RESUMO
Diabetic calcaneal insufficiency avulsion (CIA) fracture are unusual injury. The treatment may be challenging due to the low healing potential from diabetes or Charcot neuroarthropathy, so far. The poor surgical outcomes and surgical failures from treatment of the traumatic calcaneal avulsion fractures were associated with poor bone stock, lack of proper fixation, and the wound problem. Thus, the proper treatment for diabetic CIA fracture was still controversy. This report described two cases of diabetic CIA fracture treated with fixation of fracture fragment and calcaneal tenodesis. In both cases, fracture fragments were re-avulsed despite of fixation. Through investigation for the fate of fracture fragment from these cases, we discussed the proper treatment strategy in diabetic CIA fracture.
