Quality of life and prognostic factors after intra-articular tibial pilon fracture

Abstract

Background: Intra-articular tibial plafond fractures are a challenge for the surgeon with generally poor functional outcomes. The purpose was to assess the impact of this injury on patient quality of life (QOL), as well as analyzed the predictor factors.

Methods: Retrospective study of 47 patients with mean age of 44.4 (range 18-79) years. Patients were also invited for new clinical and radiological assessments. QOL was evaluated by the Short Form-36 questionnaire and compared to the standard in the age-matched general population. Olerud-Molander ankle score (OMAS) was used to assess function. Digital radiographs were evaluated for linear and angular measurements.

Results: The mean follow-up at last visit was 5.3 (range, 2-10) years. Sequelae were present in 20 patients, mainly including chronic pain (8) and arthrosis (10). Articular step-off at least 2mm was present in 20 patients had, articular gap greater than 2mm in 13, and malalignment in 5. Worse reduction was obtained with external fixation. QOL was significant lower than age-matched general population (p=0.000). Main prognostic factors of worse SF36 were fracture severity, reduction quality and arthrosis. A strong significant relationship was found between SF36-physical and OMAS scores (p=0.000).

Conclusion: Intra-articular tibial plafond fracture had a dramatic impact on QOL. Among the predictors of unsuccessful outcome, the reduction quality was the only modifiable factor by the surgeon. The OMAS had a predictive value on the prognosis of QOL.
