Abstract Current sheets are ubiquitous plasma structures that play the crucial role of being energy sources for various magnetic phenomena. Although a plethora current sheet equilibrium solutions have been found, collisionless process through which disequilibrated relaxes or equilibrates remains largely unknown. Here we show, analyses phase-space distributions single-particle orbit classes and ...

BACKGROUND Lymph node dissection in Rouviere's sulcus (RS) is essential during left-sided hepatectomy and caudate lobectomy for hilar cholangiocarcinoma. However, the small segmental or subsegmental arteries (SA/SSA) are often encountered in RS and must be preserved to prevent critical complications, such as liver infarction or liver failure. The aim of this study is to elucidate the anatomy of...

Congenital duplication of the thumb is usually reconstructed by 18 months of age. This paper reports satisfactory outcome following reconstruction of two Wassel Type IV duplicate thumbs in adults aged over 40. Both achieved a good outcome based on Tada's criteria and a subjective Visual analogue score 8.

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...

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...

With lumbar epidural anaesthesia, big toe skin temperature increases and is associated with a compensatory decrease of thumb temperature. The purpose of the present study was to examine whether thumb-big toe temperature differences were affected by age. Following the attachment of temperature probes at the digital pad of the right big toe and the right thumb, lumbar epidural anaesthesia at L2/3...

The use of the abductor digiti minimi transfer to restore opposition in patients with hypoplasia of the thumb has been widely described in the literature. It has been found to be effective in restoring abduction, but less so in restoring the rotational component of opposition. In cases where there is concomitant supination of the thumb, abductor digiti minimi transfer alone would not result in ...

Gamekeeper’s thumb is used to describe an acut or chronic injury to Ulnar Collateral Ligament (UCL) of thumb. We present the Magnetic Rezonance İmaging (MRI) findings of a rare case with gamekeeper’s thumb. MRI allows optimal detection and evaluation of most soft-tissue and bone lesions in the traumatic finger, including injuries the collateral ligaments.

The effects of cannulation of the radial artery were studied in 23 patients. Distal arterial pressure on the thumb, measured during radial or ulnar artery compression, was compared with the result of a modified Allen test performed before operation. Distal arterial pressure on the thumb was monitored for approximately 10 days after removal of the cannula. It was found that radial artery thrombo...
