|December 24, 2003
Summary
Spectrography analysis of hip arthroplasty wear revealed that microelements (MEs) like cobalt, chromium, and molybdenum are discharged primarily in the first year. Concentrations then stabilize, indicating minimal wear of the friction pair.
Area of Science:
- Materials Science
- Biomedical Engineering
- Analytical Chemistry
Context:
- Hip arthroplasty is a common procedure to address hip joint issues.
- Wear debris from implants can impact patient health.
- Accurate monitoring of implant wear is crucial for long-term success.
Purpose:
- To analyze the release of microelements (MEs) from a specific hip arthroplasty.
- To assess the wear rate of the comochrome friction Protasu-21WF implant.
- To determine if ME levels in patient tissues and fluids indicate excessive implant wear.
Summary:
- Tissue, hair, and urine samples were analyzed using spectrography.
- The study focused on microelements (cobalt, chromium, molybdenum) from the hip endoprosthesis.
- Higher ME discharge was observed in the first year of use, followed by stabilization.
Impact:
- The findings suggest minimal wear of the Protasu-21WF friction pair.
- Spectrography provides a valuable tool for monitoring implant performance.
- This research contributes to understanding long-term implant safety and efficacy.

01:18Effects of EDTA on End-Point Detection Methods
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...

01:15High-Performance Liquid Chromatography: Types of Detectors
The role of the detectors in High-Performance Liquid Chromatography (HPLC) is to analyze the solutes as they exit from the chromatographic column. The detector recognizes the solute's property and generates corresponding electrical signals, which are converted into a readable graph of the detector's response versus elution time called a chromatogram at the computer. There are several types of HPLC detectors, each with its own advantages and limitations, depending on the analyte properties and...
01:27Atomic Absorption Spectroscopy: Overview
Atomic absorption spectroscopy (AAS) is a technique used to analyze elements by measuring electromagnetic radiation (EMR) absorbed by atoms, which causes them to transition to a higher-energy orbit. The most crucial step in AAS is atomization, where the analyte is converted into gas-phase atoms, typically through a flame or furnace. Some of these atoms become thermally excited in the flame, while most remain in the ground state.

For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.

01:20Atomic Emission Spectroscopy: Overview
Atomic emission spectroscopy (AES) is an analytical technique used to determine the elemental composition of a sample by analyzing the light emitted from excited atoms. In AES, atoms in a sample are excited to higher energy levels by thermal energy from high-temperature sources, such as plasma, arcs, or sparks. When these excited atoms return to lower energy states, they emit light at specific wavelengths characteristic of each element. The resulting atomic emission spectrum, which consists of...

AES is a powerful analytical technique, especially effective when used with plasma sources, producing abundant spectra in characteristic emission lines. The Inductively Coupled Plasma (ICP), in particular, yields superior quantitative analytical data due to its high stability, low noise, low background, and minimal interferences under optimal experimental conditions. However, newer air-operated microwave sources are emerging as promising alternatives that could be more cost-effective than...
