Increasing incidence of concussion and head injury due to electric biking: a 10-year sex- and age-specific analysis of national injury data.

Objectives: Electric biking (e-biking) is a rapidly growing recreation, sport, and mode of transportation that often presents to emergency departments (EDs) with high-impact head injuries. This study aimed to evaluate the epidemiology of e-bike-related concussions and closed-head injuries (CHI) to inform more effective injury prevention strategies.

Methods: The National Electronic Injury Surveillance (NEISS) was queried for e-bike related concussions and CHIs presented to national EDs from 1 January 2013-31 December 2022.

Regular Physician Access and Obesity Status Among Underserved Asian and Pacific Islander American Immigrants in Los Angeles.

According to prior research, Asian and Pacific Islander American (APIA) immigrants often refrain from seeking health care unless necessitated by medical conditions. Utilizing data from health screenings conducted in APIA immigrant enclaves in Los Angeles, we hypothesize that poorer obesity status would predict higher rates of regular physician access. Analyses involved objectively measured percent body fat (%BF) and survey responses collected between 2011 and 2019.

Structural Allograft Versus Mechanical Interbody Devices Augmented With Osteobiologics in Anterior Cervical Discectomy and Fusion: A Systematic Review.

Study Design: Systematic Literature Review.

Objective: Perform a systematic review evaluating postoperative fusion rates for anterior cervical discectomy and fusion (ACDF) using structural allograft vs various interbody devices augmented with different osteobiologic materials.

Methods: Comprehensive literature search using PubMed, Embase, The Cochrane Library, and Web of Science was performed.

Abnormal Postoperative PROMIS Scores are Associated With Patient Satisfaction in Adult Spinal Deformity and Degenerative Spine Patients.

Study Design: Retrospective review.

Objectives: To evaluate (1) patient satisfaction after adult spine surgery; (2) associations between the number of abnormal PROMIS domain scores and postoperative satisfaction; and (3) associations between the normalization of a patient's worst preoperative PROMIS domain score and postoperative satisfaction.

Summary Of Background Data: Although "legacy" patient-reported outcome measures correlate with patient satisfaction after adult spine surgery, it is unclear whether PROMIS scores do.

Racial and Socioeconomic Disparities in Risk and Reason for Revision in Total Joint Arthroplasty.

Introduction: Data regarding racial/ethnic and socioeconomic differences in revision total hip arthroplasty (rTHA) and revision total knee arthroplasty (rTKA) have been inconsistent. This study examined racial/ethnic and socioeconomic disparities in comorbidity-adjusted risk and reason for rTHA and rTKA.

Methods: Patients who underwent rTHA or rTKA between 2006 and 2014 in the National Inpatient Sample were identified.

Disparities in Telemedicine Literacy and Access in the United States.

Background: Because of the expansion of telehealth services through the 2020 Coronavirus Aid, Relief, and Economic Security (CARES) Act, the potential of telemedicine in plastic surgery has gained visibility. This study aims to identify populations who may have limited access to telemedicine.

Methods: The authors created a telemedicine literacy index (TLI) using a multivariate regression model and data from the US Census and Pew Research Institute survey.

Are There Racial and Ethnic Disparities in Management and Outcomes of Surgically Treated Distal Radius Fractures?

Background: Racial/ethnic disparities have been demonstrated across multiple orthopedic sub-specialties. There is a paucity of literature examining disparities in distal radius fracture (DRF) management.

Methods: Using the National Surgical Quality Improvement Program database, we analyzed 15 559 non-Hispanic (NH) White, NH Black, NH Asian, and Hispanic adults who underwent open reduction and internal fixation for DRF from 2013 to 2019.

Disparity in Obesity and Hypertension Risks Observed Between Pacific Islander and Asian American Health Fair Attendees in Los Angeles, 2011-2019.

Introduction: The Pacific Islander American population is understudied due to being aggregated with Asian Americans. In this study, we conduct a comparative analysis of directly measured body mass index (BMI), body fat percentage (%BF), and blood pressure (BP) between Pacific Islander Americans and Asian Americans from health screenings in Los Angeles, California. We hope to reveal intra-APIA health disparities masked by this data aggregation.

Does Time to Imaging and Surgery for Distal Radius Fractures Vary based on Geographic Socioeconomic Disadvantage?

Background: While disparities in aspects of distal radius fracture (DRF) management and orthopedics at large have been studied, disparities in time to DRF evaluation and treatment are unknown. We sought to determine if geographic socioeconomic disadvantage is associated with time to imaging in the emergency department (ED) and time to surgery for DRFs.

Methods: We performed a time-to-event analysis of 105 patients undergoing DRF surgery after ED triage within our hospital system between January 1, 2015, and January 1, 2020.

Trends in Health Care Access Disparities Among Asian and Pacific Islander Health Fair Participants in Los Angeles, 2011-2019.

Objectives: Given several efforts to improve health care access in California and nationally, we studied whether linguistic and socioeconomic disparities in health care access changed from 2011 to 2019 among Asian and Pacific Islander American (APIA) people in Los Angeles, California.

Methods: We analyzed survey responses from APIA health fair participants (n = 5032) in the Greater Los Angeles area from May 15, 2011, through October 20, 2019. To assess the effect of socioeconomic factors on and shifts in health care access (ie, health insurance status/regular doctor), we used a logistic regression model.

Pediatric Back Pain Associated with Bertolotti Syndrome: A Report of 3 Cases with Varying Treatment Strategies.

Case: Three pediatric patients with back pain associated with Bertolotti syndrome are presented. After failing conservative management, 1 patient underwent mega-apophysis resection, another underwent resection with decompression, and the final underwent posterior fusion. All patients had complete resolution of back pain and returned to full activity at final follow-up.

COVID-19 Significantly Impacted Hospital Length of Stay and Discharge Patterns for Adult Spinal Deformity Patients.

Study Design: Retrospective review.

Objective: The primary aim was to compare length of stay (LOS) and discharge disposition of adult spinal deformity (ASD) patients undergoing surgery before and during the pandemic. Secondary aims were to compare the rates of 30-day complications, reoperations, readmissions, and unplanned emergency department (ED) visits.

Geographic Variation in Physician Payments from Private Insurers for Commonly Performed Inpatient Orthopaedic Surgeries in the United States.

We investigated geographic variation in percentage of private insurance payments to United States physicians for commonly performed orthopaedic procedures. We queried a private administrative claims database for patients who underwent inpatient total knee arthroplasty (TKA), total hip arthroplasty (THA), single-level anterior cervical discectomy and fusion (ACDF), and posterior lumbar fusion (PLF) from 2010 to 2017. Percentage of total payments to physician (PPP) was calculated by dividing physician payments by total payments.

Annual Trends and Geographic Variation in the Utilization of Imaging in Pediatric Patients with Low Back Pain in the United States.

Background: Low back pain (LBP) is increasing in the pediatric population. Advanced imaging, such as computed tomography and magnetic resonance imaging, performed for LBP imposes significant costs with little benefit. We investigated annual trends and demographic and geographic variation in spinal imaging for first-time pediatric presenters with LBP in primary care clinics.

APA Health CARE: A Student-Led Initiative Addressing Health Care Barriers Faced by the Asian and Pacific Islander American Immigrant Population in Los Angeles.

Asian and Pacific Islander Americans face cultural, linguistic, and financial barriers to accessing health care. APA Health CARE (APAHC), a UCLA student-led organization, attempts to bridge these disparities through free community health screenings, health education seminars, and follow-up procedures. From 2011 to 2018, participants' demographic and health-related information were recorded during health fairs and follow-up phone calls.
