Abstract
PURPOSE: Secondary displacement of traumatic ankle fractures with subsequent soft-tissue breakdown is a troublesome issue after inappropriate conservative treatment among non-compliant diabetic patients with severe peripheral neuropathy. This study was conducted to evaluate the results of a less-invasive arthrodesis procedure as an alternative to osteosynthesis in these complex scenarios. METHODS: A total of 46 diabetics, who underwent fluoroscopy-assisted trans-calcaneal retrograde nailing-based ankle arthrodesis between 2012 and 2018 for salvaging secondary-displaced diabetic ankle fractures in their insensate feet, were evaluated in this retrospective study. All fractures were associated with uninfected mechanical ulcers overlying malleoli, without Charcot changes, after failed conservative cast immobilization. The patients (mean age: 52.52 ± 3.70 years; 18 males; 46 feet) were evaluated radiologically for union and clinically for limb salvage, modified American Orthopedic Ankle and Foot Scale (AOAFS), and the overall subjective patients' satisfaction. RESULTS: The mean follow-up was 29.5 ± 3.1 months. All ulcers have healed with local care only with 100% limb salvage. Four patients experienced minor wound healing problems at posterior heel, and another one developed acute Charcot changes that was successfully managed by offloading and repeat surgery. Forty patients (86.96%) had fully consolidated fusions with a mean time to fusion 15.78 ± 2.58 weeks, while the other six cases had stable fibrous-union. At the final follow-up, the mean modified-AOFAS was 76.85 ± 6.0 from 86 total points. All, but four patients (91.30%) were completely satisfied while the other four patients were partially satisfied. CONCLUSIONS: The presented less-invasive arthrodesis technique is reproducible and effective alternative for salvaging unstable diabetic ankle fractures in the insensate feet when standard surgical procedures would be more risky. LEVEL OF EVIDENCE: IV, retrospective case series.
