Reconstruction of unstable ankle charcot deformity using a 3-D printed titanium porous block and hindfoot nail – A case report.

Charcot neuroarthropathy (CN) of the ankle joint can cause marked bone resorption of the talus resulting in severe deformity and instability. The utilisation of a 3-D printed bespoke titanium porous block that allows the use of an intramedullary calcaneo-tibial nail is an attractive option in such cases that has been reported for use in post-trauma deformities, following tumour resections, in avascular necrosis of talus and for revision of failed total ankle replacements, however has not previously been reported for Charcot ankle reconstructions. We present a novel case and surgical technique illustrating the use of a 3-D printed titanium porous block and hindfoot nail for reconstruction of a deformed and unstable Charcot hindfoot. • Charcot neuroarthropathy (CN) of the ankle joint can cause marked bone resorption of the talus. • Charcot neuroarthropathy (CN) of the ankle joint can therefore result in severe deformity and instability. • 3-D printed bespoke titanium porous blocks with an intramedullary calcaneo-tibial nail can be used in such cases. • We present a novel case and surgical technique illustrating this strategy for complex Charcot hindfoot reconstruction.
