Why Do I Need a Brace to Help with Thumb Arthritis and Other Injuries?

Your thumb joint has a rather large range of motion, making it one of the most mobile joints in your entire body. Unfortunately, this extra mobility can cause increased stress on your thumb joint. When you stop to think about how often you use your thumbs, it's easy to understand why you might be experiencing pain.

labeled thumb joint anatomy affected in thumb pain

BraceAbility’s rigid, thumb splint is one of the most popular thumb support braces on the market for good reason. It was designed to protect your thumb, provide pain relief, and offer comfortable immobilization to your metacarpophalangeal (MCP) and carpometacarpal (CMC or saddle) thumb joints, leaving your IP joint free bend as usual for enhanced mobility.

This thumb joint stabilizer can help treat many causes of thumb pain and conditions including:

CMC Joint Brace for Arthritis Treatment

As mentioned, this comfortable thumb splint can help with arthritis. Thumb arthritis, often referred to as basal joint arthritis or thumb rhizarthrosis, is actually the most common form of arthritis in the hand. It typically causes swelling, stiffness, and pain at the base of your thumb, as well as a diminished range of motion and grip. Trauma or injury can increase your risk of developing thumb arthritis, or you might experience wear-and-tear osteoarthritis.

Top-Rated Features of This Hard Plastic Thumb Splint

As mentioned previously, your thumbs help you accomplish an incredible amount of the activities and tasks you perform every day. It can’t be stressed enough how important your thumbs are in your ability to go about your daily activities (even the most basic ones). Following we detail why this thumb brace stands out from similar immobilizers.

  1. Low-Profile Design for Everyday Use

    This rigid thumb splint has a low profile design, allowing you to wear this brace during most daily activities (leisure and vigorous), as it stays in place quite well. Plus it’s lightweight, so you don’t feel like you’re lugging around a cast all day.

    While still immobilizing your lower thumb joints, this brace does let your top thumb knuckle flex a little bit, and your fingers have a full range of motion too!

    The freedom of this brace allows you to perform activities, hobbies, and sports such as basketball, tennis, gaming, sleeping, gardening, writing, typing, driving and cooking.

    However, it’s important to note that everybody is different and you might not be able to wear the brace depending on what hobby you're performing or the anatomy of your hand.

    Can I wear gloves over this thumb stabilizer?

    If necessary, you can also wear this thumb stabilizer under most loose-fitting gloves, think gardening, winter, or work gloves.

  2. Durable, Waterproof Thumb Splint

    This resilient, brace for arthritis and more offers a lot of support for your thumb by keeping it in the correct position and taking pressure off of damaged areas. Made out of a hard, hypoallergenic plastic material, it can withstand a lot of wear, which is great because you will probably be wearing it a lot.

    Hypoallergenic means it’s completely latex and neoprene free (some people can react to neoprene and it’s the material used in a large number of braces).

  3. Protective Glove and Extra padding Included to Enhance Comfort

    The rigid plastic that this thumb brace is constructed out of can become somewhat uncomfortable against your skin over the course of the day. To eliminate any discomfort you might experience, a soft, universally sized, polyester undersock and an extra padded piece are included with your purchase. The glove and extra adhesive pad help prevent the thumb brace from rubbing or chafing against your skin.

    Although the brace comes with one thumb / hand sleeve, some people prefer to have at least two on hand for alternating while washing, or wearing two at a time for extra support, warmth, or protection. If needed, extra protective gloves are available for purchase here.

  4. Medical-Grade Fastener Strap

    Featuring just one high quality, fastener strap, this guard for your thumb joint is a breeze to apply and easy to adjust. The strap is constructed out of medical-grade fastener, making it 10 times stronger than most retail-grade braces on the market. Retail-grade fasteners are only made to open and close 90 times, as opposed to our medical-grade fasteners, which is made to open and close at least 900 times.

  5. Perforated Holes for Breathability

    The perforated holes in this thumb spica splint offer additional comfort and breathability, especially, so your hand can breathe and will not get sweaty. The hand support for arthritis also has a special raised edge at the thumb and forefinger area to avoid unwanted pressure.

73 years old woman with arthritic tendinitis in left thumb

I am extremely happy with my brace that has allowed me to sleep at night comfortably with much less pain. I am wearing it to garden and drive my car. Just received a cortisone shot and plan to use my brace to garden, etc. to avoid future flair ups.

Great brace!

It has been very helpful. The left brace (size small) is actually a bit loose, but the right one is perfect, also size small. Is there any way in which I could tighten the left brace? I still use it swimming .

Supports thumb joint well

It supports my thumb joint better than the softer ones that I bend thumb on. My main complaint is the Velcro strap is too wide for slot so not easy to adjust the fit. Better after I trimmed the sides of the strap.

Thumb brace

At 1st I found it a bit hard, but with time this has helped my pain considerably. I usually only wear it when I'm at work since I use my hands so much and I will be pain free for a day or two after using it. Thank you for the relief!
