The FDA recently approved Botox injections for another indication: spasms in the flexor muscles of the elbow, wrist and fingers.

Spasticity of the elbow, wrist and fingers can result from trauma or diseases, including trauma affecting the brain and multiple scelrosis. Patients receiving Botox for this problem experience less pain and stiffness in the treated muscle(s), allowing them to carry on with daily activities more easily. Botox is believed to be effective since it targets the spastic muscles, blocking communication between the nerves and muscles. This induces paralysis, allowing the muscles to relax.

Approval was passed in mid March. The FDA limited treatment to adults only.

Botox is also approved for spasms of the neck that result from cervical dystonia.
