At the time of surgery, posterolateral rotatory elbow instability, if present, was due to the crista fracture. At the time of follow-up, all elbows were clinically stable and had radiographic concentric reductions. Elbow

flexion and extension were a mean (and standard deviation) of 136 degrees +/- 6 degrees and 5 degrees +/- 8 degrees, respectively. The mean PREE score was 15 +/- 20, and the mean DASH was 13.5 +/- 18.

Conclusions: Crista supinatoris fractures are difficult to identify on standard elbow radiographs. Fracture management is based on an assessment of elbow stability and on appropriate treatment of the associated injuries.”
“Recently tissue engineering has become available as a

regenerative treatment for bone defects; however, little has been reported on the application of tissue engineering for this website regeneration of cleft defect tissues. Mesenchymal-derived stem cells were applied to different kinds GW4869 cell line of bone substitute and compared in different animal models, but their usage in human critical defects remained unclear. In this study we report 2 patients with unilateral alveolar cleft, treated with the composite scaffold of demineralized bone mineral and calcium sulphate (Osteoset) loaded with mesenchymal stem cells (MSCs). Computed tomograms showed 34.5% regenerated bone, extending from the cleft walls and bridging the cleft after 4 selleck screening library months in one case and in the other there was 25.6% presentation of bone integrity. The available data revealed the conventional bone substitute was not a suitable scaffold for the MSC-induced bone regeneration. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 108:e1-e6)”
“Tunable cylindrical TE01n mode cavity has been used for the measurement of the dielectric and magnetic properties of planar anisotropic metamaterials as a function of frequency. Experiments have been performed on

low loss dielectric samples covered with thin metal patterns consisting split-ring resonators (SRRs), creating a regular hexagonal lattice. In order to determine the two complex quantities, namely the effective permittivity in the plane of metamaterial and the effective permeability in the direction perpendicular to that plane, two metamaterial samples have been used one small sample consisting of only seven SRRs at the center of the substrate and another large sample, with a diameter larger than the diameter of the cavity, completely covered with SRRs. It has been shown that determination of the effective permittivity and permeability, that are three-dimensional quantities, requires an assumption of the effective thickness of the metamaterial samples. The resonance behavior of the permittivity and permeability for metamaterials consisting of a SRR lattice has been experimentally confirmed. (c) 2010 American Institute of Physics. [doi:10.1063/1.
