The importance of the thumb can be gauged from ancient Indian mythology where it is mentioned in the Mahabharatha. Drona poignantly demands the thumb as a gift for his gurudakshina from Ekalavya. As mentioned by Napier, the absence of the thumb, whether congenital or post-traumatic, significantly impairs hand function. Although technical advances have led to changes in surgical methods, the gen...

Primary sarcomas of the thumb metacarpal are rare malignant lesions. Surgical treatment involves amputation versus tumor resection with thumb reconstruction. If complete tumor resection is possible, thumb preservation may be considered, as the thumb is vital to hand function. Following tumor resection, previous reports have described graft reconstruction with fusion to the trapezium or scaphoid...

There is currently an increase in the media attention given to yachting harbour management. Some of these harbours have existed since the 1960s and yet, it is only recently that problems have arisen between public and private partners. This paper presents the case of leisure harbours and designs an initial model of their governance issues. An empirical analysis of a single case shows that the u...

Thumb opposition is essential for grasping, and involves the flexion abduction of carpometacarpal metacarpophalangeal joints thumb. The high number degrees freedom thumb in a fairly small space makes vivo recording its kinematics challenging task. For this reason, along with very limited independence movement joint, many devices do not implement sensors to measure such movement, which may lead ...

maternal hyperglycemia during early gestation is associated with an increased incidence of congenital anomalies. a case of mater­nal diabetes syndrome is presented here with a rare constellation of congenital anomalies, i.e., bifurcated distal pha­lanx of the thumb, patent ductus arteriosus and cleft lip.

BACKGROUND AND AIM: Thumb sucking has been reported as one of the etiologic factors for malocclusion. The aim of this study was to determine the prevalence of thumb sucking and use of different kinds of habit breaker (HB) appliances in children attending private kindergartens in Kerman, Iran.METHODS: The census method was used in the present cross-sectional study, and the study population consi...

The aim of this study was to determine in monkeys if inactivation of dentate and lateral interposed deep cerebellar nuclei preferentially impairs certain movements relative to others. Constrained movements of the digits were trained with digits, hand, and elbow constrained in a cast. Simple movements were flexion of Thumb or Index. A compound movement was simultaneous flexion of Thumb+Index. An...

A case of mallet thumb, with a closed rupture of the extensor pollicis longus at its distal insertion, is presented. Conservative treatment resulted in a near normal function.

This paper proposes a flexible and wearable hand exoskeleton which can be used as a computer mouse. The hand exoskeleton is developed based on a new concept of wearable mouse. The wearable mouse, which consists of flexible bend sensor, accelerometer and bluetooth, is designed for comfortable and supple usage. To demonstrate the effectiveness of the proposed wearable mouse, experiments are carri...

An exoskeleton was designed with the primary goal of enhancing the maximum dynamic capability of a human, thus allowing the user to run faster, jump higher, or traverse challenging terrain. This paper presents the mechanical design of an alpha prototype with a focus on increasing the maximum vertical jump height of a human. High torque motors were constrained to the body with two degrees of fre...
