Abstract
Background
Growing of the geriatric population has brought about increase of lower extremity fractures. The purpose of this study was to investigate the occurrence of surgical site infection after the surgery for lower extremity fractures, except proximal femoral fracture, in over eighty years old patients.
Methods
Patients with closed lower extremity fracture which were treated surgically in 2011 were divided into two groups (Group O; the equal or more than 80 years old, Group Y; from 20 to 65 years old), and the incidence of infection and the outcome after its treatment was compared between Group O and Group Y.
Results
In group O, there were 35 fractures in 35 patients with average age of 86.7 years (range from 80 to 92). Five patients (14.3%) showed infection. Only one case recovered from infection, one died because of sepsis and the other three required amputation. The reasons for amputation were advanced sepsis in 2 and severe soft tissue damage in 1. In group Y with 110 fractures in 101 patients, there was no infection (p = 0.0007).
Conclusions
The presented study showed that infection rate following lower extremity fracture surgery in group O had been significantly higher than that of group Y. Despite the application of minimum invasive surgery or intramedullary nail, infection occurred in Group O. Once, infection occurred after lower extremity fracture surgery in advanced age patients, it may be difficult to recover the infection without amputation.
