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.

Recently, the diffusion tensor imaging technique has been used for the structural and functional diagnosis of lumbar nerve damage before and after surgery. The Kambin’s triangle approach is as efficacious as the subpedicular approach for short-term effect and offers considerable advantages i.
Parviz Kambin was the first surgeon, who described the transforaminal endoscopic access to herniated discs. In their series of patients, none had ENR injury.
All procedures were done by the same author; photographs were taken before and after administration of the contrast agent and 2 cc of the agent 0. Ralf Triajgle and Dr. Surgical technique, outcome, and complications in consecutive cases.
Lumbar Region Search for additional papers on this topic.
Then surgeon moves needle on the X2, X3, and X4 point to avoid touching the exiting nerve root. Thus, in this study, the final target site of injection was determined to be the posterior inferior at the lateral view Fig.
Percutaneous Transforaminal Endoscopic Spine Surgery: Introduction – Part 1
Find articles by Byeong Ju Lee. In an experienced surgeon’s hands, the endoscopic foraminal approach can be utilized for most lumbar disc herniations and for the diagnosis and treatment of degenerative conditions of the lumbar spine.
Minimally invasive surgical options that do not have the inherent approach-related morbidity are possible with the endoscopic foraminal portal, therefore endoscopic diagnosis and surgical intervention can be considered for painful spinal conditions that were previously operated on only when there was evidence of nerve damage.
At the time of open dissection, there was no ENR injury from the wire insertion. This is an open access article licensed under the terms of Creative Commons Attribution 4. Transforaminal percutaneous endoscopic lumbar siscectomy for upper lumbar disc herniation: Find articles by Soo Kyoung Cho.
Kaye Pain physician No correlation was found between the other variables tested and therapeutic effect. There are three approaches for PELD: Effectiveness of transforaminal epidural steroid injection by using a preganglionic approach: A prospective, randomized, controlled, double-blind study.
Lumbar Region Steroids Lumbar spinal canal stenosis. 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.
Kambin’s Triangle Approach of Lumbar Transforaminal Epidural Injection with Spinal Stenosis
Open in a separate window. Subpedicular approach All patients were in the prone position and were supported by pillows under the abdomen to reduce lumbar lordosis.
Comparison of the numeric rating scale NRS between the two groups was conducted by repeated measures analysis of variance ANOVAand Bonferroni’s correction was applied post-hoc. Kambin’s triangle, Lumbar, Transforaminal, Stenosis.
After the final location of the needle was secured, 1 cc of non-ionic contrast agent was administered to observe diffusion location and scope of the contrast agent, and then 2 cc of the prepared agent 0. Evaluation of lumbar transforaminal epidural injections with needle placement and contrast flow patterns: According to Murthy et al. They did not describe about the type of anesthesia used during the surgery.
All patients were in the prone position and were supported by pillows under the abdomen to reduce lumbar lordosis. Patient consent Not applicable. Financial support and sponsorship None. 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. In the Kambin’s triangle approach, 12 He received his doctorate degree in medicine from Tehran University Faculty of Medicine in Find articles by Yongbum Park.
In a series of trials on anatomical specimens, he identified a working area within the intervertebral foramen through which the spinal canal can be safely accessed. In the subpedicular approach, on anteroposterior epidural contrast, the contrast agent diffused by 1.

In the subpedicular approach, the agents are injected at the exit zone as the distal site of the nerve root canal; occasionally the agents cannot be delivered into retrodiscal area, as the entrance zone or proximal area is passing through the stenosis area.
Transforaminal endoscopic spinal surgery. Diffusion tensor imaging with quantitative evaluation and fiber tractography of lumbar nerve roots in sciatica. By using logistic regression, correlations between success of treatment and several variables method of injection, age, gender and period of prevalence were analyzed.
J Spine Res ;4: The hypotenuse is the exiting nerve; the base is the caudad vertebral body; and the height is the traversing nerve root. In the preganglionic approach, it is possible to inject agents at the entrance and middle zone as the main areas of nerve entrapment by injecting at the retrodiscal area of the entrance zone, as proximal area of the targeted nerve root e.
