Popis: Category: Trauma; Hindfoot Introduction/Purpose: High energy calcaneus fractures have significant soft tissue compromise and typically poor outcomes. The purpose of this study was to describe patient complications and outcomes, after undergoing staged treatment for high energy calcaneus fractures, including initial treatment with medial calcaneal external fixation followed by definitive reconstruction. Methods: A retrospective chart review with prospective data was performed from April 2013 to February 2019. Inclusion criteria for the study included: patients >18 years of age, closed Sanders III and IV fractures or open fractures of the calcaneus. Patients were initially treated with placement of a medial based external fixator with closed reduction. Once the soft tissue envelope had improved, definitive fixation was performed, either ORIF or ORIF with primary subtalar fusion. Results: There were a total of 15 patients that met inclusion criteria for the study. 9 of the fractures were open and 6 were closed. The medial calcaneal external fixation (ex-fix) was placed at a mean of 2.0 (0-12) days after initial injury. The definitive procedure occurred at a mean of 23.6 (12-42) days after ex-fix placement. 11 of the patients underwent calcaneus fracture ORIF with primary subtalar (ST) fusion and 4 patients were treated with calcaneus fracture ORIF alone. 14 (93%) of the patients showed radiographic union at an average of 6.7 months. Mean PROMIS scores showed improvement in physical function, mood, and a decrease in pain at an average of 19 (5-72) months after initial injury. The average VAS pain score was 3.5 (0-7). Conclusion: A staged protocol for high-energy and open calcaneal fractures is an effective tool in treating these difficult injuries. It allows the soft tissues to improve while maintaining length and alignment of the fracture for definitive fixation and minimizing complications. There were improvements in physical function, mood, and a decrease in pain at final follow-up of almost 2 years.
