OBJECTIVES: Treatment of tibial fractures with Ilizarov external fixation is a valuable treatment alternative; however, development of problems at the pin site is one of the major drawbacks of this technique. Moreover, there is no general agreement regarding pin site care. The purpose of this study was to compare the efficacy of two different pin site care techniques after treatment of tibial fractures with an Ilizarov external fixator. DESIGN: Prospective randomized study. SETTING: Department of Orthopaedic Surgery of education and research hospital. PATIENTS AND METHODS: In this prospective randomized study, we followed up 610 pin sites in 39 cases using two different pin site care protocols. INTERVENTION: For the first 15 days, patients in both groups cleaned each pin site using sterile gauze impregnated with 10% polyvinylpyrrolidone iodine (Polyod) every 3 days. After 15 days, patients in group 1 (20 cases, 310 pin sites) were advised to perform pin care by daily showering and brushing the pin sites with soap and an ordinary soft toothbrush, whereas patients in group 2 (19 cases, 300 pin sites) were advised to perform pin care by daily showering and cleaning the crusts using sterile gauze impregnated with 10% polyvinylpyrrolidone iodine (Polyod). Each pin site was denominated according to location. MAIN OUTCOME MEASUREMENTS: Pin sites were inspected and graded on a scale of 0 to 5 according to slight modification of the system of Dahl described by Gordon et al during outpatient visits on the 5th, 10th, 15th, 30th, 45th, 60th, 75th, 90th, 120th, and 150th days of follow up after the operation until fixator removal. Grade 1 and grade 2 infections were categorized as minor infection not requiring any extra pin site care and grade 3 and above infections as major infection. RESULTS:Minor infection rate of all pin sites was determined as 50.7% in group 1 and 43.6% in group 2. Major infection rate was determined as 3.5% in group 1 and 3.7% in group 2. No statistically significant difference was noted between the two groups (all P > 0.05). CONCLUSION: Pin site care can be performed without impairing patient comfort and without prohibition of showering. Pin site care can be self-managed by the patients without complex sterilization techniques.
