Retrospective cohort. This study’s primary objective was to compare the clinico-radiological outcomes and incidence of perioperative complications of transforaminal lumbar interbody fusion (TLIF) at lower lumbar levels for elderly and younger patients. The secondary objective was to evaluate the effect of age on clinical outcomes and patient satisfaction in the two groups. The lumbar interbody fusion surgery in elder age has been reported to produce a higher complication rate and suboptimal results. Literature evaluating efficacy and safety of TLIF in elderly population is scanty. The effect of age on clinical outcome and the overall patient satisfaction after TLIF has been understudied. This retrospective study was conducted from 2011 to 2017 with 121 patients, who underwent TLIF and were divided into two cohorts based on age (group A, >65 years and group B, <65 years). Perioperative clinical/radiological parameters, postoperative complications, and satisfactory outcomes were evaluated in both groups. A statistical analysis between two matched groups was performed with logistic regression analysis and Student t-test. The mean age was 73.8±4.5 years in group A and 47.3±12.7 years in group B. There was no statistical difference in surgical time ( In judiciously selected patients with proper preoperative risk assessment and optimized medical co-morbidities, TLIF surgery can have successful results, in terms of clinical outcome and satisfaction, in the elderly. Older age should not be a contraindication for TLIF in patients with degenerative lumbar disease.

Methods:
In total, 225 cases (450 top screws; MIS-TIFL, 120; OPEN-TILF, 105) undergoing single-level lower lumbar fusion were included in the study. Postoperative computed tomography grading system was used to evaluate iatrogenic SFV. Patient and surgical factors such as age, body mass index, top-screw level, side of the top screw, depth of the spine, and superior facet joint angle (SFA) were analyzed in iatrogenic SFV and non-violation groups to determine their influence on iatrogenic SFV. The clinical outcomes in both groups were assessed preoperatively and postoperatively.
Results:
The overall incidence of iatrogenic SFV and high-grade violations was higher in MIS-TLIF (41.25%) than in OPEN-TLIF (30.4%). In both groups, bivariate analysis showed a significantly greater incidence of the iatrogenic SFV in patients aged <60 years and those with obesity, top pedicle screws at L4, right-sided top screws, SFA >35°, and depth of the spine >50 mm.
Conclusions
This study demonstrated that the incidence of iatrogenic SFV is greater in MIS-TLIF than in OPEN-TLIF at a single lower lumbar level. MIS-TLIF is effective for lumbar degenerative disease; however, the incidence of iatrogenic SFV was higher. Patient and surgical factors must be considered to protect the facet joints in both TLIF methods to avoid ASD.
