Objective: To evaluate the functional and radiological outcomes of anterograde headless cannulated screw fixation for medial malleolar fractures. Subjects and Methods: This study included 12 patients (8 males, 4 females; age 27-55 years) with medial malleolar type B fractures according to the Herscovici fracture classification who had undergone anterograde headless cannulated screw fixation surgery between 2012 and 2014. Seven had an isolated medial malleolar fracture and 5 a bimalleolar fracture. All of the bimalleolar fractures were classified as 44-B2 based on the Arbeitsge-meinschaft fur Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) classification. Postoperatively, bone union was evaluated on direct radiographs at the final follow-up examination. The American Orthopaedic Foot and Ankle Society (AOFAS) scoring system was used for clinical evaluation. Results: The mean follow-up period was 17.2 +/- 5.3 months (range 12-23). Full union was achieved in all fractures. The mean time to union was 3.4 +/- 1.5 months (range 2-5). No instability, loss of reduction, non-union or infection was observed in any patient. The mean AOFAS score was 95.0 +/- 5.4 (range 87-99). Based on the AOFAS score, 4 patients showed good results and 8 excellent results. The mean time to return to the previous level of activity was 4.0 +/- 2.5 months (range 2-5). Conclusion: In this study, anterograde headless cannulated screw fixation yielded good clinical outcome in the surgical treatment of Herscovici type B fractures. (C) 2016 S. Karger AG, Basel
