Early NRS Leg and Back Thresholds Predict Clinical Recovery after MIS Transforaminal Lumbar Interbody Fusion for Degenerative Spine Disease.

Study Design: This retrospective study included patients who underwent primary one-level minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative lumbar spine conditions.

Objective: To identify early predictors of failing to achieve the Oswestry Disability Index (ODI) minimum clinically important difference (MCID) one-year post-surgery.

Summary Of Background Data: Early identification of patients at risk of failing to achieve ODI-MCID is crucial for early intervention and improved postoperative counseling.
