Implicit Modeling of Screw Threads for Bone-implant Finite Element Analysis

Introduction The development and evaluation of orthopaedic devices are commonly assisted by finite element analysis [1]. Computational models are usually simplified through approximations to enable efficient simulations, without affecting the outcome of relative comparisons between different implant designs or configurations. The physical behavior of the bonescrew interface prior to osseointegr...

Generating and Evaluating Summaries for Partial Email Threads: Conversational Bayesian Surprise and Silver Standards

We define and motivate the problem of summarizing partial email threads. This problem introduces the challenge of generating reference summaries for partial threads when human annotation is only available for the threads as a whole, particularly when the human-selected sentences are not uniformly distributed within the threads. We propose an oracular algorithm for generating these reference sum...

Biomechanical analysis of single screw fixation for slipped capital femoral epiphysis: are more threads across the physis necessary for stability?

PURPOSE To evaluate single screw fixation stability, in the treatment of slipped capital femoral epiphysis, as a function of screw thread distribution across the physis. STUDY DESIGN In vitro biomechanical study. METHODS Thirty porcine proximal femurs were sectioned through the physeal line and stabilized with a cannulated 7.3-mm stainless steel AO screw. The distal 16 mm of each screw was ...
