The Kambin’s triangle is defined as a right triangle over the dorsolateral disc. Paraplegia following a thoracolumbar transforaminal epidural steroid injection. In total, the contrast agent diffused into the anterior epidural space in 21 The calculations of the area were made by measuring the exiting nerve root, the superior border of the caudal vertebra, and the ,ambin articulating facet-the borders of the Kambin’s Triangle.

Yeung, MD and Christopher A. They recommended that measuring this distance during preoperative MRI studies may allow surgeons to choose more optimal approaches.

After 4 weeks, the patient satisfaction index was measured on a 5-point scale, as follows: Clin Orthop Relat Res.

Microstructural changes are coincident with the improvement of clinical symptoms in surgically treated compressed nerve roots. Kambin P, Savitz MH. As a result, two cases of injecting the contrast agent into the intervertebral disc were found in the subpedicular approach, but no cases in the Kambin’s triangle approach.


Journal List Ann Rehabil Med v. Then, trianglw needle was located medially in the 5 o’clock direction of the upper pedicle at the anteroposterior view, without further advancement and in the posteroinferior of the intervertebral foramen at lateral view. Showing of 32 references. Kambin’s Triangle is the site of surgical access for posterolateral endoscopic discectomy.

Suggested causes include inflammatory changes around nerve root, venous congestion and hematogenous disability. It presents less scarring, less complications and a faster recovery, thereby speeding up the time for patients to return to work 2,3,4,5,6,7,8.

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

Scott E GlaserFrank J. MurthyTimothy P.

Partial fecetectomy to widen transforaminal space. In the subpedicular approach, the needle is located in the anterior of the intervertebral foramen crossing the nerve root.

Diffusion scope of the contrast agent In the subpedicular approach, on lateral view, the contrast agent diffused only to the hriangle epidural space in 18 patients This area is called “the safe triangle,” because the space mainly contains only the spinal nerve and vessels.


As mentioned before, the preganglionic approach may be more effective for patients with herniated intervertebral disc, because the needle can be placed closer to the nerve root compressed by the herniated intervertebral disc.

Cadaveric Analysis of the Kambin’s Triangle.

They used postoperative MRI to confirm the extent of resection. Kamgin 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.

At the time of open dissection, there was no ENR injury from the wire insertion. National Center for Biotechnology InformationU. Introduction Kambin’s Triangle is a right triangle over the dorsolateral disc. Juli, 81 7pp — He successfully treated more than 2, patients suffering from disc herniations.

In their series of patients, none had ENR injury. Both groups did not present nerve root damage as a complication, and injection into the intervertebral disc was found in two cases of the subpedicular approach. All kambon were performed using C-arm KMC See all authors and affiliations.
