Background: The acromion clavicular joint dislocations are common injuries of the shoulder. The severity is dependentupon the degree of ligamentous injury. Surgical treatment is typically performed in higher grade acromioclavicularseparation with several static and dynamic operative procedures with or without primary ligament replacement.Methods: 47 patients with acute Rockwood type III, IV, an...

fracture mapping of late permian-early triassic flat-lying sedimentary rocks in the sydney basin,new south wales, australia, shows that joints developed originally in extension were faulted in subsequentevents. joints with a regional distribution fall into two (early and late) formed groups. group i joints propagatedhorizontally and never interfered with each other. these joints were subsequent...

the rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. for noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. in this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, generaliz...

aim: abnormal joint mobility is an important factor in movement dysfunction and physical disability. a general lack of descriptive details exists for measurements of hip rotation range of motion (rom). this study was designed to establish the influence of hip position on active and passive range of motion of the hip in external and internal rotation(ext & int rot). material & methods: ...

in this research, the influence of bolt preload on the fatigue strength of 2024-t3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. to do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 n-m and then fatigue tests were conducted under various cyclic axial load levels. in the numerical method, th...

abstract   background: sacroiliac joint (sij) dysfunction is a widely known but poorly defined   cause of low back pain. to our knowledge, few published studies have been   conducted to evaluate systematically the prevalence and significance of concomitant   sacroiliac joint dysfunction in patients with herniated lumbar discs. as concomitant   sij dysfunction in low back pain patients is likely...

objectives: joint attention is one of the most important prerequisite of language and social development. there are two types of joint attention, initiating joint attention and responding to joint attention. this study examined the development of responding to joint attention in typically developing children in 8-30 month. methods: this study was cross-sectional. 61 children (40 female and 20 m...
