Report of two cases of high cervical injury: an adequate functional result with timely surgical management.

Introduction: Odontoid fractures correspond to 9-15% of cervical spine fractures. Atlas fracture is rare (3-13%).

Case Presentation: Male with Anderson and D´Alonzo Type II Odontoid fracture with unstable fragment treated with occipitocervical fixation with occipital plate, C2-C3 transfacet screws; Female with type E Jefferson fracture + anterolateral atloaxial dislocation, treated with occipitocervical fixation, C2-C3-C4 transfacet screws.

Intracranial migration of a ventriculoperitoneal shunt: A case report and literature review.

Background: The intracranial migration of a ventriculoperitoneal shunt (VPS) has been previously described, it is a very rare event, and the mechanisms of this migration have not yet been elucidated.

Case Description: Newborn at 38 weeks of gestation by cesarean section, with congenital hydrocephalus due to Dandy-Walker malformation that required right Frazier VPS placement. At 2-month follow-up, computed tomography of the skull showed cranial migration of VPS and dysfunction.

Reconstruction of depressed skull fracture in school patients. Technique description.

Objective: Depressed skull fractures are the result of trauma injuries. They are present in approximately 3% of patients who arrive to an emergency room with skull trauma. The main objective of surgical repair in depressed fractures is correction of cosmetic deformity and the prevention of infections.

Cranioplasty with cryopreserved autologous bone in craniectomized patients due to brain trauma, a current and safe option: Experience of 97 cases.

Background: Cranioplasty is the used method in neurosurgery for repairing cranial bone defects. In our environment, the most widely used material is cryopreserved autologous bone (ABCp).

Objective: A retrospective observational study was proposed in order to analyze complications in patients who underwent decompressive craniectomy for brain trauma, with subsequent cranioplasty with ABCp.

Pituitary macroadenoma apoplexy in a severe acute respiratory syndrome-coronavirus-2-positive testing: Causal or casual?

Background: In December 2019, in Wuhan, a new virus emerged, causing severe acute respiratory syndrome (SARS) secondary to infection by a type of coronavirus, causing coronavirus disease (COVID-19). The pandemic caused by the new coronavirus has had implications in the central nervous system. COVID-19 is known to be characterized by coagulation activation and endothelial dysfunction, causing ischemic and hemorrhagic vascular syndromes.

Technical note: In Mexico, the majority of 147 traumatic spinal cord injuries occurred in the thoracic spine for young males.

Background: Traumatic spinal cord injury (TSCI) is a devastating problem typically associated with multi-organ disorders. Studies regarding TSCI and their attendant comorbidities are scarce from developing countries.

Methods: The electronic files of 147 patients with TSCI (2017-2018) were reviewed; 78% of patients were males averaging 38 years of age.
