abstract
OBJECTIVES: In a retrospective study, we sought to compare the clinical efficacy and postoperative magnetic resonance imaging (MRI) scans of minimally invasive (MI) and open (O) transforaminal lumbar interbody fusion (TLIF) in the treatment of cauda equina syndrome (CES) caused by lumbar disc herniation. METHODS: In total, 116 patients with CES associated with disc herniation underwent decompression and stabilization surgery from January 2005 to January 2020 in a single-center study, and data were collected and retrospectively analyzed. The patients were divided into the O-TLIF and the MI-TLIF group. The perioperative clinical data and MRI assessment were used to assess the efficacy of the respective surgical methods preoperatively and with a minimum follow-up of 30 months. RESULTS: As expected, the O-TLIF group had statistically significantly longer surgery times and hospital stay, more bleeding, and perioperative surgical complications than the MI-TLIF group. At a minimum follow-up period of 30 months, the MI-TLIF group had significantly better Oswestry Disability Index, visual analog scale, and Short-Form-36, and neurologic CES symptoms than the O-TLIF group. The postoperative MRIs revealed a statistically significant difference in the multifidus muscle area in MI group compared with the O group. CONCLUSIONS: In patients with acute CES caused by disc herniation, MI-TLIF, with decreased disruption of paravertebral tissues and postoperative pain syndrome, results in earlier mobilization and rehabilitation with better long-term clinical outcomes compared with O-TLIF.
