Understanding the influence of cage and instrumentation strategies with oblique lumbar interbody fusion for grade I spondylolisthesis - A comprehensive biomechanical modeling study.

Background Context: Proper implant selection and placement in oblique lumbar intervertebral fusion (OLIF) are essential to achieve the best possible results for the patient. Key factors such as interbody cage length, height, angle, and material must all be carefully considered to achieve the intended results and minimize complications. Significant challenges remain in selecting the appropriate cage parameters to control spinal alignment while minimizing subsidence risk.
