The Preserved Thickness Ratio of the Femoral Head Contributes to the Collapse Predictor of Osteonecrosis

open access: yesOrthopaedic Surgery
Objectives The collapse of femoral head is a serious symptom of osteonecrosis of the femoral head (ONFH), resulting in hip pain and deformity. However, it is hardly possible to reestablish the femoral head nonoperatively once the collapse happens ...

A Biomechanical Study on the Use of Curved Drilling Technique for Treatment of Osteonecrosis of Femoral Head [PDF]

open access: yesarXiv, 2019
Osteonecrosis occurs due to the loss of blood supply to the bone, leading to spontaneous death of the trabecular bone. Delayed treatment of the involved patients results in collapse of the femoral head, which leads to a need for total hip arthroplasty surgery.

Novel nano‐hydroxyapatite coating of additively manufactured three‐dimensional porous implants improves bone ingrowth and initial fixation

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 111, Issue 2, Page 453-462, February 2023., 2023
Abstract Electron beam melting (EBM) has been used to fabricate three‐dimensional (3D) porous Ti‐6Al‐4V surfaces for acetabular cups in total hip arthroplasty. However, there are radiographic concerns regarding poor implant fixation and bone ingrowth around electron beam melted (EBMed) 3D porous cups.

Using anisotropic 3D Minkowski functionals for trabecular bone characterization and biomechanical strength prediction in proximal femur specimens [PDF]

open access: yesarXiv, 2020
The ability of Anisotropic Minkowski Functionals (AMFs) to capture local anisotropy while evaluating topological properties of the underlying gray-level structures has been previously demonstrated. We evaluate the ability of this approach to characterize local structure properties of trabecular bone micro-architecture in ex vivo proximal femur ...

Design and Analysis for a Diving‐Beetle‐Inspired Swimming Robot with Multi‐Flexible Appendages

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents a bionic underwater robot inspired by the swimming behavior of diving beetles. The robot features flexible appendages and a specialized motion controller to mimic the beetle's swimming gaits. Extensive experiments show improved thrust, speed, and maneuverability.

HU308 Mitigates Osteoarthritis by Stimulating Sox9‐Related Networks of Carbohydrate Metabolism

open access: yesJournal of Bone and Mineral Research, Volume 38, Issue 1, Page 154-170, January 2023., 2023
ABSTRACT Osteoarthritis (OA) is characterized by progressive, irreversible erosion of articular cartilage accompanied by severe pain and immobility. This study aimed to assess the effect and mechanism of action of HU308, a selective cannabinoid receptor type 2 (CB2) agonist, in preventing OA‐related joint damage. To test the assumption that HU308 could

Experimental analysis of femoral head intraosseous vascular anastomosis in the treatment of porcine subcapital femoral neck fractures

open access: yesHeliyon
Introduction: Femoral neck fractures are challenging injuries associated with a compromised blood supply to the femoral head, leading to a high risk of avascular necrosis and poor clinical outcomes. This study aimed to investigate the efficacy of femoral

Method for reconstructing femoral head blood supply by anastomosing the intraosseous artery

open access: yesHeliyon
Background: The reconstruction of femoral head blood supply is crucial in the management of avascular necrosis and related conditions. This study presents a method for reconstructing the femoral head blood supply by anastomosing the intraosseous artery ...
