Background: No scientific evidence exists regarding the amount of bone cement used and discarded in primarycemented Total knee arthroplasty (TKA). The aim of this study was to identify the exact amount of bone cement utilizedfor component fixation in primary TKA.Methods: In a prospective study carried out at five centers, 133 primary cemented TKAs were performed. One packof 40g Palacos bone cem...

Clinical outcome of cemented implants to revision total hip replacement (THR) is not as satisfactory as primary THR, due to the loss of bone stock and normal trabecular pattern. This study evaluated a bioactive bone cement, strontium-containing hydroxyapatite (Sr-HA) bone cement, in a goat revision hip hemi-arthroplasty model, and compared outcomes with polymethylmethacrylate (PMMA) bone cement...

various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. this study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bone ceme...

 Background and purpose: Bone cement implantation syndrome is an important factor in changing the hemodynamic status of patients during orthopedic surgery. Anesthesiology team and surgeons should be aware of these hemodynamic changes and prevent complications, so, the aim of this study was to investigate the hemodynamic changes in patients during the use of bone cement. Materials and methods: ...

An obvious means to improve the fixation of a cancellous bone screw is to augment the surrounding bone with cement. Previous studies have shown that bone augmentation with Calcium Phosphate (CaP) cement significantly improves screw fixation. Nevertheless, quantitative data about the optimal distribution of CaP cement is not available. The present study aims to show the effect of cement distribu...

OBJECTIVE The purpose of this study is to find the optimal stiffness and volume of bone cement and their biomechanical effects on the adjacent vertebrae to determine a better strategy for conducting vertebroplasty. METHODS A three-dimensional finite-element model of a functional spinal unit was developed using computed tomography scans of a normal motion segment, comprising the T11, T12 and L...

OBJECTIVE To compare biodegradable magnesium phosphate cement (Mg-cement), calcium phosphate cement (Ca-cement), and no cement on bone repair, biocompatibility, and bone adhesive characteristics in vivo in horses. ANIMALS 8 clinically normal adult horses. PROCEDURES Triangular fragments (1-cm-long arms) were created by Y-shaped osteotomy of the second and fourth metatarsal bones (MTII and M...

Many bioactive bone cements were developed for total hip replacement and found to bond with bone directly. However, the mechanical properties at the bone/bone cement interface under load bearing are not fully understood. In this study, a bioactive bone cement, which consists of strontium-containing hydroxyapatite (Sr-HA) powder and bisphenol-alpha-glycidyl dimethacrylate (Bis-GMA)-based resin, ...

OBJECTIVE To investigate the clinical effect of high and low viscosity bone cement in vertebroplasty for treatment of osteoporotic vertebral compression fractures. METHODS 40 cases of patients with osteoporotic thoracolumbar compression fractures admitted into department of orthopeadics in our hospital were reviewed. All patients were divided into high viscosity bone cement group (20 cases) a...

Growth hormone was incorporated into Polymethylmethacrylate (PMMA) with a view to improving the quality of the bone-cement interface. Growth hormone was released from the PMMA and delivered to the cells at the bone-cement interface . The in vivo response to the growth hormone loaded cement was compared to the plain cement , using light microscopy, transmission electron microscopy and scanning e...
