BacKGRoUnD The correct cementing technique for knee replacement involves maintaining the knee in extension for a protracted period of time to compress the cement effectively during polymerisation.1,2 Wound closure can be completed in flexion or extension with no difference in functional outcome3 but is often also completed with the leg maintained in extension due to decreased tissue tension. Wi...

Artificial cemented sand test samples were prepared by using ordinary Portland cement (OPC) as the cementing agent. Through uniaxial compression tests and consolidated drained triaxial compression tests, the stress-strain curves of the artificial cemented sand with different cementing agent contents (0.01, 0.03, 0.05 and 0.08) under various confining pressures (0.00 MPa, 0.25 MPa, 0.50 MPa and ...

OBJECTIVES To examine the long-term adhesion of seven dual-polymerizing cementing agents to human dentin in vitro. METHODS Two hundred and eighty extracted non-carious human molars were ground flat to expose dentin surfaces. The bond strengths of cementing agents with their respective bonding systems were examined: one compomer cement (PermaCem), five resin cements (RelyX ARC, Panavia F, Vari...

The authors present in this brief note a technique to facilitate the introduction of high viscosity bone cement into a cement syringe for retrograde high pressure cementing during total hip or revision knee arthroplasty. The nozzle part of the syringe is connected to the suction device used intra-operatively, to achieve a negative pressure in the syringe. Introduction of the cement into the syr...

Literature based review of lateral hip approach (MacFarland, Osborne) modifications offered by Bauer, Harding, Mills, Moscal and Mann is presented. Surgical technique for the Moscal and Mann approach is described. The approach allows easy access to the proximal femur for reaming, cementing, prosthesis orientation and leg-length discrepancy correction. It offers visualization of the joint superi...

The use of a keel in the tibial component during modern primary total knee arthroplasty (TKA) has become common, and its cementation may affect the future performance of the prosthesis. Although proponents of cementing the entire tibial component argue that this technique provides better initial fixation and may prevent aseptic loosening, reasons exist to apply cement only to the tibial basepla...

Complications related to joint imbalance may contribute to some of the most predominant modes of failure in total knee arthroplasty (TKA). These complications include instability, aseptic loosening, asymmetric component wear, and idiopathic pain. Fixation may represent a step that introduces unchecked variability into the procedure and may contribute to the incidence of joint imbalance-related ...

The purpose of this study is to improve the cementing quality of shale gas well by mud cake solidification, as well as to provide the better annular isolation for its hydraulic fracturing development. Based on the self-established experimental method and API RP 10, the effects of mud cake solidifiers on the shear strength at cement-interlayer interface (SSCFI) were evaluated. After curing for 3...
