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.

I am happy with the brace so far. It comes with a sleeve and the brace is easy to put on and provides ample coverage & protection.

It kind of works

The problem I find with it is that it doesn’t go over the meaty part of the thumb on the palm. The plastic curl isn’t far enough so it’s uncomfortable. It does immobilize the movement between the thumb and palm, just enough to help though. It isn’t the fit, just my kind of arthritis I think.

This product is great. Obviously manufactured with a high degree of quality and craftsmanship. Unfortunately, it will not work for my specific needs without some minor modifications for proper fit.

Great for Thumb Immobilization

I've been wearing this splint at night to allow my thumb to rest fully (I wear a less restrictive and more functional splint during the day), and it has made a real difference. Also, it's very comfortable when worn with the lining. I definitely recommend it.
