Many disc herniations, however, are not the result of an acute event, but an accumulation of several insults to the spine that lead to painful degeneration, annular tears, and eventual disc herniation.

Kambin was born in Tehran, Iran on May 21, Fluoroscopically guided lumbar transforaminal epidural steroid injections in degenerative lumbar stenosis: BenyaminAlan D. Arch Phys Med Rehabil. Illustration by David Azarello. Showing of 17 extracted citations. Yriangle line was drawn halfway between the farthest medial 2 and farthest lateral 3 points on the pedicle.

Kambin Award

Multiple logistic regression analyses were performed to evaluate the relationship between possible outcome predictors Kambin’s triangle or subpedicular approach, age, duration of symptoms and sex and the therapeutic effect. B The anterior-posterior view showing the proper location of the needle at the base of pedicle. Surgical morbidity has, therefore, limited the use of surgery as an early treatment option in disc degeneration and herniation.

Published online Dec The sex ratio, duration of pain, body mass index BMInerve root as cause and period of prevalence are presented in Table 1. Note the more cephalad the disc, the larger the foraminal portal. The approach could an alternative to the subpedicular approach in severe spinal stenosis, epidural fibrosis and sunken degenerative intervertebral disc lesion, when it is hard to place the needle in the anterior epidural space through the safe triangle.


Conclusion The Kambin’s triangle approach is as efficacious as the subpedicular approach for short-term effect and offers considerable advantages i. Preganglionic approach to transforaminal epidural steroid injections. The subjects of this study were patients who visited the Department of Rehabilitation Medicine for lumbar nerve root pain between July 1 and June 31 Morphology of the human internal vertebral venous plexus: This method and technology is a further development of the original access technique.

InMirkovic et al. Abstract Objective To compare the short-term effect and advantage of transforaminal epidural steroid injection TFESI performed using the Kambin’s triangle and subpedicular approaches. Evaluation of lumbar transforaminal epidural injections with needle placement and contrast flow patterns: They are treading new paths for spinal endoscopy.

Thus, surgery was usually not recommended for herniations without neurologic deficits. Other severe complications were not shown.

Intraforaminal triang,e of the great anterior radiculomedullary artery artery of Adamkiewicz: They suggested using a partial superior facetectomy to avoid ENR injury [Figure 2]. When the agent diffused into the epidural space, the agent diffusing from the injected vertebral body by blocking the needle in the cranial-caudal direction and diffusion to the anterior or posterior epidural space was analyzed on the lateral view.


Kambin’s Triangle Approach of Lumbar Transforaminal Epidural Injection with Spinal Stenosis

Diffusion tensor imaging of radiculopathy in patients with lumbar disc herniation: Radiographic analysis of sagittal plane alignment and balance in standing volunteers and patients with low back pain matched for age,sex, and size. Cadaver dissection of the foramen from L2-S1 demonstrates excellent access to the postero-lateral portion of the disc through Kambin’s triangular zone.

As for intravascular injection, four cases were found in the conventional subpedicular approach and three cases were found in the Kambin’s triangle approach, with no significant difference between the two Table 3.

Topics Discussed in This Paper. However, the treatment effects were not clearly different from those of the subpedicular approach. They recommended that the guide needle should be attached to the lateral aspect of the superior facet for the insertion of dilators and cannula before accessing the annulus. In experimental test series on specimens, he identified a workspace within the intervertebral foramen, through which the spinal canal can be accessed safely.
