PurposeTo determine the rate of postoperative wound infection and the association with prophylactic antibiotic use in uncomplicated carpal tunnel release surgery.MethodsWe performed a multicenter, retrospective review of all the carpal tunnel release procedures performed between January 1, 2005, and August 30, 2007. Data reviewed included the use of prophylactic antibiotics, diabetic status, and the occurrence of postoperative wound infection. We determined the overall antibiotic usage rate and analyzed the correlation between antibiotic use and the development of postoperative wound infection.ResultsThe rate of surgical site infections in the 3003 patients who underwent carpal tunnel release surgery (group A) was 11. Antibiotic usage data were available for 2336 patients (group B). Six patients without prophylactic antibiotics had infection, as did 5 patients with prophylactic antibiotics. This difference was not statistically significant. Of the 11 surgical site infections, 4 were deep (organ/space) and 7 superficial (incisional). The number of patients with diabetes in the overall study population was 546, 3 of whom had infections. This was not statistically different from the nondiabetic population infection rate (8 patients).ConclusionsThe overall infection rate after carpal tunnel release surgery is low. In addition, the deep (organ/space) infection rate is much lower than previously reported. Antibiotic use did not decrease the risk of infection in this study population, including patients with diabetes. The routine use of antibiotic prophylaxis in carpal tunnel release surgery is not indicated. Surgeons should carefully consider the risks and benefits of routinely using prophylactic antibiotics in carpal tunnel release surgery.Type Of Study/Level Of EvidenceTherapeutic III.Copyright 2010.
