Background: Cavernous hemangiomas are vascular malformations formed by groups of dilated sinusoids, organized in channels with a single layer of endothelium. Cavernous hemangiomas represent only 3% of all intradural lesions, and of these 5-12 % correspond to spinal cord lesions and those of the cauda equina are rare.

Department of Orthopaedics & Spine Surgery, The Second Hospital of Anhui Medical University, No.678 Furong Road, Economic and Technological Development Zone, Hefei, 230601, China.
Article Synopsis
- An unintended dural tear (DT) is the most common complication during lumbar spine surgery, particularly in unilateral biportal endoscopic techniques (UBE), which are increasingly used for degenerative conditions of the lumbar spine.
- A study analyzing data from 608 UBE patients revealed that 3.95% experienced DT, mostly addressed through suture repair or rest, with no severe complications reported.
- The study identified significant risk factors for DT, including older age, lumbar spinal stenosis (LSS), the method of surgery (specifically unilateral laminotomy with bilateral decompression), and whether the surgery was a revision rather than a primary procedure.

Article Synopsis
- Lumbar interbody fusion (LIF) is a popular surgical method for treating spinal deformities and degenerative conditions, which has evolved to become safer and more effective over time.
- The anterior to the psoas (ATP) approach allows surgeons to reach spinal disc spaces without cutting through the psoas muscle, reducing the risk of nerve damage.
- As research supports its safety and effectiveness, the ATP approach may be increasingly used for spinal fusion surgeries in the future.

Department of Orthopedics, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, No. 138, Sheng-Li Road, Tainan, 704, Taiwan.
Article Synopsis
- The study investigates the role of specific pro-inflammatory cytokines (IL-1β, IL-19, IL-20) in directing the differentiation of progenitor cells from intervertebral discs and ligamentum flavum into bone (osteogenesis) or fat (adipogenesis).
- Researchers analyzed cells from patients with degenerative spinal conditions, excluding those with infections or tumors, to understand how these cytokines affect cell differentiation.
- Results showed that IL-1β promotes bone formation while inhibiting fat cell development; in contrast, IL-19 encourages fat cell formation, and IL-20 inhibits bone development while promoting fat cell differentiation.

Department of Orthopedic Surgery, Juntendo University, Tokyo 113-8421, Japan.
Article Synopsis
- The study investigates neurological complications associated with two surgical approaches for lumbar degenerative disease: a conventional lateral approach and a modified lateral approach that involves splitting the psoas muscle.
- The research found that the modified approach significantly reduced the incidence of lumbar plexus injuries, with complications occurring in only 0% of patients in the modified group compared to 10% in the conventional group.
- Intraoperative neuromonitoring results showed that the modified approach led to safer surgical outcomes, allowing access to the intervertebral disc while preserving nerve function.

Department of Orthopaedics, General Hospital of Central Theater Command of PLA, Wuhan, China.
Article Synopsis
- The study investigates different surgical approaches for treating adjacent segment degeneration (ASD) after lumbar fusion, focusing on three methods: percutaneous transforaminal endoscopic discectomy (PTED), posterior lumbar interbody fusion (PLIF) with cortical bone trajectory screw fixation (CBT-PLIF), and PLIF with traditional trajectory screw fixation (TT-PLIF).
- A retrospective analysis involving 46 patients assessed various factors, including surgery time, incision length, recovery time, complications, and pain relief using standardized scales at multiple follow-ups.
- Results showed that PTED had a shorter operation time and faster recovery, while CBT-PLIF and TT-PLIF provided better structural stability and more significant pain reduction at later

Front Surg
January 2023
Department of Orthopaedic Surgery, Ningbo Medical Center Li Huili Hospital, Ningbo, Zhejiang, China.
Article Synopsis
- A study was conducted to compare the effectiveness of two surgical techniques—OLIF (with and without posterior pedicle screw fixation) and MIS-TLIF—in correcting lumbosacral lordosis and improving patient outcomes for spinal issues.
- The research involved 83 patients (ages averaged 65.8) who underwent either surgery, monitoring various factors like operation time, blood loss, fusion rates, and patient-reported pain and disability scores.
- Findings showed that OLIF resulted in shorter operation times and less bleeding compared to MIS-TLIF, with OLIF+PSF demonstrating significantly better lordosis correction, while both techniques effectively restored disc heights.

Department of Neurosurgery, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, Pennsylvania, USA. Electronic address:
Article Synopsis
- Anterior lumbar interbody fusion (ALIF) is a traditional surgery for degenerative spine issues, known for restoring spinal structures but carries risks of severe injuries to surrounding organs and blood vessels.
- *Lateral lumbar interbody fusion (LLIF) is a less invasive alternative but has limitations due to its narrow surgical area and requires repositioning the patient for combined procedures.
- *A new technique combines ALIF and LLIF in one stage with the patient in a lateral position, utilizing a fluoroscopy-based instrument tracking system to enhance surgical precision and reduce reliance on imaging, as demonstrated in a case study of a patient with chronic back pain.

Institute of Chinese Material Medica, China Academy of Chinese Medical Sciences, Beijing, China.
Article Synopsis
- - Danlu tongdu tablets (DLTD) are a Chinese patent medicine commonly used for treating lumbar spinal stenosis and lumbosacral disc herniations but have been linked to liver-related side effects, notably increased ALT and AST levels in some patients.
- - The study assessed the safety of DLTD using acute toxicity tests and chronic toxicity tests over six months on rats, monitoring various health parameters without any fatalities or serious toxicity at lower doses.
- - Mild liver changes were observed at high doses, but these effects were reversible, and transcriptome analysis indicated that DLTD significantly affected cytochrome P450 enzymes, suggesting a potential mechanism behind the observed liver issues.
