Preventing Corrosion, Defects and Scratches on Orthopneic Implants

Taylor Hobson offers solutions for manufacturing process control, sample development, and analysis of scratches and defects.

Hips – Extending Implant Life

Surface Finish and Form

Orthopedic implants, such as femoral heads, sockets and stems, are manufactured with a high degree of smoothness and very low form error in order to function as low wear bearings. The surfaces are subject to both wear and damage during in vivo use. Articulating surfaces naturally wear during normal use. The calculation of the volume of the component and the volume of worn material are enabled by the 3D mapping techniques used on Taylor Hobson instruments. This is an important part of enhancing the safety and quality of implants by analyzing the wear and damage found on explanted components.

Advanced Surface and Wear Measurement

Talyrond systems by Taylor Hobson measure form and topography simultaneously, identifying areas of corrosion or wear, giving precise dimensions to calculate the volume of material loss. This is achieved with the help of a high resolution gauge (0.3 nm), a frictionless air-bearing spindle and precision axial and radial datums for measurement of straightness, roundness and cylindricity. A patented gauge calibration technique for the measurement of height, radius, distance, length, and angle is also incorporated by the system.

Taylor Hobson’s 3D analysis software, TalyMap, is capable of:

  • Accurate calculation of wear volume
  • Radius and form error analysis
  • Control of surface quality for improved durability
  • Control of taper angle and form to reduce wear
  • Thorough understanding of material loss patterns

Knees – Improving Prosthetic Piece Performance

Premature failure leads to revision surgery, and wear on joint prostheses is the main cause of such failures. Making longer-lasting prosthetic components is a challenge to the industry. Moreover, quality control has to be maintained during the manufacturing process and is key to improve the performance of prosthetic pieces. Taylor Hobson’s combined equipment like the CCI, Talyrond, and Form Talysurf have provided a better understanding of these points.

Orthopedic Articulating Surfaces – Knee Implant

The first knee replacement surgery was performed in 1968, and since then its effectiveness has been considerably increased through design, manufacture and materials. Total knee replacements have become one of the most successful medical procedures, thanks to manufacturing process control, together with the comprehensive measurement and analysis of surface texture, form and wear.

Compare Performance of Materials and Lubricants using 2D and 3D Analysis Techniques Through Wear Scar Analysis

There are non-contact and contact measurement techniques for analyzing the wear of components using both 2D and 3D analysis techniques to measure the amount of material that has been worn away.

Cylinder Mapping of 3D Components for Analysis of Volume and Material Loss

This type of measurement is especially crucial in implants, where the material lost has to be tackled by the body and where the void left behind can host infections and other foreign bodies.
