This retrospective review compared short-term outcomes of modified Open TLIF with tubular MIN-TLIF, showing favorable results in terms of avoidance of blood transfusions, shorter hospital stays, and less opioid usage while maintaining satisfactory patient-reported outcomes.
Study Design: This study is a retrospective review of patients' charts and data from longitudinally collected clinical outcomes and opioid use. Objective: In the current study, we aim to compare short-term outcomes data for 139 Open transforaminal interbody fusion (TLIF) patients to recently published data for tubular and endoscopic MIS-TLIF. Background Context: In response to the downsides associated with Open TLIF, such as large incision, blood loss, delayed ambulation, prolonged hospitalization, and opioid-reliance, spine surgeons developed tubular retractor based minimally-invasive TLIF. However, the traditional Open TLIF retains its significance in terms of providing successful fusion and improved patient-reported outcomes (PROs). Methods: We adapted several techniques with an aim to improve short-term outcomes for our Open TLIF patients that combined extensive perioperative counselling, an emphasis on early mobilization, avoidance of overuse of opioid analgesics, early discharge with home care arrangements, use of a posthospitalization drainage tube with intraoperative surgical modifications using small incisions (4-5 cm), a narrow 20 mm retractor, minimal muscle injury, and use of a cell saver to minimize net blood loss. The demographics and perioperative results were compared with data from recent MIS-TLIF studies using Student t test for continuous and chi(2)/exact test for categorical variables. Results: Among the total 139 patients, 115 underwent a single-level procedure, 90% of whom were discharged on the first postoperative day (length of stay=1.13 +/- 0.47 d) with an average net estimated blood loss of 176.17 +/- 87.88 mL. There were 24 two-level procedures with an average length of stay of 1.57 +/- 0.84 days, average net estimated blood loss was 216.96 +/- 85.70 mL. The patients had statistically significant improvements in PROs at 3 and 12 months. Conclusions: The results of this study identify that patients who underwent modified Open TLIF demonstrated favorable short-term outcomes, as compared with the tubular MIS-TLIF, by virtue of avoidance of blood transfusions, shorter hospital stays, and significantly less opioid usage while experiencing satisfactory PROs.
