Chapter 8 T-Spine

T-Spine Vertebrae T1-4 smaller (Cervical like) T5-8 typical Thoracic T9-12 larger (Lumbar like) Facets for ribs

Costovertebral Joints Full facets –Accepts head of rib Demifacets – Where rib articulates with 2 vertebrae. T2-8 (2) demifacets T9 (1) demifacet

Costotransverse joints Facets on transverse process –Articulates with rib tubercles T1-10 –11&12 lacks

T-spine characteristics Spinous process projects ____________ –Ex: on AP _____________on T5 Zygapophyseal joints – __________________. Intervertebral foramina – __________________.

C&T-spine topographic landmarks _____________– C1 1” below _____ – C1 Gonion – C3 Jugular notch – T2-3 ___________– T4-5 Xiphoid tip – T9-10

T-Spine Imaging Routine AP Lateral Swimmers 40” SID 80-85kVp Recumbent

AP T-Spine Supine Have pt _________ CR to T7 – __________jugular notch Midsagittal Collimate to ________ Suspend respiration on expiration

Lateral T-Spine Supine Can place ________in small of back for support Flex knees CR to T7 & _________ from spinous process __________ technique can help blur ribs and pulmonary markings

Swimmers ____________not seen well on lateral Place pt in lateral Arm _____________raise above head Arm farthest from IR depress CR ___________jugular notch May put slight (3-5°)caudal angle if needed.
