Association of Alcohol Use Disorder and Perioperative Complications and Adverse Events After Spinal Fusion Surgery During the In-hospital Period: An Analysis of the National Inpatient Sample (NIS) Database.

Objective: Alcohol use disorder carries major effects shown to limit social support, increase recovery times, and lead to a higher incidence of surgical complications. This retrospective cohort study investigated the influence of AUD on perioperative outcomes and adverse events after spinal fusions in the largest sample size to date and spanning 11 years.

Methods: Data for adult (>18 years old) patients who underwent a spinal fusion as their primary surgery were identified from the Nationwide Inpatient Sample (NIS) database for the years 2009-2020.

Definition of cage subsidence in transforaminal lumbar interbody fusion (TLIF) approach and posterior lumbar interbody fusion (PLIF) approach - A systematic review.

Background: Although cage subsidence is one of the most common phenomenona associated with interbody fusions and was characterized more than 70 years ago, a standardized method for its measurement, detection, and reporting among different lumbar fusion procedures does not exist. Here, we review previously published literature on cage subsidence to present the most common methods for defining subsidence in the posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) techniques.

Methods: A search was completed in PubMed and Embase with inclusion criteria focused on identifying any study that provided descriptions of the method, imaging modality, and subsidence threshold used to define the presence of cage subsidence in study articles published between January 1, 2001 and December 31, 2022.

Treatment Strategies for Intermediate Spinal Instability Neoplastic Score (SINS 7-12) Patients: A Systematic Review.

Background: The Spinal Instability Neoplastic Score (SINS) is used in determining instability in patients with spinal metastases. Intermediate scores of 7 to 12 suggest possible instability, but there are no clear guidelines to address patients with these scores.

Methods: We searched in PubMed, EMBASE, and Cochrane databases for studies that included patient demographics, tumor histology, surgical or radiotherapy management, and outcomes of patients with intermediate SINS.

Association Between Median Household Income and Perioperative Outcomes of Lumbar Spinal Fusion: An Analysis of the National Inpatient Sample (2009-2020).

Background: Relationships between low socioeconomic status and surgical outcomes are well established for certain procedures. However, scant literature has focused on relationships between median household income and lumbar fusion outcomes.

Methods: Patients who underwent fusion procedures between January 1, 2009 and December 31, 2020 were identified from the National Inpatient Sample database.

Correlations Between Psychiatric Disorders and Perioperative Outcomes After Lumbar Fusions: An Analysis of the National Inpatient Sample (2009-2020).

Background: Preoperative diagnoses of psychiatric disorders have a demonstrated association with higher rates of perioperative complications. However, recent studies examining the influence of psychiatric disorders on lumbar fusion outcomes are scarce. Our objective was to determine the relationship between the most common psychiatric disorders and perioperative outcomes after lumbar fusion.

The Effect of Varying Preoperative Hemoglobin Levels on the Risk of Major Complications and Surgical Site Infections After Single Level Lumbar Fusion.

Introduction: Blood transfusions are associated with an increased risk of complications after lumbar fusion, and current anemia hemoglobin thresholds are not surgery specific. We aimed to calculate single-level lumbar fusion-specific preoperative hemoglobin strata that observe the likelihood of 90-day transfusion and evaluate whether these strata are associated with increased risk of 90-day complications and 2-year infections.

Methods: A national database identified patients undergoing primary single-level lumbar fusion with preoperative hemoglobin values (g/dL).

Comparative analysis of patient demographics, perioperative outcomes, and adverse events after lumbar spinal fusion between urban and rural hospitals: an analysis of the National Inpatient Sample (NIS) database.

Objective: Rural location of a patient's primary residence has been associated with worse clinical and surgical outcomes due to limited resource availability in these parts of the US. However, there is a paucity of literature investigating the effect that a rural hospital location may have on these outcomes specific to lumbar spine fusions.

Methods: Using the National Inpatient Sample (NIS) database, we identified all patients who underwent primary lumbar spinal fusion in the years between 2009 and 2020.
