BACKGROUND Clinical results of percutaneous needle fasciotomy (PNF) in Japanese patients with Dupuytren's disease are reported. METHODS In this prospective study, 51 patients (103 fingers: 1 index, 9 middle, 47 ring, and 46 small) underwent PNF at 99 metacarpophalangeal (MCP) and 68 proximal interphalangeal (PIP) joints. Patients were assessed postoperatively after 1 day, at 1, 2, 4, 6, and 8...

BACKGROUND To study the reliability and validity of high-resolution peripheral quantitative CT (HR-pQCT) with microCT (μCT) as gold standard in the visual detection of cortical breaks in metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. METHODS Ten cadaveric fingers (10 MCP and 9 PIP joints) were imaged by HR-pQCT and μCT and visually analyzed by two independent readers. In...

The purpose of this work is to develop a 3D inverse dynamic model of the human finger for estimating the muscular forces involved during free finger movements. A review of the existing 3D models of the fingers is presented, and an alternative one is proposed. The validity of the model has been proved by means of two simulations: free flexion-extension motion of all joints, and free metacarpopha...

There are different biometric modalities used to identify person which includes palmprint, face, fingerprint, iris and hand geometry. Apart from these biometric modalities, finger knuckle print also used as one of the cost effective biometric identifier. Finger knuckle print is defined by the back side of fingers. On the back side of fingers there are three joints named as Metacarpophalangeal (...

CMAJ 2000;162(13):1833-8 The case Three months after an uncomplicated pregnancy and delivery Mrs. D consults her physician about new pain and swelling in her wrists and several proximal interphalangeal joints; 1 wrist is swollen and tender and there is tenderness in the ring metacarpalphalangeal (MCP) and 2 proximal interphalangeal (PIP) joints of each hand. She has morning stiffness which last...

The present study aimed at assessing impacts of daily piano practice on kinematics and muscular activity of finger movements while musicallynaïve individuals played the piano. Six participants were asked to play a certain melody with metronome with the non-dominant left hand. They practiced fifty trials per day over four successive days. Time-varying joint positions at the hand were recorded us...

The classic appearance of the rheumatoid hand with swollen and often dislocated metacarpophalangeal (MCP) joints, atrophic intrinsic muscle compartments, ulnar deviating fingers, and variously hyperextended or flexed and swollen interphalangeal joints is easily recognized. The explanation of the mechanisms involved in the pathogenesis of the intrinsic muscle atrophy (exclusive of the atrophy of...

Monocyte influx and activation in synovial joints are important in the pathogenesis of both degenerative and inflammatory arthropathies. In this study, we demonstrate the potential of articular cartilage to directly modulate these events. IL-1-stimulated human articular chondrocytes transcribed 0.7-kb monocyte chemoattractant protein-1 (MCP-1) mRNA. In situ hybridization of cartilage organ cult...

Objective The objective of this study was to describe the initial stage of a generalized theory of high-velocity, low-amplitude thrust (HVLAT) techniques for joint manipulation. Methods This study examined the movements described by authors from the fields of osteopathy, chiropractic, and physical therapy to produce joint cavitation in both the metacarpophalangeal (MCP) joint and the cervical...

OBJECTIVES To develop and test the reliability of a modified version of the OMERACT rheumatoid arthritis magnetic resonance imaging score (RAMRIS) for erosions using extremity MRI (eMRI) with reduced field of view (RAMRIS-RV). METHODS Using a MagneVu 0.2 T machine, the preliminary RAMRIS-RV assessed erosions in metacarpophalangeal (MCP) joints 2-3, bases of metacarpal (MC) 2-5, and all wrist ...
