Three dimensional analysis of factors affecting the prognosis of calcaneal fractures

Abstract Purpose Analyzing the correlation between patients’ basic information, three-dimensional parameters after calcaneal fractures, and the prognosis of calcaneal fractures. Methods A retrospective analysis was conducted on 43 patients with calcaneal fractures who underwent surgical treatment in the Foot and Ankle Surgery, Xi’an Honghui Hospital, from September 2019 to August 2022. Patient demographics including gender and age were collected, as well as the preoperative posterior articular surface collapse area, number of fracture fragments, length, width, height, and volume of the calcaneus obtained from preoperative three-dimensional imaging. Patients were followed up for VAS, AOFAS, and SF-36 scores. Correlation analysis was performed on the obtained data. Results All 43 included patients received complete follow-up, including 40 males and 3 females, with an average follow-up time of 35.37 ± 10.73 months, and an average age of 43.98 ± 12.08 years. All patients’ VAS, AOFAS, and SF-36 scores at the last follow-up showed no correlation with patient age, gender, or the area of posterior articular collapse, number of fracture fragments, length, width, height, or volume of the calcaneus. Conclusions The prognosis of calcaneal fractures is unrelated to three-dimensional factors such as patient age, gender, length, width, height, volume of the calcaneus, area of the posterior joint, and number of fracture fragments.
