“In‐Out‐In” Percutaneous Reduction Technique for Treatment of Valgus‐Impacted Femoral Neck Fractures: A Technical Trick and Case Series

Orthopaedic Surgery, Volume 15, Issue 1, Page 214-222, January 2023., 2023
“In‐out‐in” percutaneous reduction technique for treatment of valgus‐impacted femoral neck fracture with or without posterior tilt of the femoral head is safe and effective. In our case series, the technique achieved successful bone union and satisfactory function.

Fractality in tumor growth at the avascular stage from a generalization of the logistic-Gompertz dynamics [PDF]

, 2022
The dynamics between healthy and malignant cells at the avascular stage of growth is described by a set of chemical reactions representing the populations of both types of cells. We obtain a generalization of the logistic-Gompertz dynamics and study the consequences in terms of the properties of tumor growth associated with the Warburg effect, mitosis ...

Denosumab Can Prevent Collapse in Patients with Early‐Stage Steroid‐Induced Osteonecrosis of the Femoral Head by Inhibiting Osteoclasts and Autophagy

Orthopaedic Surgery, Volume 15, Issue 1, Page 256-265, January 2023., 2023
In patients with femoral head necrosis, strong positive reaction of LC3‐II could be identified in the cytoplasm of osteoclasts, in significant contrast to the background. A trabecula was surrounded by several LC3‐II‐positive osteoclasts, which were in close contact with the trabecula.

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

Structure Regularized Attentive Network for Automatic Femoral Head Necrosis Diagnosis and Localization [PDF]

arXiv, 2022
In recent years, several works have adopted the convolutional neural network (CNN) to diagnose the avascular necrosis of the femoral head (AVNFH) based on X-ray images or magnetic resonance imaging (MRI). However, due to the tissue overlap, X-ray images are difficult to provide fine-grained features for early diagnosis.
