Role of Altmetric Attention Scores in Evaluating the Influence of Spine Surgery Research.

Study Design: Retrospective cohort.

Objective: To analyze the annual trends in the most prevalent topics, journals, and geographic regions of the top 100 spine surgery articles, as determined by altmetric attention scores (AASs). We also describe the relationship between AAS and traditional article metrics.

Higher socioeconomic status is associated with greater rates of surgical resource utilization prior to spine fusion surgery.

Background Context: Previous research has demonstrated an association between socioeconomic status (SES) and patient health, specifically noting that patients of lower SES have poor health outcomes. Understanding how social factors, including socioeconomic status (SES), relate to disparities in health outcomes is critical to closing gaps in equitable care to patients. While several studies have examined the effect of SES on postoperative spine outcomes, there is limited spine literature evaluating SES in the context of barriers to spine care.

Postoperative Ketamine May be Associated with Venous Thromboembolism in Chronic Opioid Users After Spine Surgery.

Objective: Venous thromboembolism (VTE) is a serious postoperative adverse event after spine surgery. In patients with pain refractory to typical multimodal analgesia regimens after spine surgery, whom are often chronic opioid users, perioperative ketamine is an alternative analgesic that has grown in popularity. The aim of this study is to assess the risk of VTE in chronic opioid users undergoing spine surgery.

The Effect of Community-Level Socioeconomic Status on Surgical Outcomes Following Revision Lumbar Fusion.

Background: The purpose of this study is to determine the impact of community-level socioeconomic status (SES) on surgical outcomes and patient-reported outcome measures (PROMs) following revision lumbar fusion.

Methods: Adult patients who underwent revision lumbar fusion surgery from 2011-2021 were grouped by Distressed Community Index (DCI) into Prosperous, Comfortable, Mid-tier, and At-Risk/Distressed cohorts. Demographics, surgical information, and PROMs were compared based on DCI community status.

One-year patient reported outcomes after single-level lumbar fusion at orthopedic specialty hospital compared to tertiary referral center.

Background Context: Lumbar spinal fusion is an increasingly common operation to treat symptoms related to degenerative disorders of the spine including radiculopathy and pain. As the volume of spine surgeries grows, it is becoming increasingly common for procedures to take place in nontertiary care centers, including orthopaedic specialty hospitals (OSH). While previous research demonstrates that surgical outcomes at an OSH are noninferior to those at a tertiary referral center (TRC), the implications of this difference on patient-reported outcome measures (PROMs) have not been sufficiently assessed.

Socioeconomic Status Impacts Length of Stay and Nonhome Discharge Disposition After Posterior Cervical Decompression and Fusion.

Study Design: Retrospective cohort study.

Summary Of Background Data: There is a relatively high rate of the need for repeat decompression or fusion after an index decompression procedure for degenerative spine disease.

Which North American spine society disc herniation morphology descriptors are most associated with improvements in clinical outcomes after microdiscectomy?

Background: The North American Spine Society (NASS) assembled the first ever comprehensive naming system for describing lumbar disc disease, including lumbar disc herniation. The objectives of this study were (1) to determine which NASS descriptors are most predictive of independent patient-reported outcomes after microdiscectomy and (2) to identify the inter-rater reliability of each NASS descriptor.

Methods: Adult patients (≥18 years) who underwent a lumbar microdiscectomy from 2014-2021 were retrospectively identified.

Factors Related to Clinical Performance in Spine Surgery Fellowship: Can We Predict Success.

Introduction: The factors most important in the spine fellowship match may not ultimately correlate with quality of performance during fellowship. This study examined the spine fellow applicant metrics correlated with high application rank compared with the metrics associated with the strongest clinical performance during fellowship.

Methods: Spine fellow applications at three academic institutions were retrieved from the San Francisco Match database (first available to 2021) and deidentified for application review.

The Impact of the Preoperative Mental Health Component Summary (MCS) Score on Short-term Outcomes after Lumbar Fusion.

Study Design: Retrospective cohort study.

Objective: The purpose of this study is to characterize the relationship between preoperative MCS and surgical outcomes after lumbar spine surgery including inpatient complications, length of stay, readmissions, and reoperations.

Summary Of Background Data: As the prevalence of mental health disorders in the United States increases, it is important to identify risks associated with poor mental health status in the surgical spine patient.

Does Paraspinal Muscle Mass Predict Lumbar Lordosis Before and After Decompression for Degenerative Spinal Stenosis?

Study Design: Retrospective cohort study.

Objective: The purpose of this study was to determine whether muscle mass and quality of the lumbar paraspinal muscles was associated with improvements in lumbar lordosis and other sagittal parameters after isolated posterior lumbar decompression surgery for lumbar spinal stenosis.

Summary Of Background Data: Individuals may develop sagittal imbalance over time, either due to degenerative changes or other spinal conditions.

The Relationship Between Disc Herniation Morphology and Patient-Reported Outcomes after Microdiscectomy.

Objective: Determine if herniation morphology based on the Michigan State University Classification is associated with differences in (1) patient-reported outcome measures (or (2) surgical outcomes after a microdiscectomy.

Methods: Adult patients undergoing single-level microdiscectomy between 2014 and 2021 were identified. Demographics and surgical characteristics were collected through a query search and manual chart review.

Relating preoperative MCS-12 to microdiscectomy outcomes.

Purpose: To determine the impact of poor mental health on patient-reported and surgical outcomes after microdiscectomy.

Methods: Patients ≥ 18 years who underwent a single-level lumbar microdiscectomy from 2014 to 2021 at a single academic institution were retrospectively identified. Patient-reported outcomes (PROMs) were collected at preoperative, three-month, and one-year postoperative time points.

Radiology Reports Do Not Accurately Portray the Severity of Cervical Neural Foraminal Stenosis.

Study Design: Retrospective study.

Objective: (1) To compare cervical magnetic resonance imaging (MRI) radiology reports to a validated grading system for cervical foraminal stenosis (FS) and (2) to evaluate whether the severity of cervical neural FS on MRI correlates to motor weakness or patient-reported outcomes.

Background: Radiology reports of cervical spine MRI are often reviewed to assess the degree of neural FS.

Significance of Facet Fluid Index in Anterior Cervical Degenerative Spondylolisthesis.

Study Design: Retrospective cohort study.

Purpose: To correlate cervical facet fluid characteristics to radiographic spondylolisthesis, determine if facet fluid is associated with instability in cervical degenerative spondylolisthesis, and examine whether vertebral levels with certain facet fluid characteristics and spondylolisthesis are more likely to be operated on.

Overview Of Literature: The relationship between facet fluid and lumbar spondylolisthesis is well-documented; however, there is a paucity of literature investigating facet fluid in degenerative cervical spondylolisthesis.

Utilization of In-Hospital Orthopaedic Spine Consultations: Evaluating the Impact of Health Care Policy.

Access to specialty and private practice providers has been a divisive policy issue over the last decade, complicated by the conflict between a reduction in government-funded health care reimbursement and the need for health care providers to sustain a financially sound practice. This study evaluates the orthopedic spine consult service at an academic tertiary care center at 2 separate time points over a 5-year period to better understand the impact of decreasing orthopedic reimbursement rates and the increasing prevalence of federally supported medical insurance on the access to specialty care. In total 500 patients in 2017 and 480 patients in 2021 were included for the final analysis.

Lateral approach to the lumbar spine: The utility of an access surgeon.

Background: Lateral lumbar interbody fusions (LLIFs) utilize a retroperitoneal approach that avoids the intraperitoneal organs and manipulation of the anterior vasculature encountered in anterior approaches to the lumbar spine. The approach was championed by spinal surgeons; however, general/vasculature surgeons may be more comfortable with the approach.

Objective: The objective of this study was to compare short-term outcomes following LLIF procedures based on whether a spine surgeon or access surgeon performed the approach.
