Background: Anterior cervical discectomy and fusion (ACDF) is a common surgery for patients with degenerative cervical disease and current interbody spacers utilized vary based on material composition, structure, and angle of lordosis. Currently, there is a lack of literature comparing subsidence rates or long-term radiographic outcomes with hyperlordotic and standard lordotic spacers. This study compares long-term radiographic outcomes, subsidence rate, and rate of fusion in patients who underwent ACDF with hyperlordotic or standard interbody placement.

Methods: Patients who underwent a 1-3 level revision lumbar fusion from 2011-2021 were included. Patients were grouped into BMI classes: Normal (18.
Study Design: Retrospective cohort study.
Objective: To determine hospital length of stay (LOS) and long-term opioid consumption among patients who received inpatient multimodal analgesia following lumbar spine surgery, as opposed to those who received opioids alone.
Summary Of Background Data: Opioids have long been the historical choice for managing postoperative pain.
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.
Study Design: Retrospective cohort.
Objective: To explore the relationship between symptomatic pseudoarthrosis requiring revision after lumbar fusion and antidepressant use.
Summary Of Background Data: Approximately 25% of patients undergoing spine surgery are taking antidepressants.
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.

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.
Article Synopsis
- The study is a narrative review analyzing existing literature on the timing of surgeries for cervical trauma, specifically focusing on acute traumatic central cord syndrome, which is a common incomplete spinal cord injury.
- Recent consensus in clinical literature supports the safety and efficacy of early surgical intervention (within 24 hours) to alleviate the condition and respond to ischemic injury.
- Despite this emerging agreement, additional research is needed to determine the best timing for surgeries, particularly for ultra-early interventions (within 8 hours), and to improve patient screening processes.
Study Design: Retrospective cohort study.
Objective: To compare peri- and postoperative infection rates among patients with mild to moderate penicillin allergies who receive cefazolin vs vancomycin as prophylaxis for lumbar fusion. Additionally, we sought to determine if patients receiving cefazolin exhibited any clinical symptoms suggestive of drug-induced hypersensitivity reactions, and to compare those rates to patients who received vancomycin.
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.

Summary Of Background Data: A range of measures, including implementation of state prescription drug monitoring programs, have been instituted to combat the opioid epidemic. Considering the continued presence of opioids for spine-related pain management, a better understanding of the patterns of opioid prescription practices may be important for future intervention.
Study Design: Retrospective cohort study.
Objective: To examine how community-level economic disadvantage impacts short-term outcomes following posterior cervical decompression and fusion (PCDF) for cervical spondylotic myelopathy.
Summary Of Background Data: The effects of socioeconomic factors, measured by the Distress Community Index (DCI), on postoperative outcomes after PCDF are underexplored.
Study Design: Retrospective cohort study.
Objective: The purpose of this study is to determine which demographic, surgical, and radiographic preoperative characteristics are most associated with the need for subsequent fusion after decompression lumbar spinal surgery.
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.
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.
Article Synopsis
- The study aimed to examine how resilience affects pain and neck disability outcomes in patients who had single- or double-level anterior cervical discectomy and fusion (ACDF).
- Patients completed surveys on resilience, pain, and disability levels both before and after surgery, allowing researchers to categorize them based on their resilience levels.
- Results showed that all patients improved post-surgery, but those with higher resilience reported better pain relief compared to those with lower resilience, indicating resilience may play a role in recovery outcomes.
Construct length analysis of type B and C cervical and thoracolumbar fractures.
J Craniovertebr Junction Spine
May 2024
Objectives: The purpose of this study is to identify if construct length affects the rate of surgical complications and instrumentation revision following surgical fixation of subaxial and thoracolumbar Type B and C fractures. This study evaluates the effect of ankylosing spondylitis/diffuse idiopathic skeletal hyperostosis (AS/DISH) within this population on outcomes.
Methods: Retrospective review of 91 cervical and 89 thoracolumbar Type B and C fractures.
Article Synopsis
- The study is a retrospective comparison of outcomes for lumbar fusion surgeries at various hospital types: an orthopedic specialty hospital, a hybrid community hospital, a conventional community hospital, and a tertiary care hospital.
- It found that patients at the tertiary care hospital had longer hospital stays and higher readmission rates compared to those at the orthopedic specialty hospital and hybrid community hospital, indicating a potential advantage for specialized care.
- Overall, the results suggest that orthopedic specialty hospitals may lead to shorter recovery times and better discharge outcomes compared to more conventional hospital settings.
Study Design: Retrospective Cohort.
Objective: To compare patient-reported outcomes and surgical outcomes after anterior cervical discectomy and fusion (ACDF) versus cervical laminoplasty for multilevel cervical spondylotic myelopathy.
Background: Treatment options for multilevel cervical spondylotic myelopathy include ACDF and cervical laminoplasty.
Article Synopsis
- The study investigates opioid prescription and use patterns in patients who undergo cervical spine fusion surgery, focusing on both traumatic and elective cases.
- It employs a retrospective cohort design, assessing demographic and clinical data from adult patients with traumatic cervical injuries and matching them with elective surgery patients.
- Outcome measures include detailed analysis of pre- and postoperative opioid and medication use, with findings standardized in morphine milligram equivalents to compare consumption between the two patient groups.
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.
Article Synopsis
- - The study is a retrospective cohort analysis aimed at determining if the L1 pelvic angle (L1PA) can predict quality of life outcomes one year after lumbar fusion surgery for degenerative spondylolisthesis in adults.
- - Researchers grouped patients based on their preoperative and postoperative L1PA measurements and compared patient-reported outcomes (PROMs) along with radiographic data, finding correlations with pelvic parameters but no significant differences in quality of life outcomes.
- - The conclusion suggests that while L1PA shows some correlations with pelvic measurements, it does not significantly distinguish quality of life improvements post-surgery, indicating further exploration is needed on its utility in these patients.
Article Synopsis
- Double-crush syndrome (DCS) involves both peripheral nerve compression and spinal nerve root impingement, and this study aimed to compare electrodiagnostic results in patients undergoing carpal tunnel release (CTR) versus those also receiving cervical diskectomy and fusion for DCS.
- The study analyzed data from 54 DCS patients and 137 CTR-only patients, noting that DCS patients had shorter sensory latencies, slower wrist motor velocity, and positive EMG findings in muscles like the biceps and triceps.
- The findings suggest that DCS patients exhibit distinct electrodiagnostic patterns compared to CTR-only patients, emphasizing the need for healthcare providers to consider cervical issues when encountering related EMG abnormalities.
Objectives: To evaluate the (1) 90-day surgical outcomes and (2) 1-year revision rate of robotic versus nonrobotic lumbar fusion surgery.
Methods: Patients >18 years of age who underwent primary lumbar fusion surgery at our institution were identified and propensity-matched in a 1:1 fashion based on robotic assistance during surgery. Patient demographics, surgical characteristics, and surgical outcomes, including 90-day surgical complications and 1-year revisions, were collected.
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.
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.
