We report a prospective single-blind controlled
study of the incidence of early wound infection after internal fixation for
trauma in 609 patients, of whom 132 were HIV-positive. Wounds were
assessed for healing using the ASEPSIS score. There was no significant
difference in the rate of infection between HIV-positive and HIV-negative
patients undergoing clean surgery (4.2% vs 6%,
respectively; p = 0.65). HIV-positive patients did not receive additional antibiotic
prophylaxis or antiretroviral therapy as part of their management.
The difference in the rate of infection between HIV-positive and
HIV-negative patients with an open fracture or other contamination
was not significant (33% vs 15%, respectively;
p = 0.064). There was no relationship between CD4 count and infection
rate. HIV status did not significantly influence the number of secondary
surgical procedures (p = 0.183) or the likelihood of developing
chronic osteomyelitis (p = 0.131). Although previous contamination
from the time of injury was a risk factor for infection in mal-
and nonunions, it was not significantly increased in HIV-positive
patients (p = 0.144).
We conclude that clean implant surgery in HIV-positive patients
is safe, with no need for additional prophylaxis.
