TLDR
In vitro apparatus is described which simulates conditions in the acetabulum during the Charnley-Muller type low friction arthroplasty procedure, providing a direct measurement of the temperature history of the surface where the bone would be in contact, and data indicate that the temperature at the bone-cement interface is linearly dependent on local cement thickness.About:

Cementing techniques for hip resurfacing arthroplasty: development of a laboratory model.
TL;DR: Fat-filling of lower-density carbon foam more closely simulates the cement penetration resistance and thermal properties of human femoral heads than does the denser (unfilled) material, which is sensitive to differences in cementing technique.

Curing characteristics of acrylic bone cement
Nicholas Dunne,John Orr +1 more
TL;DR: It was found that particular formulations of bone cements are suited to certain mixing methodologies, and it is vital that a full investigation is conducted on a cement mixing/delivery system prior to its introduction into the orthopaedic market.

Knochenzemente auf Basis von Polymethylmethacrylat
S. J. Breusch,K.-D. Kühn +1 more
TL;DR: Bone cements based on polymethylmethacrylate (PMMA) remain an important material for anchorage of artificial joints and their influence on practical application is reviewed.
Journal ArticleDOI
Fixation and loosening of hip prostheses. A review.
TL;DR: Studies using roentgen stereophotogrammetry and bone scintigraphy support a narrow definition of prosthetic fixation (viz., nonmigration), and consequently a broad definition of loosening, and indicates that if loosening occurs, it is initiated at an early stage.
Journal ArticleDOI
Temperature evaluation during PMMA screw augmentation in osteoporotic bone--an in vitro study about the risk of thermal necrosis in human femoral heads.
TL;DR: The results of this in vitro study reduce objections concerning the risk of thermal necrosis when augmenting cancellous bone around hip screws with up to 6.0 cc PMMA.

The use of an artificial femoral head for arthroplasty of the hip joint.
TL;DR: The results of a simple type of arthroplasty of the hip which is well tolerated even by elderly patients are made known, to suggest operation to patients who suffer more from loss of function than from pain.

Thermal conductivity of rock-forming minerals☆
Ki-iti Horai,Gene Simmons +1 more
TL;DR: In this paper, the thermal conductivity of 119 rock-forming minerals reveal the following empirical relationships: (1) K is a linear function of density for constant mean atomic weight (similar to Birch's law for the velocity of compressional waves); (2) the K of silicates is controlled by the structure of the silicon-oxygen network; (3) within a group of minerals of similar crystal structure and bonding, K decreases as the average atomic weight increases.
Journal ArticleDOI
A characterization of polymethylmethacrylate bone cement.
TL;DR: The dough time, setting time, handling time, and temperature rise were found to be most affected by environmental temperature and kneading of the dough mass, and as the set material ages, the residual monomer content gradually decreases and the strength increases.
