Factors Affecting Long-Term Treatment Results of Displaced Intraarticular Calcaneal Fractures: A Post Hoc Analysis of a Prospective, Randomized, Controlled Multicenter Trial

摘要

Objectives: To study the factors affecting long-term treatment results of displaced intraarticular calcaneal fractures (DIACFs).Design: A post hoc analysis.Settings: Tertiary care teaching hospitals.Patients: Eight to twelve years of results from a randomized controlled multicenter trial of operative versus nonoperative treatment (n = 56) were divided into 2 groups: the superior 50% results (n = 28) and the inferior 50% results (n = 28), regardless of the treatment given. The determinant of this division was a visual analog score for pain and function.Interventions: The operative treatment consists of open reduction and internal fixation, whereas the nonoperative treatment consists of nonweight bearing and early range of motion exercise.
