Minimally Invasive Transforaminal Lumbar Interbody Fusion with Unilateral Pedicle Screw Fixation : Comparison between Primary and Revision Surgery

الملخص EN

Minimally invasive surgery with a transforaminal lumbar interbody fusion (MIS TLIF) is an important minimally invasive fusion technique for the lumbar spine.

Lumbar spine reoperation is challenging and is thought to have greater complication risks.

The purpose of this study was to compare MIS TLIF with unilateral screw fixation perioperative results between primary and revision surgeries.

This was a prospective study that included 46 patients who underwent MIS TLIF with unilateral pedicle screw.

The patients were divided into two groups, primary and revision MIS TLIF, to compare perioperative results and complications.

The two groups were similar in age, sex, and level of operation, and were not significantly different in the length of follow-up or clinical results.

Although dural tears were more common with the revision group (primary 1; revision 4), operation time, blood loss, total perioperative complication, and fusion rates were not significantly different between the two groups.

Both groups showed substantial improvements in VAS and ODI scores one year after surgical treatment.

Revision MIS TLIF performed by an experienced surgeon does not necessarily increase the risk of perioperative complication compared with primary surgery.

MIS TLIF with unilateral pedicle screw fixation is a valuable option for revision lumbar surgery.
