Thoracic Disk Herniation Incidence

Classification

• Based on their segmental level, canal location, size,

imaging characteristics, and clinical presentation

• Symptomatic thoracic disks:

– Greater prevalence in the junctional segments than in the

rigid segments

– Often classified as cervical and/or upper lumbar disk

herniations

• Central and large disks (greater than 40% of canal

diameter)

: Greater incidence of myelopathy and worse

functional outcomes

Classification

• Calcific changes to the disk and dural interface

noted on CT can predict a greater likelihood of

cerebrospinal fluid complications with

intervention

• Classification based on clinical presentation

– follows the spectrum of asymptomatic axial pain

syndromes provoked by rotation to radicular

syndromes and/or myelopathy
