Effectiveness of MIS technique as a treatment modality for open intra-articular calcaneal fractures: A prospective evaluation with matched closed fractures treated by conventional technique

摘要

Twenty-five displaced intra-articular calcaneal fractures in 21 patients, aged 15-55 years were included in this study. Sanders' type I fractures, severe crushing or partial amputation, were excluded from the study. Patients were divided into group 1 (open fractures treated by MIS), and group 2 (closed fractures treated by ORIF). Group 1 had 16 and group 2 had 9 cases. Seven of 25 fractures (28%) developed wound related issues postoperatively. One patient (11.1%) in group 2 had wound margin necrosis, while 6 patients (37.5%) in group 1 developed pin tract and/or wound infection. At 1-year follow-up, the mean MFS for group 1 was 79 and mean MFS for group 2 was 84.4 (66.67% were good). The AOFAS score for group 1 was 77.37 and for group 2 was 86.1. The Bohlers' angle was restored in 81.16% cases in group 1 and 88.8% in group 2, while Gissane angle was restored in 68.75% of group 1 cases and 77.79% of group 2 cases. This study shows that acceptable fracture reduction can be obtained and maintained by MIS technique and it can be used as the primary definitive treatment option in open calcaneal fractures.
