What to buy with Comfort Cool Thumb Splint
What are the Indications of a Thumb Splint?
- The pain can develop suddenly in the thumb, wrist, or arm and may even travel up the forearm, depending on the cause of the pain
- They are designed to help with the healing of swollen, weak, and damaged joints and thumbs, along with other conditions as well
- Other treatment includes medication, steroid injections, physical therapy, and, in some cases, surgery might be required
- However, in most cases, these can be costly and may come with side-effects
- Thumb splints, braces, and stabilizers are more cost-effective, and there are no harmful side effects associated with this mode of treatment.
How do you measure your thumb for CMC Thumb Support?

- Use a measuring tape to calculate the wrist size. Place the end of the tape at the crease in your wrist and measure 10cm (4") up the forearm, then mark it.
- Then, at the 10cm mark, measure the circumference around the forearm, the "Forearm" measurement.
- Now, At the widest part of the palm, measure your hand circumference. It is called the "Hand Circumference" measurement.

Does the job.
Have used over the years for thumb CMC joint osteoarthritis. Until surgery, which corrects the problem, the thumb support helps stabilize and protect the thumb. Not stiff or uncomfortable. Highly recommend.

Comfort cool thumb orthosis by this company
It WAS a great thumb stabilizer for my trigger thumb on my left and right hand until it wasn't!
I am going for OT and was urged to contact the company to request a replacement due to the stretched out thumb area that stopped providing support on my left thumb orthosis AND the right hand orthosis split apart on the strap that wraps around the thumb. I had received both at my local Bone and Joint Center Urgent Care and the other at my Hand Specialist office.
I contacted your company customer service. They said if I didn't have billing invoice that specifically stated their company name they could not- would not - replace it.
When I explained there are only CODES on a medical receipt not Comfort Cool Thumb CMC Abduction Orthosis made by North Coast Medical.
This is outrageous !!
I would NEVER recommend this company which does not stand behind their expensive product nor does it provide ANY warranty , limited or otherwise.
My ONLY option given to me was to self purchase another one for each hand.
Please note they are 7 weeks old!!! And they are worn 4 times a week!
Patient BEWARE!!!
Option: Large Plus, Left

Great Hand Brace at a Great Price!
I bought this brace for a friend. She had one for her left hand that got injured that she received at her doctor’s office. She liked it so well that she wanted one for her right hand due to bad arthritis. It cost $46 to buy it from the doctor’s office & was under $30 on the Rehab Store site….. exact same brace.
