Quality of Life After Operative Fixation of Displaced Acetabular Fractures

Objective: The aim of this study was to determine quality of life (QoL) changes over time after internal fixation of acetabular fractures. Design: This pertains to a prospective cohort study, which was single centered. Setting: The study was conducted at the University Hospital. Patients: One hundred thirty-six patients (108 men, 28 women), age 17-83 years operated for an acetabular fracture during 2004-2008 were prospectively included and followed up for 2 years. Main Outcome Measures: QoL was evaluated via Short Form-36 (SF-36) and Life Satisfaction-11 at 6, 12, and 24 months. Radiographs were evaluated according to Matta at 2 years. Results: The most frequent fracture types were posterior wall (n31), associated anterior-posterior hemitransverse (n34), and associated both column (n29). One hundred twenty-nine patients could be assessed at 2 years, 4 did not respond, and 3 had died. The patients scored lower than norms in all 8 SF-36 domains with improvement over time for Physical Function (P < 0.0001) and Role Physical (P < 0.0001). The patients with postop reduction 0-1 mm scored better (P < 0.001-0.039) in 7 domains, all except vitality (P = 0.07), when compared with patients with residual displacement of >= 2 mm. Life satisfaction did not change with time and showed lower scores than normative in 9 of 11 items. Nineteen patients had undergone total hip replacement, and the strongest predictor was acetabular or femoral head impaction. Conclusions: QoL in surgically treated patients with displaced acetabular fracture keeps improving in physical SF-36 domains over a 2-year period although still lower than norms, and anatomical reduction results in better QoL outcome in most dimensions.
