Background: Intradural disc herniations (IDHs) are rare occurrences (0.26-0.30%), and most frequently involve the lumbar spine at the L4-L5 level. Here, we present a patient with an L1-L2 IDH and reviewed the current literature.
Case Description: A 65-year-old female presented with the acute onset of bilateral paraparesis accompanied by urinary dysfunction. The lumbar MRI showed a mass at the L1-L2 level with caudal migration, accompanied by a positive "hawk-beak" sign. At surgery, consisting of a L1-L2 laminectomy, a large IDH was encountered responsible for marked cauda equina/root compression. Postoperatively, the patient immediately fully recovered. The literature we identified cited just seven similar studies of L1-L2 IDH.
Conclusion: In a 65-year-old female, an IDH was anticipated at the L1-L2 level due to the combined MR findings of a large L1-L2 mass with caudal migration and the positive "hawk-beak" sign.

Background: Endoscopic procedures nowadays are successful, minimally invasive, and safer, with fewer intraoperative and postoperative complications and shorter hospital stays. Kambin's triangle (KT) is the three-dimensional configuration that is used as a transforaminal anatomical corridor for epidural steroid injections and endoscopic surgeries for various lumbar pathologies. This study aims to estimate the dimensions of KT and diameter of the cannula for the transforaminal surgical approaches using KT in the Chhattisgarh population.

Background: Maternal and neonatal mortality rates remain alarmingly high in low-resource settings, with infections acquired during childbirth contributing significantly to this burden. Effective infection control measures at delivery points are crucial for mitigating these risks. This observational study aimed to assess the quality of infection control practices in delivery points in a tribal district of Maharashtra, India.

Argonaute proteins are active throughout the lifetime in a variety of organisms and they bind to small RNAs (sRNAs) to regulate gene expression. The Argonaute proteins of vertebrates can be classified into two clades: the Ago clade and the Piwi clade. Both clades have N, L1, L2, PAZ, MID and PIWI domains.

Background: Prior studies have linked sarcopenia and fat infiltration in paraspinal muscles with lumbar pain, spinal pathology, and adverse postoperative outcomes in lumbar spine surgery. A recent magnetic resonance imaging (MRI)-based method for assessing muscle health, incorporating parameters such as Goutallier Classification (GC) and the Paralumbar Muscle Cross-Sectional Area to Body Mass Index ratio (PL-CSA/BMI), has shown that higher muscle grades correlate with significant improvements in patient-reported outcomes. Despite these advancements, there is limited research on the associations between paralumbar muscle health and factors such as age, BMI, walking tolerability, and spondylolisthesis.

- The study aimed to analyze how changes in upper lumbar lordosis after spinal fusion affect the alignment of unfused lower lumbar segments in patients with Adolescent Idiopathic Scoliosis.
- A retrospective review was conducted on 158 patients who underwent posterior spinal fusion, focusing on various spinal measurements and using MATLAB for 3D calculations.
- Results indicated that increased upper lumbar lordosis influenced the lordotic shape of distal unfused segments, with varying impacts based on the specific levels of fusion, while overall sagittal alignment remained stable.
