Abstract
Cervical traction therapy is commonly used for cervical spondylosis; however, complications, such as subdural hematomas can occur. Possible mechanisms include cerebrospinal fluid (CSF) leakage and bridging vein damage. A 51-year-old Japanese woman developed a persistent headache after 2 weeks of cervical traction therapy. Magnetic resonance imaging revealed bilateral subdural hematomas. Bed rest, oral analgesics, and daily infusion therapy failed to improve symptoms, but 2 epidural blood patches led to recovery. Although no direct CSF leakage was found, a spinal epidural lesion may have contributed. Cervical traction therapy may cause subdural hematomas via intracranial hypotension. Clinicians should consider this risk and conduct thorough diagnostic evaluations in affected patients.
