Taking the case history in patients with vertebrogenic disturbances, I was so struck by the high incidence of chronic relapsing tonsillitis that I took a random sample of 100 cases from my files and found that 56 had a history of chronic relapsing tonsillitis or tonsillectomy for that reason, while only 44 had no or only incidentally tonsillitis." A later systematic study was carried out under the care of an otolaryngologist. Movement restriction (hypomobility) at the craniocervical junction was found in the great majority between occiput and atlas (70 cases or 92%).
