Corneal Subbasal Nerve Plexus Changes in Severe Diabetic Charcot Foot Deformity: A Pilot Study in Search for a DNOAP Biomarker

Figure 1

Radiologic case series of a 56-year-old male patient with IDDM for 19 years and severe midfoot Charcot arthropathy-type Sanders/Frykberg II/III on the left foot, with subluxation in the talocalcaneal and talonavicular joints. Initial diagnosis made in October 2013 after trivial distortion of the upper ankle joint (a–c) bearing radiographs in lateral, anterior-posterior, and oblique views. Intra- and extramedullary implants were used for reconstructive arthrodesis of the medial and lateral midfoot columns (d–f). Radiographs 6 months after surgery reveal a loss of reduction and implant breakage, displaying a frequent problem in Charcot surgery (g–i).
