We sought to acquire the whole sagittal spine parameters and investigated the acceptable chin-brow vertical angle (CBVA) for neutral position radiography in an asymptomatic Chinese population. ⋯ An acceptable range of -1.5° to 5.8° is recommended for the CBVA for cervical radiography in the neutral position. When spinal surgeons evaluate the cervical plane, the effects of the CBVA deviation on cervical curvature must be considered.

Accidental foreign body ingestion is a common occurrence; however, extraluminal migration is uncommon. We report for the first time in the literature an unusual migration of an ingested foreign body into the spinal canal through the vertebral body and discuss its possible route of migration. ⋯ Type, size, and shape of the foreign body determine the course of foreign body migration. A possible route of foreign body migration into the spinal canal is the Hahn canal and basivertebral foramina.

Successful use of extracorporeal membrane oxygenation for respiratory failure after cranial surgery.
The use of extracorporeal membrane oxygenation (ECMO) for cardiopulmonary support is indicated for refractory respiratory failure but carries a high morbidity and mortality in the neurosurgical setting due to associated risks of intracranial hemorrhage. ⋯ Our case report is significant because it describes the safe use of ECMO in a controversial setting because our patient had recently undergone craniotomy. We conclude that in dire circumstances the use of ECMO is appropriate and may be safe even in the setting of recent craniotomy.

Metastatic brain tumors and glioblastomas are the 2 of the most common brain neoplasms in adults. However, distinguishing solitary metastatic brain tumors from glioblastomas on conventional magnetic resonance imaging remains particularly challenging. Thus, we aimed to retrospectively assess the role of contrast-enhanced fast imaging employing steady-state acquisition (CE-FIESTA) imaging in distinguishing between metastatic brain tumors and glioblastomas. ⋯ CE-FIESTA images may provide useful information for distinguishing metastatic brain tumors from glioblastomas, especially when focusing on differences in the peritumoral brain parenchyma.

We sought to develop a new posterior fusion technique composed of bilateral C1 titanium cables and C2 pedicle screw-rods for treatment of atlantoaxial instability not suitable for C1 screw placement. ⋯ Posterior atlantoaxial fixation using C1 titanium cables and C2 pedicle screw-rod construct appears to be an effective and safe technique for treatment of atlantoaxial instability, which could be an alternative method for cases unsuitable for C1 screw placement when using C1-C2 screw fixation.
