Pacing Clin Electrophysiol 2018 Dec 15. Epub 2018 Dec 15.

Department of Cardiology, Heart Center Brandenburg, Bernau, Berlin, Germany.

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

[Iatrogenic femoral head fracture during a closed reduction of posterior dislocation of hip. Case report].

Acta Ortop Mex 2018 Jul-Aug;32(4):234-239

Servicio de Cadera y Pelvis del Hospital General de Querétaro. Querétaro, México.

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

Initial Japanese experience and long-term follow-up with a new active fixation coronary sinus lead, the StarFix 4195.

J Cardiol Cases 2010 Jun 27;1(3):e176-e179. Epub 2010 Jan 27.

Division of Cardiology, Department of Integrated Medicine and Informatics, Ehime University Graduate School of Medicine, Shitsukawa, Toon, Ehime 791-0295, Japan.

Technologies associated with cardiac resynchronization therapy (CRT) devices and lead systems have progressed. However, dislocation after coronary sinus (CS) lead placement continues to be a problem. Furthermore, CS lead positioning at the site of the ventricular latest activation (detected by echocardiography) is often problematic due to large vessel size leading to the lead placement (wedge site) near the apical site.

University Clinic for Hand, Hip and Knee Surgery, Hospital Unit West, Building 8, Entrance N, 1st floor, Laegaardvej 12, 7500, Holstebro, Denmark.

Introduction: Dislocation is a serious and common complication and a great concern with the use of total hip arthroplasty (THA) when treating displaced femoral neck fracture (FNF). Dual-mobility (DM) THA might reduce the dislocation risk. We aim to report the dislocation and revision rate of primary DM THA in patients with displaced FNF. Read More

Department of Applied Physics, Aalto University, P.O. Box 11100, FI-00076, Aalto, Espoo, Finland.

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

Surface Energy Driven Liquid-Drop-Like Pseudoelastic Behaviors and In Situ Atomistic Mechanisms of Small-Sized Face-Centered-Cubic Metals.

Nano Lett 2018 Dec 13. Epub 2018 Dec 13.

The elastic strain of conventional metals is usually below ~1%. 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

Department of Radiology, The Royal National Orthopaedic Hospital NHS Trust, Brockley Hill, Stanmore, Middlesex, HA7 4LP, UK.

The patellofemoral joint is a complex joint that relies on both bone and soft tissues for its stability. Dysfunction of the patellofemoral joint, whether pain or instability, is a common cause of medial consultation. Thorough clinical and imaging assessment is important for managing these patients, who may require a combination of a bony and soft tissue surgical procedure. Read More

Department of Nuclear Science and Engineering, Massachusetts Institute of Technology, Massachusetts Institute of Technology, Cambridge, MA 02139, USA, Cambridge, Massachusetts, 02139, UNITED STATES.

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

Higher offset cross-linked polyethylene acetabular liners: is wear a significant clinical concern?

Hip Int 2018 Dec 7:1120700018815339. Epub 2018 Dec 7.

2 Towson Orthopaedic Associates, Towson, MD, USA.

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.

[Patellofemoral instability in children and adolescents].

Unfallchirurg 2018 Dec 7. Epub 2018 Dec 7.

AUVA Traumazentrum Wien, Standort Meidling, Kundratstr. 37, 1120, Wien, Österreich.

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.

"Floating elbow" injuries of the arm traditionally represent a combination of humeral shaft and forearm fractures which require anatomic rigid open reduction and internal fixation of all fractures to allow for early range of motion exercises of the elbow. There are published variants of the floating elbow injury which include ipsilateral diaphyseal humeral fracture, proximal ulna fracture with proximal radioulnar joint disruption, and ipsilateral diaphyseal humeral fracture with elbow dislocation and both bones forearm fracture.
