Interruption of the blood flow may occur in intra-osseous arteries within the femoral head. We report a 72-year-old woman who developed osteonecrosis of the femoral head 11 months after surgery involving massive cementing of a segmental distal femoral rotating hinge prosthesis to treat nonunion of the distal femur. The bone cement filled the cavity up to the femoral neck and the superolateral p...

47 consecutive cases of fracture neck femur in patients older than 70 years were managed by cemented hemiarthroplasty with Austin Moore prosthesis at a tertiary care teaching hospital with the objectives of studying the short come outcome and to compare the results with standard studies using uncemented Austin Moore prosthesis, to determine if cementing the prosthesis improves clinical outcome....

Although distal plugging is a common procedure to prevent distal flow of polymethyl-methacrylate (PMMA) cement during cementing of femoral prostheses, there is little biomechanical testing to confirm that (a) the plugs do not displace under cementing pressure, and (b) they do in fact occlude cement flow. Two designs of femoral intramedullary plugs, the Biostop G (Bioland, France) and Hardinge (...

BACKGROUND AND PURPOSE Despite the fact that there have been some reports on poor performance, titanium femoral stems intended for cemented fixation are still used at some centers in Europe. In this population-based registry study, we examined the results of the most frequently used cemented titanium stem in Norway. PATIENTS AND METHODS 11,876 cases implanted with the cemented Titan stem were...

Microbial-induced mineralization is a process in which metal ions the environment are processed by microorganisms, forming deposits of crystals with cementing and void-filling functions. Cementing can fix ions, reduce permeability, improve soil strength, play positive role remediation pollution control. This paper first introduces principle microbial-induced analyzes its mechanism action treatm...

Introduction: Grit blasted stem-cement interfaces have been advocated as a means of increasing the bond strength of the stem-cement interface in cemented total hip arthroplasty. Recent work has suggested that early cementing of rough stem surfaces can increase the bond strength of the interface when compared to the same interface cemented using very doughy cement [1]. Based on these findings, s...
