A new minimally invasive direct lateral interbody fusion (MIS-DLIF) procedure to reduce back pain provides faster and more effective results, says a new study.
The pilot study included nine participants and measured patient-reported pain, surgery time, duration of hospital stay and complications. The new MIS-DLIF is an advancement of the previously developed DLIF/XLIF procedure, which is completed more quickly and has the highest safety record.
Before surgery, patients reported an average of 9.3 out of 10 on sliding pain scale. At the first post-surgical follow-up, patients reported their pain was substantially reduced to 4.8 out of 10. Additional highlights of the study included: average surgery times were 44 minutes and 85 minutes for one and two segment procedures, respectively; and the average hospital stay was 0.3 days and 1.7 days for one and two segment procedures, with 4 of the 9 patients being discharged 2 to 4 hours after surgery.
These results indicate that MIS-DLIF may soon be routinely performed as an outpatient procedure. Also, these results are favorable when compared to those of traditional surgical methods, where procedural durations are between 2 and 4 hours and blood loss is typically 7 to 10 times higher.
MIS-DLIF reduced the risk of complications in the study and showed reduced blood loss by eliminating the need for open surgery via the employment of real time biplanar fluoroscopy X-ray imaging.
The procedure may be helpful for people with back pain due to degenerative disc disease, spondylolisthesis or severe disc herniation.
