[Functional evaluation and quality of life in the follow-up of patients with Charcot arthropathy treated by ankle arthrodesis with a locked retrograde nail].

Introduction: Charcot's arthropathy is a disabling non-infectious, progressive condition characterized by bony and articular destruction in patients with sensory neuropathy. In advanced cases with deformities and ankle instability, it requires a more invasive treatment as an ankle fusion with a retrograde locked intramedullary nail. It is unknown if, in these patients, the functional results of AOFAS (American Orthopaedic Foot and Ankle Society) correlate with the quality of life ones from the EuroQol-5D test and the possible postoperative complications.

Material And Methods: the design is experimental, longitudinal prospective with ambispective data analysis (retrospective and prospective) to evaluate the functional results and life quality with a year of following patients with Charcot's arthropathy diagnosis treated with a retrograde locked nail from January 1, 2010, to November 1, 2018.

Results: this study resulted in complete consolidation from nine out of 11 cases, with a success rate of 81.2%, and only two cases (18.2%) developed nonunion. AOFAS and EuroQol-5D tests correlate positively in agreement with the Pearson correlation.

Conclusions: AOFAS and EuroQol-5D correlate positively, having a 45 and 63% of acceptable and satisfactory results, respectively, for both tests.
