ABSTRACT

This manuscript examines the challenges and initiatives within organizations associated with spine surgery to enhance diversity, equity, and inclusion (DEI), focusing on the systemic barriers that hinder the representation of women and underrepresented in medicine (URiM) minorities. Highlighting the contributions of pioneering individuals who overcame racial and gender discrimination to forge paths in these fields, it stresses the importance of professional societies and foundations in promoting DEI. Despite advancements, legal challenges and recent legislation in various states threaten to undermine DEI efforts, presenting a critical moment for organizations to reassess and reinforce their strategies. By detailing the roles of specific professional societies, foundations, and initiatives like the American Society of Black Neurosurgeons and Nth Dimensions, the manuscript underscores the necessity of targeted actions to ensure the progress toward a more inclusive and equitable spine surgery community.

ABSTRACT

Background and objectives: This study investigates geographic disparities in aneurysmal subarachnoid hemorrhage (aSAH) care for Black patients and aims to explore the association with segregation in treatment facilities. Understanding these dynamics can guide efforts to improve healthcare outcomes for marginalized populations. Methods: This cohort study evaluated regional differences in segregation for Black patients with aSAH and the association with geographic variations in disparities from 2016 to 2020. The National Inpatient Sample (NIS) database was queried for admission data on aSAH. Black patients were compared to White patients. Segregation in treatment facilities was calculated using the dissimilarity (D) index. Using multivariable logistic regression models, the regional disparities in aSAH treatment, functional outcomes, mortality, and end-of-life care between Black and White patients and the association of geographical segregation in treatment facilities was assessed. Results: 142,285 Black and White patients were diagnosed with aSAH from 2016 to 2020. The Pacific division (D index = 0.55) had the greatest degree of segregation in treatment facilities, while the South Atlantic (D index = 0.39) had the lowest. Compared to lower segregation, regions with higher levels of segregation (global F test p < 0.001) were associated a lower likelihood of mortality (OR 0.91, 95% CI 0.82-1.00, p = 0.044 vs. OR 0.75, 95% CI 0.68-0.83, p < 0. 001) (p = 0.049), greater likelihood of tracheostomy tube placement (OR 1.45, 95% CI 1.22-1.73, p < 0.001 vs. OR 1.87, 95% CI 1.59-2.21, p < 0.001) (p < 0. 001), and lower likelihood of receiving palliative care (OR 0.88, 95% CI 0.76-0.93, p < 0.001 vs. OR 0.67, 95% CI 0.59-0.77, p < 0.001) (p = 0.029). Conclusion: This study demonstrates regional differences in disparities for Black patients with aSAH, particularly in end-of-life care, with varying levels of segregation in regional treatment facilities playing an associated role. The findings underscore the need for targeted interventions and policy changes to address systemic healthcare inequities, reduce segregation, and ensure equitable access to high-quality care for all patients.

ABSTRACT

Background: This study examines the lasting impact of historical redlining on contemporary neurosurgical care access, highlighting the need for equitable healthcare in historically marginalized communities. Objective: To investigate how redlining affects neurosurgeon distribution and reimbursement in U.S. neighborhoods, analyzing implications for healthcare access. Methods: An observational study was conducted using data from the Center for Medicare and Medicaid Services (CMS) National File, Home Owner's Loan Corporation (HOLC) neighborhood grades, and demographic data to evaluate neurosurgical representation across 91 U.S. cities, categorized by HOLC Grades (A, B, C, D) and gentrification status. Results: Of the 257 neighborhoods, Grade A, B, C, and D neighborhoods comprised 5.40%, 18.80%, 45.8%, and 30.0% of the sample, respectively. Grade A, B, and C neighborhoods had more White and Asian residents and less Black residents compared to Grade D neighborhoods (p < 0.001). HOLC Grade A (OR = 4.37, 95%CI: 2.08, 9.16, p < 0.001), B (OR = 1.99, 95%CI: 1.18, 3.38, p = 0.011), and C (OR = 2.37, 95%CI: 1.57, 3.59, p < 0.001) neighborhoods were associated with a higher representation of neurosurgeons compared to Grade D neighborhoods. Reimbursement disparities were also apparent: neurosurgeons practicing in HOLC Grade D neighborhoods received significantly lower reimbursements than those in Grade A neighborhoods ($109,163.77 vs. $142,999.88, p < 0.001), Grade B neighborhoods ($109,163.77 vs. $131,459.02, p < 0.001), and Grade C neighborhoods ($109,163.77 vs. $129,070.733, p < 0.001). Conclusion: Historical redlining continues to shape access to highly specialized healthcare such as neurosurgery. Efforts to address these disparities must consider historical context and strive to achieve more equitable access to specialized care.

ABSTRACT

Stroke is a major health concern in the USA, disproportionately affecting socioeconomically disadvantaged groups. This study investigates the link between persistent poverty and stroke mortality rates in residents aged 65 and above, positing that sustained economic challenges at the county level correlate with an increase in stroke-related deaths. Persistent poverty refers to a long-term state where a significant portion of a population lives below the poverty threshold for an extended period, typically measured over several decades. It captures the chronic nature of economic hardship faced by a community across multiple generations. Utilizing data from the CDC Wonder database and the American Community Survey, we conducted a comprehensive analysis across US counties, differentiating them by persistent poverty status. Our results indicate a statistically significant link between persistent poverty and increased mortality from ischemic and hemorrhagic strokes; counties afflicted by long-standing poverty were associated with an additional 33.49 ischemic and 8.16 hemorrhagic stroke deaths per 100,000 residents annually compared to their wealthier counterparts. These disparities persisted when controlling for known stroke risk factors and other socioeconomic variables. These results highlight the need for targeted public health strategies and interventions to address the disparities in stroke mortality rates and the broader implications for healthcare equity. The study underscores the vital role of socioeconomic context in health outcomes and the urgency of addressing long-term poverty as a key determinant of public health.

ABSTRACT

BACKGROUND: There is a controversy on the effectiveness of post-operating splinting in patients with carpal tunnel release (CTR) surgery. This study aimed to systematically evaluate various outcomes regarding the effectiveness of post-operating splinting in CTR surgery. METHODS: Multiple databases, including PubMed, EMBASE, CINAHL, Web of Science, and Cochrane, were searched for terms related to carpal tunnel syndrome. A total of eight studies involving 596 patients were included in this meta-analysis. The quality of studies was evaluated, and their risk of bias was calculated using the methodological index for non-randomized studies (MINORS) and Cochrane's collaboration tool for assessing the risk of bias in randomized controlled trials. Data including the visual analogue scale (VAS), pinch strength, grip strength, two-point discrimination, symptom severity score (SSS), and functional status scale (FSS) were extracted. RESULTS: Our analysis showed no significant differences between the splinted and non-splinted groups based on the VAS, SSS, FSS, grip strength, pinch strength, and two-point discrimination. The calculated values of the standardized mean difference (SMD) or the weighted mean difference (WMD) and a 95% confidence interval (CI) for different variables were as follows: VAS [SMD = 0.004, 95% CI (-0.214, 0.222)], pinch strength [WMD = 1.061, 95% CI (-0.559, 2.681)], grip strength [SMD = 0.178, 95% CI (-0.014, 0.369)], SSS [WMD = 0.026, 95% CI (- 0.191, 0.242)], FSS [SMD = 0.089, 95% CI (-0.092, 0.269)], and the two-point discrimination [SMD = 0.557, 95% CI (-0.140, 1.253)]. CONCLUSIONS: Our findings revealed no statistically significant differences between the splinted and non-splinted groups in terms of the VAS, SSS, FSS, grip strength, pinch strength, and two-point discrimination. These results indicate that there is no substantial evidence supporting a significant advantage of post-operative splinting after CTR.

ABSTRACT

BACKGROUND: This study explores racial and socioeconomic disparities in aneurysmal subarachnoid hemorrhage (aSAH) care, highlighting the impact on treatment and outcomes. The study aims to shed light on inequities and inform strategies for reducing disparities in healthcare delivery. METHODS: In this cohort study the National Inpatient Sample database was queried for patient admissions with ruptured aSAH from 2016 to 2020. Multivariable analyses were performed estimating the impact of socioeconomic status and race on rates of acute treatment, functional outcomes, mortality, receipt of life-sustaining interventions (mechanical ventilation, tracheostomy, gastrostomy, and blood transfusions), and end-of-life care (palliative care and do not resuscitate). RESULTS: A total of 181 530 patients were included. Minority patients were more likely to undergo treatment (OR 1.15, 95% CI 1.09 to 1.22, P<0.001) and were less likely to die (OR 0.89, 95% CI 0.84 to 0.95, P<0.001) than White patients. However, they were also more likely to have a tracheostomy (OR 1.47, 95% CI 1.33 to 1.62, P<0.001) and gastrostomy tube placement (OR 1.43, 95%CI 1.32 to 1.54, P<0.001), while receiving less palliative care (OR 0.75, 95% CI 0.70 to 0.80, P<0.001). This trend persisted when comparing minority patients from wealthier backgrounds with White patients from poorer backgrounds for treatment (OR 1.10, 95% CI 1.00 to 1.21, P=0.046), mortality (OR 0.82, 95% CI 0.74 to 0.89, P<0.001), tracheostomy tube (OR 1.27, 95% CI 1.07 to 1.48, P<0.001), gastrostomy tube (OR 1.34, 95% CI 1.18 to 1.52, P<0.001), and palliative care (OR 0.76, 95% CI 0.69 to 0.84, P<0.001). CONCLUSIONS: Compared with White patients, minority patients with aSAH are more likely to undergo acute treatment and have lower mortality, yet receive more life-sustaining interventions and less palliation, even in higher socioeconomic classes. Addressing these disparities is imperative to ensure equitable access to optimal care and improve outcomes for all patients regardless of race or class.

ABSTRACT

OBJECTIVE: Racial disparities are ubiquitous across medicine in the US. This study aims to assess the evidence of racial disparities within neurosurgery and across its subspecialties, with a specific goal of quantifying the distribution of articles devoted to either identifying, understanding, or reducing disparities. METHODS: The authors searched the MEDLINE, EMBASE, and Scopus databases by using keywords to represent the concepts of neurosurgery, patients, racial disparities, and specific study types. Two independent reviewers screened the article titles and abstracts for relevance. A third reviewer resolved conflicts. Data were then extracted from the included articles and each article was categorized into one of three phases: identifying, understanding, or reducing disparities. This review was conducted in accordance with the PRISMA Extension for Scoping Reviews (PRISMA-ScR) guidelines. RESULTS: Three hundred seventy-one studies published between 1985 and 2023 were included. The distribution of racial disparities literature was not equally spread among specialties, with spine representing approximately 48.3% of the literature, followed by tumor (22.1%) and general neurosurgery (12.9%). Most studies were dedicated to identifying racial disparities (83.6%). The proportion of literature devoted to understanding and reducing disparities was much lower (15.1% and 1.3%, respectively). Black patients were the most negatively impacted racial/ethnic group in the review (63.3%). The Hispanic or Latino ethnic group was the second most negatively impacted (25.1%). The following categories-other outcomes (28.0%), the offering of treatment (21.6%), complications (18.6%), and survival (16.7%)-represented the most frequently measured outcomes. CONCLUSIONS: Although strides have been taken to identify racial disparities within neurosurgery, fewer studies have focused on understanding and reducing these disparities. The tremendous rise of literature within this domain but the relative paucity of solutions necessitates the study of targeted interventions to provide equitable care for all patients undergoing neurosurgical treatment.

ABSTRACT

OBJECTIVE: Despite the increasing number of women and racial/ethnic minorities sustaining traumatic brain injuries (TBIs), they are underrepresented in TBI clinical trials. This study aimed to evaluate gender and racial diversity in enrolled cohorts of TBI clinical trials to identify trends and predictors of increased disparity over time. METHODS: The authors reviewed TBI clinical trials with reported results registered on the website ClinicalTrials.gov between 2008 and 2022. The studies were assessed for the proportion of women and racial/ethnic minorities enrolled as well as their reporting of race- and gender-specific characteristics such as gender ratio (GR) and Racial Diversity Index (RDI). Further study parameters, including year and duration, phase, trial design, type of funding, and trial completion, were also included. RESULTS: One hundred thirty-five clinical trials met inclusion criteria, of which 65 and 134 reported race and gender, respectively. Twenty-five trials were found to have existing racial disparity (RDI < 1). Comparatively, industry-funded trials had a 26% greater likelihood of racial disparities (p = 0.026), whereas federally funded trials were 30% less likely to demonstrate racial disparities (p = 0.031). Sixty-six trials had gender disparities (GR < 0.4) present, with federally funded trials showing 37.1% greater rates of gender disparity (p < 0.001, adjusted OR 5.47, 95% CI 2.26-14.25). The impact of funding source on race and gender remained significant despite adjusting for other covariates in the multivariate analyses. Racial disparity was negatively correlated with trial completion rate (p < 0.001). Disparities were not found to improve over the 14-year time span. CONCLUSIONS: Racial and gender disparities in TBI clinical trial enrollment persist, and the lack of diversity may lead to biased evidence-based medicine. Efforts should be made to increase the representation of women and racial/ethnic minorities in TBI clinical trials to ensure equitable access to effective treatments for all populations.

ABSTRACT

OBJECTIVE: Over the past 20 years, female representation in neurosurgical residency programs has steadily increased. Still, the number of Black women and Black neurosurgical residents overall has remained stagnant. The authors aimed to understand the factors that led to this stagnation and how online public domain representation informs current and upcoming resident recruitment and decision-making. METHODS: The authors performed a retrospective study using the following public domain sources: Doximity, neurosurgical residency program websites, and LinkedIn. The authors collected data from all neurosurgery residents who matriculated into a US neurosurgical residency program from 2015 to 2022. Variables, including name, race, gender, year of matriculation, medical school, and undergraduate institution, were recorded. RESULTS: The authors analyzed resident data from 110/113 (97.3%) US neurological surgery residency programs. Of these programs, 106 (96.4%) matriculated and retained ≥ 1 female resident over the study period. There were 408 (22.6%) female neurosurgical residents, with 37 (33.6%) programs accounting for 57.8% of all female neurosurgical residents. For those states with a female resident, the lowest percentage of female residents by state was in Iowa (6.25%) and the highest was in New Hampshire (50%). Of all programs, 60 (54.5%) matriculated and retained ≥ 1 Black resident over the study period. There were 88 (4.9%) Black neurosurgical residents, with 19 (17.3%) programs accounting for 55.7% of all Black neurosurgical residents. For those states with a Black resident, the lowest percentage of Black residents by state was in Maryland (2.0%) and the highest was in Arkansas (23.1%). CONCLUSIONS: Recruiting and retaining female and Black residents has increasingly become a focus of neurosurgical programs across the country. The authors' data show that female and Black residents overwhelmingly choose to apply to and matriculate into programs that demonstrate a commitment to diversity via their online presence. Programs wishing to recruit more diverse residents should make efforts to relay their dedication to diversity, inclusion, and performance through their online presence.

ABSTRACT

OBJECTIVE: To examine the progress made in recent decades by assessing the employment rates of Black and non-Hispanic White (NHW) patients after traumatic brain injury (TBI), controlling for pre-TBI employment status and education status. DESIGN: Retrospective analysis in a cohort of patients treated in Southeast Michigan at major trauma centers in more recent years (February 2010 to December 2019). SETTING: Southeastern Michigan Traumatic Brain Injury Model System (TBIMS): 1 of 16 TBIMSs across the United States. PARTICIPANTS: NHW (n=81) and Black (n=188) patients with moderate/severe TBI (N=269). INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Employment status, which is separated into 2 categories: student plus competitive employment and noncompetitive employment. RESULTS: In 269 patients, NHW patients had more severe initial TBI, measured by percentage brain computed tomography with compression causing >5-mm midline shift (P<.001). Controlling for pre-TBI employment status, we found NHW participants who were students or had competitive employment prior to TBI had higher rates of competitive employment at 2-year (P=.03) follow-up. Controlling for pre-TBI education status, we found no difference in competitive and noncompetitive employment rates between NHW and Black participants at all follow-up years. CONCLUSIONS: Black patients who were students or had competitive employment before TBI experience worse employment outcomes than their NHW counterparts after TBI at 2 years post TBI. Further research is needed to understand better the factors driving these disparities and how social determinants of health affect these racial differences after TBI.

ABSTRACT

BACKGROUND: Cervical spondylotic myelopathy (CSM) is a common degenerative disease that arises from spinal cord compression and injury. Laminectomy with posterior spinal fusion (LPSF) is one of the most common approaches used to treat patients with CSM. The present study aimed to evaluate predictors of poor clinical outcome in patients with CSM undergoing LPSF. METHODS: We retrospectively evaluated 157 patients with CSM who underwent LPSF at our center between April 2014 and June 2019. The neurological outcome was assessed using the modified Japanese Orthopaedic Association (mJOA) scale before the surgery and at the last follow-up visit. Based on the clinical outcomes, all patients were divided into two groups [the good group (recovery rates ≥ 75%) and the poor group (recovery rates < 75%)]. The following suggested variables as potential predictors for the poor clinical outcome were compared between the two groups:age, gender, body mass index (BMI), smoking, diabetes, number of laminectomy levels, presence of signal changes in Magnetic Resonance Imaging (MRI), duration of symptoms, preoperative JOA scale, preoperative Pavlov ratio, preoperative cervical curvature, and preoperative cervical range of motion (ROM). RESULTS: There were 86 males (54.8%) and 71 females (45.2%) with the mean follow-up time of 24.96 ± 1.67 months. Overall, 114 patients (72.6%) had a good clinical outcome. However, 43 subjects (27.4%) failed to achieve a good outcome. According to the binary logistic regression analysis, age (odds ratio [OR], 2.14; 95% confidence interval [95% CI], 1.87-2.63; P = 0.014) and preoperative JOA scale (OR, 3.73; 95% CI 2.96-4.87; p < 0.001) were independent predictors of poor clinical outcome. CONCLUSIONS: The results of the present study showed that age and preoperative JOA scale were predictors of poor clinical outcome in patients with CSM undergoing LPSF. These findings will be of great value in preoperative counseling and management of postoperative expectations.

ABSTRACT

BACKGROUND: Atypical meningiomas (AM) comprise a heterogeneous conglomeration of meningiomas with higher local recurrence rates than their benign counterparts. Although adjuvant therapy following subtotal resection is the standard, the use of adjuvant therapy following gross total resection (GTR) remains controversial. This study seeks to add to the literature by identifying radiopathologic predictors of recurrence in patients with a GTR AM and better identify those patients who may benefit from adjuvant therapy. METHODS: A total of 103 consecutive patients who received gross total resection for AM at our center between Apr 2010 and Apr 2019 were evaluated retrospectively. Recurrence was defined as new enhancing masses on MRI without requiring biopsy confirmation. Cumulative incidence plots were used to estimate survival, and the log-rank test was used to assess differences between groups. Cox proportional hazards models were used to evaluate the effect of radiopathologic variables on the hazard of recurrence. RESULTS: Of the 103 patients included in this study, 68 (66.0%) were female, and the mean age was 51.1 ± 11.4. The median overall survival for patients following surgery was 71 months while the median progression-free survival was 64 months. Recurrence occurred in 36 (35.0%) patients. Factors correlated with AM recurrence following GTR included peritumoral edema (p = 0.005), necrosis (p < 0.001), mitotic rate greater than 7/10 high-power field (HPF) (p < 0.001), and Ki67 > 15% (p < 0.001). However, following Cox proportional hazards regression analysis, only mitotic rate greater than 7/10HPF (p = 0.018) and Ki67 > 15% (p = 0.035) were significantly associated with AM recurrence. CONCLUSIONS: Our results showed high mitotic index (greater than 7/10 HPF) and Ki67 greater than 15% as independent predictors of recurrence in patients with a GTR AM. These findings could help stratify patients who may benefit from adjuvant therapy.Abbreviations: AM: Atypical meningiomas; GTR: gross total resection; HPF: high power field; STR: subtotal resection; RFS: recurrence-free survival.

ABSTRACT

The 2019 coronavirus pandemic (COVID-19) has affected all of society at different levels. Similarly, COVID-19 has significantly impacted every medical field, including neurosurgery. By exposing scarcities in the healthcare industry and requiring the reallocation of available resources towards the priority setting and away from elective surgeries and outpatient visits, the pandemic posed new, unprecedented challenges to the medical community. Despite the redistribution of resources towards COVID-19 patients and away from elective surgeries, urgent and emergent surgeries for life-threatening conditions needed to be continued. The neurosurgical community, like other specialties not directly involved in the care of COVID-19 patients, initially struggled to balance the needs of COVID-19 patients with those of neurosurgical patients, residents, and researchers. Several articles describing the effect of COVID-19 on neurosurgical practice and training have been published throughout the COVID-19 pandemic. This article aims to provide a focused review of the impact COVID-19 has had on neurosurgical practice and training as well as describe neurological manifestations of the disease.

ABSTRACT

BACKGROUND: The neutrophil to lymphocyte ratio (NLR) has been reported to be associated with clinical outcomes of patients with severe traumatic brain injury (TBI). This study aimed to evaluate the correlation between the dynamics of NLR and clinical outcomes of pediatric patients with moderate to severe TBI. METHODS: We retrospectively evaluated the clinical data of a total of 374 pediatric patients with moder-ate to severe TBI who were treated in our department between May 2016 and May 2020. Clinical and laboratory data including the NLR upon admission and the NLR on hospital day four were collected. Poor clinical outcome was defined as Glasgow Outcome Scale (GOS) of 1-3. Multivariable logistic regression analyses were performed to investigate the correlation between the dynamics of NLR and clinical outcome. RESULTS: Three hundred seventy-four pediatric patients (mean age 7.37 ± 3.11, 52.7% male) were evaluated. Based on the ROC curves, a value of 5 was determined as the NLR cut-off value. The corresponding cutoff value for delta NLR was 1. The Glasgow Coma Scale (GCS) (OR, 3.42; 95% CI: 1.88-5.28; P <0.001), the light reflex (OR, 1.79; 95% CI: 1.34- 2.84; P = 0.027), the Rotterdam CT score (OR, 2.71; 95% CI: 1.72-4.13; P = 0.021), and delta NLR (OR, 1.71; 95% CI: 1.13- 2.52; P = 0.034) were identified as independent predictors for unfavorable outcomes in multivariable logistic regression analysis. CONCLUSIONS: The result of the present study suggest that delta NLR could be a predictor of poor clinical outcome of pediatrics with moderate to severe TBI. This cost-effective and easily available biomarker could be used to predict clinical outcomes in these patients.

ABSTRACT

BACKGROUND: Traumatic brain injury (TBI) is one of the main causes of death and disability among the elderly patient population. This study aimed to assess the predictors of in-hospital mortality of elderly patients with moderate to severe TBI who presented during the Coronavirus disease 2019 (COVID-19) pandemic. METHODS: In this retrospective analytical study, all elderly patients with moderate to severe TBI who were referred to our center between March 2nd, 2020 to August 1st, 2020 were investigated and compared against the TBI patients receiving treatment during the same time period within the year 2019. Patients were followed until discharge from the hospital or death. The demographic, clinical, radiological, and laboratory test data were evaluated. Data were analyzed using SPSS-21 software. FINDINGS: In this study, 359 elderly patients were evaluated (n = 162, Post-COVID-19). Fifty-four patients of the cohort had COVID-19 disease with a mortality rate was 33.3%. The patients with COVID-19 were 5.45 times more likely to expire before discharge (P < 0.001) than the TBI patients who were not COVID-19 positive. Other variables such as hypotension (OR, 4.57P < 0.001), hyperglycemia (OR, 2.39, P = 0.002), and use of anticoagulant drugs (OR, 2.41P = 0.001) were also associated with in-hospital death.According to the binary logistic regression analysis Age (OR, 1.72; 95% CI: 1.26-2.18; P = 0.033), Coronavirus infection (OR, 2.21; 95% CI: 1.83-2.92; P = 0.011) and Glasgow Coma Scale (GCS) (OR, 3.11; 95% CI: 2.12-4.53; P < 0.001) were independent risk factors correlated with increased risk of in-hospital mortality of elderly patients with moderate to severe TBI. CONCLUSION: Our results showed that Coronavirus infection could increase the risk of in-hospital mortality of elderly patients with moderate to severe TBI significantly.

ABSTRACT

BACKGROUND: Sacroiliac joint hypermobility or aberrant mechanics may be a source of pain. The purpose of this study was to assess sacroiliac joint range of motion after simulated adjacent lumbosacral instrumented fusion, with or without sacroiliac joint fusion, with lateral sacroiliac screws. METHODS: In this in vitro biomechanical study, seven cadaveric specimens were tested on a six-degrees-of-freedom machine under load control. Left posterior sacroiliac joint ligaments were severed to maximize joint range of motion. Influence of lumbosacral instrumentation on sacroiliac joint motion, with or without fixation, was studied. FINDINGS: During flexion-extension in the setting of posterior sacroiliac joint injury and L5-S1 fixation, sacroiliac joint range of motion increased to 195% of intact. After fixation with lateral sacroiliac screws, average range of motion reduced to 144% of intact motion. Sacroiliac joint screws thus partially stabilized the joint and reduced motion. Use of 6 bilateral sacroiliac joint screws with L5-S1 screw and rod fixation in lateral bending and axial rotation yielded the greatest reduction in range of motion. Without lumbosacral fixation, baseline motion of the sacroiliac joint was reduced, and sacroiliac joint screw alone, using either 2, 3, or 6 screws, was able to restore motion at or below the level of an intact joint. INTERPRETATION: Sacroiliac joint ligament injury with existing lumbosacral fixation doubled sacroiliac joint range of motion, but thereafter, fixation with lateral sacroiliac screws decreased range of motion of the injured sacroiliac joint. Screw configuration played a minor role, but generally, 6 sacroiliac joint screws had the greatest motion reduction.
