Tech Hand Up Extrem Surg 2018 Nov 30. Epub 2018 Nov 30.

Cleveland Clinic.

Ulnar-sided carpometacarpal (CMC) joint fracture dislocations are relatively uncommon, frequently associated with fractures of the metacarpal base and/or hamate, and often sustained by young male individuals secondary to striking a hard object. The complexity of ulnar-sided CMC fracture dislocations necessitates careful restitution of anatomic alignment and joint congruency for mobility and stability. Miniaturization of the external fixation device has allowed application to the hand. Read More

Effect of Temperature on Deformation and Fracture Behaviour of Nanostructured Polycrystalline Ni Under Tensile Hydrostatic Stress by Molecular Dynamics Simulation.

J Nanosci Nanotechnol 2019 May;19(5):2723-2731

School of Mechanical, Materials, Mechatronic and Biomedical Engineering, University of Wollongong, Wollongong, NSW 2522, Australia.

Real materials have structural defects that are normally brought in during the processes of manufacturing and storage and often have a structure with abundant grains, as well as being subjected to multi-directional force conditions. The study of temperature's effect on plastic deformation mechanisms in polycrystalline materials bathed by a multi-axial force is still very rare and not clear. Therefore, we conducted very large-scale molecular dynamics simulations to study the deformation and fracture behaviour of nanostructured polycrystalline Ni under a pre-existing external tensile hydrostatic stress with various temperatures.

Scale-Free Modeling of Coupled Evolution of Discrete Dislocation Bands and Multivariant Martensitic Microstructure.

Phys Rev Lett 2018 Nov;121(20):205701

Department of Materials Science & Engineering, University of Michigan, Ann Arbor, Michigan 48109, USA.

A scale-free model for the coupled evolution of discrete dislocation bands and multivariant martensitic microstructure is developed. In contrast to previous phase field models, which are limited to nanoscale specimens, this model allows for treating the nucleation and evolution of martensite at evolving dislocation pileups, twin tips, and shear bands in a sample of an arbitrary size. The model is applied for finite element simulations of plastic strain-induced phase transformations (PTs) in a polycrystalline sample under compression and shear. Read More

The purpose of this prospective, randomized, controlled trial was to compare patient outcome following nonoperative care versus operative treatment with open reduction and tunneled suspension device (ORTSD) fixation for acute, type-III or IV disruptions of the AC joint.

Methods: Sixty patients aged 16 to 35 years with an acute type-III or IV disruption of the AC joint were randomized to receive ORTSD fixation or nonoperative treatment, following a power analysis to determine sample size. Read More

Percutaneous screws CT guided to fix sacroiliac joint in tile C pelvic injury. Outcomes at 5 years of follow-up.

SICOT J 2018 27;4:52. Epub 2016 Nov 27.

Department of Orthopedics and Traumatology, Azienda Ospedaliera "Gaetano Rummo", Benevento, Italy.

Introduction: The treatment of the sacroiliac joint (SIJ) vertical instability is a matter of current discussions and remains controversial. The aim of our study is the evaluation of the surgical management of SIJ vertical instability involving the use of cannulated screws introduced under CT guidance and local anesthesia.

Materials And Methods: In the set time frame of 7 years, 96 poly-trauma patients with Tile's type C fracture of the pelvis with vertical instability of the SIJ were treated. Read More

Open surgery after failed endovascular aortic repair remains an important therapy. The potential modes of stent-graft failure include: type I endoleaks; progression of the aortic disease at the landing zones or proximal/distal to them persistent false lumen perfusion in post-dissection aneurysms; retrograde aortic dissection; stent-graft infection; and stent-graft collapse, fracture, or dislocation. The mortality associated with those procedures can be up to 20% depending on the complexity of the operation and the comorbidities of the patient, especially the presence of graft infection.

Ternary Fe-Cr-Ni stainless steel alloys often exhibit a multi-step transformation known as double recalescence where primary ferrite converts to austenite during rapid solidification processes such as casting and welding. In addition to the volume free energy associated with undercooling between the phases, the free energy driving the transformation comes from two additional sources that are retained within the metastable solid-one from the primary phase undercooling and one from melt shear. A new physical model is proposed based on accumulation of defects, such as dislocations or tilt boundaries, and lattice strain. Read More

Hip hemi-arthroplasty for neck of femur fracture: What is the current evidence?

World J Orthop 2018 Nov 18;9(11):235-244. Epub 2018 Nov 18.

Orthopaedic Department, Leeds General Infirmary, Great George St, Leeds LS1 3EX, United Kingdom.

This editorial reviews and summarises the current evidence (meta-analyses and Cochrane reviews) relating to the use of hip hemi-arthroplasty for neck of femur fractures. Regarding the optimal surgical approach, two recent meta-analyses have found that posterior approaches are associated with: higher rates of dislocation compared to lateral and anterior approaches; and higher rates of re-operation compared to lateral approaches. Posterior approaches should therefore be avoided when performing hip hemi-arthroplasty procedures. Read More
