Background: It is theoretically presumed that TLIF will provide the same advantages as circumferential fusion, but with a higher level of safety than other inter body fusion methods, as it does not involve direct traction on the spine. TLIF technology preserves the interspinal ligament and supraspinal ligament in terms of spinal integrity. Goal and objectives: We aimed to evaluate the clinical outcomes, complications, and advantages of transforaminal lumbar inter body fusion in degenerative lumbar spine diseases. Subjects and methods: The orthopedic department of Menoufia University Hospital conducted a study between November 2018 and December 2020 on 30 patients who were experiencing persistent low back discomfort as a consequence of degenerative lumbar spine disorders.. The patients underwent transforaminal lumbar interbody fusion with a PEEK Banana cage and pedicle screw fixation, with a minimum follow-up of 9 months. Result: All of the patients under investigation had a severe Oswestry disability index (ODI) at the preoperative stage (100%). On the initial postoperative day, they are all incapable of being evaluated at a 100% level. The majority of the patients who were examined had experienced a moderate ODI, in addition. The Oswestry disability index (ODI) demonstrated a significant linear improvement in the patients under investigation, with the most considerable improvement occurring within the first three months following the operation. In summary, TLIF generates favorable clinical and radiological outcomes in the management of lumbar instability after a one-year follow-up period. Dural rupture and operational complications are substantially diminished by the TLIF technique. TLIF has the potential to reduce the duration of the operation and the volume of blood loss.
