There are a number of different wrist support options on the market, offering either compression, stability or both. For thumb specific injuries there are also thumb support (spica) options which immobilise just the thumb so that your wrist and fingers are not impaired.
Diagnosis is essential in being able to determine the right product for you, however the severity of an injury can also determine this and what your needs are i.e. a mild sprain may simply require a compressive wrist support whereas a bad sprain may require a more rigid design to offer stability.
