1. Spine Region & Targeted Level

Select the primary location where symptoms and radiological findings originate.

Cervical Spine (Neck & Arm) — Single Level (e.g., C5/6 or C6/7)Single-level cervical disc herniation or nerve root compression.

Cervical Spine — Two Adjacent Levels (e.g., C5/6 and C6/7)Two contiguous cervical disc herniations or stenotic levels.

Lumbar Spine (Lower Back & Leg) — Single Level (e.g., L4/5 or L5/S1)Single-level lumbar disc herniation or symptomatic disc degeneration.

Lumbar Spine — Multi-level (3 or more levels affected)Generalized multi-level lumbar degenerative disc disease.

Understanding Motion Preservation vs. Spinal Fusion

Artificial Disc Replacement (ADR)

Motion-preserving total disc replacement inserts a bio-compatible artificial joint into the disc space following anterior micro-decompression.

Preserves natural segmental flexion, extension, and rotation.
Reduces kinematic stress on adjacent spinal levels (adjacent segment disease protection).
Facilitates early physical rehabilitation and active lifestyle return.

Spinal Fusion (ACDF / Interbody Fusion)

Spinal fusion stabilizes the affected segment using bone graft and interbody cages, converting the mobile disc space into solid bone.

Indicated when significant facet joint osteoarthritis or spondylolisthesis is present.
Provides structural stability when facet joints can no longer support movement.
Eliminates painful micro-motion across arthritic facet joints.
