Low-Intensity Pulsed Ultrasound and Halo Immobilization Is an Effective Treatment for Nonunion Following Traumatic Spondylolisthesis of the Axis

Journal of Neurological Surgery Reports, 2017
This case report describes a unique case involving traumatic spondylolisthesis of the axis that resulted in nonunion, angulation, and displacement after conservative treatment with a cervical collar, but which was successfully achieved union with halo ...

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 ...

Periosteal Mesenchymal Progenitor Dysfunction and Extraskeletally‐Derived Fibrosis Contribute to Atrophic Fracture Nonunion

Journal of Bone and Mineral Research, 2019
Atrophic nonunion represents an extremely challenging clinical dilemma for both physicians and fracture patients alike, but its underlying mechanisms are still largely unknown.

Extracorporeal Shock Wave Treatment for Delayed Union and Nonunion Fractures: A Systematic Review

Journal of Orthopaedics and Trauma, 2019
Objectives: Nonunions after bone fractures are usually treated surgically with risk of infections and failure of osteosynthesis. A noninvasive alternative is extracorporeal shock wave treatment (ESWT), which potentially stimulates bone regeneration ...

Development‐based In Vivo Bioreactor Strategy for Challenging Senescent Bone Reconstruction

Advanced Science, EarlyView.
We present a development‐based in vivo bioreactor strategy to generate rejuvenated bone grafts (vBR‐Bone) within aged hosts. By enclosing vBR‐Bone fragments within an asymmetric biomimetic periosteum, segmental femoral defects in aged mice were successfully repaired within 6 weeks. Mechanistically, the multifactors of vBR‐Bone reconstitute a remodeling

Multifunctional Bioactive Scaffold Facilitating BMSCs‐Driven Osteogenesis and Vascularization in Critical‐Sized Bone Defect Repair

Advanced Science, EarlyView.
A dual‐network bFGF@CB‐gel integrates: i) ChSMA scaffold (mechanical support/BMSCs delivery); ii) BC carrier (sustained bFGF release via EGFL/Itga2b and COMP/PI3K/AKT for adhesion/osteogenesis); iii) bFGF/PI3K/AKT/eNOS for angiogenesis. This rational, synergistic design addresses CSD bone regeneration challenges.

Injectable Porous Microspheres Loaded With Biomimetic Preconditioned Bone Marrow Mesenchymal Stem Cell‐Derived Exosomes for Vascularized Bone Regeneration

Advanced Science, EarlyView.
Schematic illustration of injectable PDA‐modified GelMA microspheres loaded with BioPre‐Exos for vascularized bone regeneration. ABSTRACT Critical‐sized bone defects remain a highly challenging clinical problem due to insufficient intrinsic self‐healing capacity.

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

Advanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.

The Risk Factors of Patients with Cruris Fracture Nonunion in Dr. Mohamad Soewandhie Hospital in 2021-2022: A Case-Control Study

Journal Orthopaedi and Traumatology Surabaya
Background: The crural region is highly susceptible to injury in Indonesia, with fractures being a common occurrence. If not properly treated, these fractures can lead to complications such as nonunion. To investigate the risk factors for nonunion cruris

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.
