The clinical prognostic value of the Spinal Instability Neoplastic Score (SINS), in the context of vertebrectomy for neoplasia, has not yet been established. This retrospective study of 134 patients aims to evaluate the efficacy of the SINS to predict outcomes and survival after vertebrectomy for malignancy. ⋯ This study demonstrates a statistically significant increased survival in the indeterminate cohort. These results demonstrate the potential ability of the SINS to act as a clinical prognostic tool with regard to survival time.

The present study assessed early mortality (within 1 and 3 months) in patients with primary central nervous system lymphoma (PCNSL) and identified the risk factors associated with early mortality. ⋯ The rate of early mortality has declined significantly during the past 20 years. The risk factors for early mortality within 1 or 3 months after a PCNSL diagnosis included advanced age, male gender, black race, frontal lobe location, unmarried, diffuse large B-cell lymphoma, no surgery, no chemotherapy, and no radiotherapy.

The predictive ability of Elixhauser Comorbidity Index (ECI) and Charlson Comorbidity Index (CCI) have been compared in orthopedic and gastrointestinal surgery; however, their predictive ability for complications secondary to spine surgery and posterior cervical decompression and fusion (PCDF) specifically is understudied. This study examines the predictive ability of the ECI and CCI for complications and morbidity following PCDF. ⋯ ECI showed superior predictive ability to the CCI in predicting 8 of the 18 complications that were analyzed and inferior in none.

Albeit rarely, different spinal pathologies may require surgical treatment during pregnancy. The management of such cases poses a series of challenges, starting with adequate body positioning. ⋯ Gestational age, surgical comfort and maternofetal safety should be balanced by a multidisciplinary team to tailor an adequate positioning plan for each individual case. The early third trimester is the more limiting period because of the womb hindrance favoring lateral or three-quarters positionings.

Foramen magnum decompression (FMD) remains the first-line treatment for Chiari malformation type I associated with syringomyelia, although consistent approaches are not used. However, there are few reports on a persistent or recurrent syrinx or worsening neurologic symptoms after FMD. ⋯ Adults with persistent syringomyelia after FMD and the higher level of the upper segment of the syringomyelia often have a surgically remediable structural cause. The beneficial effect of a secondary decompression should be considered and guide the decision-making of patients with Chiari malformation type I-related syringomyelia.
