Fracture of the odontoid process is a critical injury to diagnose and often treat. The aim of this anatomic study was to present a comprehensive understanding of this part of the C2 vertebra. ⋯ Improved knowledge of the anatomy, structural composition, and variations within the C2 vertebra may allow for better treatment options and patient care.

Accurate survival estimate is necessary when determining the most appropriate treatment modality for metastatic spinal tumor. The main purpose of this study was to identify the prognostic factors of spinal metastasis and establish a decision tree model. ⋯ A new decision tree model for prognosis prediction in spinal metastasis was established with a satisfactory accuracy and consistency. However, the Tokuhashi and Tomita systems were presented to be less correlated between the scores and actual survival.

Review Meta Analysis Comparative Study
Assessing the Difference in Clinical and Radiological Outcomes between Expandable Cage and Non-Expandable Cage among Patients undergoing MIS-TLIF: A Systematic Review and Meta-Analysis.
Minimally invasive transforaminal interbody fusion (MIS-TLIF) has been shown to have excellent outcomes for surgical management of degenerative disc disease. However, the challenge is in addressing coronal imbalance and restoring lumbar lordosis and sagittal alignment. Use of expandable cages in MIS-TLIF has been hypothesized to circumvent this disadvantage. An indirect meta-analysis of the evidence is presented comparing outcomes from expandable cages with those from nonexpandable cages, in patients undergoing MIS-TLIF. ⋯ Our results indicate that there may not be a significant difference in clinical and radiologic parameters between expandable cages and nonexpandable cages among patients undergoing MIS-TLIF, and it is unclear if the higher cost of the expandable cages is justified.

Review Meta Analysis Comparative Study
Comparison of Frame-based vs Frameless Intracranial Stereotactic Biopsy: Systematic Review and Meta-Analysis.
Frame-based stereotaxy has generally been considered the reference standard for brain biopsies. However, frameless stereotaxy might expedite the efficiency of the clinical work flow. Conflicting findings have been reported regarding the relative efficacy and safety of frame-based and frameless needle biopsy of brain lesions. We performed a meta-analysis of the reported data to compare the relative efficacy, safety, and time efficiency of frame-based and frameless stereotactic needle biopsy. ⋯ The results from our meta-analysis suggest no significant differences exist between frame-based and frameless biopsy in diagnostic yield, morbidity, and mortality. Frameless biopsy is associated with shorter procedural times relative to frame-based biopsy. We have also discussed the relative merits of frame-based and frameless biopsies.

Review Meta Analysis
Meta-analysis of the prognosis of Different treatments of symptomatic moyamoya disease.
The purpose of this study was to evaluate the efficacy of surgical revascularization versus conservative treatment and different surgical modalities, in order to provide evidence for the patient with moyamoya disease (MMD) to choose the appropriate treatment. ⋯ In patients with symptomatic moyamoya disease, bypass surgery is more effective than conservative treatment to prevent future strokes. In surgical patients, direct bypass seems to reduce the risk of stroke more than an indirect bypass.
