Lateral lumbar interbody fusion (LLIF) is a minimally invasive technique that allows access to the lumbar spine from L1/2 to L4/5 for placement of wide interbody devices. This technique is used in the treatment of degenerative conditions, deformity, and infectious, neoplastic, and traumatic thoracolumbar pathology. LLIF allows placement of interbody devices across the apophysis, which leads to powerful coronal deformity correction and indirect decompression from restoration of disk height. Literature shows equivalent to superior outcomes of the LLIF technique to anterior or posterior techniques in the treatment of degenerative conditions while avoiding the complications associated with larger procedures.
