Complete ejection of a ring sequestrum 8 years after external fixation of the tibia. On the day of scheduled debridement for a persistent pin tract infection, a 23-year old man presented himself carrying a small bony ring sequestrum that had spontaneously ejected from his tibial wound 1 week earlier. Eight years prior to presentation, he was treated for an open crural fracture which was stabilised with an external fixator. Revision of the operation notes revealed that the placement of this external fixator was performed without predrilling.
