Assessment of surgical site infection when using postoperative antibiotic prophylaxis in subtalar fusion surgery 24hours versus 5 days

Infection in orthopedic surgery is one of the most dreaded complications. Antibiotic prophylaxis should be utilized routinely in foot and ankle surgeries involving bone, utilizing hardware and prosthetic joints.

The controversy persists in administration of antibiotics varying from a single dose to 3 doses to 5 days or 14 days. In subtropical country, with a hot and humid climate is a conducive environment for both Gram-positive and Gram-negative bacterial colonization of skin. Therefore, we need studies tailored to our environment in Egypt Prevention of SSIs is critical for the health of patients, Economic efficiency, Antibiotic resistance considerations In conclusion, in many ways, the topic of prophylactic antibiotics in elective foot and ankle surgery is an unusual one, in that a relative divide exists between empirical science and common practice.
