The hypotenuse is the exiting nerve; the base is the caudad vertebral body; and the height is the traversing nerve root. from publication: Kambin’s Triangle. To compare the short-term effect and advantage of transforaminal epidural steroid injection (TFESI) performed using the Kambin’s triangle and. Objective The aim of this study was to conduct a randomized, blinded, prospective outcome study on the short-term benefits of the Kambin triangle vs. the.

Conclusion Understanding the Kambjn Triangle will assist surgeons in the minimally invasive approach to spinal surgeries, with potentially safe placement of interbody cages through this strategic space. They suggested using a partial superior facetectomy to avoid ENR injury [Figure 2].

Thus, in this study, the final target site of injection was determined to be the posterior inferior at kabmin lateral view Fig. Menno Iprenburg who is one of the most dedicated surgeons in this field. Clin Orthop Relat Res.

Anatomical relationship between Kambin’s triangle and exiting nerve root

Transforaminal and interlaminar approaches are mainly used for intracanal disc herniation. Thus, it may prick the spinal nerve root during injection because it is difficult for the needle to be located in the anterior epidural space through the safe triangle in severe spinal stenosis, epidural fibrosis, and sunken degenerative intervertebral disc region.

Yeung developed an endoscopic system that featured beveled and slotted cannulas with the open end kambni toward the dorsal foramen, exposing the epidural space and the base of the disc herniation in the same endoscopic view Figure 3.

If you continue to use this site we will assume that you are happy with it. The frequency of complications during the procedure and the effect of TFESI at 2 and 4 weeks after the procedure between the two groups were compared.


Spine Phila Pa ; Matthews first described the foraminal ligament as the “door” to the foramen. The short-term treatment effects significantly declined in both groups at 2 and 4 weeks after the procedure. Anatomic assessment of variations in Kambin’striangle: At L-5, S-1, less room is present in the foramen, and a lateral facetectomy may be necessary if a high and narrow Ilium is present.

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 Find articles by Yongbum Park. Schematic description of the “Kambin’s triangle”. J Med Invest ; Statistical analyses Gender, BMI, period of prevalence, age, targeted nerve root and diffusion of the contrast agent were compared between the two groups using the chi-square test, Fisher’s exact test, and Mann-Whitney U method.

The exclusion criteria were: Root cause analysis of paraplegia following transforaminal epidural steroid injections: The relevant lumbar part was identified by using the Scotty dog shadow oblique view. In this method, the injection needle is progressed towards the safe triangle under the inferior surface of the pedicle to locate the superolateral spinal nerve related to symptoms.

When the needle reached the final location, an aspiration text test was conducted to check for blood detection, and 1 cc of non-ionic contrast agent was administered under real-time fluoroscopy, to identify whether the agent was injected into the anterior epidural space.

Other two patients were excluded because it was difficult for them to visit the hospital regularly. Surgical technique, outcome, and complications in consecutive cases. Converting from a translaminar to an interlaminar approach is a reasonable option. Patient consent Not applicable. Many clinical reports have indicated that PELD is preferable to conventional open techniques.

He has been recognized by the College of Physicians of Philadelphia and his work in part has been exhibited in the Mutter Museum. Pain was assessed before treatment and 2 and 4 weeks after treatment, to compare the short-term therapeutic effects of the two approaches.

It presents less scarring, less complications and a faster recovery, thereby speeding up the time for tdiangle to return to work 2,3,4,5,6,7,8. Mt Sinai J Med. Figure 3b From Regan JJ.

Cadaveric Analysis of the Kambin’s Triangle.

MausCurt L Behrns Pain medicine This area is called “the safe triangle,” because the space mainly kambjn only the spinal nerve triagnle vessels. Lumbar spinal stenosis may induce radiating pain in the lower limbs through narrowed intervertebral foramen by a herniated intervertebral disc due to degenerative changes and thickening of the ligamentum flavum, zygapophysial joint and surrounding soft tissues.

Transforaminal epidural steroid injections in lumbosacral radiculopathy: Ji Woong ParkM. Finally, line 5 was drawn bisecting 1 and 2, and, likewise, line 6 bisecting 3 and 4. This relatively conservative posture was due to the inherent morbidity of traditional posterior surgery that must violate and alter the important function of the muscles and facets of the posterior spinal column. Clinical succes of transforaminal endoscopic discectomy with foraminotomy: The endoscope and instruments are introduced through a cannula between the kzmbin and exiting nerves in an area known as Kambin’s Triangle Figure 2.
