Background. About 40 % of patients diagnosed with coxarthrosis annually seek medical help and receive social support due to this disease. Increased use of an expensive surgery for treatment of coxarthrosis and projected growth of its prevalence in the population determine the relevance of socio-economic analysis.The aim of the study. To assess the value and structure of economic damage caused by the delivering health and social care to patients with coxarthrosis at the state level of the Russian Federation.Methods. To assess economic damage, we used the average annual number of various categories of patients and disabled people with coxarthrosis in the Irkutsk region for 2008–2017. Three main categories were identified: patients who visited the outpatients’ clinic; patients with total hip replacement; disabled people due to coxarthrosis. For each category, we calculated weighted average damage per 1 conventional patient, taking into account direct and indirect costs and subsequent multiplication by the average annual number of individual categories of patients. Calculations were performed in 2017 prices.Results. The average annual socio-economic damage from coxarthrosis amounted to 1.39 (1.34÷1.43) billion rubles or 0.1 % of the gross regional product. The most of the damage (64.4 %) were indirect costs associated with disability due to coxarthrosis, 22.2 % of the total amount were the costs of hip replacement surgery, 13.4 % were the costs of outpatient visits. Indirect economic losses due to disability in patients of working age were 4.2 times higher than losses due to disability of oldage pensioners.Conclusion. The results of the study confirm the economic feasibility of surgical treatment of coxarthrosis, especially in patients of working age.

Background. Coxarthrosis prevalence rates are necessary to assess the socio-economic significance of this pathology and to calculate the need for endoprosthetics. Information about the provision of medical care to patients with coxarthrosis is presented in the reports of various medical organizations, but in state statistical reports at the regional level this nosological form is not taken into account as a separate line.The aim. To estimate the prevalence of coxarthrosis based on the combined use of medical records from various sources in a region with a specialized clinic for prosthetics of large joints.Materials and methods. A retrospective descriptive epidemiological study based on materials from the Irkutsk region for 10 years (2008–2017) was carried out. Three main sources of data on patients with coxarthrosis were used: continuous and randomized samples based on population visits to polyclinics (n = 24 029), information from the bureau of medical and social expertise on disability (n = 19 081) and information from a specialized clinic on total hip arthroplasty (THAP) (n = 6227). The dynamics of indicators by years, the distribution of patients by sex, age and groups of disabilities have been analyzed. Regional indicators of incidence and prevalence of coxarthrosis were calculated based on extrapolation of sample data.Results. The following average annual regional indicators for patients with coxarthrosis were calculated: primary visits to polyclinics (incidence) – 73.8 (71.9–75.7) with a frequency of visits 1.9 times a year, the frequency of THAP operations – 3,3 (3,0÷3,6), disability – 10.1 (10.0÷10.3). The median age of patients at the initial visit was 61 years (Q1 = 46; Q3 = 76). The proportion of men among different groups of patients ranged from 41 to 44%, the proportion of disabled people among patients of the polyclinic and surgical hospital – from 45.2 to 47.1%. The estimated prevalence of coxarthrosis among the adult population was 413.5 (410,6÷416,4) / 10000.Conclusions. The epidemiological analysis algorithm described in the article is proposed as the first stage in assessing the social and economic significance of coxarthrosis and the regional need for arthroplasty of large joints.

The prevalence of coxarthrosis in Ust-Ordynsk Buryat Region was defined as 19,8 ‰0 This article gives complex characteristics of coxarthrosis in the named region.

The article presents the results of research of femoral head morphology at the III-IV stage of coxarthrosis. Tissue reorganization in femoral head is shown.

Coxarthorosis is a degenerative-dystrophic disorder affecting all layers of population with increasing sickness rate among adult people. Coxarthoris is characterized by steadily progressive course leading patients to disability without ability of self-service. Closer attention of all kinds of medical workers is necessary in diagnostics and. rendering of all kinds of assistance available for this category of patients: not only qualified, medical attention, but also help in social rehabilitation.
