Silicone and Pyrocarbon Artificial Finger Joints [PDF]

Applied Bionics and Biomechanics, 2021
Artificial finger joint design has been developed through different stages through the past. PIP (proximal interphalangeal) and MCP (metacarpophalangeal) artificial finger joints have come to replace the amputation and arthrodesis options; although ...

Flexion Angles of Finger Joints in Two-Finger Tip Pinching Using 3D Bone Models Constructed from X-Ray Computed Tomography (CT) Images [PDF]

Applied Bionics and Biomechanics, 2020
The motion analysis of two-finger tip pinching using the thumb and index finger provides crucial data for designing the motion mechanism of electric prosthetic hands. The purpose of this study is to determine the joints that have high mobility during two-

Mapping the bare area and transcortical pores in finger joints: co-location with bone erosions in rheumatoid arthritis [PDF]

RMD Open
Objective Transcortical pores and the bare area have been suggested as structural determinants of bone erosions in rheumatoid arthritis (RA). We aimed to map the spatial distribution of transcortical pores and bare areas in whole finger joints of ...

Dorsal Finger Fold Recognition by Convolutional Neural Networks for the Detection and Monitoring of Joint Swelling in Patients with Rheumatoid Arthritis

Digital Biomarkers, 2022
Digital biomarkers such as wearables are of increasing interest in monitoring rheumatic diseases, but they usually lack disease specificity. In this study, we apply convolutional neural networks (CNN) to real-world hand photographs in order to ...

Concomitant Dislocation of Proximal and Distal Interphalangeal Joints of Small Finger: A Case Report [PDF]

Journal of Kerman University of Medical Sciences, 2021
A 24 old man sustained an injury to his right hand when playing soccer as goalkeeper, most probably from a direct strike for the ball or offender foot. On physical examination the injury was limited to the right middle finger, which was swollen, tender ...

Peri-Prosthetic Joint Infection after Finger Joint Arthroplasty [PDF]

Surgical Infections, 2020
Background: Endoprosthetic treatment of finger joints is an established procedure. However, data on peri-prosthetic finger joint infections (PJI) are rare. The goal of this retrospective study was to assess infection rates and treatment outcomes after PJI of the finger joints.

Development and Evaluation of an Adaptive Multi-DOF Finger with Mechanical-Sensor Integrated for Prosthetic Hand

Micromachines, 2020
To realize the adaptive grasping of objects with diverse shapes and to capture the joint angles of the finger, a multi degree of freedom (DOF) adaptive finger for prosthetic hand is proposed in this paper. The fingers are designed with three joints.

Wearable Multifunctional Additive Hand System for Enhancing the Workspace and Grasping Capability of the Human Hand

IEEE Access, 2022
In this study, a wearable multifunctional additive hand (MAH) system is proposed for enhancing the workspace and grasping capability of the human hand. The MAH system consists of a main body and three fingers, and each finger has two joints.

Bio-Inspired Tendon-Driven Finger Design With Isomorphic Ligamentous Joint

IEEE Access, 2020
This paper suggests a novel type of bio-inspired finger design in that the joints that compose the finger mimic the features of human finger joints. They have isomorphic structures but different movements, further, there is no friction between bones in ...
