Patients underwent the procedure at an outpatient spine clinic and were followed for an average of 47 months. The researchers found at 47 months after surgery:
• Visual analogue scale scores decreased postoperatively from 7.0 to 3.5.
• Oswestry Disability Index scores dropped postoperatively from 43.1 to 28.2.
• Short-Form 36 mental component scores increased from 43.8 to 49.7.
• Short-Form 36 physical component scores increased from 30.6 to 39.6.
“MITLIF resulted in a high rate of spinal fusion and very low rate of interbody fusion failure and/or adjacent segment disease requiring reoperation while reducing postoperative complications,” the authors concluded.
