Since their treatment require thorough excisions, bone substitutes have been studied for restoring bone continuity, but with limited efficacy due to the pathophysiology of bone infections; one of the classes which proved to be efficient were the BioActive Glasses [BAG], synthetic biocompatible inorganic materials with a controlled ionic release, with demonstrated properties of wound healing, osteoconduction, angiogenesis and antibacterial activity.
This paper presents the clinical experience from a Level 1 Trauma Centre where post-traumatic osteitis was treated using BioActive Glasses as bone fillers, demonstrating the potential clinical impact of these materials.
Introduction BioActive Glasses [BAG] are synthetic biocompatible inorganic materials that bond to surrounding tissues, and, due to a controlled ionic release induce wound healing, osteoconduction and angiogenesis, also demonstrating antibacterial activity [1-3], which is particular interest for orthopaedic surgeons due to several characteristics of bone infections.

Introduction Because it can improve the machining efficiency and the machining quality, the high-speed machining is usually used to machine the workpieces which are made of the brittle materials, the superhard materials, and the parts with special structures, being researched and used widely [1].
There are various experiential formulae for calculating the cutting force given in many literatures [2], but with the needs of machining the brittle materials, the superhard materials, the super-strength materials and the development of high-speed machining, these traditional experiential formulae are no longer suitable for the modern machining conditions.
