Long-term implantation of gentamicin-polymethylmethacrylate antibiotic beads

Henry SL. Hood GA. Seligson D. Clinical Orthopaedics & Related Research. (295):47-53, 1993 Oct. Fifty-two chronic osteomyelitis patients treated with gentamicin-polymethylmethacrylate (Septopal) antibiotic bead chains were observed retrospectively to explore the relationship between the duration of bead implantation and clinical results. Group A contained 35 asymptomatic patients who had elective bead removal based on protocol, surgeon's preference, and patient variables. Group B consisted of 17 patients who retained the antibiotic beads. The presence or absence of redness, abscess, drainage, pain, or swelling at the wound site was documented for clinical evaluation. Findings indicate that Septopal bead chain implants exhibit higher success (remission) rates with increasing length of duration without increasing the risk of complications.
