Anterior Lumbar Interbody Fusion Of The Lumbar Spine, Lateral View

Description

Lumbar vertebral bodies are seen in lateral profile with a single interbody cage seated within the disc space between two adjacent lumbar vertebrae. The cage spans from the anterior margin of the intervertebral space toward the posterior endplate region, centered in the sagittal plane to restore disc height and segmental lordosis. Superior and inferior vertebral endplates form the bony boundaries of the fusion level, while the anterior cortex of each vertebral body outlines the approach corridor typical of an anterior lumbar interbody fusion (ALIF). Alignment is the point. Anterior lumbar interbody fusion is selected when discogenic low back pain, degenerative disc disease, low grade spondylolisthesis, or recurrent disc pathology demands disc space reconstruction and indirect foraminal decompression without posterior muscle dissection. A lateral view clarifies how the interbody cage engages the apophyseal ring region and why subsidence becomes more likely when endplate preparation violates the stronger peripheral bone, a practical teaching detail for both spine surgery trainees and implant design discussions. The perspective also helps correlate implant position with potential complications, since the ALIF corridor traverses the anterior lumbar spine near the great vessels, and a cage placed too posterior risks proximity to the spinal canal and traversing nerve roots. Orthopedics and neurosurgery programs can drop this illustration into lectures on lumbar fusion techniques, interbody device selection, and sagittal balance planning. Medical publishers will find it well suited for operative atlases, informed-consent graphics, and peer-reviewed manuscripts discussing interbody cage sizing, placement, and fusion biomechanics in the lumbar spine.
