Incidence of and Risk Factors for Reoperation and Revision Following Total Elbow Arthroplasty with an Anatomic Convertible Prosthesis.

Background: Total elbow arthroplasty (TEA) remains a valuable tool for treating inflammatory, degenerative, and traumatic elbow conditions. This study aimed to understand the incidence of and risk factors for reoperation following TEA at a high-volume center utilizing an implant with a convertible linkage and the potential for anatomic lateral column reconstruction.

Methods: All patients undergoing primary TEA with the Latitude prosthesis (Stryker) from July 2001 to May 2020 were identified.

Disturbance alters transience but nutrients determine equilibria during grassland succession with multiple global change drivers.

Disturbance and environmental change may cause communities to converge on a steady state, diverge towards multiple alternative states or remain in long-term transience. Yet, empirical investigations of successional trajectories are rare, especially in systems experiencing multiple concurrent anthropogenic drivers of change. We examined succession in old field grassland communities subjected to disturbance and nitrogen fertilization using data from a long-term (22-year) experiment.

Supination Adduction Vertical Medial Malleolar Fracture Fixation with Buttress Plating vs a Novel Screw-Only Construct: A Cadaveric Biomechanical Study.

Background: Supination adduction ankle fractures are unique among rotational ankle fractures as plate constructs are more commonly used than independent screws for medial malleolar fixation. The purpose of this study was to compare fracture displacement between plate fixation to a novel screw-only construct using a cadaveric biomechanical early-weightbearing model for the treatment of vertical medial malleolus fractures.

Methods: Six nonosteoporotic fresh-frozen cadaver shanks and feet in matched pairs underwent a vertical osteotomy of the medial malleolus to simulate the supination adduction type injury.

Understanding the challenges faced by Michigan's family farmers: race/ethnicity and the impacts of a pandemic.

Michigan is a critical agricultural state, and small family farms are a crucial component of the state's food sector. This paper examines how the race/ethnicity of the family farm owners/operators is related to farm characteristics, financing, and impacts of the pandemic. It compares 75 farms owned/operated solely by Whites and 15 with People of Color owners/operators.

Sage Insights Into the Phylogeny of : Dealing With Sources of Discordance Within and Across Genomes.

Next-generation sequencing technologies have facilitated new phylogenomic approaches to help clarify previously intractable relationships while simultaneously highlighting the pervasive nature of incongruence within and among genomes that can complicate definitive taxonomic conclusions. L., with ∼1,000 species, makes up nearly 15% of the species diversity in the mint family and has attracted great interest from biologists across subdisciplines.
