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 study utilizes a biomechanical model of the thumb to estimate the force produced at the thumb-tip by each of the four extrinsic muscles. We used the principle of virtual work to relate joint torques produced by a given muscle force to the resulting endpoint force and compared the results to two separate cadaveric studies. When we calculated thumb-tip forces using the muscle forces and thum...

Scalar implicature depends on the activation of alternatives. For instance, in English, finger implicates 'not thumb', suggesting that thumb is an activated alternative. Is this because it more specific (Quantity) and equally short (Manner)? Indeed, toe doesn't imply big toe', perhaps toe is longer. As L. Horn points out, Quantity/Manner explanation predicts if English had simplex Lati...

preaxial polydactyly is the most common duplication pattern in white and asian populations (1). it is a congenital anomaly with a wide range of manifestations .current classification do not have the capacity to classify all different types of radial polydactyly. we describe here a very rare and unusual case of bilateral preaxial polydactyly (triplication) in a woman and report the operations re...
