Surgical subspecialist distribution and Social Vulnerability Indices in the inland empire.

Background: Access to surgical specialty care differs based on geographic location, insurance status, and subspecialty type. This study uses the Inland Empire as a model to determine the relationship between Social Vulnerability Indices (SVIs), surgeon sex, and surgical subspecialty distribution.

Methods: 823 census tracts from the Centers for Disease Control's (CDC) SVI 2018 database were compared against 992 surgeons within 30 distinct subspecialties.

Does Marijuana Smoking Increase the Odds of Surgical Site Infection After Orthopaedic Surgery? A Retrospective Cohort Study.

Objectives: Does marijuana smoking increase the risk of surgical site infection (SSI) after open reduction and internal fixation of fractures?

Design: Retrospective.

Setting: Single academic level 1 trauma center in Southern California.

Patient Selection Criteria: Adult patients who underwent open treatment for closed fractures between January 2009 and December 2021, had hardware placed, and had at least 6 months of postoperative follow-up.

A Look Into How the "Blue Zone" Lifestyle May Affect Patients' Lives Before and After Hip Fracture: A Propensity-Matched Cohort Study.

Introduction: Hip fractures are life-changing injuries with associated one-year mortality up to 30%. Five locations in the world have been termed "blue zones," where the longevity of the population is markedly higher than that of surrounding areas and there are 10 times more centenarians. The United States has one blue zone (Loma Linda, California), which is believed to be because of the lifestyle of the Seventh-day Adventist population living there.

Analyzing the association between social vulnerability indexes and surgically underserved areas in the Inland Empire.

Background: The United States lacks equitable surgical access, prompting us to investigate whether there is an inverse relationship between Social Vulnerability Indices and the number of surgeons in a census tract, using the Inland Empire as a model.

Methods: The Centers for Disease Control's (CDC) SVI 2018 database, composed of 823 census tracts, was compared against demographics of 1008 surgeons, from the American Medical Association's (AMA) 2018 Physician Masterfile. Analysis was performed via Spearman's bivariate and multiple regression.

Do All-terrain or Recreational Off-highway Vehicle Crashes Have a Higher Odds of Amputation?

Background: Riding off-road vehicles is associated with the risk of injury to the extremities. There are two main types of four-wheel recreational off-road vehicles: quads or all-terrain vehicles (ATVs), which are essentially four-wheel off-road motorcycles, and recreational off-highway vehicles (ROVs), also colloquially referred to as utility terrain vehicles, which have side-by-side seating, higher maximum speeds, and a roll cage. There are multiple orthopaedic society position statements on ATVs, but none on ROVs.

Report on the Evidence-Based Practice Committee's Survey on Dupuytren Disease.

Purpose: The Evidence-Based Practice Committee of the American Society for Surgery of the Hand (ASSH) set out to assess the membership's practice patterns (PPs) and knowledge of evidence-based principles for Dupuytren disease (DD).

Methods: A 21-item multiple-choice survey was distributed to all ASSH members via email in June 2020. Questions were divided into 2 types: evidence-based practice (EBP) and PPs.

Calcium released by osteoclastic resorption stimulates autocrine/paracrine activities in local osteogenic cells to promote coupled bone formation.

A major cause of osteoporosis is impaired coupled bone formation. Mechanistically, both osteoclast-derived and bone-derived growth factors have been previously implicated. Here, we hypothesize that the release of bone calcium during osteoclastic bone resorption is essential for coupled bone formation.

Effect of Remote Proctoring of the Orthopaedic In-training Examination on Scores.

Introduction: The pandemic has created an opportunity to explore different testing settings. However, transitioning to remote testing raises concerns about cheating. The possibility of cheating raises concern about the integrity of test psychometrics.

Intramedullary Suture Anchor Fixation of a Type Vb Flexor Digitorum Profundus Avulsion: A Case Report.

Case: Flexor digitorum profundus avulsions are common injuries that manifest as tendinous or bony avulsions from the distal phalanx. Rarely, additional fractures can occur in the distal phalanx. For such injuries, repair of the avulsion and fracture is recommended but difficult because of limited bone stock for fixation.

Visual Estimation of Length by Orthopaedic Surgeons: How Accurate Are Lengths Estimated in Digital Images Compared to In-Person Estimations?

Orthopaedic surgeons are frequently required to make estimations, often without the use of measuring tools, including the lengths of wounds, incisions, bone fragments, and soft tissue defects. To evaluate the accuracy of these estimations, simulated wounds of randomized lengths were drawn on a healthy volunteer. Resident and attending physicians estimated the length of each wound via digital photograph and subsequently in person.

COVID-19 pandemic and the implications for orthopaedic and neurosurgery residents and fellows on spine rotations.

Background: The COVID-19 global pandemic has caused unprecedented levels of strain on the United States healthcare and its workforce. Orthopaedic and neurosurgery residents and fellows, as part of this workforce have also experienced some of the uncertainty and stress caused by this pandemic. Concerns exist regarding the effects of the pandemic on spine surgery education due to the cancellation of all elective surgeries.
