Bone metabolism and the trace element content associated with it change at each stage of degenerative disease. The aim of this study was to find out about the role of the analyzed elements in different stages of hip osteoarthritis. Elements associated with oxidative and enzymatic processes were analyzed depending on the changes in the radiological images of the hip joint. Element content analysis was performed by the inductively coupled plasma mass spectrometry analytical technique. The femoral head in severely osteoarthritic hips (KL3-4) compared to mild grade osteoarthritis (KL2) had a greater content of Cu (median 1.04 vs. 0.04), Sr (median 38.71 vs. 29.59), and Zn (median 75.12 vs. 63.21). There were no significant differences in the content of Mo, Cr, and Fe in the femoral head and neck between the groups. The Cu/Fe correlation was negative in the KL2 group (-0.47) and positive in the KL3-4 groups (0.45). Changes in the content and correlation of trace elements in the hip joint explain the changes in metabolism dependent on the severity of degenerative changes.
在退行性疾病的每个阶段,骨代谢及其相关的微量元素含量都会发生变化。本研究的目的是了解所分析元素在髋关节骨关节炎不同阶段的作用。根据髋关节的放射影像变化,分析了与氧化和酶促过程相关的元素。采用电感耦合等离子体质谱分析技术进行元素含量分析。与轻度骨关节炎(KL2)相比,重度骨关节炎髋关节(KL3 - 4)的股骨头中铜(中位数1.04对0.04)、锶(中位数38.71对29.59)和锌(中位数75.12对63.21)的含量更高。两组之间股骨头和颈部的钼、铬和铁含量没有显著差异。在KL2组中铜/铁相关性为负(-0.47),而在KL3 - 4组中为正(0.45)。髋关节中微量元素含量和相关性的变化解释了依赖于退行性变化严重程度的代谢变化。
