Reverse cervical lordosis is when the neck loses it's normal inward curve and actually starts to curve outward(kyphosis). It most commonly follows a laminectomy for cervical stenosis and takes place over a series of years. Newer methods of treating stenosis have improved the risks of kyphosis.

However, it can also happen spontaneously when the ligaments tear and the spine support is lost usually after some kind of accident. I've had it happen in my lumbar spine(ligament tear from nothing more than standing up) and my cervical spine following surgery for stenosis and happened less than 3 months after surgery(a new record according to my neurosurgeon).

Does that answer any of your concerns?
