Manganese and iron are elements that constitute components of bone tissue. The aim of this study was to determine presence of manganese and iron in hip joint tissue and interdependencies between these elements. The objects of the research were hip joint elements from people residing in cities on the territory of the Upper Silesian Industrial District. The number of people in the study group was 91 samples, including 66 samples from women and 25 from a man. The examined tissues were obtained intraoperatively during hip replacement procedures. The content of manganese and iron was determined using the atomic absorption spectrophotometry (AAS) method. The lowest content of manganese and iron was found in the cortical bone, and the largest, in the case of manganese, in the articular cartilage, whereas in the case of iron in a fragment of the cancellous bone from the intertrochanteric area. The content of iron in selected elements of the hip joint decreased with age. Higher content of manganese in hip joint tissue of women compared to men was confirmed. What is more, higher content of iron in hip joint tissue of men was confirmed as well.
锰和铁是构成骨组织成分的元素。本研究的目的是确定髋关节组织中锰和铁的存在及其相互关系。研究对象为上西里西亚工业区城市居民的髋关节组织。研究组人数为 91 例样本，其中 66 例来自女性，25 例来自男性。研究中使用的组织是在髋关节置换手术过程中获得的。锰和铁的含量是使用原子吸收分光光度法（AAS）确定的。锰和铁含量最低的是皮质骨，锰含量最高的是关节软骨，而铁含量最高的是股骨转子间区域的松质骨碎片。髋关节各部位铁的含量随年龄增长而降低。研究证实，女性髋关节组织中的锰含量高于男性。此外，还证实了男性髋关节组织中铁含量较高。
