“…Occipitocervical synostosis is a congenital fusion of C1 with the base of the occipital bone. It may be clinically relevant, as it may compress the brainstem, vertebral artery and cranial nerves due to the narrowing of the foramen magnum [ 39 , 40 , 41 , 42 ]. This variant is also known in the literature as occipitalization of the atlas, atlantooccipital fusion or atlantooccipital assimilation [ 43 ].…”

Background: Ponticulus posticus (PP) is a medical term that describes an anomaly of the atlas (C1), which has a complete or partial bone bridge over the vertebral artery (VA) groove. The purpose of the study is to estimate the prevalence of PP in patients with a diagnosis of migraine. Methods: Cone beam CT (CBCT) scans (n = 220) were reviewed for the detection of PP in the University “G. D’Annunzio” of Chieti in the Department of Medical, Oral and Biotechnological Sciences. The sample included 220 Italian patients between 18 and 87 years. Pearson chi-square analysis (p < 0.05 and 95% CI) was used to establish an association between migraine and PP. Results: The present study found a prevalence of PP of 20.9% and a prevalence of migraine of 12.272%. The association between migraine and PP was confirmed by the chi-square statistic, since the p-value was 0.008065 (significant at p < 0.05). PP was more frequent in the migraine without aura group, without a statistical difference relative to the migraine with aura group. Conclusions. The study concluded that PP is positively associated with migraine.

“…These include complete or incomplete types, complete synostosis being the most common. 5 Synostosis may be associated with other skeletal malformations, such as spina bifida of atlas, occipital vertebra, basilar invagination, Klippel-Feil syndrome, Arnold-Chiari malformation and cervical stenosis. 6 Knowledge of atlanto-occipital synostosis is important from the clinical point of view due to the vertebral artery position and the first spinal nerve (C1).…”

Atlanto-Occipital Synostosis in a Colombian Population Sample

2018

Introduction The Cervico-capital rotation process involves important joints with respect to the neurological field. Among these joints, the atlanto-occipital joint accounts for 40% of the total rotation process and its anatomical changes may affect the joint, i.e when the synostosis of both bones occurs. This anomaly has a reported incidence in the world population of 0.14% to 0.75%. To determine whether this incidence range also corresponds to the Colombian population, atlanto-occipital fusion in Colombian patients was studied. Materials and Methods The presence of atlanto-occipital fusion was assessed in a random sample of 105 skulls of a Colombian population. Morphometric features were evaluated by using a Vernier caliper. Results Out of the total sample two cases of atlanto-occipital fusion were identified. One of them exhibited a bilateral fusion between the anterior arch of the foramen magnum and the lateral masses of the atlas; the other one exhibited a left hemisynostosis that compromises the anterior arch foramen magnum and left lateral mass of atlas. The overall frequency of occurrence was 1.9%. Conclusion A greater incidence of atlanto-occipital fusion was found in contrast to the range of world incidence reported in the literature.
