anatomical vascular variations are rare causes of carpal tunnel syndrome. an aberrant medial artery is the most common vascular variation, while an aberrant radial artery causing carpal tunnel syndrome is even more rare, with an incidence ranging less than 3%. this article reports a patient with compression of the median nerve at the carpal tunnel by an aberrant superficial branch of the radial...

background: stroke is the first cause of morbidity all around the world. entrapment neuropathies are a known complication of stroke. the objective of this study is to assess the frequency of subclinical carpal tunnel syndrome in the healthy and paretic hands of stroke patients. methods: the authors performed nerve conduction study in the first three days after admission in 39 stroke patients wi...

Tunnelling in urban areas is growing response to efficient transportation, many tunnels are constructed soft ground at shallow depths. Urban usually as twin-parallel and their adjacent constructions may cause settlements that distort damage the existing structures utilities above tunnel. In past few decades, tunnel boring machines have been used drill increasingly difficult geotechnical conditi...

Aiming at the safety of tunnel operation, based on investigation and statistical analysis a large number operating diseases, comprehensively considering interaction between surrounding rock structure, this paper establishes failure criteria for rocks lining materials by using numerical limit theoretical methods, analyzes overall stability instability mechanism shallow under unsymmetrical pressu...
