Schantz pin placement in the calcaneal tuberosity is a common procedure known to be complicated by pin site infections and nerve injuries. Fractures through Schantz pin sites has been reported mostly in diaphyseal bone. This case series highlights three patients with type 2 diabetes mellitus and diabetic neuropathy who were fixed in an external fixator frame with a pin through the calcaneal tuberosity. At an average of 13 weeks, the patients presented with fracture through the pin site at the calcaneal tuberosity. One patient was treated with open reduction and internal fixation of the calcaneus and two patients were treated nonoperatively. These cases suggest that placement of calcaneal pins in patients with diabetic neuropathy harbors risk of iatrogenic fracture, a complication that has not been reported in the literature.
将斯氏针置于跟骨结节是一种常见的手术，已知会因针道感染和神经损伤而变得复杂。斯氏针针道处骨折大多报道于骨干骨。本病例系列突出了三名患有2型糖尿病和糖尿病性神经病变的患者，他们通过一枚穿过跟骨结节的针固定于外固定架。平均13周时，患者出现跟骨结节处针道骨折。一名患者接受了跟骨切开复位内固定治疗，两名患者接受了非手术治疗。这些病例提示，在患有糖尿病性神经病变的患者中置入跟骨针存在医源性骨折风险，这是一种文献中尚未报道的并发症。
