Osteoarthritis: A problematic disease in past human populations. A dependence between entheseal changes, body size, age, sex, and osteoarthritic changes development

Abstract

Osteoarthritis is a problematic trait in terms of etiology and interpretation in past human populations. The relationships between osteoarthritic changes (osteophytes, porosity, and eburnation) and entheseal changes, body mass, stature, bone massiveness, sex, and age on the basis of skeletal material from Łekno (Poland) are analyzed here. Entheses were the strongest contributor to the prediction of osteophyte expression and when all types of changes and all joints were taken together. Stature demonstrates a negative dependence on porosity. When each joint was analyzed separately, entheses were the strongest contributor to the prediction of arthritis expression in the wrist and hip. Age was the strongest contributor to the prediction of arthritis expression in the elbow. Body mass, stature, bone massiveness, and sex had no effect on osteoarthritic changes in any of the examined joints. The results of the present study suggest an important dependence between entheses and osteoarthritic changes. Other factors had little to no effect on differences in OA severity. These results do not dispel all doubts but enrich knowledge about the effect of etiological factors on osteoarthritic change formation. This knowledge is essential for proper, reliable interpretation of osteoarthritic changes in the context of past human biology, ecology, and behavior.

Beyond dirty teeth: Integrating dental calculus studies with osteoarchaeological parameters

“…This issue is linked to the fact that different activities may generate similar functional stresses and these stresses may affect differently specific individuals ( Jurmain et al, 2012 ). In addition, entheseal changes and osteoarthritis are multifactorial in etiology, with age and body size generally playing a more important role in their expression compared to activity ( Michopoulou et al, 2015 ; Myszka et al, 2020 , but see Karakostis et al, 2017 , 2019 ).…”

The emerging role of exosomes in innate immunity, diagnosis and therapy

“…It is an umbrella term for several diseases, such as rheumatoid arthritis and osteoarthritis. Osteoarthritis is a degenerative disease that damages the synovial joints of the hands, feet, knees, and hips, which in many instances, are disabled ( 105 – 108 ). The different tissues around the joints have various effects on the pathology of osteoarthritis, especially inflammatory cytokines from the synovial fibroblasts of inflammatory cells.…”

“Brothers in arms”: Activity‐related skeletal changes observed on the humerus of individuals buried with and without weapons from the 10th‐century CE Carpathian Basin

“…Activity‐related skeletal changes include qualitative and quantitative features, such as entheseal changes (at the insertion sites of tendons and ligaments), joint changes, and bone geometry (e.g., cross‐sectional geometry), which are the most frequently studied parameters (Alves Cardoso & Henderson, 2010; Niinimäki, 2012; Nikita, 2017; Myszka, Krenz‐Niedbała, et al, 2019). In the last few decades, numerous studies focused on the analysis of changes related to general or specific activities (e.g., Alves Cardoso & Henderson, 2013; Berthon et al, 2019; Djukic, Miladinovic‐Radmilovic, Draskovic, & Djuric, 2018; Dutour, 1986; Hawkey & Merbs, 1995; Henderson, Mariotti, Pany‐Kucera, Villotte, & Wilczak, 2016; Kennedy, 1989; Mariotti, Facchini, & Belcastro, 2004; Mariotti, Facchini, & Belcastro, 2007; Pálfi & Dutour, 1996; Rhodes & Knüsel, 2005; Robb, 1998; Ryan, Desideri, & Besse, 2018; Stirland, 1998; Thomas, 2014; Villotte, 2006; Villotte et al, 2010; Wilczak, 1998).…”
