The osteogenesis of the vertebrae was accomplished with both perichondral a...
متن کاملPossible role of extracellular nucleotides in ectopic ossification of human spinal ligaments.
To reveal the involvement of extracellular nucleotides in the ossification process in ossification of the posterior longitudinal ligament of the spine (OPLL), the mRNA expression profiles of P2 purinoceptors, mechanical stress-induced ATP release, and ATP-stimulated expression of osteogenic genes were analyzed in ligament cells derived from the spinal ligament of OPLL patients (OPLL cells) and ...
متن کاملRadiographic study of ossification of the pterygospinous and pterygoalar ligaments by the Hirtz axial technique.
The correct radiographic identification of ossification of the pterygospinous and pterygoalar ligaments plays an important role in surgical procedures for the treatment of trigeminal neuralgia. Most of these procedures are performed through the foramen ovale, a site where these ligaments can be found to be partially or completely ossified. We studied the radiographic features of these ossified ...
