PurposeTo evaluate the outcome of displaced intraarticular calcaneal fractures (DIACFs) of a case series of patients who were treated with a percutaneous fixation technique.Materials And MethodsEight patients were operated for DIACFs and they were evaluated for the outcome and complications in a mean follow up of 9 months (range: 6 - 12 months). At the last follow up the AOFAS score, the Boehlers' angle and the presence of any complication were noted. The time from injury to surgery was also reported. The correlation of the AOFAS score and the development of post traumatic subtalar arthritis to the type of fracture, to the post operative Boehler's angle and to the time from injury to surgery were investigated.ResultsThe overall mean AOFAS (Americal Orthopaedic Foot and Ankle Society) score was 84,625 (Range: 73 - 96). The mean AOFAS score of type II and type III fractures was 87,667 and 75,500 respectively. The mean AOFAS score for fractures with a postoperative Boehler's angle of less than 10° and more or equal to 10° was 76,750 and 92,500 respectively. This difference was found to be statistically significant. The mean AOFAS score for fractures who were treated less or equal to six days and more than six days post injury was 91,250 and 78 respectively. Two out of four patients with a post operative Boehler's angle less than 10° developed post traumatic subtalar arthritis. No patient out of four for whom a Boehler's angle of more than 10° has been achieved, developed subtalar arthritis. No infection occurred in any of the patients.ConclusionPercutaneous fixation is a safe and effective way of treating DIACFs. The outcome is directly related to the quality of reduction, which is significantly dependent to the timing of surgery. The earlier the fracture is operated the better the reduction by closed means is.Copyright © 2023 Elsevier Ltd. All rights reserved.
