We performed total hip arthroplasty (THA) using a special acrylic self-curing bone cement (Bonemite), which contains tri-n-butylborane as the initiator. Its maximum temperature at curing is lower than that of a conventional bone cement (CMW). Fifty-eight THAs using Bonemite and 35 THAs using CMW were followed up for more than 8 years (12.5 years on average). At the 10-year follow-up, the surviv...

Introduction Frequently in joint replacement surgery, antibiotics are combined with acrylic cement to provide high local drug concentrations for prevention and treatment of infection. In 2003, the FDA approved the sale of single-antibiotic cement for use in septic arthroplasty cases. Such cements can now be purchased from various manufacturers. A major disadvantage of adding antibiotics to bone...

Metastasis is the most common cancer of the bone. These lesions cause significant pain and morbidity. Palliative treatment has been the mainstay in managing these patients. However, the introduction of minimally invasive techniques and the concept of filling metastatic bone lesions with acrylic cement has revolutionised the management of these patients. Such techniques are usually performed und...

Acrylic bone cement is self-curing cement comprising of liquid and powder component of methyl methacrylate (MMA). It has been used extensively in orthopedics; however, adverse effects were associated with its use. Hence we investigated in this paper the possibility of new cement utilizing methacrylates with lower toxicity than MMA. LD50s of candidate monomers were determined with administration...

alpha-Tricalcium phosphate bone cement, as formerly designed and developed by Driessens et al., consists of a powder composed by alpha-tricalcium phosphate (alpha-TCP) and hydroxyapatite (HA) seeds, and an aqueous solution of Na2HPO4 as mixing liquid. After mixing powder and liquid, alpha-TCP dissolves into the liquid and calcium deficient hydroxyapatite (CDHA), more insoluble than the former, ...

For the purpose of studying its applicability for acrylic cement removal during total hip revision surgery, experiments with an extracorporeal shock wave lithotriptor were carried out. High-energy shock waves (HESW) were focussed on discs of polymethylmethacrylate bone cement. The average discharge was 18.1 kV; the number of shock waves 0, 100, 250, 500, 1000, and 2000; the application rate was...

The disrupted function of the hip joint can be restored by means of total hip arthroplasty (i.e. reconstructive surgery of the joint) THA. This is a widely used medical strategy with high succes rates, world wide [1,2]. Among the failure scenarios of THA, aseptic loosening represents the main reason for revision of cemented hip implants [3]. Studies have shown that the two most frequent ways fo...
