RESUMEN
The aim of this research was to study the anatomical aspects of abnormal foramen over the posterior arch of atlas vertebra. Posterior arch of atlas vertebrae was studied for abnormal foramen in sixty-seven adult human atlas vertebrae and findings were noted. In 2.98 percent of cases, unilateral complete abnormal foramen on the posterior arch of atlas vertebra was found. Clinicians should be aware about this variation on posterior arch of atlas, which may produce headache, vertigo, vertebrobasilar insufficiency and shoulder pains.
El objetivo fue observar los aspectos anatómicos de un foramen anormal presente sobre el arco posterior del atlas. Se estudiaron 67 vértebras atlas de humanos adultos. En el 2,98 por ciento de los casos, se encontró un foramen unilateral anormal completo sobre el arco posterior del atlas. Los clínicos deben estar conscientes de esta variación anatómicaen , la cual podría producir cefalea, vértigo, insuficiencia vertebrobasilar y dolores en los hombros.

It is essential to define the accurate location and extent of bony bridge in relation to the epiphyseal plate for operation of partial epiphyseal plate closure by bony bridge resection. Since magnetic resonance imaging(MRI) provides excellent tissue contrast and multiplaner image, it could be applied to the diagnosis and mapping of bony bridge of epiphyseal plate. A thirteen year old female with post-traumatic epiphyseal injury of ankle was diagnosed by MRI. We could assess the bony bridge accurately by direct sagittal and coronal images and excellent tissue contrast of MRI.
