In the cervical spine, deep paraspinal muscles (DPMs) function to preserve spinal stability and mobility. However, the relationship between DPMs and bone union after cervical fusion surgery has not yet been investigated. The objective of this study is to evaluate the relationship between the cross-sectional area (CSA) of DPMs and bone union after cage alone anterior cervical decompression and fusion (ACDF). ⋯ The extensor CSAs were related to fusion rate and timing. In particular, as the extensor CSAs increased, fusion timing decreased.

The utility of virtual and augmented reality based on functional neuronavigation and intraoperative magnetic resonance imaging (MRI) for glioma surgery has not been previously investigated. ⋯ Combining virtual and augmented reality based on functional neuronavigation and intraoperative MRI can facilitate resection of gliomas involving eloquent areas.

To elucidate the clinical features, risk factors for contralateral progression, and long-term outcomes of patients with unilateral moyamoya disease (MMD). ⋯ A one-peak pattern in age distribution, lower grade of Suzuki stage, fewer familial cases, and posterior cerebral artery involvement were observed in patients with unilateral MMD. Contralateral abnormalities on initial angiography and infarction at onset were risk factors for contralateral progression in adult and pediatric patients, respectively. Good functional outcomes can be anticipated in the vast majority of surgically treated patients.

Few data are available concerning clinical outcomes in patients with Parkinson disease who undergo elective thoracolumbar spine fusion surgery. The goal of this study is to elucidate complication and revision rates after posterior thoracolumbar fusion surgery in patients with Parkinson disease, with a focus on how Parkinson disease modifies these rates. ⋯ Patients with Parkinson disease are more likely to require revision surgery and have higher rates of adverse medical events postoperatively. Patients with Parkinson disease should be appropriately selected to ensure favorable clinical outcomes.

To identify the prognostic factors associated with patient satisfaction after double-door laminoplasty for cervical compression myelopathy due to ossification of the posterior longitudinal ligament (OPLL). ⋯ Patient satisfaction after laminoplasty was insufficient in patients with a hill-shaped ossification. The patients with OPLL who were able to recognize a difference in their clinical physical function, especially lower extremity function, were satisfied after laminoplasty.
