Spine, Apr 20, triamgle 9pp All procedures were done by the same author; photographs were taken before and after administration of the trkangle agent and 2 cc of the agent 0. In this context, the purpose of this study was to compare the subpedicular approach and the approach using Kambin’s triangle in transforaminal epidural block performed in patients with spinal stenosis complaining of lumbar radicular pain, and to investigate the short-term effects and possible complications during injection.

Endoscopic spine surgery is evolving rapidly due to improvements in surgical technique, trianglle design, and instrumentation. Transforaminal epidural steroid injections in lumbosacral radiculopathy: D A small amount of contrast is used to confirm epidural spread.

Clinical succes kmabin transforaminal endoscopic discectomy with foraminotomy: Conflicts of interest There are no conflicts of interest. 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. As kwmbin 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.

Journal List Ann Rehabil Med v. The main trunk of triagle AKA enters the medial spinal canal through either the mid or the rostral portion of the foramen. This concept is widely accepted for not only PELD but also epidural injection and interbody fusion techniques.

Cadaveric Analysis of the Kambin’s Triangle.

Clinical result of PELD via transforaminal approach under general anesthesia. The area of this right triangle currently serves as a strategic site of posterolateral, minimally invasive access to triangl nerve root for delivery of epidural steroid injections. He has been recognized by the College of Physicians of Philadelphia and his work in part has been exhibited in the Mutter Museum.

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

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. SpineUniverse does not provide medical advice, diagnosis or treatment. Partial fecetectomy to widen transforaminal space. Kambin’s triangle is defined as a right triangle over the dorsolateral disc.

InKambin introduced endoscopic intervertebral discectomy by posterolateral approach, defining the Kambin’s triangle as the site to approach the intervetebral disc. Together with several colleagues, he assisted in the establishment of the International Society for Minimal Intervention in Spinal Surgery in and was elected the first president of the society in No published studies have been performed to characterize the dimensions of the Kambin’s Triangle. Kaye Pain physician Preganglionic approach to transforaminal epidural steroid injections.


In a retrospective study, Murthy et al. C The lateral radiography should also be used while advancing past the SAP to minimize the risk of the penetration until the needle tip is at the posterior and inferior aspect of intervertebral neural foramen.

Article Access Statistics Viewed: Full-endoscopic interlaminar and transforaminal lumbar discectomy versus conventional microsurgical technique: The agent was considered to be sufficiently injected to the region, as the agent diffused to the anterior epidural space on the anteroposterior and lateral view.

As for the effects of epidural nerve blockage, Delport et al. Percutaneous endoscopic lumbar discectomy for recurrent disc herniation: Complications included 1 disc recurrence, but there were no nerve root injuries and infections.

He successfully treated more than 2, patients suffering from disc herniations.

He received trangle doctorate degree in medicine from Tehran University Faculty of Medicine in 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.
