Dislocation of the epicardial pacemaker into the peritoneal cavity is an uncommon but potentially life-threatening complication.We report a case of a 74-year-old with an abdominally implanted epicardial pacemaker that migrated through the peritoneum to the excavatio rectovesicalis. The laparoscopic approach was chosen because of the increased risks of perioperative morbidity and decreased survival. Read More

The fracture dislocation of the hip is a rare lesion described up to 4 to 17% of the cases and usually secondary to automobile accidents. Generally of poor prognosis and with already well documented complications such as avascular necrosis of the femoral head, osteoarthritis and heterotopic ossification. The iatrogenic fracture of the neck or head of the proximal femur is a complication even more rare and is not documented its incidence in the world literature. Read More

Plastic deformation of micron-scale crystalline solids exhibits stress-strain curves with significant sample-to-sample variations. It is a pertinent question if this variability is purely random or to some extent predictable. Here we show, by employing machine learning techniques such as regression neural networks and support vector machines that deformation predictability evolves with strain and crystal size. Read More

As the metals size decrease to approximate a few nanometers, their elastic strains can approach ~8%, and usually exhibit pseudoelastic strain that can be as large as ~35%. Previous studies suggested that the pseudoelastic behaviors of nanocrystals were attributed to distinctive mechanisms, including the release of stored elastic energies and the temperature-enhanced surface diffusion etc. Read More

A dislocation, just like a phonon, is a type of atomic lattice displacement but subject to an extra topological constraint. However, unlike the phonon which has been quantized for decades, the dislocation has long remained classical. This article is a comprehensive review of the recent progress on quantized dislocations, aka the "dislon" theory. Read More

Introduction:: Total hip arthroplasty (THA) is the 2nd most common total joint replacement surgery in the United States. However, not all THA devices perform well and need revised for several reasons including dislocation. Higher offset acetabular liners reduce this problem by creating a more anatomically/biomechanically natural hip joint, increasing soft-tissue tension, and accommodating larger femoral heads in smaller acetabular cups via increased polyethylene thickness.

Dislocation of the patella is one of the most common knee injuries in childhood and adolescence. After detailed clinical and radiological clarification, conservative functional treatment with special orthotic devices is most commonly applied in patients with a primary dislocation without concomitant injuries; however, the redislocation rate after conservative treatment has been reported in the literature to be between 35% and 70%, depending on the risk factors present. Therefore, numerous surgical treatment options exist which are sometimes again associated with high redislocation rates and others can lead to early arthrosis of the patellofemoral joint when used indiscriminately.
