Shock machine for the mechanical behaviour of hip prostheses: a description of performance capabilities [PDF]

Lubrication Science 24, 2 (2012) 45-60, 2012
The aim of this study was to describe the behaviour of a shock machine designed for testing hip prostheses. A microseparation between head and cup occurs inducing a shock of several times the body weight, leading to fracture of ceramic femoral components.

Prognostic factors in conversion surgery following nab‐paclitaxel with gemcitabine and subsequent chemoradiotherapy for unresectable locally advanced pancreatic cancer: Results of a dual‐center study

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 157-166, January 2023., 2023
For radical surgery after induction gemcitabine along with nab‐paclitaxel and subsequent chemoradiotherapy for unresectable locally advanced pancreatic ductal adenocarcinoma, CA19‐9 normalization and maintenance of good nutritional status during treatment until surgery were important for prolonged prognosis.

A fast and robust patient specific Finite Element mesh registration technique: application to 60 clinical cases [PDF]

Medical Image Analysis 14, 3 (2010) 303-17, 2010
Finite Element mesh generation remains an important issue for patient specific biomechanical modeling. While some techniques make automatic mesh generation possible, in most cases, manual mesh generation is preferred for better control over the sub-domain representation, element type, layout and refinement that it provides.

Effect of hip dysplasia on the development of the femoral head growth plate

Frontiers in Pediatrics, 2023
PurposeThe purpose of this study was to observe whether developmental dysplasia of the hip (DDH) affects the development of the femoral head growth plate and to analyze the risk factors.MethodsWe selected female patients aged between 11 and 20 years with

Fully Automated Organ Segmentation in Male Pelvic CT Images [PDF]

Balagopal A, Kazemifar S, Nguyen D, Lin M H, Hannan R, Owrangi A and Jiang S 2018 Fully automated organ segmentation in male pelvic CT images Phys. Med. Biol. 63 245015, 2018
Accurate segmentation of prostate and surrounding organs at risk is important for prostate cancer radiotherapy treatment planning. We present a fully automated workflow for male pelvic CT image segmentation using deep learning. The architecture consists of a 2D localization network followed by a 3D segmentation network for volumetric segmentation of ...

Evaluation of a pig femoral head osteonecrosis model

Journal of Orthopaedic Surgery and Research, 2010
Background A major cause of osteonecrosis of the femoral head is interruption of a blood supply to the proximal femur. In order to evaluate blood circulation and pathogenetic alterations, a pig femoral head osteonecrosis model was examined to address ...

Deep Learning-based End-to-end Diagnosis System for Avascular Necrosis of Femoral Head [PDF]

, 2020
As the first diagnostic imaging modality of avascular necrosis of the femoral head (AVNFH), accurately staging AVNFH from a plain radiograph is critical yet challenging for orthopedists. Thus, we propose a deep learning-based AVNFH diagnosis system (AVN-net). The proposed AVN-net reads plain radiographs of the pelvis, conducts diagnosis, and visualizes

The role of nitric oxide in the dorsomedial periaqueductal gray (dmPAG) column in cardiovascular responses in urethane‐anesthetized male rats

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 557-564, December 2022., 2022
In the current study, after anesthetized rat with urethan the femoral artery was cannulated, then its head was mounted on a stereotaxic instrument and drugs (saline‐NAME, L‐Arg, and L_Arg+ L‐NAME) microinjected into the dmPAG and cardiovascular responses that recorded by a Power lab were evaluated.

Treatment of osteonecrosis of the femoral head using autologous cultured osteoblasts: a case report

Journal of Medical Case Reports, 2008
Introduction Osteonecrosis of the femoral head is a progressive disease that leads to femoral head collapse and osteoarthritis. Our goal in treating osteonecrosis is to preserve, not to replace, the femoral head.

Infant hip screening using multi-class ultrasound scan segmentation [PDF]

arXiv, 2022
Developmental dysplasia of the hip (DDH) is a condition in infants where the femoral head is incorrectly located in the hip joint. We propose a deep learning algorithm for segmenting key structures within ultrasound images, employing this to calculate Femoral Head Coverage (FHC) and provide a screening diagnosis for DDH.
