Abstract

Infectious complications during endoprosthesis of large joints are one of the urgent medical and socio-economic problems of modern orthopedics and traumatology. The purpose of the study was to improve the results of treatment of periprosthetic infection in patients after total hip arthroplasty as a result of polytrauma by determining the features of the course and diagnosing it in this category of patients. To carry out the study, a retrospective analysis of 87 cases of periprosthetic infection was conducted in patients undergoing inpatient treatment at the Kyiv City Clinical Hospital of Emergency Medical Care for the period 2012–2020 and divided into observation and control groups. Іn the first group, acute postoperative periprosthetic infection (up to 4 weeks) was detected in 33 victims, which was 71.7% of the group. In the second group, this type of periprosthetic infection was detected in 23 victims, which was 56.1% of the group. Late chronic infection (from 4 weeks to 1 year) among the victims of the first group was found in 10 patients, which was 21.7% of the group. In the second group, there were 11 patients with late periprosthetic infection, which was 24.4% of the group. All patients participating in the study were divided into observation and control groups. Periprosthetic infection after total hip arthroplasty in polytrauma victims develops more often in the early stages, up to 4 weeks. In addition to gram-positive cocci, the causes of periprosthetic infection are often gram-negative enterobacteria, which indicates the prevalence of the endogenous route of infection in this category of patients. Among the etiological factors of periprosthetic infection after total hip arthroplasty in polytrauma victims, Acinetobacter spp. is quite often found, which is a consequence of long-term use of invasive methods of treatment and monitoring performed on the patient during the treatment of traumatic injuries. Keywords: large joints, arthroplasty, microorganisms, complications, multiple trauma.
