Abstract
Objective: Various surgical techniques have been reported in treating calcaneal malunions over the decades, while the operations on single plane were accompanied by respective limitations. The purpose of this study is to evaluate the efficacy of a novel multiple reconstructive osteotomy for treating malunited calcaneal fractures without subtalar joint fusion.Methods: From March 12, 2010, to August 17, 2017, 10 patients (10 feet) with malunited calcaneal fractures were treated with multiple reconstructive osteotomy with subtalar joint-preserving operations. All patients were treated with a corrective osteotomy, joint realignment, soft tissue balancing, and secondary internal fixation at a mean of 5.6 +/- 2.41 months since the initial injury. With the utilization of the multiple reconstructive osteotomy, the posterior facet was restored to preserve the subtalar joint. All patients were evaluated clinically and radiographically at a mean follow-up of 3.04 +/- 1.21 years. Results: All patients were subjectively satisfied with the treatment. The average time to union was 12.2 +/- 1.11 weeks. The American Orthopedic Foot and Ankle (AOFAS) ankle and hind foot score was 86.3 +/- 4.45 (t = 27.64, P < 0.0001, paired t -test), which was significantly higher than the preoperative assessment. Postoperative radiographic assessment revealed great improvement in Bohler's angle (from 25.4 degrees to 86.3 degrees), talocalcaneal height (65.15-72.68 mm) and Calca-neus-talus angle (from 34.46 degrees to 39.7 degrees). One patient had mild discomfort after a 1-h brisk walk. One patient was suspected to have early posttraumatic arthritis of the subtalar joint based upon radiographic evidence during the follow-up, but the patients could walk normally for a long time without pain.Conclusion: Multiple reconstructive osteotomy is an effective way to restore the calcaneal morphology and preserve the subtalar joint for selected calcaneal malunion.Keywords
