Introduction: Disc sequestration is well known as a perforation of the fibrous ring and posterior longitudinal ligament, and migration of the fragment to the epidural space.
Case Report: A 62-year-old man complained of increased pain and hypoesthesia and muscle weakness of the left lower limb that had started 1 month before. Magnetic resonance imaging revealed a tumor-like mass at the L2-3 level on the posterior side of the dura. The fragment was strongly adhered to the dural sac and was resected piece by piece. Disc herniation recognized at L2-3 compressed the left L3 nerve root and was removed. The histopathological diagnosis was consistent with a degenerated intervertebral disc. All symptoms improved after the surgery.
Conclusion: There are few reports about the posterior migrated disc herniation at higher lumbar level. It may be associated with fused segments from L4 to the pelvis due to the previous surgery, which impacted the adjacent segment.

Background: While the line joining the posterior superior iliac spine (PSIS) intersects a relatively stable sacral vertebra, it does not directly facilitate the localization of lumbar interspace or assist in the positioning for neuraxial anesthesia. Our study aimed to explore the potential of the PSIS line as a reference point and to determine its practical applicability in clinical settings.
Methods: We consecutively enrolled pregnant women with gestational ages ranging from 24 to 38 weeks scheduled for magnetic resonance imaging (MRI) examination.

Old thoracolumbar fracture with kyphosis (OTLFK) often results in low back pain, with intervertebral disc degeneration being a significant contributor. We hypothesized that patients with OTLFK exhibit distinct patterns of disc degeneration compared to those with chronic low back pain without kyphotic deformity. This study aimed to investigate the characteristics of disc degeneration in OTLFK patients and explore its association with sagittal spinal parameters and endplate injury.

Background Context: 3D-printed titanium cage designs can incorporate complex, porous features for bone ingrowth and a greater surface area for minimizing subsidence. In a companion study (Part 1), we determined that increased surface area leads to decreased subsidence; however, it remains unclear how increasing the cage surface area, resulting in a smaller graft aperture, influences fusion.
Purpose: We evaluated the effects of surface area of 3D-printed titanium cages and the use of autologous bone grafts on spinal fusion in sheep.

Objective: The purpose of this study was to investigate the feasibility of the use of shear wave elastography (SWE) in comparison to chemical shift encoding (CSE) magnetic resonance imaging (MRI) for the evaluation of multifidus muscle fatty degeneration in patients with chronic low back pain.
Method: Multifidus muscles were evaluated with the CSE-MRI and SWE examinations in control and patient groups. With the in-phase and out-phase sequences in CSE-MRI, signal intensity index (SII), and signal intensity suppression ratio (SISR) values; with the SWE method, shear wave velocity values were determined.
