case_images: A young woman with hEDS, CCI, and TCS. (A) Upright cervical flexion MRI showing medullary kinking (red circle) (clivo-axial angle of 116 degrees). (B) Postoperative upright MRI showing reduced medullary kinking after fixation and fusion. (C) MRI of lumbar spine showing a slightly low-lying conus at mid L2 body (red line).

case_images: An upright cervical flexion/extension MRI confirmed a diagnosis of craniocervical instability, showing clivo-axial angle in flexion of 116 degrees (clivo-axial angle of <130 degrees indicates pathologic) and medullary kinking (Figure 1A). The surgery was successful (Figure 1B), although recovery measured over the following year was delayed due to a fall at home in the immediate postoperative period, though imaging confirmed stable hardware and early bony fusion. TCS (Figure 1C).
