To radiologically measure the parameters of endplates and the apophyseal ring and to suggest an applicable length for a lumbar interbody cage for Chinese patients. ⋯ The choice of an appropriate length for a lumbar interbody cage should be based on the procedure and fusion level, which can match the endplates anatomically. The size of the lumbar interbody cage is affected by many factors, and a simple calculation may not be clinically relevant.

This is a case report of a 34-year-old man with hereditary multiple exostoses who presented with gradual tetraparesis. Neuroimaging evaluation revealed an important posterior spinal cord compression by a C3 bony formation. ⋯ Histopathologic examination of the intraspinal lesion confirmed the diagnosis of benign osteochondroma. The patient returned to a normal life without evidence of recurrence at 2-year follow-up.

Type 1 Chiari malformation (CM-I) is a craniospinal disorder historically defined by cerebellar tonsillar position greater than 3-5 mm below the foramen magnum (FM). This definition has come under question because quantitative measurements of cerebellar herniation do not always correspond with symptom severity. Researchers have proposed several additional radiographic diagnostic criteria based on dynamic motion of fluids and/or tissues. The present study objective was to determine if cardiac-related craniocaudal spinal cord tissue displacement is an accurate indicator of the presence of CM-I and if tissue displacement is altered with decompression. ⋯ These results support SCM measurement by PC-MRI as a possible noninvasive radiographic diagnostic for CM-I. Dynamic measurement of SCM provides unique diagnostic information about CM-I alongside static quantification of tonsillar position and other intracranial morphometrics.

Many articles have been published on pituitary adenomas. Bibliometric analyses are helpful for determining the most impactful studies within a field. ⋯ This study identified the research focuses and trends regarding pituitary adenoma and provides key references for investigators in guiding future pituitary adenoma research.

The neurosurgical literature rarely describes managing open head injuries caused by machetes, although this is a common head injury in developing countries. We present our experience managing cranial machete injuries in Nicaragua over a 5-year period. ⋯ An aggressive approach to managing open head injury caused by machete yields good outcomes, with the majority of patients experiencing minimal disability at hospital discharge and a low rate of infection.
