Are the Umbilicus and Iliac Crests Truly at the Level of L4 to L5? A Computed Tomography-Based Study of Surface Anatomy of the Anterior Lumbar Spine.

Background: This study aimed to determine whether the iliac crests are truly at the level of L4 to L5, accounting for patient demographic and anthropometric characteristics.

Methods: We measured the umbilicus and iliac crests relative to the lumbar spine using computed tomography of patients without spinal pathology, accounting for the influences of patient height, weight, body mass index (BMI), sex, race, and ethnicity.

Results: A total of 834 patients (391 men and 443 women) were reviewed.

Nonoperative Management of Both Column Acetabular Fracture and Protrusio Acetabuli in a Pregnant Patient: A Case Report.

Case: We present a case of a 39-year-old woman at 23 weeks gestation who sustained traumatic both-column acetabular fracture and protrusio acetabuli, managed with initial traction and delayed total hip arthroplasty (THA) until after cesarean section delivery.

Conclusion: Initial skeletal traction with subsequent delayed THA may be a viable treatment option in select pregnant female patients who sustain both-column acetabular fractures. Interdisciplinary collaboration is necessary to optimize maternal-fetal health and provide patient education of procedural risk to enable informed decision making.

Evolving Effects of the COVID-19 Pandemic on Hip Fracture Outcomes: A Retrospective Comparison of Pre, Early, and Late Pandemic Timepoints.

Introduction: Hospital systems were strained during the COVID-19 pandemic, and although previous studies have shown that surgical outcomes in healthy hip fracture patients were unaffected in the initial months of the pandemic, subsequent data are limited. This study examined the evolution of hip fracture care throughout the COVID-19 pandemic.

Methods: A retrospective review (level III evidence) was done of surgically treated adult hip fractures at a Level 1 academic trauma center from January 2019 to September 2022, stratified into three groups: pre, early, and late pandemic.

Morphometric analysis of cervical neuroforaminal dimensions from C2-T1 using computed tomography of 1,000 patients.

Background: Race and sex differences are not consistently reported in the literature. Fundamentally, anatomical differences of cervical neuroforaminal dimensions (CNFD) amongst these groups would be important to know.

Purpose: To establish normative radiographic morphometric measurements of CNFD and uncover the influence of patient sex, race, and ethnicity while also considering anthropometric characteristics.

Evaluating the Presence of Disgust in Animals.

The emotion of disgust in humans is widely considered to represent a continuation of the disease-avoidance behavior ubiquitous in animals. The extent to which analogs of human disgust are evident in nonhuman animals, however, remains unclear. The scant research explicitly investigating disgust in animals has predominantly focused on great apes and suggests that disgust might be present in a highly muted form.
