The position of the acetabular prosthesis is critical for preventing dislocation following total hip arthroplasty. The reliability of a mathematical model for radiographically calculated acetabular cup version was examined. A porous-coated anatomic acetabular prosthesis was mounted in a mold. Anteroposterior radiographs were taken with the cup in five(More)
Anteversion and vertical tilt of the acetabular prostheses in 50 consecutive total hip arthroplasties were prospectively evaluated during surgery (by the surgeon, using an alignment guide) and radiographically (calculated). From postoperative standardized radiographs vertical tilt was measured directly and anteversion was calculated. The mean error of(More)
Thyroid hormones play an essential role in lipid mobilization, lipid degradation, and fatty acid oxidation. Hypothyroidism has been associated with nonalcoholic steatohepatitis; however, the association between thyroid diseases and hepatocellular carcinoma (HCC) in men and women has not been well established. We investigated the association between(More)
OBJECTIVE To examine the safety of threaded-pin placement for fixation of distal radial fractures using a limited open approach. DESIGN A cadaver study. METHODS Four-millimetre Schanz threaded pins were inserted into the radius and 3-mm screw pins into the second metacarpal of 20 cadaver arms. Each threaded pin was inserted in the dorsoradial oblique(More)
Ensemble encoding is a distributed data representation scheme that uses multiple, overlapping receptive fields to encode inputs to MLP networks. The number, placement, and form of the receptive fields can have a significant impact on the effectiveness of ensemble encoding. We present four approaches, two based on descriptive statistics, and two based on(More)
