The authors found in 53.5% of the cases of Binder's Syndrome, where a radiological work up had been carried out on the cervical spine and the spino-cervical joint, malformations of varying importance in these related structures. This lesional association had not as yet been pointed out. After pathological groupings and an analytical study of the anomalies encountered, the question of a common inducer factor is raised, or at least a factor contemporary to the two dysplasias, maxillo-nasal and vertebral. In practical terms, it would seem vital that all individuals with Binder's syndrome have a radiological examination of the cervical spine and the spino-cervical joint. In those subjects presenting with malformations and in particular, complex corporeal dysplasias, the authors strongly insist on the necessity of regular follow up in order to make an early diagnosis of eventual neurological repercussion.
