Early NRS Leg and Back Thresholds Predict Clinical Recovery After MIS Transforaminal Lumbar Interbody Fusion for Degenerative Spine Disease. Academic Article uri icon

Overview

abstract

  • 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) 1 year post-surgery. BACKGROUND: Early identification of patients at risk of failing to achieve ODI-MCID is crucial for early intervention and improved postoperative counseling. Currently, no specific thresholds guide patient follow-up for optimal recovery. MATERIALS AND METHODS: The assessment included demographic information, surgical details, and patient-reported outcome measures (PROMs). PROMs were collected postoperatively at 2-week, 6-week, and 12-week time points, as well as at 6 and 12 months. RESULTS: The study included 166 patients, with 34% failing to achieve ODI-MCID at 1 year. Early VAS back and leg scores were found to be significant predictors of ODI-MCID achievement. The optimal thresholds identified were 2.25 for early VAS back and 4.25 for early VAS leg. A rerun regression identified the thresholds as independent predictors of ODI-MCID, with odds ratios of 0.31 for both measures. CONCLUSION: VAS back and leg score thresholds at 6 to 12 weeks can predict ODI-MCID achievement 1 year after MIS TLIF. Patients exceeding the identified thresholds may be at risk of failing ODI-MCID and should be monitored closely. LEVEL OF EVIDENCE: Level three.
