BackgroundFor displaced intra-articular calcaneal fractures (DIACFs), the less invasive surgical techniques vary widely. Herein, the study is to introduce a novel, reliable and reproducible protocol of three-step closed reduction (distracting, elevating, and clamping) and percutaneous screw fixation for DIACFs.MethodsThis retrospective study included 32 patients with 33 DIACFs treated by the abovementioned surgical procedures with an average follow-up of 17.7 months. Postoperative outcomes were evaluated by complications, radiographs, and functional scores.ResultsThere were no incision complications. Postoperative Böhler's angle, height, and width were significantly recovered with p < 0.001. Especially, mean postoperative subtalar incongruity was 0.5 ± 0.5 mm. The average values of Maryland Foot Score (MFS) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot score were 93.6 ± 5.9, 91.7 ± 6.7, respectively. The average scores of short form-36 (SF-36) and visual analog scale (VAS) were 89.9 ± 10.4 and 3.1 ± 1.6, respectively. Further subgroup analysis showed that the functional scores were comparable among different fracture types according to either Sanders or Essex-Lopresti classification.ConclusionWe consider the three-step reduction (distracting, elevating and clamping) and percutaneous screw fixation to be a reliable and reproducible protocol for the treatment of DIACFs.Copyright © 2022.
