Comparison of three different posterior fixation techniques in transforaminal lumbar interbody fusion for two-level lumbar degenerative diseases: At a mean follow up time of 46 months
文摘

We are the first to investigate three fixation techniques in two-level lumbar cases.

UPS/UPSFS could achieve satisfactory mid-term clinical outcome comparable to BPS.

UPS instrumented TLIF should be prudently performed for two-level cases.

Cannulated screws should be replaced by solid screws in UPSFS instrumented TLIF.
