The main study objective was to determine if experienced emergency physicians can accurately identify a subgroup of patients with anterior shoulder dislocation for whom prereduction radiographs do not alter patient management. Our prospective study evaluated 97 patients who presented to 2 ski-hill clinics and to our rural emergency department with possible shoulder dislocation between November ...
Temporomandibular joint (TMJ) dislocation has not previously been reported as a complication of beta-blocker toxicity. We are reporting two cases of TMJ dislocation resulted from acute severe intoxication with pure propranolol (PPL) for the first time. Bilateral TMJ dislocation happened in two patients who were admitted to intensive care unit with diagnosis of severe acute PPL toxicity. Clinica...
Dutch uses a variety of strategies to dislocate (or seemingly dislocate) elements from the main proposition. Next to potentially sentence-internal dislocations such as appositions and parentheses, the following types of peripheral dislocation exist: contrastive left-dislocation (CLD), hanging topic left-dislocation (HTLD), backgrounding right-dislocation (BRD), and afterthoughts (AFT); these ar...
We have studied fracture-dislocation of the fifth lumbar vertebra in seven patients and reviewed 50 previously reported cases. Based on this information, we have classified the injury into five types: type 1, unilateral lumbosacral facet-dislocation with or without facet fracture; type 2, bilateral lumbosacral facet-dislocation with or without facet fracture; type 3, unilateral lumbosacral face...
A (microscopic) static elastoplastic field theory of dislocations with moment and force stresses is considered. The relationship between the moment stress and the Nye tensor is used for the dislocation Lagrangian. We discuss the stress field of an infinitely long screw dislocation in a cylinder, a dipole of screw dislocations and a coaxial screw dislocation in a finite cylinder. The stress fiel...
Anterior hip dislocation is much less frequent when compared with posterior dislocation of the hip joint, with open dislocation being still rarer. We report a case of an open anterior hip dislocation in a 23-year-old male who presented to us in the emergency department, and also present a review of the literature.
The authors report four cases of inferior dislocation of the proximal tibiofibular joint. A literature search disclosed reports on superior, anterolateral and posterolateral dislocation, but none on inferior dislocation of the proximal tibiofibular joint. The latter was associated in these four cases with fracture of the tibia, as also noted in cases of superior dislocation, and with severe neu...
Traumatic dislocation of the hip or knee can occur after high-energy trauma and is often associated with concomitant injuries and secondary complications. Concomitant traumatic dislocation of both hip and knee is rare. We describe a case of combined ipsilateral posterior hip dislocation with a posterior acetabular fracture and a complete open knee dislocation with disruption of the popliteal ar...
this case is a 19-year-old soldier who suffered a combined elbow dislocation and posterior monteggia fracture and dislocation (type ii). the ulna fracture was managed by orif. the elbow dislocation was managed by closed reduction and immobilization in 900 flexion. the posteriorly dislocated radial head was kept reduced by a transarticular pin. after 6 months elbow and forearm motion was restric...
Equal channel angular rolling (ECAR) is a severe plastic deformation (SPD) technique which has been used to produce metal sheets with ultra-fine grain structure. In the present work, the relationships between the mechanical properties and microstructure of samples during the ECAR process have been investigated. The Rietveld method was applied to analyze the X-ray diffraction pattern and to det...
