Review Meta Analysis
Evaluation on effectiveness of treatment strategies for degenerative lumbar spinal stenosis: a systematic review and network meta-analysis of clinical studies.
Lumbar spinal stenosis (LSS) is a common disease in spinal surgery. Many related treatment methods have been reported, but their effectiveness still lacks a systematic comparison. We aimed to evaluate the clinical outcomes related to the efficacy and safety of these treatment strategies via a network meta-analysis. ⋯ BDUL could effectively alleviate VAS pain of patients, and had a lower incidence of complications. Although BDUL was slightly inferior to posterolateral fusion in terms of Oswestry Disability Index improvement, the postoperative quality of life of patients treated with BDUL had been significantly improved compared with that before surgery.

The management of spine tumors is multimodal and personalized to each individual patient. Patients often require radiation therapy after surgical fixation. Although titanium implants are used most commonly, they produce significant artifact, leading to decreased confidence in target-volume coverage and normal tissue sparing. ⋯ The radiolucency of CFR-polyether ether ketone implants has the potential to benefit patients with spine tumor. Clinical studies have shown no increase in complications with implementation of CFR-polyether ether ketone implants, and these devices seem to have sufficient stiffness and pullout strength. However, further trials are necessary to determine if there is a clinically significant impact on local tumor control.

Meta Analysis
Effectiveness of pre-operative embolization in patients with spinal metastases: a systematic review and meta-analysis.
Debate on the effectiveness of preoperative embolization for spinal metastatic lesions, especially for nonhypervascular tumors, has persisted. The present study aimed to identify the effectiveness of preoperative embolization in patients who had undergone surgery for spinal metastasis. ⋯ The current data support the use of preoperative embolization for hypervascular metastatic tumors to the spine. However, little evidence is available to support the use of preoperative embolization for nonhypervascular metastatic tumors to the spine.

To compare clinical efficacy and safety of endoscopic lumbar interbody fusion (Endo-LIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in treatment of lumbar degenerative diseases. ⋯ Based on the evidence provided by this study, there is no significant difference in clinical efficacy and safety between Endo-LIF and MIS-TLIF in the treatment of lumbar degenerative diseases. Although Endo-LIF has a longer operative time, it has the advantages of less tissue trauma and rapid recovery after operation.

Virtual reality (VR) use in health care has increased over the past few decades, with its utility expanding from a teaching tool to a highly reliable neuro-technology adjunct in multiple fields including neurosurgery. Generally, brain tumor surgery with the patient awake has only been performed for mapping of language and motor areas. With the rise of VR and advancing surgical techniques, neurosurgical teams are developing an increased understanding of patients' anatomo-functional connectivity. Consequently, more specific cognitive tasks are being required for the mapping and preservation of deeper layers of cognition. ⋯ The authors advocate for the use of a VR protocol as a feasible functional tool in awake-patient brain tumor surgery by using it as a complement during cognitive screening in addition to language testing.
