ABSTRACT

OBJECTIVE: Sacroiliac joint (SIJ) dysfunction is a significant cause of back pain. Despite recent advances in minimally invasive (MIS) SIJ fusion, the fusion rate remains controversial. This study sought to demonstrate that a navigated decortication and direct arthrodesis technique in MIS SIJ fusion would result in satisfactory fusion rates and patient-reported outcomes (PROs). METHODS: The authors retrospectively reviewed consecutive patients who underwent MIS SIJ fusion from 2018 to 2021. SIJ fusion was performed using cylindrical threaded implants and SIJ decortication employing the O-arm surgical imaging system and StealthStation. The primary outcome was fusion, evaluated using CT at 6, 9, and 12 months postoperatively. Secondary outcomes included revision surgery, time to revision surgery, visual analog scale (VAS) score for back pain, and the Oswestry Disability Index (ODI), measured preoperatively and 6 and 12 months postoperatively. Patient demographics and perioperative data were also collected. PROs over time were analyzed using ANOVA followed by a post hoc analysis. RESULTS: One hundred eighteen patients were included in this study. The mean (± SD) patient age was 58.56 ± 13.12 years, and most patients were female (68.6% vs 31.4% male). There were 19 smokers (16.1%) with an average BMI of 29.92 ± 6.73. One hundred twelve patients (94.9%) underwent successful fusion on CT. The ODI improved significantly from baseline to 6 months (Δ7.73, 95% CI 2.43-13.03, p = 0.002) and from baseline to 12 months (Δ7.54, 95% CI 1.65-13.43, p = 0.008). Similarly, VAS back pain scores improved significantly from baseline to 6 months (Δ2.31, 95% CI 1.07-3.56, p < 0.001) and from baseline to 12 months (Δ1.63, 95% CI 0.25-3.00, p = 0.015). CONCLUSIONS: MIS SIJ fusion with navigated decortication and direct arthrodesis was associated with a high fusion rate and significant improvement in disability and pain scores. Further prospective studies examining this technique are warranted.

ABSTRACT

BACKGROUND AND PURPOSE: While patients with angiogram-negative subarachnoid hemorrhages (ANSAH) have better prognoses than those with aneurysmal SAH, frailty's impact on outcomes in ANSAH is unclear. We previously showed that the modified frailty index (mFI-11) is associated with poor outcomes following ANSAH. Here, we compared the mFI-5, mFI-11, Charlson Comorbidity Index (CCI), and temporalis thickness (TMT) to determine which index was the best predictor of ANSAH outcomes and mortality rates. METHODS: In this retrospective cohort analysis between 2014 and 2018, patients with non-traumatic, angiogram negative SAH (ANSAH) were identified. The admission mFI-5, mFI-11, CCI, and TMT were calculated for each patient. Primary outcomes were mortality rate, discharge location, and prolonged length of stay (PLOS; LOS >85th percentile). Multivariate logistic regression and receiver operating characteristic (ROC) curves were used to evaluate frailty as predictors of primary endpoints. RESULTS: We included 75 patients with a mean age of 55.4 ± 1.5 years. There were 4 patient deaths (5.3%), 53 patients (70.7%) discharged home, and 11 patients (14.7%) with PLOS. On ROC analysis, the mFI-5 had the highest discriminatory value for mortality (AUC = 0.97) while the mFI-11 was most discriminatory for discharge home (AUC = 0.85) and PLOS (AUC = 0.78). On multivariate analysis, the only independent predictor of mortality was the mFI-11 (OR = 0.46; 95%CI: 1.45-14.23; p = 0.009) while the mFI-5 was the best predictor of discharge home (OR = 0.21; 95% CI: 0.08-0.61; p = 0.004). On multivariate analysis, the only independent predictor of PLOS was the Hunt and Hess score (OR = 2.63; 95%CI: 1.38-5.00; p = 0.003). The CCI and TMT were inferior to either mFI for predicting primary endpoints. CONCLUSIONS: Increasing frailty is associated with poorer outcomes and higher mortality following ANSAH. The mFI-5 and mFI-11 were found to be superior predictors of discharge home and mortality rate. While larger prospective study is needed, frailty, as measured by mFI-11 and -5, should be considered when evaluating ANSAH prognosis.

ABSTRACT

BACKGROUND: The effect of frailty on outcomes after angiogram-negative subarachnoid hemorrhages (ANSAH) is currently unknown. We investigated frailty's effects on ANSAH outcomes, including mortality and in-hospital complications. METHODS: Patients from 2014 to 2018 with non-traumatic subarachnoid hemorrhage and cerebral angiograms with an unidentifiable hemorrhage source were retrospectively reviewed. The cohort was divided into non-frail (modified frailty index [mFI] = 0) and frail (mFI ≥1) groups based on pre-hemorrhage characteristics. Primary outcomes were mortality rate and discharge location. Multivariate logistic regression analyses determined predictors of ANSAH severity and primary endpoints. Receiver operating characteristic curves were used to discriminate risks for primary endpoints comparing mFI, Hunt and Hess and Fisher scores, and age. RESULTS: We included 75 patients with a mean age of 55.4 ± 1.5 years, comprising 42 (56%) women, and 41 (54.7%) with perimesencephalic bleeds. A total of 32 of 75 (42.7%) patients were classified as frail. Frail individuals were 6.2 times less likely to be discharged home (odds ratio [OR] = 0.16; 95% confidence interval [CI]: 0.05-0.5; P = 0.001) and all mortalities occurred in frail patients (12.5% [n = 4 of 32]; P = 0.030). The only independent predictor of mortality was higher mFI (OR = 5.4; 95% CI: 1.5-19.1; P = 0.009), and lower mFI best predicted discharge home (OR = 0.39; 95% CI: 0.17-0.88; P = 0.023). Receiver operating characteristic analysis showed that mFI best predicted both mortality (area under the curve = 0.9718; P = 0.002) and discharge home (area under the curve = 0.7998; P < 0.001). CONCLUSIONS: Frail ANSAH patients have poorer outcomes and increased mortality compared with non-frail patients. Although prospective study is needed, this information significantly impacts our understanding of ANSAH outcomes and frailty should be used for prognostication as it was a better predictor than Hunt and Hess or Fisher scores.
