El objetivo del presente estudio fue determinar las caracteristicas morfometricas de relevancia quirurgica de la vertebra atlas en las tecnicas mas utilizadas en la actualidad para la estabilizacion quirurgica de la union occipitocervical
y del complejo atlantoaxial.
These known anomalies, including basilar impression, occipitocervical
synostosis, odontoid anomalies, and Klippel-Feil syndrome, can present with neck pain, weakness, and upper extremity numbness.
Here, we report the case of a patient who had a type 1 OCF with craniocervical misalignment and C1-C2 translation that was treated with a halo vest followed by occipitocervical
The most used and recommended surgical procedures, with or without atlantoaxial subluxation, are the combination of spinal canal decompression by laminectomy and a posterior C1-C2 or occipitocervical
fixation with transarticular screws, without removal of the intracanal ROP .
Objective: To find out the clinical outcome of posterior decompression with occipitocervical
fixation and fusion in patients with Craniovertebral junction instability.
To the best of our knowledge, the present study describes the first case of hemolymphangioma in the occipitocervical
region, which appears to be a rare site of presentation of a rare neoplasm and reviews the clinical characteristics and management choices of this condition based on the existing available literature.

dislocations often results in death.
(2008) had reported that the clinical manifestations include severe neck pain mostly in the occipitocervical
area followed after a variable interval by ischemic symptoms.
Investigators stated that "This study demonstrates a patient-specific template technique that is easy to use, can simplify the surgical act, and generates highly accurate cervical pedicle screw placement." (43) This technique was used clinically in nine patients with basilar invagination who underwent posterior occipitocervical
fusion with template-guided placement of C2 laminar screws (Fig.
