In Sanders' classification of calcaneus fractures, the medial fracture line (subtype C) is close to the tarsal canal, which contains an artery for the talus and calcaneus. We hypothesized that because of this brittle vascular localization, patients with C line fracture patterns might describe radiologic subtalar arthritis more often and have more complaints. The purpose of the present study was to compare the results of C line fracture patterns with other types of calcaneus fractures. A total of 25 surgically treated feet were involved. Regarding Sanders' classification, group 1 included fractures involving the C line (11 feet), and group 2 included fractures not involving the C line (14 feet). Patient age at admission, trauma date, and interval until surgery were obtained from the patients' medical records. The Bohler angles were determined from the radiographs. At the last follow-up visit, the radiologist graded subtalar arthritis using computed tomography. For clinical follow-up, the American Orthopaedic Foot and Ankle Society and Maryland scores were assessed. No significant differences were found in mean age, follow-up period, delay to surgery, or postoperative Bohler angle between the 2 groups. The mean preoperative Bohler angle was significantly low for group 1. Although not significantly different, the mean American Orthopaedic Foot and Ankle Society and Maryland scores were lower for group 1 (81.9 and 84.3) than group 2 (87.8 and 92.0), and the median subtalar arthritis grade was greater for group 1 (score 2) than for group 2 (score 1.5). The worse results with C line fracture patterns despite satisfactory reduction might result from sinus tarsi artery damage. Angiographic investigations could clarify this theory in the future. Consequently, surgeons must inform and should hesitate to operate on patients with these highly comminuted C line calcaneus fractures. (C) 2011 by the American College of Foot and Ankle Surgeons.
