The treatment of charcot neuroarthropathy of the hindfoot often leads to amputation after unsuccessful attempts of conservative and surgical treatment.1,6,7 Despite highly advanced exoprothetics after amputation, when compared to successfully fused hindfoot, looks less functionally efficient in terms of ambulation and energy expenditure, resulting in excessive cardiac strain.8 Hindfoot fusion using a tibiotalocalcaneal nail can be a valid option before considering amputation. Therefore, the amputation and exoprothetics should exclusively be reserved for the non-reconstructable foot. For charcot arthropathy there are numerous different arthrodesis techniques with screws, plate osteosynthesis and external fixators described in the literature.1,6 The correction of bony deformity, a stable intraosseous fixation, the locking function as well as the ability of compression are the perquisites for the bony union in hindfoot arthrodesis.1
Retrograde tibiotalocalcaneal compression nail often provides a robust hindfoot capable of pain- free full weightbearing avoiding secondary dislocation and implant failure. Hindfoot fusion with a retrograde tibiotalocalcaneal nail is of great value in advanced stage of chracot neuroarthropathy and is therefore an effective operative...
