TLDR
The experiments with an implantation period up to six months demonstrate a tight bonding between the newly formed osseous tissue and the glass ceramic particles at the interface to achieve a more durable anchorage of bone cement in the tissue.Abstract:
Compound bone cement on a PMMA base with an additive of bioactive glass ceramic particles in different portions and different particle sizes are tested in animal experiments. The tissue reactions to extracorporal polymerized specimens and to in situ polymerized specimens are observed. The experiments with an implantation period up to six months demonstrate a tight bonding between the newly formed osseous tissue and the glass ceramic particles at the interface. The inflammatory reactions in the vicinity of the implant are small. It is the objective of the investigations to improve the adherance of the bone cement at the interface to achieve a more durable anchorage of bone cement in the tissue.read more

TL;DR: B-270 showed good combination of handling properties, high mechanical properties and showed higher bioactivity with minimal soft tissue interposition between bone and cement compared with commercial PMMA bone cement, which may increase the strength of the bone-cement interface and increase the longevity of cemented arthroplasties.

Bioactive polymethyl methacrylate‐based bone cement: Comparison of glass beads, apatite‐ and wollastonite‐containing glass–ceramic, and hydroxyapatite fillers on mechanical and biological properties

TL;DR: GBC shows promise as an alternative with improved properties to the conventionally used PMMA bone cement and the smaller spherical shape and glassy phase of the glass beads gave GBC strong enough mechanical properties to be useful under weight-bearing conditions.

In vivo cancellous bone remodeling on a Strontium-containing hydroxyapatite (Sr-HA) bioactive cement
C T Wong,William W. Lu,W K Chan,Kenneth M.C. Cheung,Keith D. K. Luk,D S Lu,A B M Rabie,L. F. Deng,J. C. Y. Leong +8 more
TL;DR: Results show that the Sr-HA cement is biocompatible and osteoconductive, which is suitable for use in treating osteoporotic vertebral fractures and in contrast to poly(methyl methacrylate) bone cement, which was neither osteoc conductive nor bioresorbable.

Bonding mechanisms at the interface of ceramic prosthetic materials
TL;DR: A theoretical model to explain the interfacial bonding is based upon in-vitro studies of glass-ceramic solubility in interfacial hydroxyapatite crystallization mechanisms, compared with in- vivo rat femur implant histology and ultrastructure results.

The long-term reaction of bone to self-curing acrylic cement
TL;DR: A study of 190 femora in 174 patients in whom self-curing acrylic cement had been present in the medullary cavity of the upper end of the femur for the fixation of an endoprosthesis for an average period of four years found changes for which the most likely explanation is chronic non-suppurative osteitis, though no collateral evidence of infection was found.

Experimental studies regarding the possible use of self-curing acrylic in orthopaedic surgery.
TL;DR: Although at the present time, no uses in orthopaedic surgery can be recommended unequivocally, it is believed that it may find a place following more research on the basic material, especially as rgards the heat of polymerization.
