Background: The role of cervical spine magnetic resonance imaging (MRI) in the evaluation of clinically unevaluable blunt trauma patients has been called into question by several recent studies.
Methods: A PubMed search was performed for all studies comparing computed tomography and MRI in the assessment of the cervical spine in patients who cannot be evaluated clinically. The radiologic findings and clinical outcomes from each study were collated for analysis.
Results: Data for 1,714 patients were available. All patients had a negative computed tomography scan and then underwent an MRI. There were 271 (15.8%) patients who had a previously undocumented finding on MRI with the majority (98.2%) being a ligamentous injury. Only 5 injuries (1.8%) resulted in surgical intervention.
Conclusions: MRI identifies additional injuries; however, the vast majority are of minor clinical significance. Routine MRI after a negative computed tomography of the cervical spine is not supported by the current literature.

Objective: To investigate the effects of modified twin-block appliances (MTBA) on obstructive sleep apnea (OSA) and mandibular retrognathia and the changes in the upper airway, hyoid bone position, and hypoxia-related inflammatory marker levels in children with OSA.
Methods: This study included children with OSA and mandibular retrognathia and those with class I without mandibular retrognathia (n = 35 each). The experimental group comprised children with OSA and mandibular retrognathia managed using MTBA.

In Japan, cervical artificial disc replacement was approved by the Pharmaceuticals and Medical Devices Agency in December 2017, and two products, Mobi-C by Zimmer Biomet and Prestige LP by Medtronic, are on the market. Cervical artificial disc replacement preserves cervical motion; however, the device must be place carefully on the midline to take full advantage of its features. In addition, a reliable foraminotomy is required to cure or prevent radiculopathy due to residual foraminal stenosis.

Anterior cervical fixation is an excellent surgical technique for the removal of anterior compressive elements affecting the spinal cord and nerve roots while addressing cervical instability. However, it is important to recognize the unique challenges posed by the proximity of critical structures, including the trachea, esophagus, carotid sheath, and recurrent laryngeal nerve. Access to the upper cervical spine is often limited to the mandible.
