title: Association of transverse ligament calcification with anterior atlanto-odontoid osteoarthritis: CT findings.
abstract: The craniocervical junction was assessed in 700 consecutive unselected patients undergoing CT of the brain or paranasal sinuses, to investigate whether transverse ligament calcification was associated with advanced degenerative changes at the anterior atlanto-odontoid (AO) joint. Calcific deposits within the transverse ligament were seen in 40 patients (5.7%). The prevalence of this condition increased with age. Advanced degenerative changes (marked osteophytes and obliteration of the joint space) at the anterior AO joint were significantly more frequent in patients with transverse ligament calcification than in age-matched controls. We conclude that transverse ligament calcification is seen frequently in the elderly and very frequently with advanced degenerative changes at the anterior AO joint.
