Good outcomes seen in patients who have minimally invasive lumbar fusion for severe low back pain

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
