introduction: ankle fracture is one of the most common joint fractures. x-ray and physical examination are its main methods of diagnosis. recently, ultrasonography (us) is considered as a simple and non-invasive method of fracture diagnosis. this study evaluated the diagnostic accuracy of us in detection of ankle fracture in comparison to plain radiography. methods: in this diagnostic accuracy ...

We show that a quotient group of a CI-group with respect to (di)graphs is a CI-group with respect to (di)graphs. In [1,2], Babai and Frankl provided strong constraints on which finite groups could be CI-groups with respect to graphs. As a tool in this program, they proved [1, Lemma 3.5] that a quotient group G/N of a CI-group G with respect to graphs is a CI-group with respect to graphs provide...

Introduction More than 50,000 people in Germany use a cochlear implant (CI). Potentially, revision surgery may become necessary any patient due to technical defect, medical or other reasons. The aim of the present study is analyze reasons leading CI reimplantation and calculate cumulative survival rate.

Introduction: The use of the latter is available, usually on a paid basis. In practice, five wing indices are most often used to discriminate wings: Ci, Disc.sh., Dbi, Ri, Pci. Due peculiarity structure wings, Ri and especially Disc.sh. determined with significant errors (Std.Err.), which reduces reliability classification as whole. goal work: authors set out find small number identification th...
