Background: The intramedullary insertion of antibiotic-impregnated cement beads is used widely for the treatment of intramedullary infection. This report describes an improved technique for removing chains of antibiotic beads inserted into the intramedullary cavity. %26lt;br%26gt;Methods: We examined four cases in three patients of the intramedullary insertion of chains of antibiotic-impregnated cement beads for the treatment of osteomyelitis of the diaphysis of the tibia after the fixation of fractures with interlocking nails. During bead removal, the tip of an intramedullary guidewire was bent into a hook shape and was then engaged with the chain of impacted beads. The guidewire was removed from the intramedullary cavity, permitting the extraction of any beads adhering to the wire. %26lt;br%26gt;Results: As beads came into contact with the tip of the intramedullary guidewire, they could be extracted easily. No additional incision or bone fenestration was required. %26lt;br%26gt;Conclusions: The use of a hook-shaped intramedullary guidewire simplifies the removal of chains of antibiotic-impregnated cement beads without the need for an invasive procedure. This technique makes the use of chains of cement beads a favorable choice for treating intramedullary infection.
