Cement fixation

Tourniquet use in total knee arthroplasty (TKA) provides a bloodless field to improve visualization; however, the arguments for improving cement fixation, decreasing operative time, and decreasing overall blood loss have not been supported by the literature. This study assessed the outcomes of tourniquetless TKA surgery in Hue Central Hospital.

Toxic heavy metals, i.e. copper (II), lead (II) and cadmium (II), can be removed from water by metallurgical solid wastes, i.e. bauxite waste red muds and coal fly ashes acting as sorbents. These heavy-metal-loaded solid wastes may then be solidified by adding cement to a durable concrete mass assuring their safe disposal. Thus, toxic metals in water have been removed by sorption on to inexpensive solid waste materials as a preliminary operation of ultimate fixation. Metal uptake (sorption) and release (desorption) have been investigated by thermostatic batch experiments.
