Characterization and computational modelling of acrylic bone cement polymerisation [PDF]

, 2006
Total joint replacement is one of the most successful surgical procedures and is a proven treatment for arthritis. Despite low failure rates, the wide application of the treatment means that large numbers of prostheses fail and must be revised.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Effect of bone cement augmentation with different configurations of the dual locking plate for femoral allograft fixation: finite element analysis and biomechanical study

Journal of Orthopaedic Surgery and Research, 2023
Aims Implant failure in allograft reconstruction is one of the most common problems after treating a large bone defect for a primary bone tumor. The study aimed to investigate the effect of bone cement augmentation with different configurations of dual ...

Bone cements in depressed frontal bone fractures

Annals of Maxillofacial Surgery, 2019
Skull fractures can be classified into four major types; linear, depressed, diastatic, and basilar. Of these, a depressed skull fracture presents a high risk of increased intracranial pressure or hemorrhage to the brain. A compound depressed skull fracture results when a laceration over the fracture exposes the internal cranial cavity to the outside ...

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Biomechanical Effects of Cement Distribution in the Fractured Area on Symptomatic Osteoporotic Vertebral Compression Fractures: A Three-Dimensional Finite Element Analysis

Global Spine Journal, 2015
Introduction According to some clinical studies, insufficient cement distribution in fractured area and asymmetrical cement distribution around fractured area were thought to be the reasons for unrelieved pain and recollapse after percutaneous vertebral ...

Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants

Advanced Science, EarlyView.
The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...

Outcomes of cement beads and cement spacers in the treatment of bone defects associated with post-traumatic osteomyelitis

BMC Musculoskeletal Disorders, 2017
Background Cement spacers (Masquelet technique) have traditionally been used for the treatment of segmental bone defects. However, no reports have used cement spacers for the treatment of small/partial segmental bone defects associated with osteomyelitis
