Drug-eluting Ti wires with titania nanotube arrays for bone fixation and reduced bone infection [PDF]

Nanoscale Research Letters, 2011
Abstract Current bone fixation technology which uses stainless steel wires known as Kirschner wires for fracture fixing often causes infection and reduced skeletal load resulting in implant failure. Creating new wires with drug-eluting properties to locally deliver drugs is an appealing approach to address some of these problems.

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Biomechanical effects of osteoplasty with or without Kirschner wire augmentation on long bone diaphyses undergoing bending stress: implications for percutaneous imaging-guided consolidation in cancer patients

European Radiology Experimental, 2019
Background Osteoplasty has been discouraged in long bones. However, despite a substantial lack of pre-clinical biomechanical tests, multiple clinical studies have implemented a wide range of techniques to optimise long bone osteoplasty.

Intramedullary bone formation after polylactic acid wire implantation

Journal of Materials Science: Materials in Medicine, 1994
Semi-crystalline poly-L-lactic acid (PLLA) wire was implanted intramedullary in rat tibiae to evaluate the fracture healing processes and the tissue reaction on the PLLA in a fractured bone. The fracture healing after PLLA implantation was compared to a sham-operated group of animals.

Quantum computational capability of a 2D valence bond solid phase [PDF]

, 2011
Quantum phases of naturally-occurring systems exhibit distinctive collective phenomena as manifestation of their many-body correlations, in contrast to our persistent technological challenge to engineer at will such strong correlations artificially. Here

Surgical treatment of retrosternal extraosseous Ewing Sarcoma in a 6-years old female: a clamshell approach with hemysternectomy and application of a non-crosslinked extracellular matrix [PDF]

, 2017
Background Ewing Sarcoma (ES) and Neuroblastoma (NB) belong to a family of tumours of primitive neuroectodermal origin (PNET) that occurs in both bone and soft tissue. Notwithstanding ES and NB are two distinct malignant tumours, sometimes there could be
