A comparative evaluation of operative costs between single level transforaminal interbody fusion (TLIF) and standalone lateral transpsoas interbody fusion (LIF) has not yet been done.


We analyzed the costs, operative parameters, and early outcomes of single level standalone LIF versus single level TLIF.


Ten patients who underwent single level TLIF and ten patients who underwent single-level standalone LIF were included in the analysis. Total, variable, and fixed costs from perioperative data were available from a single institution. In addition, patient demographics, length of hospital stay, and 30 day outcomes and readmission rates were reviewed.


Total cost, variable cost, and fixed costs were significantly lower in the LIF group while there was no difference in outcomes.


Single level standalone LIF may prove to be more cost-effective and provide cost savings with analogous 30 day outcomes as compared single level TLIF procedures.
