These calcifications may disappear with time 1. The vertebral column includes 33 vertebrae that are arranged one upon the other and joined to each other by means of the intervertebral joints and ligaments, of which includes anterior and posterior longitudinal ligaments. The management of transverse ligament calcification should then be both targeted at the underlying cause of calcification (e.g., metabolic or AAI), . We conclude that transverse ligament calcification is seen frequently in the elderly and very frequently with advanced degenerative changes at the . Immediately behind the transverse ligament and odontoid process is a canal that extends the entire length of the spine. Radiographs of the cervical spine can demonstrate a calcification in the periodontoid tip area 1. 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. The morphology of the spinal cord, such as its flatness or narrowness, on MRI before operation did not correlate with the operative results in some reports, but the .

CT is the gold standard for identifying the calcification and confirming that it corresponds to the periodontal ligaments, particularly the transverse ligament of the atlas (part of the cruciform ligament) 1,2,4. Axial bone window. The cruciate ligament of the atlas (also known as the cruciform ligament) is an important ligamentous complex that holds the posterior dens of C2 in articulation at the median atlantoaxial joint. The iliolumbar ligament is a strong band of connective tissue which courses from the transverse process of L5 (in over 96% of cases) to the posterior iliac wing and crest of the ilium.

MRI is useful to look for neural element compression, signal changes, and assess for degenerative changes in the cervical spine, all of which may alter treatment or surgical strategy. Calcific deposits within the transverse ligament were seen in 40 patients (5.7%). Performing the Tests. More recently, some authors have indicated that MRI is a more sensitive indicator of transverse ligament injury than Spence's rule. Whiplash trauma can damage the transverse ligament by use of high-resolution proton-weighted MR images such lesions can be detected and classified and the reliability of this classification still needs improvement.

The radiographic detection of calcification and ossification in the soft tissues often provides an important clue to the correct clinical diagnosis. RESULTS: In the cadaveric specimen, radiography and CT demonstrated calcifications in the transverse ligament; histologic evaluation confirmed that these calcifications were CPPD crystal deposits. The transverse tarsal joint complex includes two movable tarsal joints: the calcaneocuboid and talocalcaneonavi cular joints [].The calcaneocuboid joint is formed by the quadrilateral facets of the calcaneus and cuboid bones and its capsule, which is reinforced by ligaments [].The four ligaments connecting the calcaneus and cuboid are the medial calcaneocuboid ligament, a component of the . 1. 6,11,12 Dickman et al 11 classified isolated transverse ligament injuries into two different types based on MRI: type I is an injury of the transverse ligament without concurrent atlantal fracture, and type II .
