Figure 1

X-ray comparison of pre- and post-intervention in Case 1. (a) The initial X-ray displayed a loss of cervical lordosis, backward subluxation of the C4 on C5 (red circle), and an occipital enthesophyte (white arrow). The cervical gravity line (blue dotted line) fell forward of the C7 suggestive of anterior head placement. (b) The 9 months follow-up X-ray showed the correction of both the neck curve and the forward head posture. The cervical gravity line fell within the C7 vertebra. Redlund-Johnell criterion (white dotted line) was reduced by 11.11% and Ranawat index (red dotted line) was reduced by 13.72%
