Shoulder Dislocation Incidence and Risk Factors—Rural vs. Urban Populations of Poland

Abstract

(1) Background: The aim of this study was to analyze the incidence of shoulder dislocation and to estimate non-modifiable risk factors in rural and urban subgroups in Poland. (2) Methods: The study covered the entire Polish population, divided into urban and rural subgroups and observed between 1 January 2014 and 31 December 2014. The study population consisted of Polish patients with a diagnosis of shoulder dislocation (S43.0) in accordance with the International Statistical Classification of Diseases and Related Health Problems (ICD-10). Records were obtained from the public health care provider National Health Found (Narodowy Fundusz Zdrowia, NFZ). Based on these data, we assessed shoulder dislocation incidence and risk rates, stratifying the study sample by sex, age and place of residence (rural or urban) using the Central Statistical Office (GUS) personal territorial code (TERYT). (3) The incidence was 25.97/100,000 person-years in rural areas and 25.62/100,000 person-years in urban areas. We did not find significant differences in the incidence between the two subgroups. The highest incidence (75.12/100,000 person-years) and the highest risk for shoulder dislocation were found among subjects 80+ years old living in urban areas. Furthermore, men in the third decade of their life living in urban areas showed the highest risk (OR = 7.8, 95% CI; 6.44–9.45, p < 0.001). In both subgroups, the likelihood of shoulder dislocation was significantly lower for the female sex and among children ≤9 years old. However, girls living in rural areas presented with a significantly higher likelihood for dislocation compared with their peers living in urban environments. (4) Conclusions: No significant difference in the incidence rate of shoulder dislocation between Polish residents living in rural and urban areas emerged. The highest incidence was observed among female subjects 80+ years old living in urban environments. The highest risk was found among men in the third decade of their life living in urban areas. In addition, girls in the first decade of their life living in rural areas had more shoulder dislocations than girls living in urban environments. Shoulder dislocation is dominant in female subjects aged 70–79 living in rural areas and in females 80+ years old living in urban areas.

Epidemiology of Shoulder Dislocation Treated at Emergency Departments in the United States Between 1997 and 2021

“…Previous studies have shown similar but slightly lower rates of sports-related shoulder dislocations. 10 , 13 , 19 , 21 , 23 Men are more likely to dislocate their shoulders playing sports than women, who are more likely to dislocate their shoulders during nonsports-related activities.…”

“…3,4,5,15,22,23 Previous studies have estimated that the incidence of shoulder dislocations is 11.2 to 49.5 per 100,000 person-years in the United States (US) and 15.3 to 56.3 per 100,000 person-years in other countries. 2,6,9,10,16,19,22,23 The data suggest that men are more likely than women to dislocate the shoulder, and dislocations occur in a bimodal age distribution with younger and older groups at most risk. 9,10,16,22,23 The frequency and characteristics of sports-related dislocations in the general population have been studied; nonetheless, its trend over time has yet to be reported.…”

The Role of Platelet-Rich Plasma on the Chondrogenic and Osteogenic Differentiation of Human Amniotic-Fluid-Derived Stem Cells

“…In recent decades, the use of PRP has gained popularity in the field of tissue engineering because of its anti-inflammatory and analgesic properties, as well as its capacity to induce neo-angiogenesis, tissue formation, and remodeling by influencing stem-cell migration, proliferation, and differentiation [ 14 ]. Because of these properties, the clinical use of PRP in the orthopedic field has increased more and more, with it finding an application with encouraging results in the most common orthopedic pathologies, such as muscle lesions, acute and chronic tendinitis, mild osteoarthritis, and osteochondral lesions [ 7 , 8 , 9 , 10 , 11 , 12 ].…”

“…Because of all these characteristics, PRP has found wide application in clinical practice, useable as local infiltration in many orthopedic diseases, such as as mild osteoarthritis, acute and chronic tendinitis, and plantar fasciitis, as well as in pathologies that are not strictly orthopedic, such as the treatment of chronic wounds and diabetic ulcers, and it has even found application in other fields of medicine, such as plastic surgery and medical esthetics [ 7 , 8 , 9 , 10 , 11 , 12 ].…”

Performance of the Fresno-Quebec Rule in identifying patients with concomitant fractures not requiring a radiograph before shoulder dislocation reduction: a multicenter retrospective cohort study

“…Shoulder dislocation is a common reason for emergency department (ED) consultation and its incidence rate has been estimated to be approximately 23/100 000 person-years in Europe and North America [1][2][3][4][5]. More specifically, antero-inferior glenohumeral dislocation is the most frequent type (up to 97% of cases) and mostly affects young male adults and older females [1][2][3][4]6].…”
