Everything You Need to Know About Allergy with Orthopedic Implants

To fix various orthopedic conditions like fractures and differences in the limbs, different types of orthopedic implants are used.


Some of the most commonly used trauma implants are Locking Compression Plate, Hand Fracture Implants, Antegrade Intramedullary Nail, and Elastic Intramedullary Nail.

These Orthopaedic Implants are made of metals and the most commonly used are stainless steel and titanium. Cobalt-chrome is also known to be used for the manufacturing of trauma implants.


Now, the point here to be noticed is that some people have allergies to metals and some might develop after the application.


In this post, we will discuss some important parameters about allergies that might develop with the use of orthopedic devices.


Though these conditions are rare, knowing about them is important.

Types of Allergies that could occur after using Orthopedic Implants

Hypersensitivity or allergy could be seen after using metal trauma implants. Both these terms allergy and hypersensitivity are used interchangeably but they are not exactly the same.


Hypersensitivity is the condition where the body’s immune system causes harmful effects on the body, whereas allergy is defined as the condition when the immune system reacts to other substances i.e. foreign materials.


Metals Used for Making Orthopedic Implants

In general, there are three types of metals that are commonly used for the manufacturing of orthopedic devices:


Stainless Steel

Cobalt – Chrome

Orthopedic implants are not made of single metal rather they are made of alloys. But the proportion of base metal is the highest and other metals are added in smaller quantities.


The most commonly used metals that are added to the base metal are nickel and aluminum.

Now, it is seen that people have allergies to metals like nickel and even a small amount present in orthopedic implants could be harmful to nickel-sensitive people.

Allergy and Implants

When we talk about allergic complications associated with implants; then the patient could experience pain and other problems with the implant applied.


Besides this, some reactions may also occur but their chances are highly rare.


Several studies have also found that people with trauma implant fixed also experience pain and irritation around the operated site.


This could be due to allergy or metal sensitivity but the right cause can only be detected after a thorough examination.


In certain cases, skin sensitivity may also occur and if the condition is serious, the doctor might have to remove the implant.

Nickel Sensitivity

According to some studies conducted globally, it is found that around 10 – 15% of the population is sensitive to nickel.


So, if metal-made orthopedic devices are used in such people, the chances are very high that allergic conditions might occur. Thus, titanium-made implants will be the best option for nickel-sensitive people.


But here’s a good thing, that the chances of allergies in people with known skin sensitivities are very low with metal implants.
