Chronic Erosive Dislocation of Radial Head Resulting From Elbow Pyarthrosis—A Rare Delayed Complication of Fracture Dislocation of Elbow

Journal of Orthopaedics, Trauma and Rehabilitation, 2012
We present a case of elbow injury with chronic infection resulting in open dislocation of radial head together with elbow instability. The principle of treatment of elbow dislocation and the importance of ligamentous integrity would be discussed.

Predicting dislocation climb: Classical modeling versus atomistic simulations [PDF]

, 2011
The classical modeling of dislocation climb based on a continuous description of vacancy diffusion is compared to recent atomistic simulations of dislocation climb in body-centered cubic iron under vacancy supersaturation [Phys. Rev. Lett.

Open posterior dislocation of the knee with rupture of the patellar tendon and a tibial plateau fracture

Orthopedic Reviews, 2010
Knee dislocations are rare injuries. They represent a severe soft tissue injury following high-energy blunt trauma. We report a case of open posterior knee dislocation with rupture of the patellar tendon and a fracture of the tibial plateau.

Effect of solute atoms on dislocation motion in Mg: an electronic structure perspective. [PDF]

, 2015
Solution strengthening is a well-known approach to tailoring the mechanical properties of structural alloys. Ultimately, the properties of the dislocation/solute interaction are rooted in the electronic structure of the alloy. Accordingly, we compute the

Promoting Dynamic Recrystallization of Al-Zn-Mg-Cu Alloy via Electroshock Treatment

Metals, 2023
The application of high-strength Al-Zn-Mg-Cu alloy is seriously limited because of its poor formability. A novel electroshock treatment (EST) technique with low frequency combined with tensile deformation was proposed to address the issues of low ...
