Abstract
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. MAIN OUTCOME MEASUREMENTS: A visual analog score for pain and function, the short-form 36 (SF-36) general health outcome questionnaire, the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot scale, and Olerud-Molander score. We compared age, sex, fracture type (Sanders classification), treatment given, Böhler angle, residual articular surface step-off at healing, type of occupation, and injury insurance between the 2 groups. RESULTS: Patients of the superior group had higher physical SF-36, AOFAS, and Olerud-Molander score than in the inferior group. Operative treatment, better Böhler angle and articular surface restoration, light labor/retirement, and absence of injury insurance were more common in the superior group. Age, sex, pretreatment Böhler angle, and fracture type were comparable in the superior and inferior groups. CONCLUSIONS: The decision making for definitive treatment of intraarticular calcaneal fractures is multifactorial with a spectrum of results and trends such as patient demographic features that should be considered in choosing the best treatment option. LEVEL OF EVIDENCE: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.
