Head-supporting sign during reclining: an indication of craniovertebral junction involvement.
The craniovertebral (CV) junction can be involved in many diseases, e.g. rheumatoid arthritis, as well as destructive bone pathologies such as tumour and tuberculosis (craniovertebral Pott's disease). While some of these patients present acutely with neck pain and neurological deficits, in others the signs and symptoms may be more subtle. Two patients with CV junction involvement are described. One patient suffered from fracture of the anterior arch of atlas after being involved in a motor vehicle accident and the other had craniovertebral Pott's disease. A detailed history and clinical examination was carried out paying special attention to the situation when patients attempted to recline or while getting up from a reclining position. Patients were further investigated with imaging studies which focused on the CV junction. It was noted that patients with CV junction involvement frequently support their head while attempting to recline or when getting up from a reclining posture. This head supporting sign may be the sole neurological finding in some patients with involvement of the CV junction.
