Wear Rate, Particle Morphology, and Biocompatibility of Polyether‐Ether‐Ketone Femoral Heads Against Highly Cross‐Linked Polyethylene Acetabular Cups in Hip Prosthetic Couples

Fei Hu, Xinyue Zhang, Xiaobo Wu, Zhuocheng Lyu et autres

ABSTRACT Biological reactions to wear particles from artificial joint prostheses can lead to osteolysis, ultimately resulting in aseptic loosening and implant failure, which affect the longevity of the prosthesis and the patient's quality of life. Polyether‐ether‐ketone (PEEK) has emerged as a key …

Neuromodulation with a 3D-printed, patient-specific hand orthotic in stroke: A proof-of-concept fMRI case series on clinical application

Zikai Hua, Zhipeng Li, Ying Zhang

Three-dimensional (3D) printing holds great promise for creating patient-specific rehabilitative devices. While previous studies have demonstrated that behavioral interventions can induce cortical reorganization in stroke, direct evidence that a device alone—specifically, a patient-specific 3D-printed orthotic—can modulate brain function remains lacking. This proof-of-concept …

Prediction and Experimental Validation of Wear Zones in Artificial Ligaments Based on Finite Element Stress Analysis

Xiuling Huang, Leihao Chen, Xinyi Zhang, Junjun Zhu et autres

Long-term success of ACL reconstruction is often compromised by wear at bone-tunnel interfaces. This study establishes a digital computational-experimental pipeline that integrates image-based 3D reconstruction finite element stress mapping algorithms, and in vitro wear testing to predict and quantify the wear behavior …

Applicability of ASTM F543-23-A2 Standards Across Diverse Bone Screw Types

Zikai Hua, Bocheng Hu, Chao Wang

ABSTRACT ASTM F543-23-A2, Standard Specification and Test Methods for Metallic Medical Bone Screws, provides critical experiential data on the torque required by surgeons when securing screws in clinical settings. This study aimed to evaluate the universal applicability of ASTM standard default testing …

Simulation Study on the Surface Texturing Design of COC Hip Joints Based on Elastohydrodynamic Lubrication Model

Zhenhua Wu, Leiming Gao, Xiuling Huang, Zikai Hua

Post-operative feedback from hip replacement surgeries indicates that implanted ceramic artificial hip joints may produce abnormal noises during movement. This occurrence of joint noise is highly correlated with insufficient lubrication of ceramic-on-ceramic (COC) prostheses. Studies have shown that surface texture design can …

Imaging observation of intervertebral disc degeneration in patients with old thoracolumbar fracture-related kyphotic deformity

Xilong Cui, Ao Ding, Wen Yin, Wei Zhang et autres

Old thoracolumbar fracture with kyphosis (OTLFK) often results in low back pain, with intervertebral disc degeneration being a significant contributor. We hypothesized that patients with OTLFK exhibit distinct patterns of disc degeneration compared to those with chronic low back pain without kyphotic …

Characteristics and mechanical mechanisms of intervertebral disc degeneration in old thoracolumbar fractures with kyphosis: clinical observations and finite element analyses

Xilong Cui, Ao Ding, Junjun Zhu, Wei Zhang et autres

BACKGROUND: Low back pain is a common complication in patients with old thoracolumbar fractures with kyphosis (OTLFK), and intervertebral disc degeneration (IDD) is a major contributor. Mechanical abnormalities are believed to play a key role in the development to IDD. This study …
