Tempered Fractional Trapezium Inequalities

Axioms, 2022
The main objective of this paper is to derive some new fractional analogs of trapezium-like inequalities essentially using the class of preinvex functions and the concepts of tempered fractional integrals. We discuss some special cases that show that our

Complete dislocation of the trapezium

Acta Orthopaedica et Traumatologica Turcica, 2021
Complete dislocation of the trapezium is a very rare injury. Various treatment modalities have been suggested in the literature. In this study, we are presenting a complete dislocation of the trapezium treated by open reduction and Kirschner wire ...

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus. [PDF]

J Anat
Knuckle walking is one hypothesized behavior of the Pan‐Homo last common ancestor. We analyzed carpal morphology, including Euclidean distances between behavioral pairs, to investigate whether the carpals of knuckle‐walking taxa appear relatively specialized.

Finite element analysis to clarify stress on articular surface of thumb carpometacarpal joint in static loading conditions by using CT images

Journal of Biomechanical Science and Engineering, 2023
Analyzing the biomechanics of the thumb carpometacarpal (CMC) joint is essential for elucidating the etiology of osteoarthritis (OA) and for developing a mechanics-based treatment.

Morphological integration and shape covariation between the trapezium and first metacarpal among extant hominids [PDF]

, 2023
Objectives: The shape of the trapezium and first metacarpal (Mc1) markedly influence thumb mobility, strength, and the manual abilities of extant hominids. Previous research has typically focused solely on trapezium-Mc1 joint shape.

Influence of differences in bone morphology on the distribution patterns of subchondral bone density across the trapeziometacarpal joint

Scientific Reports, 2022
We aimed to clarify the effects of morphological patterns of the trapezium and first metacarpal on the distribution of subchondral bone density across the articular surface of the trapeziometacarpal (TMC) joint using computed tomography ...
