Bone Cement Formulation with Reduced Heating of Bone Cement Resin

Journal of Boron, 2021
Bone cement material is one of the key materials in bone surgery and orthopedic medicine. In this study, commercial polymethyl-methacrylate bone cement was mixed with boric acid and zinc borate to reduce the reaction temperature of the bone cement. The observation of temperature changes during the polymerization using laser thermometer and thermal ...

Factors Affecting Recollapse of the Augmented Vertebrae After Percutaneous Vertebral Augmentation: A Prospective Study

AGING MEDICINE, EarlyView.
To investigate the relevant factors of augmented vertebrae recollapse after percutaneous vertebral augmentation (PVA) for the treatment of osteoporotic vertebral compression fractures (OVCFs). Intervertebral cleft (IVC) and those with PVP intervention are at higher risk of recollapse.

A Comparison of Percutaneous Kyphoplasty with High-Viscosity and Low-Viscosity Bone Cement for Treatment of Osteoporotic Vertebral Compression Fractures: A Retrospective Study

Geriatric Orthopaedic Surgery & Rehabilitation, 2022
Background Osteoporotic vertebral compression fracture (OVCF) has become a health issue of worldwide concern. Percutaneous kyphoplasty (PKP) is one of the main surgical methods for OVCFs. This study aimed to evaluate and compare the clinical efficacy and

Atypical Clinical Course of Griscelli Syndrome Type 2 With Primarily Neurologic Presentation and Adult‐Onset in a 46‐Year‐Old Male

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Griscelli Syndrome Type 2 (GS2) is a rare autosomal recessive disorder caused by pathogenic mutations in the RAB27A gene. Typically, it is characterized by cutaneous hypopigmentation, immunodeficiency, with or without neurological abnormalities secondary to hemophagocytic lymphohistiocytosis (HLH). Without treatment, GS2 often results in fatal

COMPOSITION OF CEMENT LINES IN BONE [PDF]

Journal of Histochemistry & Cytochemistry, 1965
In cement lines and in adjacent Haversian systems from bone of orangutan and whale the content of mineral, organic matrix, and sulfur was determined microradiographically and the arrangement of the mineral part was studied by X-ray diffraction. Cement lines were often highly mineralized, maximum being 50% by volume. This value was a few per cent higher

A circumferentially flanged tibial tray minimizes bone-tray shear micromotion [PDF]

, 2005
Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening.

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

Advanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.
