Experience in the treatment of patients with nonspecific coxitis using two-stage endoprosthetics

Relevance. One of the rare pathologies of the hip joint is its inflammation caused by nonspecific microflora. The literature often indicates the complexity of the diagnosis and treatment of this condition. Emerging irreversible changes in the joint require radical intervention. The aim of the study was to evaluate the effectiveness of one of the treatment options in the form of two-stage arthroplasty with the installation of an articulating spacer at the first stage, with a demonstration of clinical examples. Materials and methods. The article describes the experience of treating 18 patients with two-stage arthroplasty (19 cases, including one patient with a bilateral process). All patients underwent the installation of articulating spacers with antibiotics of various configurations using both prosthetic components and those made manually. The second stage was performed in 15 patients after 121 ± 21.1 days. Results. An improvement in the functional state of the affected hip joint by the time of the second stage of treatment was noted (from 19.1 ± 2.6 to 30.5 ± 5.6 points on the Harris scale). The second step was the installation of a total arthroplasty of cementless (n = 11) or hybrid (n = 4) fixation. At the long-term follow-up, 35.2 ± 6.1 months. in 86.7% of cases, eradication of the infectious process was noted; Harris average functional result 82.2 ± 4.0 points. Conclusions. Thus, the use of two-stage arthroplasty in the treatment of nonspecific coxitis can achieve satisfactory results.
