Histology of 8 atypical femoral fractures

Acta Orthopaedica, 2014
Background and purpose — The pathophysiology behind bisphosphonate-associated atypical femoral fractures remains unclear. Histological findings at the fracture site itself may provide clues. Patients and methods — Between 2008 and 2013, we collected bone

Electrosensitive Heterogeneous Short Fibers via Acousto‐Electric Coupling for Sequential Bone Regeneration in Infectious Defects

Advanced Science, EarlyView.
Electrosensitive heterogeneous short fibers can accurately respond to ultrasonic field regulation through the synergistic interaction of piezoelectric and conductive dual elements. At an ultrasound intensity of 1.5 W cm−2, it can effectively activate bacterial peroxisome and necrotic apoptotic pathway and promote bacterial apoptosis.

Fracture-dislocations of the femoral head

Orthopaedics & Traumatology: Surgery & Research, 2013
This review describes bone and nerve injury mechanisms during a femoral head fracture-dislocation and outlines a novel classification system that uses computed tomography scanning (CT scan) to help determine how to best treat these fractures in an emergency setting or in chronic cases.

Reinstating Niche Failure in Diabetic Cranial Defects via Chronotaxic Signal‐Amplifying Fluidic Biomimetic Hydrogel

Advanced Science, EarlyView.
An in situ moldable GelSSO/PDA@SDF hydrogel functions as a chronotaxic signal‐amplifying biomimetic niche to restore regenerative failure in diabetic cranial defects. By sequentially releasing SDF‐1α‐loaded PDA nanoparticles and osteoinductive oligodeoxynucleotides, it orchestrates immunomodulation, progenitor recruitment, angiogenesis, and ...

Endoprosthetic Reconstruction for a Displaced Atypical Femoral Fracture in a Cancer Patient with Poor Prognosis

Case Reports in Orthopedics, 2018
Zoledronate or denosumab treatment is beneficial for cancer patients with bone metastasis. However, each agent may trigger atypical femoral fractures.

Treatment of pediatric closed femoral shaft fractures: A decline in use of external fixators over the last decade

Journal of Limb Lengthening & Reconstruction, 2017
Background: Femoral fractures represent 2% of all fractures in children. While external fixation was popular for managing pediatric closed femoral shaft fractures, other methods have recently increased in popularity.

Artificial Intelligence for Bone: Theory, Methods, and Applications

Advanced Intelligent Discovery, EarlyView.
Advances in artificial intelligence (AI) offer the potential to improve bone research. The current review explores the contributions of AI to pathological study, biomarker discovery, drug design, and clinical diagnosis and prognosis of bone diseases. We envision that AI‐driven methodologies will enable identifying novel targets for drugs discovery. The

Treatment of basicervical femoral neck fractures with proximal femoral nail antirotation

Journal of International Medical Research, 2019
Objective A basicervical femoral neck fracture, which is located at the junction between the femoral neck and intertrochanteric region, is a rare type of fracture. The treatment effects for this type of fracture vary.
