There are two types of Thumb Spica Splints that can be purchased for treatment of thumb arthritis. The Thumb Abduction Splint is the simplest brace to use for this purpose, but in patients with more severe symptoms, a more significant Thumb Brace may be needed. In these patients, a Thumb Spica Brace is appropriate. The Thumb Spica Brace is more supportive to the thumb, but can be awkward to use in your daily activities.
