Chamberlain line

Chamberlain line is a line joining the back of hard palate with the opisthion on a lateral view of the craniocervical junction.


It helps to recognise basilar invagination which is said to be present if the tip of the dens is >3 mm above this line.

McGregor developed a modification of the Chamberlain line for when the opisthion could not be identified on plain radiographs.
