Thumb arthritis can cause significant pain and limit your hand function. If you're considering injections as a treatment option, you likely have many questions. This FAQ addresses common queries to help you make informed decisions.
What are the main injection options for thumb arthritis?
Several types of injections are used to treat thumb arthritis, each with its own benefits. These options include Corticosteroid injections, Hyaluronic Acid (HA) injections and Platelet-Rich Plasma (PRP) injections
How do I know if I'm a good candidate for thumb arthritis injections?
If you're experiencing persistent pain, stiffness, or reduced range of motion in your thumb that interferes with your daily activities, and your xray confirms arthritis, you might be a candidate. It's essential to consult with a doctor who can properly evaluate your condition through a physical exam and X-rays to determine if injections are the right approach.
How is the injection procedure performed for thumb arthritis?
For optimal accuracy and to minimise discomfort, injections for thumb arthritis are often performed using ultrasound guidance. This technique allows the doctor to visualize the joint structures in real-time and precisely guide the needle to the target area. This ensures the medication is delivered exactly where it needs to be, maximising its effectiveness and reducing the risk of complications. The skin around the injection site is cleaned, and a sterile gel is applied for the ultrasound. The doctor then uses the ultrasound probe to visualise the joint and guide the needle. You may feel a brief stinging sensation during the injection.
What are the potential risks and side effects of thumb arthritis injections?
Like any medical procedure, there are some potential risks. Common side effects include temporary pain, swelling, or redness at the injection site. More serious complications, such as infection, nerve damage, or tendon weakening (especially with repeated corticosteroid injections), are rare but possible. Your doctor will discuss these risks with you before proceeding.
What are corticosteroid injections for thumb arthritis?
These injections deliver a potent anti-inflammatory medication (a corticosteroid, similar to cortisone) directly into the affected thumb joint. This helps to quickly reduce inflammation and alleviate pain.
How quickly do corticosteroid injections work for thumb arthritis?
One of the main advantages of corticosteroid injections is that they often provide rapid pain relief via their anti-inflammatory effect, usually starting within a few days.
How long can I expect pain relief to last from a corticosteroid injection?
The duration of pain relief can vary from person to person, but it typically lasts from several weeks to about 3 months.
How many corticosteroid injections can I safely have in my thumb?
Repeated corticosteroid injections can potentially damage cartilage, so doctors generally recommend limiting the number of injections per year. Your doctor will advise you on a safe treatment plan and alternative treatments including other types of injections.
What are HA injections for thumb arthritis?
Hyaluronic acid is a naturally occurring substance found in healthy joint fluid. HA injections supplement this fluid within the thumb joint, aiming to improve lubrication and reduce friction between the joint surfaces.
How do HA injections work to relieve thumb arthritis pain?
HA acts as a lubricant and shock absorber within the joint. By improving lubrication, it can reduce pain and improve joint movement.
How long does it typically take for HA injections to start working in the thumb?
Unlike corticosteroids, it may take a week or two to experience noticeable improvement with HA injections.
How long does the pain relief from HA injections in the thumb usually last?
The pain relief from HA injections can last from 6 to 18 months depending on which HA injection is used, this is much longer than corticosteroid injections.
What are PRP injections for thumb arthritis?
Platelet-Rich-Plasma (PRP) injections are extracted from your own blood. A small sample is taken and processed to concentrate platelets, which contain growth factors that can promote healing and tissue repair. This concentrated platelet-rich plasma is then injected into the thumb joint.
How do PRP injections work to treat thumb arthritis?
The growth factors in PRP stimulate the body's natural healing processes, potentially aiding in the repair of damaged cartilage and reducing inflammation in patients with mild thumb osteoarthritis.
How long does it take to see results from PRP injections in the thumb?
It often takes several weeks or even months to experience the full benefits of PRP injections.
How many PRP treatments are usually recommended for thumb arthritis?
A series of injections may be recommended for optimal results, depending on your individual response to treatment. One injection for the thumb is usually enough. However, up to three injections can be expected.
Corticosteroid vs. HA injections: Which is the better choice for thumb arthritis?
Corticosteroids provide faster, but often shorter-term, pain relief. HA offers potentially longer-lasting lubrication and may be more beneficial for some in the long run. The best choice depends on your individual needs and your doctor's recommendation. Click here for a detailed comparison we published in relation to knee osteoarthritis.
PRP vs. Corticosteroid injections: Which is more effective for thumb arthritis?
Corticosteroids typically provide quicker pain relief, while PRP may offer more long-term benefits by potentially promoting healing. More research is still being conducted to directly compare their effectiveness for thumb arthritis.
Can thumb arthritis injections cure my arthritis?
No, injections are not a cure for arthritis. They are designed to manage symptoms such as pain and inflammation. While they can provide significant relief and improve function, they don't address the underlying cause of the arthritis.
How do I choose the right type of injection for my thumb arthritis?
The most suitable injection depends on various factors, including the severity of your arthritis, your overall health, your medical history, and your treatment goals. The best approach is to consult with an experienced doctor who can assess your individual situation and recommend the most appropriate treatment plan.
