The mid-term effects on quality of life and foot functions following pilon fracture.

Background: Although pilon fractures are uncommon, they are of importance to orthopaedic surgeons because of the difficulty of treatment. Poor outcomes and high complication rates are seen despite various surgical methods. This study aims to examine the changes affecting the quality of life and foot functions in patients applied with open reduction and internal fixation (ORIF) for a pilon fracture.

Methods: In this study, a total of 45 patients treated with ORIF for a pilon fracture in our clinic between January 2010 and December 2016 were evaluated with AOFAS and SF-12 in a total of 10 categories according to demographic data, fracture classification and surgical technique. In addition to functional values, patient records were examined regarding complications, including infection, soft-tissue defect, malalignment, non-union, arthrosis and Sudeck atrophy. In patients with AOFAS <85 and low SF-12 scores, variables were examined and the relationship with complications was evaluated.

Results: The mean follow-up period was 3.7 years (range 2 to 7). The AOFAS value was determined to fall to <85 when the Ruedi Allgower classification increased (p=0.010), when AO classification increased (p=0.020), when there was a concomitant lateral malleolar fracture (p=0.028), and when the status was non-anatomic according to the Ovadia Bell criteria (p=0.031). The SF-12 PCS value was observed to decrease when the Ruedi Allgower classification increased (p=0.018) and when the status was non-anatomic according to the Ovadia Bell criteria (p=0.012). A correlation was determined between the SF-12 PCS and the AOFAS values (p=0.000).

Conclusion: The reasons for the failure of ORIF in tibia pilon fractures were found to be Ruedi 3 classification, concomitant lateral malleolar fracture, and non-anatomic surgical reduction. Failure in foot functions has a direct effect on quality of life in both the short and mid term.
