Spinal Implants, Part 1 – Surgical Specifications

Technological advances in medical equipment and implants have driven worldwide spinal implant sales to $10 billion annually.

Like orthopedic implants used for joint reconstruction and the surgical fixation of a bone fracture, spinal implants are subject to very specific and strict surface finishing requirements.

Mass finishing and shot blasting play a key role in creating the right finish for spinal implants, not only for intermediate surface treatment after forging, casting, machining, additive manufacturing, etc., but also for placing the final surface finish before implantation.

Rosler Metal Finishing has extensive experience in surface finishing spinal implants using mass finishing, shot blasting, and a combination of both methods.

In a series of posts, we’ll analyze the specific surface finishing requirements for spinal implants based on their functional and performance characteristics and describe the respective mass finishing and shot blasting equipment and methods available to fulfill these requirements.

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.
