This article reports a systematic research effort aimed at establishing a normative database of thumb circumduction range of motion (ROM) and related kinematic characteristics in vivo while examining the effects of anthropometry, gender, and direction of rotation. Twenty-eight (14 men, 14 women) anthropometrically diverse participants performed maximum voluntary thumb circumductions as the traj...

The condition of chronic instability of the MP (metacarpophalangeal) joint of the thumb, may be the resultant of chronic strain of the ulnar collateral ligament of the MP joint. This condition was described in Scottish gamekeepers who used to kill hunted animals by a special manoeuvre subjecting the thumb to extension abduction force, and was termed "Gamekeeper's Thumb" (Campbell, 1955). Nowada...

Background: The function of the thumb is critical to overall hand function. Uniquely endowed with anatomic features that allow circumduction and opposition, the thumb enables activities of pinch, grasp, and fine manipulation that are essential in daily life. Destruction of the thumb secondary to trauma represents a much more significant loss than would result from loss of any other digit. There...

Introduction: Trigger Thumb is a condition that caused by thickened A-1 pulley, often secondary to stenosed tendon sheath. There are several treatment options for trigger thumb, yet the use of prolotherapy treat has not been widely discussed in literature. Therefore, this study aims present case Bilateral Thumbs which were treated using Prolotherapy.
 Case: A 49-year-old female patient was...

duplication of inferior vena cava (ivc) is a rare fi nding in radiologic studies and its coincidence with thrombosis is even rarer. here we described a rare case with duplication of ivc and symptomatic venous thrombosis of her lower extrimity.

BACKGROUND Injury to the ulnar collateral ligament (UCL) of the first metacarpophalangeal joint (MCPJ) is a common injury, especially in skiers. It is often misdiagnosed, which can lead to chronic instability. OBJECTIVE This article reviews the current literature on UCL injury of the thumb and describes the clinical assessment and management. DISCUSSION The UCL of the thumb is often injured...

Fanconi anemia (FA) is a genetic disease resulting in bone marrow failure, high cancer risks, and infertility, and developmental anomalies including microphthalmia, microcephaly, hypoplastic radius and thumb. Here we present cDNA sequences, genetic mapping, and genomic analyses for the four previously undescribed zebrafish FA genes (fanci, fancj, fancm, and fancn), and show that they reverted t...

PURPOSE Idiopathic osteoarthritis (OA) of the thumb carpometacarpal (CMC) joint is a common disabling disease that often causes pain and motion loss. The aims of this study were to characterize the multidimensional motion capability of the thumb CMC joint in a group with severe CMC OA and to compare it with a control group. METHODS We included 15 subjects with stage III/IV CMC OA according to...
