Study Design: Retrospective Cohort Study.

Objectives: Although the optimal timing of surgical intervention for traumatic spinal cord injury (TSCI) is controversial, early intervention has been recognized as being beneficial in several studies. The objective of this study was to evaluate the socioeconomic factors that may delay time to surgical fixation in the management of TSCI.

Background: Historically, Charcot neuroarthropathy hip (CNH) was deemed a contraindication for total hip arthroplasty (THA). However, as implant design and surgical techniques advance, THA for CNH has been performed and documented in literature. Information regarding the outcomes of THA for CNH is limited.

Purpose: The purpose of this study was to use a national claims database to assess the impact of pre-existing social determinants of health disparities (SDHD) on postoperative outcomes following rotator cuff repair (RCR).

Methods: A retrospective review of the Mariner Claims Database was used to capture patients undergoing primary RCR with at least 1 year of follow-up. These patients were divided into two cohorts based on the presence of a current or previous history of SDHD, encompassing educational, environmental, social, or economic disparities.

Objective: The purpose of this study was to analyze if celiac disease (CD) is associated with increased postoperative complications following single-level posterior lumbar fusion (PLF).

Methods: A retrospective database review was performed using the PearlDiver dataset. The study population included all patients older than 18 years who underwent elective PLF with diagnosis of CD using International Classification of Diseases (ICD) and Current Procedural Terminology (CPT) codes.

Background: The use of carbon fiber or polyetheretherketone spine constructs has proven to be a safe and effective alternative to standard metal alloy. The mechanical properties of carbon fiber while unique provide a construct that is comparable in strength to previous titanium-based constructs and have additionally shown greater fatigue resistance. These constructs have been especially useful for the mechanical stabilization of the spine following tumor resection.

Fellowship directors are assumed to be distinguished in orthopedics, but the traits and training that have enabled them to achieve their leadership positions have not been assessed. : We sought to identify common demographics, research output, and educational trends of fellowship directors in orthopedics, with an emphasis on racial, ethnic, and gender diversity. : We conducted a literature review to identify published studies on fellowship directors in orthopedic surgery and found 4 cross-sectional studies of fellowship directors in spine, arthroplasty, pediatrics, and sports medicine subspecialties.

Objective: Cervical spondylotic myelopathy (CSM) is a progressive degenerative condition that can lead to significant neurological deficits, including gait instability. Biomechanical alterations of gait and its various components are poorly understood. The goal of the current study was to determine how spatiotemporal gait parameters, as well as postural and dynamic stability, change after surgery in CSM patients.

Objective: The two most common revision options available for the management of loose pedicle screws are larger-diameter screws and cement augmentation into the vertebral body for secondary fixation. An alternative revision method is impaction grafting (pedicoplasty) of the failed pedicle screw track. This technique uses the impaction of corticocancellous bone into the pedicle and vertebral body through a series of custom funnels to reconstitute a new pedicle wall and a neomedullary canal.

Study Design: Retrospective database analysis.

Objectives: To study postoperative complication rates following anterior cervical discectomy and fusion (ACDF) in patients with Ehlers-Danlos syndrome (EDS) compared with patients without EDS.

Methods: The Mariner database was utilized to identify patients with EDS undergoing one or two level anterior cervical discectomy and fusion (ACDF).

Purpose: The purpose of the current study was to use a nationwide administrative-claims database to characterize the substance use disorder trends of patients undergoing arthroscopic rotator cuff repair (RCR). Additionally, we sought to evaluate the influence of preoperative substance use disorder on postoperative outcomes following arthroscopic RCR.

Methods: The Mariner database was used to identify patients undergoing RCR using CPT codes, ages 18-84 years old, from 2010 to 2019.

Study Design: Retrospective Cohort.

Objective: This study utilized a large national database to compare two-year revision rates, in addition to complications and costs, of hybrid surgery (HS) compared to two-level anterior cervical discectomy and fusion (ACDF).

Methods: This study used the PearlDiver Mariner dataset selecting for patients aged 18 and older who had at least 90-day active longitudinal follow-up who underwent two-level ACDF or two-level Hybrid surgery (single level ACDF and single level CDA).

Background: There is limited literature exploring how nonmedical factors such as social determinants of health (SDOHs) are associated with postoperative outcomes following shoulder arthroplasty.

Methods: A retrospective cohort review of the Pearl Diver Database was used to capture patients undergoing either primary anatomic total or reverse shoulder arthroplasty from the fourth quarter of 2015 to the third quarter of 2019 with at least 1 year of active longitudinal follow-up. Patients with proximal humeral fractures, stress fractures, or septic arthritis were excluded.

Study Design: Retrospective cohort.

Objective: To analyze and confirm the rates of postoperative complications of patients with hepatitis C virus (HCV) undergoing primary posterior lumbar fusion (PLF) and assess whether treatment of HCV before surgery reduces complications.

Background Context: HCV causes chronic disease, leading to increased risk of cirrhosis and chronic illness.

Study Design: Retrospective-Cohort INTRODUCTION: Dementia is among the most common health concerns for the aging population, characterized by steep cognitive decline and subsequent loss of independence. Limited orthopedic literature examines the influence that dementia has on patients undergoing elective spinal surgeries.

Methods: Employing the PearlDriver Database, a study population consisting of patients who underwent primary elective ACDF with a prior diagnosis of dementia were selected using Internal Classification Disease-9 (ICD) and ICD-10 codes.

Objective: To determine if a penicillin allergy is an independent risk factor for poor outcomes after anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF).

Methods: A retrospective database review was performed using the PearlDiver data set. The study population included all patients younger than 85 years who underwent elective PLF or ACDF with diagnosis of penicillin allergy using International Classification of Diseases codes.

Study Design: Retrospective Review INTRODUCTION/OBJECTIVE: The aim of this study is to utilize a national database to identify how age affects patient outcomes following anterior lumbar interbody fusion (ALIF). There are no established age guidelines for the geriatric population within the spine specialty, which makes patient selection challenging. Furthermore, there are conflicting studies for the risks of performing spine surgeries in the elderly.

Study Design: Retrospective cohort study.

Objective: The aim were to (1) evaluate differences in postoperative outcomes and cost associated with outpatient anterior lumbar interbody fusion (ALIF) compared with inpatient ALIF, and to (2) identify independent factors contributing to complications after outpatient ALIF.

Summary Of Background: While lumbar fusion is traditionally performed inpatient, outpatient spinal surgery is becoming more commonplace as surgical techniques improve.
