The influence of gender on postoperative PROMIS physical function outcomes following minimally invasive transforaminal lumbar interbody fusion

PurposeOur aim is to examine the gender performance of Patient-Reported Outcome Measurement Information System Physical Function (PROMIS-PF) scores among patients undergoing minimally invasive transforaminal lumbar fusion (MIS TLIF).MethodsA prospectively collected surgical dataset was retrospectively assessed for eligible patients from March 2015–June 2019. We included patients if they underwent primary MIS TLIF procedures on one or two vertebral levels. We collected baseline demographics, perioperative characteristics, and PROMIS-PF scores for each subject at pre and postoperative timepoints (e.g., 6-weeks, 3-months, 6-months, and 1-year). Chi-squared analyses were utilized to assess categorical variables and a Student’s t-tests analyzed continuous variables. A linear regression was used to analyze PROMIS-PF scores from baseline through all postoperative time points. Finally, we evaluated the PROMIS PF achievement of minimal clinically important difference (MCID) among gender.Results192 patients were included: 77 were females and 115 were males. No significant differences were observed among gender subgroups for PROMIS-PF scores at pre- or postoperative evaluations. Compared to males, females experienced significantly greater postoperative improvement with PROMIS-PF scores at the 3-month assessments, though no significant gender differences were observed during later follow-up evaluations at 6-months or one year. Females were observed to have significant PROMIS-PF score improvement from their preoperative evaluation to each postoperative score. Males were assessed to have statistically significant postoperative (e.g., at 3-months, 6-months, and 1-year) PROMIS-PF score improvement from their preoperative PROMIS-PF scores. There were no significant differences among gender in achieving MCID at any postoperative time interval.ConclusionAmong gender, we observed no statistically significant difference in PROMIS-PF scores during the pre- or postoperative evaluations. Additionally, with no difference in the rate of achieving PROMIS-PF MCID postoperatively, this study established that both genders should experience similar functional outcomes following MIS TLIF.     

Transforaminal lumbar interbody fusion: a safe technique with satisfactory three to five year results

The unilateral transforaminal approach for lumbar interbody fusion as an alternative to the anterior (ALIF) and traditional posterior lumbar interbody fusion (PLIF) combined with pedicle screw instrumentation is gaining in popularity. At present, a prospective study using a standardized tool for outcome measurement after the transforaminal lumber interbody fusion (TLIF) with a follow-up of at least 3 years is not available in the current literature, although there have been reports on specific complications and cost efficiency. Therefore, a study of TLIF was undertaken. Fifty-two consecutive patients with a minimum follow-up of 3 years were included, with the mean follow-up being 46 months (36–64). The indications were 22 isthmic spondylolistheses and 30 degenerative disorders of the lumbar spine. Thirty-nine cases were one-level, 11 cases were two-level, and two cases were three-level fusions. The pain and disability status was prospectively evaluated by the Oswestry disability index (ODI) and a visual analog scale (VAS). The status of bony fusion was evaluated by an independent radiologist using anterior–posterior and lateral radiographs. The operation time averaged 173 min for one-level and 238 min for multiple-level fusions. Average blood loss was 485 ml for one-level and 560 ml for multiple-level fusions. There were four serious complications registered: a deep infection, a persistent radiculopathy, a symptomatic contralateral disc herniation and a pseudarthrosis with loosening of the implants. Overall, the pain relief in the VAS and the reduction of the ODI was significant (P<0.05) at follow-up. The fusion rate was 89%. At the latest follow-up, significant differences of the ODI were neither found between isthmic spondylolistheses and degenerative diseases, nor between one- and multiple-level fusions. In conclusion, the TLIF technique has comparable results to other interbody fusions, such as the PLIF and ALIF techniques. The potential advantages of the TLIF technique include avoidance of the anterior approach and reduction of the approach related posterior trauma to the spinal canal.
