Instrumented Minimally Invasive Spinal-Transforaminal Lumbar Interbody Fusion (MIS-TLIF): Minimum 5-Year Follow-Up With Clinical and Radiologic Outcomes

Study Design: A retrospective study. Objective: To determine the clinical and radiologic outcomes of the long-term results of instrumented minimally invasive spinal-transforaminal lumbar interbody fusion (MIS-TLIF) in unstable, single-level, low-grade, isthmic spondylolisthesis (IS) or degenerative spondylosis (DS) including degenerative spondylolisthesis, foraminal stenosis with central stenosis, degenerative disk disease, and recurrent disk herniation. Summary of Background Data: MIS-TLIF is a common surgical procedure to treat lumbar spondylolisthesis. However, there are no studies that have documented the long-term results of MIS-TLIF. Methods: Forty-four patients who had undergone instrumented MIS-TLIF between July 2003 and January 2005 were retrospectively reviewed. The visual analog scale, Oswestry Disability Index, patient satisfaction rate, and the patient’s return-to-work status were used to assess clinical and functional outcomes. Radiologic follow-up were carried out in patients to check for adjacent segmental degeneration (ASD). The plain radiographs, computed tomography and magnetic resonance imaging, were used in all patients in last follow-up period. Results: The mean visual analog scale scores for back and leg pain decreased from 5.8 and 7 to 3.5 and 3.7, respectively, in the DS group (n=19) and from 6.8 and 6.9 to 1.8 and 2.0, respectively, in the IS group (n=25) (P
