Standard versus Minimally Invasive Transforaminal Lumbar Interbody Fusion: A Prospective Randomized Study

Table 3

Comparison of clinical and radiological outcomes [S TLIF = standard transforaminal lumbar interbody fusion; MI TLIF = minimally invasive transforaminal lumbar interbody fusion; EBL = estimated blood loss; POD discharge = postoperative day of discharge].
