Summary

Polymethylmethacrylate antibiotic beads effectively treat bone infections and open fractures. Removal is not always necessary, as most patients experience no long-term complications without bead removal.

Orthopedic Surgery
Infectious Diseases
Biomaterials Science

Background:

Polymethylmethacrylate (PMMA) antibiotic beads are used for chronic osteomyelitis and open fractures.
The necessity of removing these beads to prevent long-term complications is not well-established.

Purpose of the Study:

To investigate whether antibiotic bead removal is required to avoid long-term adverse events.

Main Methods:

Retrospective chart review of patients with extremity or pelvis fractures treated with PMMA antibiotic beads.
Study period spanned five years.

Main Results:

Fifty-one patients met inclusion criteria.
A significant majority (73%) experienced no complications, even without bead removal.

Conclusions:

PMMA antibiotic beads are effective for delivering high-dose local antibiotics.
Routine removal of these beads may not be necessary for all patients.
