Sagittal balance is an important concept in spinal coronal and kyphotic deformity correction. Sagittal alignment/lumbar lordosis is increasingly recognized and discussed in terms of surgical outcomes. ⋯ This concept is no longer associated only with deformity. Spine surgeons have learned that sagittal alignment/lumbar lordosis is very important even in 1-level or 2-level interbody fusion procedures, and that it can be attained, maintained, or lost during any procedure, resulting in complications.

Researchers are seeking ways to heal bone better and faster. Cellular grafts can accelerate bone healing and promote bone formation. Immediately after injury, blood clot formation yields inflammatory cells; an influx of mesenchymal stem cells (MSCs) and osteogenic cells follows. ⋯ Osteoinduction stimulates stem cells to differentiate into osteoblasts and promotes cell migration. Osteoinductive agents include demineralized bone matrices () and bone morphogenetic proteins, which are extremely potent but are associated with risks and high costs. Amniotic tissue is relatively unregulated and has strong anti-inflammatory effects but has not been well studied in relation to bone formation and healing.
