Cement migration after THR. A comparison of charnley elite and exeter femoral stems using RSA.
Studies using roentgen stereophotogrammetric analysis (RSA) have shown that the femoral components of cemented total hip replacements (THR) migrate distally relative to the bone, but it is not clear whether this occurs at the cement-implant or the cement-bone interface or within the cement mantle. Our aim was to determine where this migration occurred, since this has important implications for ...
متن کاملGas migration through cement slurries analysis: A comparative laboratory study
Cementing is an essential part of every drilling operation. Protection of the wellbore from formation fluid invasion is one of the primary tasks of a cement job. Failure in this task results in catastrophic events, such as blow outs. Hence, in order to save the well and avoid risky and operationally difficult remedial cementing, slurry must be optimized to be resistant against gas migration phe...
متن کاملCement pulmonary embolism after vertebroplasty.
In recent years, the use of vertebral cementing techniques for vertebroplasty and kyphoplasty has spread for the treatment of pain associated with osteoporotic vertebral compression fractures. This is also associated with the increased incidence of complications related with these procedures, the most frequent being originated by leakage of cementation material. Cement can escape into the verte...

متن کاملcauses of gas migration through cement slurries and curring methods
it has been proven through laboratory experiments that the three types of gas migration through a cemented annulus can be eliminated by designing the correct cement mixture. the first type of void and, therefore, gas migration can occur between the casing and the cement. by adding the correct amount of magnetite to the cement, this void, and therefore the possible cause of gas migration, c...
