SAGITTAL ALIGNMENT
This describes the alignment of the skeletal system in the sagittal plane. Both the global and regional levels of sagittal alignment should be considered:

Global alignment is the sagittal profile of the skeletal system: head, spine, pelvis, and legs.
Regional alignment is the sagittal profile of the spine and pelvis.
It is also important to recognize the difference between sagittal alignment and sagittal balance:

Alignment describes static, upright posture (standing).
Balance implies dynamic upright motions (gait and other activities of daily living).
Alignment of the skeletal system in the sagittal plane can be affected by several factors, including pelvic anatomy, body mass, degeneration, instability, deformity, and previous surgeries. Normal alignment is patient-specific.

Sagittal alignment of the spine may be restored through increasing segmental lordosis. In OLIF procedures, a large lordotic cage is placed on the vertebral apophysis, which is the strongest part of vertebral body, minimizing the risk of graft subsidence.
