Fractures of the head of the radius with displacement are relatively uncommon in children. During six years, 450 cases of fracture of the radial head have been treated at the Birmingham Accident Hospital. Of these eighty were in patients under the age of eighteen years ; but when cases of fissure fracture and greenstick fracture with minimal deformity were excluded (together with one or two cas...

OBJECTIVES To examine vestibular control of balance in those who recovered the ability to stand after middle cerebral artery (MCA) stroke. METHODS Sixteen patients with MCA stroke were compared with 10 age matched controls. Two additional patients were studied with isolated corticospinal tract lesions, one each at the level of the pons and medulla. Vestibular evoked postural responses were ob...

abstract for seismic design, it is important to estimate the, maximum lateral displacement (inelastic displacement) of the structures due to earthquakes for several reasons. seismic design provisions estimate the maximum roof and storey drifts occurring in major earthquakes by amplifying the roof displacement and drifts of the structures obtained by elastic analysis subjected to seismic design ...

A horizontally moving target was followed by rotation of the eyes alone or by a lateral movement of the head. These movements resulted in the retinal displacement of a vertically moving target from its perceived path, the amplitude of which was determined by the phase and amplitude of the object motion and of the eye or head movements. In two experiments, we tested the prediction from our model...

Untreated 3- and 4-part fractures of the proximal humerus have a poor functional outcome. Open operation increases the risk of avascular necrosis and percutaneous reduction and fixation may be preferable. We report 27 patients, 9 with 3-part and 18 with 4-part fractures, treated by percutaneous reduction and screw fixation. Thirteen of the 4-part fractures were of the valgus type with no signif...

BACKGROUND Traumatic Brain Injury (TBI) is the leading cause of death in all age group. The incidence of CSI increases with the severity of TBI so prompt care of cervical spine is necessary in all patients with moderate to severe head injury. The objective of this study was to determine the frequency of cervical injury in patients with moderate to severe head injury and different types of traum...

The importance of head injuries to restrained far seat occupants has been previously documented. Control of the kinematics leading to these injuries can likely be achieved by improved torso lateral restraint. In adults, seat belt pre-tensioning reduced lateral head displacement by approximately 200 mm in far-side impacts. Children, however, may demonstrate greater lateral movement as previous s...

an enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. at first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. the advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...

In the present work, the mathematical model of a homogeneous, isotropic thermoelastic double porous micro-beam, based on the Euler-Bernoulli theory is developed in the context of Lord-Shulman [1] theory of thermoelasticity. Laplace transform technique has been used to obtain the expressions for lateral deflection, axial stress, axial displacement, volume fraction field and temperature distribut...

The aim of our study was to find symptomatic diagnostic factors for sideways displacement of the temporomandibular joint disc, compared with anterior or rotational disc displacement. A consecutive series of 2310 temporomandibular joints were examined with MRI to define the clinical signs and symptoms particularly related to sideways disc displacement compared to anterior disc displacement with ...
