Achieving Specific Finishes for Trauma Implants

In our last trauma implant blog, Rosler Metal Finishing discussed the materials used in trauma implants. From hip replacements to cranial plates, there are numerous uses for trauma implants; each with its own unique surface finishing needs and requirements.

Trauma implant manufacturers must achieve the necessary surface finish to ensure patient safety and best results. These finishing requirements can range from simple cleaning or deburring to surface smoothing and high-gloss polishing.

This blog will answer the question: What techniques are used to finish off trauma implants?

What types of finishes are used?

Trauma implants are subject to multiple finishing operations throughout the manufacturing process. After manufacturing steps including forging, blanking, machining, and thread cutting for screws, the workpieces usually undergo a surface cleaning (descaling, de-oiling), deburring, edge radiusing, or surface grinding operation, before they receive their final finish.

The Importance of Material Selection in Trauma Implants

Rosler Metal Finishing understands that trauma implants and medical devices are subject to stringent quality standards. Any material defect or malfunction can have catastrophic consequences for a patient. That’s why we take our work in the trauma implant field very seriously.

Also known as osteosynthetic implants, trauma implants include pins, screws, and plates used to surgically fix a bone defect. Implant manufacturers must select the right material and attain the required surface finish to ensure patient safety and best results.

Spinal Rods & Screws

In a series of blog posts, we’ll answer the most common questions about trauma implant materials and finishes.

We begin with a basic question: What materials are used in trauma implants?

The answer, in short, is usually stainless steel or titanium.

Does the material performance affect the selection?

In order to select the best material, trauma implant manufacturers must understand the specific performance attributes of the implant they are creating. Implants are subject to very strict performance and reliability standards. Selected materials must act as bone stabilizers and healing support while meeting the following guidelines.

Any time two metal parts come into contact with each other the resulting friction causes heat build up.  These high temperatures cause wear and over time reduce efficiency and eventually create the need for replacement.  By creating a smooth and shiny finish the  process improves the life and efficiency of moving metal parts.  Increased life translates into lower operating costs as well as better performance.

Three Reasons To Shot Peen Medical Implants

People associate shot peening with automotive and aerospace components.  However, did you know it’s used in the medical implant and component industry.  Bone screws, dental implants, and hip and knee replacement components are just a few of the medical implants that are shot peened.
