Reflex sympathetic dystrophy (causalgia) treatment with guanethidine

Area of Science:

• Neurology
• Pain Medicine
• Orthopedics

Background:

• Cervical spondylosis is a degenerative condition affecting the neck vertebrae.
• Reflex sympathetic dystrophy (RSD), also known as causalgia, is a chronic pain condition.

Observation:

• Three patients with cervical spondylosis presented with symptoms of reflex sympathetic dystrophy.
• Two cases were associated with acute cervical trauma.
• Symptoms included bilateral arm/hand burning pain, segmental hyperalgesia, and edema.

Findings:

• Oral guanethidine sulfate demonstrated effectiveness in treating all three cases.
• The study supports the role of norepinephrine hypersensitivity in the pathophysiology of RSD.

Implications:

• This research highlights a potential link between cervical spondylosis and RSD.
• Norepinephrine hypersensitivity may be a key target for managing RSD in these patients.
• Early diagnosis and treatment with agents like guanethidine sulfate can improve outcomes.
