Mid-term results of intra-articular calcaneal fractures treated with minimally invasive two-point distractor : Single center study with 6-year follow-up.

Background: Displaced intra-articular calcaneal fractures are a complication-ridden injury to treat and there are various treatment techniques to address this injury. The aim of this study was to evaluate the mid-term outcome of a percutaneous two-point distractor technique in patients with displaced intra-articular calcaneal fractures.
Methods: A retrospective data analysis of patients with intra-articular calcaneal fractures treated in a level 1 trauma center was conducted. The patients were subsequently invited for a follow-up visit to assess the mid-term outcome. The Böhler's and Gissane's angles, the American Orthopaedic Foot & Ankle Society hindfoot score, the Maryland foot score and a visual analog scale for pain were measured preoperatively and postoperatively and after at least 6 years to assess the radiological and functional outcome.
Results: Of the patients 59 completed the study with a mean follow-up of 76 months after surgery. The mean American Orthopedic Foot and Ankle Society hindfoot score at the last follow-up visit was 81, the mean Maryland foot score was 78. There were three cases (5%) of superficial wound complications and secondary arthrodesis of the subtalar joint was performed in five patients (8%).
Conclusion: The low rates of postoperative infections and secondary arthrodesis in this study underline the good to excellent mid-term functional results for a minimally invasive technique.
