OBJECTIVES: To assess the long-term functional and radiological outcome, as well as complications and reoperations of ankle fracture patients treated based on stability classification.
DESIGN: Retrospective.
SETTING: Main Trauma Center, University Hospital.
PATIENTS AND INTERVENTIONS: One hundred sixty patients were treated based on stability classification. After a mean follow-up of 12 years, 102 patients were assessed; 67 visited the outpatient clinic, and standard standing ankle radiographs were taken; osteoarthritis (OA) was graded according to Kellgren-Lawrence classification. The remaining patients (n = 35) were followed up via mail or telephone. The complications and reoperations of all 160 patients were collected from electronic patient records.
MAIN OUTCOME MEASURES: Olerud-Molander ankle score, foot and ankle outcome score, visual analog scale, RAND-36 item health survey, range-of-motion measurements, and Kellgren-Lawrence OA classification.
RESULTS: Very good to excellent ankle functional outcome was reported by 96% of the stable fracture group [mean Olerud-Molander ankle score (OMAS), 92; range, 20-100] and 82% of the unstable group (mean OMAS, 86; range, 30-100). For patients with an unstable fracture, OMAS and VAS pain scores significantly improved from 2 to 12 years, even though higher grades of radiologic OA were found. No patients with fractures deemed stable needed operative intervention even in the long-term follow-up. Instead, 30% of the operatively treated patients underwent reoperation during the long follow-up.
CONCLUSIONS: The treatment of ankle fractures based on stability-based classification led to predictable, functionally good outcomes even during long-term follow-up. Ankle fractures can reliably be deemed stable based on this classification and treated without failures in the long term.
LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
