Complications and clinical outcomes of minimally invasive transforaminal lumbar interbody fusion for the treatment of one- or two-level degenerative disc diseases of the lumbar spine in patients older than 65 years.

Abstract

The clinical and radiological outcomes of MIS-TLIF in the treatment of one- or two-level degenerative disc diseases of lumbar spine in the elderly patients were satisfactory. Though there are more pre-operative comorbidities, with proper patient selection, the elderly patients are not at increased risk of perioperative complications compared to younger patients. Screw malposition and dura tear, which are the most frequent complications, were more related to the surgical technique and should be avoided.
