A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves. Dislocations can occur in any joint major (shoulder, knees, etc.) or minor (toes, fingers, etc.). The most common joint dislocation is a shoulder dislocation. Treatment for joint dislocation is usually by closed reduction, that is, skilled manipulation to return the bones to their normal position. Reduction should be done only by trained people, because it can cause injury to soft tissue around the dislocation. The following symptoms are common with any type of dislocation. Intense pain Joint instability Deformity of the joint area Reduced muscle strength Bruising or redness of joint area Difficulty moving joint Stiffness Joint ...

Radial head dislocation occurs when the radial head is displaced from its normal articulation with the ulna and the humerus. The dislocation may be acquired or congenital (see the separate article on congenital radial head dislocation). Addition...
The authors report 2 cases of isolated traumatic anterior dislocation of the radial head in children. In the first case, with an acute dislocation, closed reduction followed by plaster cast immobilisation for one month gave a good result. In the second case, the dislocation was also traumatic in origin but had remained unreduced for 5 years. Arthrography of the elbow showed the head to be intracapsular. The authors believe that a neocapsule forms in cases of old unreduced dislocation and arthrography is therefore of little help to differentiate a long standing traumatic dislocation from a congenital dislocation. Based on their experience and on the literature, the authors propose closed reduction followed by immobilisation as a treatment for acute dislocation; old unreduced dislocations cannot be reduced by manipulation and with the exception of very symptomatic cases, the authors prefer to avoid open reduction, which carries a risk of joint stiffness ...
Introduction: Vascular injury associated with closed posterior elbow dislocations is rare and it usually occurs along with open dislocation, anterior dislocation, penetrating injuries, dislocations associated with fracture. We report such a case of We report such a case of closed posterior elbow dislocation with complete brachial artery rupture. Case Report: A 58 year old lady sustained a posterior dislocation of right elbow following a fall at home. She presented three days later with complaints of severe pain, swelling around the right elbow and numbness of fingers following a closed reduction done elsewhere. Compute Tomography Computed tomography-angiography showed complete transection of brachial artery. Patient was treated with thrombectomy, right great saphenous vein interposition repair of brachial artery and forearm fasciotomy. Conclusion: Posterior dislocation of elbow with vascular injury, though a rare condition, early diagnosis and treatment of the vascular injury is the key to prevent

Glissile junctions: Insights from discrete dislocation dynamics and development of a continuum model. Markus Stricker. Karlsruhe Institute of Technology. The understanding of the mechanisms governing plastic deformation of metals is the understanding of dislocation motion from single dislocations to collective behavior. At first the method of Discrete Dislocation Dynamics is reviewed with an example of irreversible dislocation motion in cyclic loading due to strain gradients. Subsequently, the method is used to show that glissile junctions are an active dislocation source mechanism, contributing not only significantly to the dislocation density, but also to the macroscopic plastic strain. This discovery is then coarse-grained into a dislocation density rate formulation and implemented in a continuum theory within the framework DAMASK. The results show that it is possible to populate initially dislocation density free glide systems. With the proposed extension, the continuum model is able to ...
The risk factors for revision surgery are slightly different to those of primary surgery, with soft tissue dissection being far greater. However, many factors contribute to this heightened risk.. It is well known that age is a contributory factor to dislocation 10. Morrey et al. showed that THA in patients older than 80 years had a twofold to threefold increase in the rate of dislocation compared with younger patients, and it is no surprise that revision patients are older on average than primary THA patients. More significantly, the number of previous operations also increases the risk 11. So it may be logical that revisions carry an increased risk of dislocation, especially when approaching the second or third revision.. The other important preoperative factor affecting the risk of dislocation is the indication for revision, with often more than one indication present. Patients who have revisions for recurrent dislocation are inherently at risk of suffering from further dislocations, with some ...

Dislocation of the shoulder typically occurs from falling onto an outstretched arm or a blow to the side or back of the shoulder when falling on it. This can happen in different sports activities or falls. Dislocations are managed medically to relocate the head of the humerus bone. Depending on the severity of the dislocation, your physician will typically prescribe physical therapy to help stabilize the shoulder joint and protect it during a recovery phase.. With frequent dislocations, the shoulder can become unstable as many structures in the shoulder get damaged and become too lax. By strengthening the muscles around the shoulder, stability can be increased in the shoulder, preventing future dislocations.. At times, dislocations can be quite severe and lead to tearing of cartilage, tendons, ligaments or muscles. In this case, surgery is often needed. After surgery physical therapy is an important part of recovery and returning to normal activities.. How physical therapy helps ...
Open dislocations are infrequent, often associated with damage to the neuro vascular structures. We present an unusual case of an open antero-lateral dislocation of the elbow, which was not associated with any vascular or neural injury. A 34 year female dance instructor sustained an open dislocation of her elbow. Surgical exploration was undertaken. No major neurovascular injury was present. There was almost complete disruption of all the muscular and ligamentous attachments to the distal humerus and the proximal radius and ulna, which were not formally repaired during surgery. The elbow was found to be very unstable, and was placed in a back slab. The functional recovery was complete in about six months, the patient regaining full range of elbow movement. Elbow dislocations without associate fractures are adequately treated by manipulation and reduction, in spite of the almost complete disruption of the soft tissues around the joint.

What are the hip replacement dislocation symptoms? Even though a dislocated joint can happen to anyone at any age if they end up falling or face other types of trauma, older people are more likely to see dislocated joins.
All dislocations require immediate medical attention since fractures can also occur with dislocations.. Initial treatment of a dislocation includes R.I.C.E. (rest, ice, compression, and elevation). Dislocations may reduce spontaneously, meaning the bone ends may go back into place by themselves. However, for those dislocations that do not go back into place, your childs physician will need to place the joint back into its proper position so it will heal. Your child will receive sedation to help him or her remain comfortable before the procedure. Sedation will also help the muscles around the dislocated joint relax, so the joint can be put back into place more easily.. Your childs physician may recommend any of the following to help reduce the dislocation or promote healing afterwards:. ...
We employ discrete dislocation dynamics to establish a continuum-based model for the evolution of the dislocation structure in polycrystalline thin films. The Taylor equation is evaluated and expressions are developed for the density of active dislocation sources, as well as dislocation nucleation and annihilation rates. We demonstrate how the size effect naturally enters the evolution equation. Very good agreement between the simulation and the model results is obtained. The current approach is based on a two-dimensional discrete dislocation dynamics model, but can be extended to three-dimensional models ...
Dislocations occur when two bones that originally met at the joint detach. Dislocations should not be confused with Subluxation. Subluxation is when the joint is still partially attached to the bone. When a person has a dislocated jaw it is difficult to open and close the mouth. Dislocation can occur following a series of events if the jaw locks while open or unable to close. If the jaw is dislocated, it may cause an extreme headache or inability to concentrate. When the muscles alignment is out of sync, a pain will occur due to unwanted rotation of the jaw. If the pain remains constant, it may require surgery to realign the jaw. Depending on the severity of the jaws dislocation, pain relief such as paracetamol may assist to alleviate the initial chronic pain. If the pain relief is taken for an extended period of time, it may negatively affect the person while talking, eating, drinking, etc. The symptoms can be numerous depending on the severity of the dislocation injury and how long the ...

I dislocated my knee once. Probably the most pain I have ever been in in my life. It took 2 ambulance crews 2 hours, 2 bottles of gas and an injection to finally manage to get me to the hospital. They kept hoping it would pop back in if they tried to move , it didnt and eventually they gave up.Doctor on duty walked over, looked at it, said I know what to do and grabbed my kneecap (which was round the side of my leg) and tried to force it back into place. I screamed like a girl. He eventually decided that wasnt going to work either so they knocked me out completely to reset it. I spent 6 weeks with a full length cast on, followed by an operation on each knee to move the tendons over to prevent further dislocations. The operation apparently involved chipping out the bit of bone where the tendons attach, making a little hole for it a bit further over and sticking the bit of bone back in. Another 6 weeks in plaster for each leg. That was about 7 years ago, no dislocations since, but on the down ...
Dislocations are topological line defects in three-dimensional crystals. Same-sign dislocations repel according to Franks rule vertical barb(1) + b(2)vertical bar(2) , vertical barb(1)vertical bar(2) + vertical barb(2)vertical bar(2). This rule is broken for dislocations in van der Waals (vdW) layers, which possess crystallographic Burgers vector as ordinary dislocations but feature surface ripples due to the ease of bending and weak vdW adhesion of the atomic layers. We term these line defects ripplocations in accordance to their dual surface ripple and crystallographic dislocation characters. Unlike conventional ripples on noncrystalline (vacuum, amorphous, or fluid) substrates, ripplocations tend to be very straight, narrow, and crystallographically oriented. The self-energy of surface ripplocations scales sublinearly with ,b,, indicating that same-sign ripplocations attract and tend to merge, opposite to conventional dislocations. Using in situ transmission electron microscopy, we directly ...

The purpose of this work is the numerical resolution, in the case of anisotropic elasticity, of the problem of a dislocation parallel and near to the two free surfaces of a thin bicrystal. This case is obtained while making the period of a network of misfit dislocations much greater than the thickness of the two foils. As a result, in the vicinity of the dislocation, the limiting bondary conditions will be close to that of Volterra translation dislocation. The elastic fields of displacement and stress are calculated for various orientations of the burgers vector. Before this calculation, we tested the precision of the results of the program by comparing the interfacial relative displacement obtained from this one to the results of the analytical expression describing this same displacement. The thin bicristal Al/Al2Cu, that made the object of several investigations, is treated like example. The results obtained are compared to those obtained in isotropic elasticity.|br||br|Este trabajo aborda la
Waves that have an isotropic intensity distribution about the propagation axis may carry well-defined, quantized orbital angular momentum. The angular momentum is nonzero in the presence of screw dislocations. It is shown that these dislocations can be represented by a complete orthogonal set of functions (such as the Gauss-Laguerre set, which is valid for the paraxial approximation). Representing anisotropic dislocations by a superposition of isotropic ones provides easy derivation of various quantities related to the angular momentum, such as its expectation value and the uncertainty. Concentrating on dislocations that are solutions of the Laplace equation, we propose two natural and convenient ways of parameterization that bring forth their isotropic components as well as the geometrical properties of their phase map.. © 1996 Optical Society of America.

InSb films grown on GaAs exhibit a thickness-dependent electron mobility, which we determined to be due to scattering of free carriers from dislocations. Of particular importance in our work is that we showed that other factors, including surface and interface roughness, do not play a significant role in limiting the electron mobility of the films. In addition, we proved that it is the strain field associated with the dislocations, rather than the carrier depletion region surrounding them, which scatters the free carriers and limits the electron mobility (ref). We have recently completed a follow up investigation of the effects of various buffers on the electronic properties of n-type InSb films, showing that ionized impurity scattering competes with the scattering associated with the dislocation strain fields (ref). One of our long-term interests is to develop more sophisticated models to explain and predict the effects of dislocations on the properties of a variety of heteroepitaxial films.
Numerical algorithms for discrete dislocation dynamics simulations are investigated for the purpose of enabling strain hardening simulations of single crystals on massively parallel computers. The algorithms investigated include the /(N) calculation of forces, the equations of motion, time integration, adaptive mesh refinement, the treatment of dislocation core reactions, and the dynamic distribution of work on parallel computers. A simulation integrating all of these algorithmic elements using the Parallel Dislocation Simulator (ParaDiS) code is performed to understand their behavior in concert, and evaluate the overall numerical performance of dislocation dynamics simulations and their ability to accumulate percents of plastic strain.
For surgeons starting out with the Pinnacle Hip System, the learning curve is minimal, and the design of the shell and liner is such that positive head/neck ratios can be achieved, allowing for increased stability of the construct. I have used the posterior approach during my career and this approach has historically had a higher dislocation rate than the direct lateral or anterior approaches.5 However, my dislocation rate with Pinnacle is typically less than 1%, aided by the ability to use 36-mm diameter heads with desirable head/neck ratios, in the majority of my cases. In the past I tended to use as large a head as possible to assist in minimizing dislocation. Yet, recent literature suggests a benefit to be gained from a dislocation standpoint with increasing head size up to 36 mm in diameter.6 However, it is still comforting to see these large heads in situ given the jump distance to dislocate the head is quite large. Therefore, I still use as large a head as possible against polyethylene. ...

First-principles calculations are used to investigate the partial dislocations in 4H-SiC. We show that the stability of the dislocation cores and the Peierls barriers of the first kind are chargestate dependent. In intrinsic bulk the partials are stable in the neutral asymmetric reconstructions. These reconstructions have no deep states and are characterized by high Peierls barriers. In strongly doped regime the symmetric reconstructions can become more stable. These reconstructions are always electrically active with a half filled band across the band gap. In particular the symmetric reconstructions of the 30° partial have a lower Peierls barriers than the respective asymmetric ones and could be the cause of the 1.8 eV electroluminescence peak observed under carrier injection conditions.. ...

A multiscale modelling framework and an experiment campaign are used to study void swelling and Cu precipitation under irradiation. Several aspects regarding defect and solute diffusion under irradiation have been studied in this thesis.. First, a self-diffusion model in bcc Fe has been constructed in order to describe the non-linear effects, especially the magnetic transition, around the Curie temperature. First principles calculations are applied to obtain the parameters in the model. The paramagnetic state is simulated by statistical sampling of randomly arranged spin states on each atom. The model fits well with the experimental observations.. Then, a combination of atomistic calculations and the finite element method (FEM) is developed in order to solve the diffusion equations of point defects, which are under the influence of a dislocation strain field. The dislocation bias, a key parameter in void swelling models, is hence obtained numerically. The method has been applied in different ...

My point here is that all of the so-called lifestyle diseases are also based on inflammation. I checked the research literature for studies of the response of each of these diseases to diets supplemented with omega-3 fish oils. Studies had been performed in each case. Reduction of inflammation by fish oil treatment was uniformly effective in reducing symptoms of all of the degenerative diseases. Other diseases that can be added to the inflammatory list are spinal disc problems and hypertension. It is interesting that disc dislocations are associated with coeliac, an inflammatory/autoimmune disease. It is also interesting that acne and depression are listed. Acne is indirectly associated with diet, but if sufferers shift to an anti-inflammatory diet, acne symptoms disappear. Depression associated with childbirth is particularly responsive to anti-inflammatory drugs, diet and exercise. Most of the symptoms associated with aging are just due to inflammation and are similarly responsive to ...
