Review Case Reports
Acquired Chiari I Malformation with Syringomyelia secondary to Colloid cyst with Hydrocephalus - Case report and review of literature.
Acquired Chiari malformation and associated syringomyelia have been previously described following lumbar puncture/drainage, lumboperitoneal shunts, and spontaneous cerebrospinal fluid leakage. In addition to these etiologies, space-occupying lesions such as meningiomas, epidermoid cysts, medulloblastomas, and arachnoid cysts are rare causes of acquired Chiari malformation and syringomyelia. We report a rare case of colloid cyst with hydrocephalus causing secondary Chiari malformation with syringomyelia. ⋯ Colloid cyst with hydrocephalus is a rare cause of secondary Chiari malformation with syringomyelia. Surgical management of the underlying lesion improves acquired Chiari malformation and associated syringomyelia.

Case Reports Multicenter Study
Initial Clinical Experience with AView-A Clinical Computational Platform for Intracranial Aneurysm Morphology, Hemodynamics, and Treatment Management.
The management of intracranial aneurysm (IA) is challenging. Clinicians often rely on varied and intuitively disparate ways of evaluating rupture risk that may only partially take into account complex hemodynamic and morphologic factors. We developed a prototype of a clinically oriented, streamlined, computational platform, AView, for rapid assessment of hemodynamics and morphometrics in clinical settings. To show the potential clinical utility of AView, we report our initial multicenter experience highlighting the possible advantages of morphologic and hemodynamic analysis of IAs. ⋯ AView has the potential to confirm decisions to treat IAs, suggest which among multiple aneurysms to treat, and guide treatment decisions. Furthermore, the flow visualization it affords can inform aneurysm treatment planning and potentially avoid poor outcomes.

Comparative Study
Comparation of two operative methods for treating laterocollis and torticollis subtypes of spasmodic torticollis. Follow up of 121 cases.
The aim of this study was to compare the effects and complications of microvascular decompression (MVD) and neurectomy of spinal accessory nerve in the treatment of laterocollis and torticollis subtypes spasmodic torticollis (ST). ⋯ MVD for ST of laterocollis and torticollis subtypes can provide satisfactory and lasting improvements without nerve impairment. MVD is to be preferred to neurectomy of accessory nerve in treating ST of laterocollis and torticollis subtypes.

Comparative Study
A Retrospective Study of Thoracolumbar Fractures Treated with Fixation and Non-fusion Surgery of Intra-vertebral Bone Graft Assisted with Balloon Kyphoplasty.
Posterior fixation and fusion is the primary treatment for thoracolumbar fractures, although this treatment may sacrifice range of motion (ROM) to achieve stability, rather than treating the fracture itself. Two issues addressed when treating thoracolumbar fractures are 1) replacing the fractured vertebrae, especially the upper end plate of the injured vertebrae and 2) providing strong fixation with biomechanical stability and flexibility. ⋯ Nonfusion treatment of intravertebral bone graft assisted with balloon kyphoplasty showed good fracture reduction, deformity correction, fracture healing, and ROM maintenance. There were no complications associated with the implant.

Occasionally, a favorable clinical disease-specific outcome does not reflect into improved generic health-related quality of life (HRQoL) in patients with idiopathic normal-pressure hydrocephalus (iNPH) at 1 year after the installation of a cerebrospinal fluid shunt. Our aim was to identify factors causing this discrepancy. ⋯ Frail patients suffering from certain pre-existing comorbidities may not experience improvement in generic HRQoL despite of a favorable clinical disease-specific response. Acknowledging the comorbidity burden of the patient may help clinicians and the patients to understand the conflict between patient-reported and clinical outcomes.
