Four Cases with Rare Complications of Intramedullary Screw Fixation for Jones Fracture.

Active treatment with intramedullary screw fixation is now common for athletes with Jones fracture. Outcomes are generally good, but complications can occur. We report 4 rare complications of intramedullary screw fixa-tion. Two cases developed osteomyelitis and pseudarthrosis caused by thermal necrosis. In the other two cases, screw-related complications occurred during the insertion of the tapered headless screw. Although thermal necrosis and screw insertion failures are considered rare complications and not widely reported in the litera-ture, they do occur occasionally. Knowing the mechanisms underlying these complications could help prevent them, and knowing their course could lead caregivers to appropriate interventions when they do occur.
