Femoral neck nonunion: new classification used in total hip arthroplasty in elderly patients

Гений oртопедии, 2022
Introduction The risk of the femoral neck fracture nonunion is 48 % with avascular necrosis of the femoral head being reported in 42 % of cases. There are many classifications of acute intra-articular fractures of the proximal femur and there are no ...

The Contributing Factors of Nonunion Bone Fractures: A Brief Review

Journal of Orthopedic and Spine Trauma, 2022
The skeletal system has a high healing capacity. A nonunion fracture occurs when the natural course of bone healing is impaired. Numerous local and systemic factors participate in the development of a nonunion fracture.

Exploring the causal relationship of gut microbiota in nonunion: a Mendelian randomization analysis mediated by immune cell

Frontiers in Microbiology
BackgroundEmerging research indicates that gut microbiota (GM) are pivotal in the regulation of immune-mediated bone diseases. Nonunion, a bone metabolic disorder, has an unclear causal relationship with GM and immune cells.

Early Radiographic Outcomes of Vascularized Pedicle Bone Grafting in Foot: A Case Series

Journal of Reconstructive Microsurgery Open, 2022
Background Navicular nonunion and talar avascular necrosis may result from limited blood supply predisposing to injury and impaired healing. Vascularized pedicled bone grafting is a promising adjunct to treat these challenging conditions, offering the ...

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

Advanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Biocompatibility and healing patterns in experimentally induced canine tibial fractures using Pedicle screw‐Rod external fixation

Animal Models and Experimental Medicine, EarlyView.
This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.
