Abstract

Objective: To compare the incidence of the complications of minimally invasive transforaminal lumbar interbody fusion ( MIS-TLIF ) with the posterior lumbar interbody fusion ( PLIF ) in same period, and to investigate its reasons and prevention.

Methods: A retrospective analysis was performed on the 215 patients who underwent MIS-TLIF and PLIF in our hospital from January 2008 to July 2011. Group MIS-TLIF of 105 patients underwent MIS-TLIF. Group PLIF of 110 patients underwent PLIF. The operative time, intra-operative blood loss, the postoperative ambulation time and the operative complications were recorded and compared between two groups.

Result: Mean follow-up duration was 16 months.In group MIS-TLIF, operative complications included dura tearing in 3 cases, neurological injury in 1 case, infection in 1 case and cage subsidence in 2 cases. In group PLIF, operative complications included dura tearing in 6 cases, neurological injury in 7 cases, infection in 3 cases, infection in 1 case cage subsidence in 2 cases and screw loosen in 1 case. There was significant difference in neurological injury and total complication rate between the two groups, P< 0.05.

Conclusion: MIS- TLIF in the treatment of lumbar degenerative disease is safe and effective, and the incidence of the complications of MIS-TLIF is lower than of PLIF.
