A case of late iliac arterial thrombosis due to component migration after revision total hip arthroplasty

AbstractAlthough vascular injuries associated with primary and revision total hip arthroplasty are infrequent, these complications can have devastating effects that can lead to morbidity and even mortality. A few previous reports have described embolic distal limb ischemia secondary to a failed and migrated acetabular implant in discontinuity with the pelvis. We present a rare case in which a support ring from a failed and migrated acetabular cage construct led to injury of the common femoral artery. The patient developed acute thrombotic occlusion leading to distal extremity ischemia even after oral anticoagulant therapy. The patient was treated with embolectomy with a Fogarty catheter, replacement of the injured common femoral artery with an InteRing 8mm, and removal of the offending hardware. Recognition of the risks associated with failed and migrated components is important to prevent this complication for cardiologists as well as orthopedic surgeons.<Learning objective: Although vascular injuries associated with primary and revision total hip arthroplasty are infrequent, these complications can have devastating effects that can lead to morbidity and even mortality.

On Explicit Evaluations Around the Conformal Point in N=2 Supersymmetric Yang-Mills Theories

We show how to give the expression for periods, Higgs field and its dual of N=2 supersymmetric Yang-Mills theory around the conformal point. This is achieved by evaluating the integral representation in the weak coupling region, and by using analytic continuation to the conformal point. The explicit representation is shown for the SU(2) theory with matter fields and also for pure SU(N) and pure SO(2N) theory around the conformal point where the relation to the beta function of the theory is clarified. We also discuss a relation between the fixed points in the SU(2) theories with matter fields and the Landau-Ginzburg point of 2-D N=2 SCFT.Comment: 25 pages, LaTe

Grain size distributions of fault rocks: a comparison between experimentally and naturally deformed granitoids.

International audienceWe have investigated the grain size distribution (GSD) of granitoid fault rock by comparing experimentally produced gouge with fault rock from the Nojima Fault Zone. Triaxial experiments were carried out on wet and dry intact samples of Verzasca Gneiss at T = 300 and 500°C, Pc = 500 and 1030 MPa, ε = 0.013-1.6 x 10-4s-1. The GSD has been determined from SEM-micrographs and is characterized by the slope, D, of its log(frequency)-log(radius) histogram. The GSD is not fractal; we observe two slopes for all GSDs. The larger grains in experimentally deformed samples have a D value, D>, of 2.04 and 2.26 for feldspar and quartz gouge. Cracked grains yield values of D = 1.5-1.6.Increasing the confining pressure or temperature decreases the D-value. For grains smaller than ~2 μm another D-value, D = 2.02 for gouge and 1.64 for cracked grains; D< = 0.97. Grain size reduction in fault zones develops by a two-stage process: rupturing creates cracked grains; further displacement of fragments causes further comminution by wear and attrition. Cracked grains have been used to calculate the surface energy associated with faulting; it follows that this energy forms a small fraction in the total energy-budget of earthquakes
