Automated Segmentation of Hip and Thigh Muscles in Metal Artifact-Contaminated CT using Convolutional Neural Network-Enhanced Normalized Metal Artifact Reduction [PDF]

arXiv, 2019
In total hip arthroplasty, analysis of postoperative medical images is important to evaluate surgical outcome. Since Computed Tomography (CT) is most prevalent modality in orthopedic surgery, we aimed at the analysis of CT image. In this work, we focus on the metal artifact in postoperative CT caused by the metallic implant, which reduces the accuracy ...

The anterior approach for conversion hip arthroplasty

Arthroplasty Today, 2019
Conversion of prior proximal femoral fracture fixation to hip arthroplasty is a fairly common and successful procedure, necessitated by various modes of failure.

2D/3D Registration of Acetabular Hip Implants Under Perspective Projection and Fully Differentiable Ellipse Fitting [PDF]

arXiv
This paper presents a novel method for estimating the orientation and the position of acetabular hip implants in total hip arthroplasty using full anterior-posterior hip fluoroscopy images. Our method accounts for distortions induced in the fluoroscope geometry, estimating acetabular component pose by creating a forward model of the perspective ...

Catastrophic failure of an acetabular total hip arthroplasty component mimicking a posterior dislocation

Arthroplasty Today, 2017
In our case study, we examine a case of catastrophic failure of a total hip arthroplasty acetabular component leading to complete central wear by the ceramic femoral head, requiring revision total hip arthroplasty.

Transfusions and blood loss in total hip and knee arthroplasty: a prospective observational study

Journal of Orthopaedic Surgery and Research, 2015
BackgroundThere is a high prevalence of blood product transfusions in orthopedic surgery. The reported prevalence of red blood cell transfusions in unselected patients undergoing hip or knee replacement varies between 21% and 70%.

Simultaneous bilateral minimally invasive total hip arthroplasty: A comprehensive review of the literature

Orthopedic Reviews, 2018
Several studies have reported that minimally- invasive total hip arthroplasty (MISTHA) may significantly reduce postoperative pain and results in faster postoperative rehabilitation when compared with the traditional lateral or posterior approach ...

UNSCT-HRNet: Modeling Anatomical Uncertainty for Landmark Detection in Total Hip Arthroplasty [PDF]

arXiv
Total hip arthroplasty (THA) relies on accurate landmark detection from radiographic images, but unstructured data caused by irregular patient postures or occluded anatomical markers pose significant challenges for existing methods. To address this, we propose UNSCT-HRNet (Unstructured CT - High-Resolution Net), a deep learning-based framework that ...

Comparison of outcome measures and complication rates following three different approaches for primary total hip arthroplasty: a pragmatic randomised controlled trial

Trials, 2018
Background Total hip arthroplasty is one of the most commonly performed surgical procedures worldwide. There are a number of surgical approaches for total hip arthroplasty and no high-level evidence supporting one approach over the other.
