The aim of this study was to determine the distribution of magnesium, calcium, sodium and potassium in tissues of the hip joint and to look for any correlations between these minerals. The study was performed using hip joint samples taken from people living in the Upper Silesian Industrial Region in Poland. Ninety one subjects, 66 women and 25 men, were included in this study. The samples were obtained intra-operatively during hip joint replacement procedures. The concentrations of magnesium, calcium, sodium and potassium were measured by atomic absorption spectrophotometry (AAS). Our results showed that these minerals are most abundant in the cancellous bone of the hip joint. They were found next more abundantly in the cortical bone and the cancellous bone from the intertrochanteric area. Levels of magnesium, potassium and calcium were lower in articular cartilage compared with other parts of the hip joint; however, sodium levels were at their highest in this tissue. The lowest levels of these minerals were found in the articular capsule. Those patients with fractures of the femoral neck had lower levels of magnesium, potassium, and calcium, but higher levels of sodium compared with the group with degenerative changes. We can also confirm that in the population studied, calcium levels in cancellous bone of the head of the femur decreased with age.
本研究旨在确定髋关节组织中镁、钙、钠和钾的分布，并寻找这些矿物质之间的任何相关性。该研究使用取自波兰上西里西亚工业区的髋关节样本进行。本研究共纳入 91 名受试者，其中 66 名女性，25 名男性。这些样本是在髋关节置换手术过程中获得的。镁、钙、钠和钾的浓度通过原子吸收分光光度法（AAS）进行测量。我们的研究结果表明，这些矿物质在髋关节的松质骨中含量最丰富。其次是皮质骨和转子间的松质骨。与髋关节的其他部位相比，关节软骨中镁、钾和钙的含量较低；然而，钠在该组织中的含量最高。这些矿物质含量最低的是关节囊。与退行性改变组相比，股骨颈骨折患者的镁、钾和钙水平较低，而钠水平较高。我们还可以证实，在所研究的人群中，股骨头部的松质骨中的钙水平随年龄增长而降低。
