BACKGROUND Vertebrobasilar dolichoectasia (VBD) is characterized by abnormal dilation, distortion, and extension of the vertebral artery (VA) and basilar artery (BA). This study investigated whether BA and VA morphological characteristics were factors predicting VBD. MATERIAL AND METHODS Individuals aged ≥18 years undergoing contrast-enhanced magnetic resonance angiography (CE-MRA) of the head/...

Background. Residual dysplasia occurs in some hip joints with DDH treated conservatively. This may lead to osteoarthrosis in relatively near future. Our study aimed to determine which radiographic parameters and clinical factors could reliably predict hip joint development after closed reduction. Material and methods. We examined 81 patients and 107 hip joints treated with over-head traction. T...

Intrathoracic displacement of the humeral head is a very uncommon condition and can be life threatening due to lungor heart injuries. There is a report of this condition where intrathoracic bone fragment was missed. Because of rareincidence there is no guideline for approach and treatment of this condition.We hereby present a case of intrathoracic displacement of fractured hum...

Chronic posterolateral rotatory instability (PLRI) is the most common form of chronic elbow instability.PLRI usually occurs from a fall on the outstretched hand. On impact, the radial head and ulna rotate externally coupled with valgus displacement of the forearm. This leads to posterior displacement of the radial head relative to the capitellum, thus causing disruption of some or all of the la...

BACKGROUND Primary total hip arthroplasty leads to better functional capacities but a general weakness of abductor muscles often persists. A larger head component may improve the postural balance in the medial-lateral direction. The aims of this study are (1) to compare postural stability in patients after total hip and surface replacement arthroplasties and (2) to evaluate the effect of the bi...

braced frames structures have a good lateral stiffness against earthquakes. however, energy loss of their members is slight and strong forces are given to the structures. moment frames have a more flexible function against earthquakes and also have a better flexibility than braced frames. however, since its lateral stiffness is low, too much displacement of the structure results in an increase ...

When the head is unrestrained, the large amplitude gaze shifts are composed of coordinated eye and head movements. The position of the eyes at the onset of the gaze shift can alter the eye and head contributions to the movement. The movements of the eyes and head during the unrestrained-head gaze shift follow well-defined relationships. It is possible to predict the displacement of the eye and ...

The aim of the study was to introduce a new method for measuring the residual displacement of the femoral head after internal fixation and explore the relationship between residual displacement and osteonecrosis with femoral head, and to evaluate the risk factors associated with osteonecrosis of the femoral head in patients with femoral neck fractures treated by closed reduction and percutaneou...

ABSTRACT Luxation of the temporomandibular joint (TMJ) in horses, despite being an uncommon condition, is often associated with local trauma involving head. Its clinical importance mainly related to painful injury and impairment multiple movements involved chewing breaking foods. The objective current work describe manual reduction technique TMJ dislocation a 6-year-old Mangalarga Marchador sta...
