The Study: Influence of T1 Slope on the Cervical Sagittal Balance in Degenerative Cervical Spine: An Analysis Using Kinematic MRI

 

The Facts:

  1. "Kinetic magnetic resonance imaging (kMRI) is a novel noninvasive technology, which allows for patient scans in various weight bearing positions..."
  2. The authors used kMRI to look at "83 patients with degenerative cervical spine conditions."
  3. They looked at the following: "C2-C7 angle", "C2-C7 sagittal vertical axis" (SVA), cranial and cervical tilt, thoracic inlet angle, "T1 slope, and neck tilt".
  4. They settled on three key points:
    1. T1 slope and C2-C7 angle are related
    2. T1 slope has a significant correlation with the "Cobb angles of C2-C7 and SVA of C2-C7."
    3. "... large T1 slope required large cervical lordosis to preserve physiologic sagittal balance of the cervical spine."

Take Home:

T 1 slope may have profound impact on cervical lordosis.
