Background: In this study we evaluated the treatment of giant cell tumor (GCT) of long bones using cryosurgery combined with curettage and polymethylmetacrylate (PMMA) cementing.Material and methods: From January 1999 to December 2004, twenty patients (mean age at the time of surgery 29.2 years) 13 females and 7 males were included in the study. Cortical disruption were presented in 7 patients ...
With the development of highly-deviated well cementing techniques, rotating casing cementing technology has got more and more attention. The rotating casing technique can improve the displacement efficiency of cement paste, and then enhance the quality of well cementation. In the stuck section, the rotating casing can redress the well to make the casing run sequentially. The casing endures shea...
Construction of geothermal wells that are effectively cemented and durable poses a significant operational challenge. Typically, lost circulation while drilling and cementing can make it seemingly impossible to place a complete column of cement behind casing strings. Incomplete cementation can lead to well failure caused by cyclic temperature loading on the casing that occurs throughout the lif...
