Abstract
Analysis of magnetic resonance image (MRI) quality after open (Op)-transforaminal interbody fusion (TLIF) and minimally invasive (MI)-TLIF with the implantation of structurally different systems has not previously been performed. The objective of this study was to conduct a comparative analysis of the postoperative MRI following MI and Op one-segment TLIF. Material and Methods: The nonrandomized retrospective single-center study included 80 patients (46 men and 24 women) aged 48 + 14.2 years. In group I (n = 20) Op-TLIF with open transpedicular screw fixation (TSF) was performed, in II group (n = 60), the MI-TLIF technique was used: IIa (n = 20)—rigid interspinous stabilizer; IIb (n = 20)—unilateral TSF and contralateral facet fixation; IIc (n = 20)—bilateral TSF. Results: Comparison of the quality of postoperative imaging in IIa and IIb subgroups showed fewer MRI artifacts and a significantly greater MR deterioration after Op and MI TSF. Comparison of the multifidus muscle area showed less atrophy after MI-TLIF and significantly greater atrophy after Op-TLIF. Conclusion: MI-TLIF and Op-TLIF with TSF have comparable postoperative MR artifacts at the operative level, with a greater degree of muscle atrophy using the Op-TLIF. Rigid interspinous implant and unilateral TSF with contralateral facet fixation have less artifacts and changes in the multifidus muscle area.
Highlights
Transforaminal interbody fusion (TLIF) and open (Op) dorsal rigid stabilization are the most common methods of surgical treatment for most degenerative diseases of the lumbar spine [1,2]
This study has shown that using various types of implants to stabilize the posterior support complex during single-level minimally invasive (MI)-transforaminal interbody fusion (TLIF) does not impair the quality of postoperative visualization of the adjacent segments
Postoperative magnetic resonance image (MRI) for assessing neural structures, paravertebral tissues, and segments adjacent to the operation depend on both the surgical intervention and type of structure used to stabilize the posterior support complex
Summary
Transforaminal interbody fusion (TLIF) and open (Op) dorsal rigid stabilization are the most common methods of surgical treatment for most degenerative diseases of the lumbar spine [1,2]. Minimally invasive (MI) decompression and stabilization techniques are actively used in modern spinal surgery and associated with better clinical outcomes due to less paravertebral tissue damage, minimum postoperative pain syndrome, and shorter recovery [3,4]. Adverse consequences of such interventions can be cage migration, instability of the structure, degeneration of the adjacent level, and postoperative muscle atrophy; for these reasons, complete visualization of the operated and adjacent levels is a mandatory requirement for medical implants [5,6].
