Prospectively the outcome after total hip replacement with a new threaded acetabular cup design was compared to an established press-fit cup. After 1, 2 and 5 years, the 36-item Short Form Health Survey, Western Ontario and McMaster University Osteoarthritis Index and Harris Hip Score revealed no significant differences between the two groups (each group : n = 42 patients), except for a higher ...

APPROACH Our approach is divided into four subtasks: Task 1: Forces and failure modes in suction cup attachments. Define assays to investigate cup failure modes. Task II: Assessing the impact of tags and surface attachments on cetaceans. Using Computational Fluid Dynamics we will assess the drag forces created by various suction cup and tag housing combinations. Task III: Engineered suction cup...

INTRODUCTION Basic daily activities, such as walking and climbing stairs produce forces on the acetabular cup that results in shear forces throughout the contacting surface producing acetabular cup micromotion. Minimizing micromotion of the acetabular component is critical to the long term survival of total hip arthroplasty. A typical cementless acetabular component is coated with a porous surf...

INTRODUCTION The total hip replacement is a common surgical procedure in orthopaedics. However, the acetabular cup loosening is one of the major failure modes of cementless acetabular cup. Many researches point out that an unstable cup would induce a large micromotion under dynamic loading. This large micromotion would reduce the bone ongrowth on the cementless cup surface and prohibit the osse...

BACKGROUND Trabecular metal has shown promising results in experimental studies of bone ingrowth. Several clinical studies support these results. However, until now, no randomized clinical radiostereometric analysis (RSA) studies have been published. In this randomized RSA trial, we compared a new acetabular cup with a surface made of tantalum trabecular metal and a cup with a titanium fiber-me...

Glaucoma is the second leading cause of loss of vision in the world. Examining the head of optic nerve (cup-to-disc ratio) is very important for diagnosing glaucoma and for patient monitoring after diagnosis. Images of optic disc and optic cup are acquired by fundus camera as well as Optical Coherence Tomography. The optic disc and optic cup segmentation techniques are used to isolate the relev...

Substantial errors can be introduced to estimates of leaf resistance (r(l)) obtained from diffusion porometers unless precautions are taken to reduce the leaf-cup temperature difference (T(leaf) - T(cup)) to acceptable levels prior to measurement. When T(leaf) > T(cup), underestimation of leaf resistance occurs; the reverse applies when T(leaf) < T(cup).The effect is most pronounced under open-...

in this study, the effect of edible coating and osmotic dehydration, as pre-treatments before drying of cucurbit, were investigated. cucurbit samples were cut spirally and coated by carboxy methyl cellulose (cmc) 1% and ascorbic acid 0.1% solutions and then processed by osmotic dehydration. proportion of sample to solution was 1:10 and the solution containing sucrose %45, salt%25 and citric aci...

INTRODUCTION The term cancer of unknown primary site (CUP) syndrome is used to describe malignancies in which a complete diagnostic work-up detects metastases in the absence of an identifiable primary tumor. METHODS Based on a selective literature review, national and international guidelines, and the experience of the "Arbeitskreis CUP-Syndrom der Arbeitsgemeinschaft Internistische Onkologie...

OBJECTIVES To investigate the correlation between exposure of footballers in European clubs to match play in the months before the World Cup 2002 and their injuries and performances during that World Cup. METHODS The team doctors at 11 of the best football clubs in Europe prospectively recorded players' exposure and injuries during the 2001-2002 season (July 2001-May 2002). Sixty five players...
