Are Patient-Reported Outcomes of Minimally Invasive Transforaminal Lumbar Interbody Fusion Influenced by Preoperative Mental Health?

Abstract

Study design: This was a retrospective review of prospectively collected data. Objectives: Few studies have described the relationship between mental health and patient-reported outcome measures (PROMs) after minimally invasive spine surgery. Prior studies on open surgery included small cohorts with short follow-ups. Methods: Patients undergoing primary minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for degenerative pathology were retrospectively reviewed and stratified by Short Form (SF-36) Mental Component Summary (MCS): low MCS (<50, n = 436) versus high MCS (≥50, n = 363). PROMs assessed were back pain, leg pain, North American Spine Society Neurogenic Symptoms, Oswestry Disability Index, SF-36 Physical Component Summary, and MCS. Satisfaction, expectation fulfilment, and return to work (RTW) rates also were recorded at 1 month, 3 months, 6 months, and 2 years. Results: Preoperative MCS was 39.4 ± 8.6 and 58.5 ± 5.4 in the low and high MCS groups, respectively (P
