Spine Surgery Comparison: Open TLIF Versus Minimal Access TLIF


Fusion rates for open and minimal transforminal lumbar interbody fusion are relatively high and in similar rages, though mTLIF has a trend toward lower complication rates, according to a study published in Spine.

A Medline search identified studies reporting fusion rates on open TLIF and mTLIF with instrumentation. The database included patients from several demographics and showed the fusion and complication rates for each group.

From the 23 identified articles, the TLIF was performed with pedicle fixation and the fusion was evaluated using radiograph or CT scan. The studies included 1, 028 patients and showed the usage of recombinant bone morphologic protein was higher among the mTLIF group.

Mean fusion rates for open TLIF was 90 percent, whereas the mean fusion rate from the mTLIF was 94.8 percent. Complication rate was 12.6 percent for open TLIF and 7.5 percent for mTLIF.
