Patients who underwent minimally invasive transforaminal interbody lumbar fusion to treat debilitating back pain had improved pain and disability scores at short- and long-term follow-up, according to results of this study.
“The [minimally invasive transforaminal lumbar interbody fusion] MITLIF approach seems to provide both short- and long-term statistically significant outcome improvements in patients experiencing debilitating low back pain,” Mick J. Perez-Cruet, MD, MS, and colleagues wrote in the study. “In addition, long-term benefits observed in this study include a reduced rate of adjacent segment disease requiring reoperation while providing high rates of fusion and a low rate of complications.”
Perex-Cruet and colleagues analyzed long-term prospective outcomes for patients who underwent MITLIF. The researchers assessed VAS scores, SF-36 mental component scores and Oswestry Disability Index (ODI) scores preoperatively as well as postoperatively at 2 weeks, 3 months, 6 months, 12 months, 24 months, and then every year up to the 7-year follow-up, according to the abstract.
At mean 47-month follow-up, the mean VAS scores significantly decreased preoperatively to postoperatively from 7 points to 3.5 points. During the same follow-up, ODI scores decreased from 43.1 points to 28.2 points, according to the abstract. SF-36 mental component scores increased at 47-month follow-up from 30.6 points to 39.6 points. — by Jeff Craven
