2026
Here, we present a protocol to perform full-endoscopic trans-Kambin triangle lumbar interbody fusion (KLIF). The protocol utilizes a posterolateral approach via Kambin’s triangle for safe expandable cage insertion and neural decompression while preserving dorsal facet structure and minimizing soft tissue trauma.

Trigonometry of Right Triangles

In a right triangle, trigonometric functions establish specific ratios that describe the relationship between the lengths of the triangle's sides and its acute angles. These relationships are foundational in understanding the structure of right-angled geometry. The sine function quantifies the proportion of the side opposite a given angle compared to the triangle's hypotenuse. In contrast, the cosine function expresses how the side adjacent to the angle relates to the hypotenuse in terms of...

Expanding a binomial expression such as (a + b)n results in a predictable sequence of terms that can be systematically derived using Pascal’s Triangle. This triangular array of numbers plays a central role in understanding and computing the coefficients of binomial expansions.Pascal’s Triangle is constructed such that each row corresponds to the coefficients of a binomial raised to a power. The topmost row, known as the zeroth row, corresponds to (a + b)0, and each successive row gives the...

This procedure performs long-lasting in vivo intracellular recordings from single neurons during physiologically relevant cerebral states and after complete abolition of ongoing electrical activities, resulting in an isoelectric brain state. The physiological constants of the animal are carefully monitored during the transition to the artificial comatose condition.

Elastin-like polypeptides are stimulus-responsive biopolymers with applications ranging from recombinant protein purification to drug delivery. This protocol describes the purification and characterization of elastin-like polypeptides and their peptide or protein fusions from Escherichia coli using their lower critical solution temperature phase transition behavior as a simple alternative to chromatography.
FAQs
Its dimensions are not uniform, and anatomical variations can change the available working space around the disc. Assessing those differences helps clinicians plan instrument trajectories and identify situations in which the corridor may provide less clearance than expected. This planning is important because preserving distance from nearby neural structures can reduce the risk of nerve injury.
The exiting nerve root, traversing nerve root or dural sac, and superior endplate provide anatomical reference points for instrument placement. Their relationships define the usable pathway toward the intervertebral disc. Recognizing these landmarks helps clinicians direct instruments through the posterolateral lumbar spine while avoiding contact with neural structures that border the access route.
Safety depends on the corridor’s dimensions, individual anatomical variation, and the accuracy of the planned instrument trajectory. Fluoroscopic or endoscopic guidance provides visualization during advancement, while anatomical knowledge helps interpret what the instruments approach. Together, these factors support more controlled access to the disc and help limit unintended neural injury.
Clinicians first evaluate the corridor and its surrounding anatomy, including the positions of the nerve roots, dural sac, and caudal vertebral endplate. They then plan an approach toward the disc and advance instruments through the posterolateral window under fluoroscopic or endoscopic guidance. The imaging guidance supports trajectory control throughout the intervention.
The corridor supports transforaminal endoscopic discectomy, percutaneous lumbar interbody fusion, and other minimally invasive spinal procedures. In each application, its value comes from providing a route toward the intervertebral disc through the posterolateral lumbar spine. The specific procedure determines how instruments use the window and what therapeutic objective is pursued.
Understanding the corridor helps clinicians combine anatomical planning with image-guided instrument placement. Accounting for its dimensions and variations can improve procedural planning and support safer access to the disc. In medical practice, this knowledge is especially relevant when selecting or performing minimally invasive lumbar interventions where avoiding nearby neural structures is a central concern.
