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.

Multiple logistic regression analyses were performed to evaluate the relationship between possible outcome predictors Kmbin triangle or subpedicular approach, age, duration of symptoms and sex and the therapeutic effect.

A In oblique view, needle tip lies directly inferior to the pedicle and inferolateral to the pars interarticularis.

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. Minim Invasive Neurosurg ; 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.

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

Introduction Kambin’s Triangle is a kambni triangle over the dorsolateral disc.

Morphology of the human internal vertebral venous plexus: Nerve root pricking during injection showed significant differences: Both patients did not develop complications, such as diskitis. Surgical morbidity has, therefore, limited the use of surgery as an early treatment option in disc degeneration and herniation.

Then, the 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. Comparison of the temporary diagnostic relief of transforaminal epidural ste roid injection approaches: This approach advocated a more horizontal trajectory to the disc and visualization of the epidural space.

He has been recognized kakbin the College of Physicians of Philadelphia and his work in part has been exhibited in the Mutter Museum. Diffusion scope of the contrast agent In the subpedicular approach, on lateral view, the contrast agent diffused only to the anterior epidural space in 18 patients Therefore, we finally placed the needle in the posteroinferior of the intervertebral foramen on the lateral view. Small pituitary rongeurs are used for visualized posterior fragmentectomy.

The dorsal muscle column, if compromised as part of the surgical exposure, may be partly responsible for spinal instability and failed back surgery syndrome FBSS. The hypotenuse is the exiting nerve; the base is the caudad vertebral body; and the height is the traversing kambi root. Based on all those aspects, Dr. Conclusion Understanding the Kambin’s Triangle will assist surgeons in the minimally invasive approach to spinal surgeries, with potentially safe placement of interbody cages through this strategic space.

Kambin P, Savitz MH. The canal is divided into the entrance, middle and exit zone. Conflicts of interest There are no conflicts of interest.

The spinal levels of diffusion of the contrast agent in the epidural space were measured in the cranial-caudal direction and recorded at the upper endplate, middle of the vertebral body and low endplate of the vertebral body.

Forty-two patients with radicular pain from lumbar spinal stenosis were enrolled.
