Abstract
Objectives: A diagnostic imaging in a fifty five year-old woman diagnosed orthopedically as ossification of posterior longitudinal ligament (OPLL) at C5 and C6 levels was reinterpreted for Chuna mannual therapy. The cervical spinal lesion in simple X-ray and CT scan images was discussed by spinal listing systems and disc block subluxation theory. The primary adjustive target was C4 disc block subluxation, which had been affected by kyphosis. Chuna manual therapy based on diagnostic images could be helpful for adjusting spinal subluxation, correcting its adaptation curvature, and preventing its latent pathology efficiently.
