The occurrence of nickel and other elements in tissues of the hip joint

Abstract

Nickel is applied in the production of surgical instruments and compounds of nickel affect the osseous tissue. The objective of this study was to determine the contents of nickel and 11 elements in tissues of a hip joint obtained from inhabitants of the Upper-Silesian Industrial Area. The samples were collected intra-operatively during Total Hip Replacement procedures, in most cases the indication for the surgery was hip osteoarthritis. Concentrations of nickel and 11 trace elements were measured with a Pye Unicam SP-9 acetylene-oxygen flame atomic absorption spectrometer (AAS). Additional analyses were conducted to identify the correlations occurring between these elements. The average content of trace elements in the hip joint was as follows (mg kg −1): Cd 0.66, Cr 7.58, Cu 8.43, Mn 0.79, Pb 3.75, Ni 4.82, Fe 252.13, Zn 75.65, Mg 1306.19, K 3938.67, Na 7484.52, Ca 49485.44. The study demonstrated that the content of nickel and the other elements was diversified, depending on the element of the hip joint, gender and the type of affection the endoprosthesis-plasty was performed for.
