Subluxation of the vertebral joint is a serious health condition that poses the risk of paralysis in vertebrates. Making the diagnosis of "subluxation" in animals and humans requires direct evidence that XXX, usually by plane x-ray, CT scan, or MRI imaging.

"wry neck"
Subluxation of the first of the cervical vertebrae (C1-C2) can cause this condition. When displacement of the joint is one-sided (unilateral) , there is typically a "cock-robin" deformity. Correction may require surgery, but has been reported, in some cases of acute trauma to older children, to be brought about by a combination of traction and prolonged television watching!. Neurosurgeons have warned that the diagnosis may be difficult to make on imaging: the angle of the jaw can overlay and obscure the area on plain film, MRI must sometimes be done at more than one angle of cut, and - once non-Titanium metal is in place for traction screws, this imaging modality (currently considered optimal) may not be able to be used at all for fear of movement of the hardware by the magnet.(B.

In young children, halo fixation has been used to correct the condition. (Caird, Michelle S. MD*; Hensinger, Robert N. MD*; Weiss, Nicole CO†; Farley, Frances A. MD*.
