Lateral Lumbar Interbody Fusion (LLIF) for the Treatment of Adult Spinal Deformity (ASD)

Adult scoliosis (AS) may be defined as a coronal deformity with a Cobb angle >10° in a skeletally mature patient. Although AS can develop from the progression of idiopathic scoliosis (IS) in adolescence, more commonly AS develops as the result of a degenerative cascade later in life that terminates in asymmetric disc collapse, vertebral body wedging, facet degeneration, spondylolisthesis, and rotary subluxation. This degenerative cascade has the potential to lead to spinal stenosis, instability with progressive deformity in the coronal and sagittal planes, loss of lumbar lordosis, and the development of sagittal imbalance. Patient symptoms can include radiculopathy, neurogenic claudication, and back pain [1].

Non-surgical Management of Spondylolisthesis in Adults

Low-grade spondylolisthesis in adults more commonly has an isthmic or degenerative etiology and slip progression is uncommon, with most patients responding to non-operative treatment.
