Bone screws in orthopedics are used for attachment of implants to the bone, bone to bone fixation, or for soft tissue fixation or anchorage. Mostly made of Titanium, these screws are specially designed with threads that maximize initial contact, enhance the surface area, dissipate and distribute the mechanical load. Depending on the application and function, the bone screws have different designs.

A basic bone screw has four parts: Core, Threads, Head, and Tip. The manufacturer of bone screws needs to closely inspect and measure them to ensure that each parameter of the screw is as per the specified design. The Sipcon Part Quickie can be used for these bone screw measurements. This image-based measurement system enables small parts inspection and measurement and can instantly measure over 100+ dimensions in one second. The system has the following features.

1. Automatically compare bone screws against their CAD data.
2. Measurements are done regardless of the orientation of the bone screws.
3. The extended depth-of-field enables the entire screw to remain in focus even at the helix angle eliminating the need to constantly re-focus.
4. Measure bone-screws thread major and minor diameters.
5. The helix angle can be accurately measured using the rotary stage.
