Objective : Pin-site infection is one of the most troublesome complications of external fixation. The present study aimed to
compare the rate of pin-site infection following silver sulfadiazine with dry dressing.
Material and Method: This was a prospective randomized controlled study among 30 clients that compared the outcome of
pin dressing using silver sulfadiazine (study group = 15) with dry dressing (control = 15). All eligible subjects of open tibial
fracture had an emergency debridement with external fixation. Pin tract infection was considered to be present if superficial
inflammation (erythema, cellulitis), serous or purulent discharge occurred around a pin site and deep infection of osteolysis
around the pin, and sequestrum.
Results : Seven subjects (46.7%) had pin-site infection in the present study group while six subjects (40.0%) had it in the
control group, with comparable severity.
Conclusion : There was no significant difference in prevalence of pin-site infection between both groups (p = 0.97). Therefore,
either silver sulfadiazine or dry dressing could be advocated.
