Article Synopsis
- The study aimed to investigate if preoperative opioid education can lower opioid consumption after spine surgery and to identify the most effective educational methods.
- Patients received various forms of education, including a 2-minute video, handouts, a small class, or one-on-one sessions, while the control group received standard education.
- Results showed that at 1 and 3 months post-surgery, those educated via video, class, and one-on-one sessions had reduced opioid use, with the video and class methods remaining effective even at 6 months post-op.
Article Synopsis
- - The study aimed to analyze how the density of bone foam affects the amount of subsidence caused by expandable interbody cages during spinal procedures.
- - Results indicated that higher bone foam densities led to reduced subsidence depths; for example, at a force of 150 N, the mean subsidence was 2.0 mm for 5 PCF and only 1.1 mm for both 15 and 20 PCF.
- - The findings suggest that surgeons should consider bone quality when using expandable interbody cages, as the relationship between bone density and subsidence can influence the effectiveness of the procedure.
Atypical parkinsonian syndromes, also known as Parkinson-plus syndromes, are a heterogeneous group of movement disorders, including dementia with Lewy bodies (DLB), progressive supranuclear palsy (PSP), multisystem atrophy (MSA), and corticobasal degeneration (CBD). This review highlights the characteristic structural, functional, and molecular imaging features of these complex disorders. DLB typically demonstrates parieto-occipital hypometabolism with involvement of the cuneus on FDG-PET, whereas dopaminergic imaging, such as [I]-FP-CIT SPECT (DaTscan) or fluorodopa (FDOPA)-PET, can be utilized as an adjunct for diagnosis.

Introduction: The use of drains after primary total joint arthroplasty (TJA) has shown little benefit. Few studies have investigated drain usage after revision TJA. The purpose of this study was to determine whether utilizing suction drains is beneficial for patients undergoing revision arthroplasty.

- * Recent studies indicate that surgical treatments for DCM are more effective than non-surgical options, challenging long-held beliefs in the medical community.
- * A systematic review was conducted by searching databases like PubMed and Cochrane to gather high-quality, peer-reviewed research from 2015 to 2023, focusing on the pathogenesis, management, and treatment of DCM.
Article Synopsis
- * A systematic review of studies from 2007 to 2022 showed that RA techniques resulted in more accurate screw placements compared to FG methods, with significant findings based on the Gertzbein-Robbins classification.
- * While RA techniques appeared to reduce radiation dosage per case, they were associated with longer operating times; FG techniques were quicker but resulted in higher radiation exposure.
Article Synopsis
- Intravesical Bacillus Calmette-Guérin (BCG) therapy is the preferred treatment for superficial bladder cancer, enhancing the immune response against cancer cells.
- While BCG therapy is effective, it can lead to local or widespread infections, including rare cases of vertebral osteomyelitis in older males.
- This paper discusses an 84-year-old man's case of L5-S1 osteomyelitis and aims to inform spine surgeons about recognizing this rare complication related to BCG therapy.
Background: Although patients with COVID-19 have a higher risk of acute ischemic stroke (AIS), the impact on stroke outcomes remains uncertain.
Aims: To determine the clinical outcomes of patients with AIS and COVID-19 (AIS-COVID+).
Methods: We performed a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines.
Article Synopsis
- The study investigates the relationship between lumbar spine surgery history and paralumbar muscle health as assessed through MRI measurements.
- It employs a retrospective cohort design, comparing MRI-based parameters like cross-sectional area and muscle grading between patients who have undergone spine surgery and those who haven’t.
- Analysis involved 615 patients, ultimately matching 89 patients with surgery history to 89 without, showing no significant differences in demographic variables.
Introduction: The management of spinal neoplasia consists of surgical, radiation, and systemic options. Little data exist to guide management based on overall health status, which is particularly challenging when patients who could benefit from surgery may be too frail for it. This study's objective was to evaluate the 5-Item Modified Frailty Index (mFI-5) as a predictor of 30-day morbidity in patients undergoing instrumented resection for metastatic extradural spinal tumors.
View Article and Find Full Text PDFDegenerative cervical myelopathy (DCM) is the most frequent cause of spinal cord dysfunction and injury in the adult population and leads to significant loss of quality of life and economic impact from its associated medical care expenditures and loss of work. Surgical intervention is recommended for patients manifesting progressing neurological signs and symptoms of myelopathy, but the optimal management in individuals who have mild and clinically stable disease manifestations is controversial. Understanding the natural history of DCM is, thus, important in assessing patients and identifying those most appropriately indicated for surgical management.
