Background: The pathophysiology of enthesopathy and tendinopathy is mucoid degeneration, which includes chondroid metaplasia. The chondroid metaplasia can be associated with calcification. Inflammation is typically absent unless calcification triggers a self-limited immune response representing acute calcific tendinitis.

- The study focuses on identifying risk factors for subtalar fusion (STF) after open reduction internal fixation (ORIF) of calcaneal fractures, finding that certain demographics and medical issues can influence outcomes.
- Both alcohol and drug abuse, depression, obesity, and tobacco use are associated with an increased likelihood of undergoing STF within five years following surgery.
- The analysis utilized a national claims database over nearly 12 years, revealing no significant differences in reimbursement rates or basic demographics between patients who required STF and those who did not.
Introduction: Lumbar disk arthroplasty (LDA) is a relatively novel procedure with limited indications and use in the United States, especially relative to lumbar fusion (LF). This study aimed to determine surgical trends between LDA versus LF over the past 10 years to quantify absolute/relative surgical volume over time and compare baseline patient demographics, readmission, 2-year revision rates, and costs-of-care.
Methods: A total of 714,268 patients were identified from a nationwide database who underwent LF (n = 710,527) or LDA (n = 3,741) from 2010 to 2021.
Study Design: Retrospective study.
Objective: The purpose of this study was to determine whether IBD in patients with degenerative lumbar changes undergoing primary 1-2LF is associated with higher rates of (1) in-hospital length of stay, (2) medical complications, (3) readmissions, and (4) costs of care.
Summary Of Background Data: In the United States, the prevalence of inflammatory bowel disease (IBD) has increased concurrently with an aging population with degenerative disk changes.
Understanding how one brain region exerts influence over another in vivo is profoundly constrained by models used to infer or predict directed connectivity. Although such neural interactions rely on the anatomy of the brain, it remains unclear whether, at the macroscale, structural (or anatomical) connectivity provides useful constraints on models of directed connectivity. Here, we review the current state of research on this question, highlighting a key distinction between inference-based effective connectivity and prediction-based directed functional connectivity.
