Bone cement reaches significant temperatures and is known to cause thermal and chemical damage to various tissues. All the reports of such damage occurred following a direct contact of the tissue or structure with cement. We report the case of a patient with a giant cell tumour of the proximal tibia who underwent curettage and bone cement application through a posterior approach and subsequentl...

We report the early failure, at a mean of 37 months, of 17 femoral prostheses due to aseptic loosening at the cement-bone interface. In every case the prosthesis had been manufactured with a surface coating designed to enhance the strength of the cement-prosthesis interface. It is postulated that improving the bond at the cement-prosthesis interface may transfer increased stress to the cement-b...

To determine whether plain radiographs accurately represent the true cement-bone interlock, a comparison was made between radiographs and macroscopic morphology on cross sections of 11 human femora into which a cemented endoprosthesis had been inserted. Four femora had been retrieved postmortem from patients with a hip arthroplasty, and seven cadaver femora were cemented under varying condition...

Local antibiotic delivery with antibiotic loaded acrylic bone cement has been used extensively in the management of chronic osteomyelitis and implant related infections. Though newer drug delivery vehicles are being investigated, it remains the most widely used local antibiotic delivery vehicle in orthopaedic surgery. Self-made antibiotic loaded bone cement beads, which are cheaper and antibiot...

BACKGROUND AND PURPOSE Many clinical reports have indicated that polished hip stems show better clinical results than rough stems of the same geometry. It is still unknown, however, what the mechanical effects are of different surface finishes on the cement at the cement-bone interface. We compared mechanical effects in an in vitro cemented hip arthroplasty model. METHODS Two sizes of double-...

INTRODUCTION: Osteosynthesis plates and screws are used in combination to fix complex fractures. These metallic fixation systems are used with success in healthy bone. But when important stresses apply on the bone-screw interface and when bone is weak, failure of the screw fixation may occur. An obvious mean to improve the fixation of a screw is to augment the surrounding bone with cement. Prev...

OBJECTIVES/HYPOTHESIS To evaluate the effectiveness of bone cement on mean postoperative air-bone gap (ABG) and the proportion of ABG closure to within 20 dB in patients undergoing ossicular chain reconstruction or revision stapes surgery. DATA SOURCES PubMed, Embase, and Central. METHODS A systematic search was conducted. Studies reporting original study data were included. Relevance and r...

BACKGROUND In reoperation of femoral prostheses, there is a higher percentage of complications associated with the extraction of bone cement from the femoral channel, which is technically and time consumingly tedious. Shockwaves have been used in medicine for years, particularly in urology for the destruction of concretions and orthopaedics, as a method of treating pain in patients with calcify...

BACKGROUND Antibiotic-impregnated bone cement is infrequently used in the United States for primary total hip arthroplasty because of concerns about cost, performance, and the possible development of antibiotic resistance and because it has been approved only for use in revision arthroplasty after infection. The purpose of this study was to model the use of antibiotic-impregnated bone cement in...

First generation glass ionomer bone cement was introduced by Wilson and Kent in 1970s and used in dental procedures . In 1989 Hehl et al. reported their experiences of fixing incudostapedial joint with glass ionomer cement . After this study many authors have presented their glass ionomer bone cement ossiculoplasty series [3,5] They showed that very satisfactory hearing improvements can be obta...
