Background: Three main diagnostic types of osteoarthritic changes are distinguished in clinical and anthropological literature: osteophytes, porosity, and eburnation. The nature of the relationship between these changes and how lesions progress over time is still unclear.

Aim: The aim of the present study is the analysis of the relationships between osteophytes, porosity, and eburnation based on skeletal material.

Subjects and methods: The analysis employed the skeletal collection from Cedynia (199 individuals) from tenth to fourteenth-century Poland. Marginal osteophytes (OP), porosity (POR), and eburnation (EB) were examined on a shoulder, elbow, wrist, hip, knee, and ankle.

Results: Osteophytes and porosity occurred independently of each other. Combinations of osteophytes and porosity (OP + POR) and osteophytes, porosity, and eburnation (OP + POR + EB) were rarely observed. Combinations of osteophytes and eburnation (OP + EB) or porosity and eburnation (POR + EB) were not found. There was a significant correlation between osteophytes and porosity in the scapula, proximal end of the ulna and proximal end of the femur. Osteophytes and eburnation were correlated at the distal end of the ulna. Porosity and eburnation were correlated at the distal end of the radius and distal end of the ulna. When all joints were considered together, all the types of osteoarthritic changes were correlated. However, the relationship between osteophytes and eburnation and between porosity and eburnation was only slightly significant. Osteophytes preceded porosity, but there were a few cases where more developed porosity accompanied less developed osteophytes.

Conclusions: The findings indicate that correlations between osteoarthritic changes are weak, albeit statistically significant and further studies of the relationship between changes are necessary.

背景：骨关节炎变化的三种主要诊断类型在临床和人类学文献中有所区别：骨赘，孔隙度和烧伤。这些变化与病变随时间的进展之间关系的性质尚不清楚。

目的：本研究的目的是基于骨骼材料分析骨赘，孔隙度和灼烧之间的关系。

受试者和方法：分析采用了十世纪至十四世纪波兰Cedynia（199个人）的骨骼收藏。在肩膀，肘部，腕部，臀部，膝盖和脚踝处检查边缘骨赘（OP），孔隙率（POR）和发芽（EB）。

结果：骨赘和孔隙彼此独立发生。很少观察到骨赘和孔隙度（OP + POR）的组合，以及骨赘，孔隙率和发烧（OP + POR + EB）的组合。没有发现骨赘和发烧（OP + EB）或孔隙率和发烧（POR + EB）的组合。肩phy骨，尺骨近端和股骨近端骨赘与孔隙率之间存在显着相关性。骨赘与尺骨远端的烧伤相关。the骨的远端和尺骨的远端之间的孔隙率和烧伤相关。当所有关节都一起考虑时，所有类型的骨关节炎变化都相关。然而，骨赘与灼烧之间的关系以及孔隙率与灼烧之间的关系仅略显着。

结论：研究结果表明，骨关节炎变化之间的相关性较弱，尽管具有统计学意义，并且有必要进一步研究这些变化之间的关系。
