“…Lumbar intervertebral foramen height is greater at L3/4, L4/5, smallest at L1/2, smaller at L5/S1; lumbar L1-S1 the minimum sagittal diameter of the intervertebral foramen tends to increase and then decrease, being smallest at L1/2 and largest at L4/5. Vialle [15] measured the lumbar segments of eight male adult specimens The mean value of the maximum longitudinal diameter of the spinal ganglion was 13.25 mm and the mean value of the minimum sagittal diameter of the spinal ganglion was 7.05 mm, which is similar to that of this paper. The findings were consistent.…”

Background: Based on CT images of the thoracolumbar intervertebral foramen and its surrounding parameters, and analyzing the intervertebral foramen morphology and the correlation between the measured parameters, to provide an anatomical basis for clinical minimally invasive transvertebral surgery. Materials and methods: Ten fresh adult cadaveric specimens (32-50 years old) with bilateral (T1-S1) spinal segments were selected for a total of 20 sides, a total of 340 intervertebral foramen, were measured with vernier calipers in the Department of Anatomy, Inner Mongolia Medical University. The intervertebral foramen height, the minimum sagittal diameter of the foramen, the width of the spinal ganglion, the sagittal diameter of the spinal ganglion and the sagittal diameter of the intervertebral foramen were measured. This study was reviewed and approved by the local Ethics Committee. Results: The results of the minimum sagittal diameter of the T9-10~L5/S1 intervertebral foramen were 6.

“…For Kambin's triangle measurements, the current study showed results similar to those of the Thai population for the vertical measurements and the Brazilian population for the lower level vertical measurements (L1 and L2). Also, similar results were observed for the diagonal measurements in the current study, Brazilian (Vialle, Vialle, Contreras, & Jacob, 2015), and…”

Introduction: As a result of the increased utilization of neurosurgical arthroscopic techniques, investigations into population and sex-specific trends of anatomical considerations have become increasingly important. This study aimed to investigate and describe aspects of the neuroanatomical morphometry of lumbar spines in a cadaveric and magnetic resonance imaging (MRI) sample. Materials and Methods: Twenty white adult (>18 years) cadavers (9 males; 11 females) were obtained under Ethical clearance. The lumbar regions were dissected and the position of the dorsal root ganglion (DRG) and dimensions of Kambin's triangle were determined. Twenty-six black adult (>18 years) MRI scans (17 males; 9 females) were obtained from an Academic Hospital and were used to determine the dimensions of the neural foramen and the DRGs within. Results: The ganglia were mostly at the midline of the caudal pedicle. Similar to previous studies, the diagonal measurement from Kambin's triangle was the largest and the vertical measurement the shortest. Skeletal and soft-tissue measurements indicated distinct trends when moving caudolaterally in the spine. Soft-tissue parameters from the current study were within the upper limits of those from previous studies, whereas skeletal parameters were in agreement with those reported by previous authors. Conclusions: Results from this study suggest a variation of certain parameters between studies with varying population groups and therefore supports the need for and the importance of possible population-specific trends of anatomical parameters considered during surgical procedures.

“…for this reason, pain control is an important part of conservative LDH treatment until spontaneous resolution. 5 Conservative forms of treatment include the use of analgesics and anti-inflammatory agents, physical therapy, manual therapies, and epidural blocks. epidural steroid injections have proven to be a low-risk alternative in some patients for whom other treatments have not been effective.…”

“…8 Additionally, diffusion of the drug in the anterior part of the dural sac is more effective 9 due to the relationship with the nociceptive fibers in the anterior region of the root and the dorsal ganglion. 5 Transforaminal epidural injection can be an effective tool in the treatment of sciatica in the short-term acute phase, with the potential to reduce costs for society by reducing time away off work and lost productivity.…”

Objective: To determine the efficacy of anesthetic transforaminal nerve root block in patients with sciatica secondary to lumbar disc herniation through a prospective observational study. Methods: The study included 176 patients from a private clinic undergoing transforaminal injection performed by a single spinal surgeon. The patients were assessed after two weeks, three months and six months regarding to the improvement of the pain radiating to the lower limbs. In case of persistent symptoms, patients could choose to perform a new nerve root block and maintenance of physical therapy or be submitted to conventional microdiscectomy. Results: By the end of six-month follow-up of the 176 patients, 116 had a favorable outcome (95 after one block and 21 after two blocks), and only 43 required surgery. Conclusion: The results of our study suggest a positive effect of transforaminal block for the treatment of sciatica in patients with lumbar disc herniation.
