internal fixation in the treatment of calcaneal fractures, allowing stable reduction without plating, early function recovery and short hospital stay.
