Total Knee Arthroplasty for Neglected Patellar Dislocation
Haseki Tıp Bülteni, 2014 Neglected permanent post-traumatic patellar dislocation is rarely seen. In this group of patients, secondary osteoarthritis may develop within years, consequently, patients suffer from pain.

Dislocation Mechanics of Metal Plasticity and Fracturing [PDF]
, 2020 The modern understanding of metal plasticity and fracturing began about 100 years ago, with pioneering work; first, on crack-induced fracturing by Griffith and, second, with the invention of dislocation-enhanced crystal plasticity by Taylor, Orowan and ...

Dislocation based modelling of engineering alloys [PDF]
, 2023 Plastic deformation in crystalline materials arises due to the nucleation and motion of line defects known as dislocations. Simulating large numbers of dislocations is a useful tool for understanding the plastic behaviour of metals and alloys.

Posterior Dislocation and Fracture—Dislocation of the Shoulder [PDF]
Acta Orthopaedica Scandinavica, 1980 Two cases of posterior dislocation (PD) and four cases of posterior fracture-dislocation (PFD) of the shoulder are reported. There was one bilateral PD and two bilateral PFD. One PD was treated with closed reduction but in three cases of PFD operative reduction was necessary.

Statistical dynamics of dislocation systems: The influence of dislocation-dislocation correlations [PDF]
Physical Review B, 2001 During plastic deformation of crystalline materials, the collective dynamics of interacting dislocations gives rise to various patterning phenomena. A crucial and still open question is whether the long range dislocation-dislocation interactions which do not have an intrinsic range can lead to spatial patterns which may exhibit well-defined ...

Line-tension model for plasticity as the Gamma-limit of a nonlinear dislocation energy [PDF]
, 2012 In this paper we rigorously derive a line-tension model for plasticity as the Gamma-limit of a nonlinear mesoscopic dislocation energy, without resorting to the introduction of an ad hoc cut-off radius.

Existence and stability of a screw dislocation under anti-plane deformation [PDF]
, 2014 We formulate a variational model for a geometrically necessary screw dislocation in an anti-plane lattice model at zero temperature. Invariance of the energy functional under lattice symmetries renders the problem non-coercive.

A discrete dislocation dynamics study aiming at understanding fatigue crack initiation [PDF]
, 2003 We use discrete dislocation dynamics to build a model for fatigue crack initiation in a surface grain. Dislocations are modeled as line singularities in an elastic medium where they can be generated from pre-existing sources, glide or annihilate.
