An Injectable Glass Polyalkenoate Cement Engineered for Fracture Fixation and Stabilization
Glass polyalkenoate cements (GPCs) have potential as bio-adhesives due to their ease of application, appropriate mechanical properties, radiopacity and chemical adhesion to bone. Aluminium (Al)-free GPCs have been discussed in the literature, but have proven difficult to balance injectability with mechanical integrity. For example, zinc-based, Al-free GPCs reported compressive strengths of 63 M...
متن کاملA Novel Glass Polyalkenoate Cement for Fixation and Stabilisation of the Ribcage, Post Sternotomy Surgery: An ex-Vivo Study
This study investigates the use of gallium (Ga) based glass polyalkenoate cements (GPCs) as a possible alternative adhesive in sternal fixation, post sternotomy surgery. The glass series consists of a Control (CaO-ZnO-SiO2), and LGa-1 and LGa-2 which contain Ga at the expense of zinc (Zn) in 0.08 mol% increments. The additions of Ga resulted in increased working time (75 s to 137 s) and setting...
متن کاملCement augmentation of pathological fracture fixation.
Fixation of pathological fractures provides rapid pain relief and often restores mobility (Anderson et al 1978). The difficulty in achieving strong fixation in pathological bone may be overcome in part by adding bone cement (Harrington et a! 1976). This addition may, however, create fresh problems. The cement may harden before fracture reduction or implant insertion has been achieved, or some m...
متن کاملA Novel Injectable Borate Bioactive Glass Cement as an Antibiotic Delivery Vehicle for Treating Osteomyelitis
BACKGROUND A novel injectable cement composed of chitosan-bonded borate bioactive glass (BG) particles was evaluated as a carrier for local delivery of vancomycin in the treatment of osteomyelitis in a rabbit tibial model. MATERIALS AND METHODS The setting time, injectability, and compressive strength of the borate BG cement, and the release profile of vancomycin from the cement were measured...
متن کاملUltrasonically set glass polyalkenoate cements for orthodontic applications.
There is an accepted clinical requirement for a luting cement that can be command set upon satisfactory placement of an orthodontic appliance onto dentition. This work evaluates the suitability of ultrasound, imparted from a dental scaler, as a potential mechanism for achieving this. The net setting times and subsequent compressive strengths of a range of commercial and experimental glass polya...
