BACKGROUND Revision arthroplasty often requires anchoring of prostheses to poor-quality or deficient bone stock. Recently, newer porous materials have been introduced onto the market as additional, and perhaps better, treatment options for revision arthroplasty. To date, there is no information on how these porous metals interface with bone cement. This is of clinical importance, since these co...

It is with great interest that we read the article by Seo et al, “Percutaneous Osteoplasty for the Treatment of a Painful Osteochondral Lesion of the Talus: A Case Report and Literature Review,” published in the 2012 September/October issue of Pain Physician (1). This is a well-prepared case report which presents a novel surgical procedure using calcium polyacrylatehydroxyapatite cement in perc...

OBJECTIVES To compare bone autograft, bone cement, and demineralized bone matrix in functional and aesthetic outcomes and complications following cranioplasty for reconstruction of cranial defects. STUDY DESIGN Retrospective chart review. MATERIALS AND METHODS A retrospective chart review was performed of patients who underwent cranioplasty at a single institution between 1992 and 2012. The...

The present work concerns the preparation of bone cements based on poly(methyl methacrylate) (PMMA), used mainly for prosthesis fixation and cavity filling for correction of human bone failures. A typical bone cement recipe contains methyl methacrylate, which polymerizes in situ during cement application. An inherent problem of this reaction is the large amount of heat released during the cemen...

We investigated the feasibility of applying polymethylmethacrylate bone cement composited with biomimetic bone-mineralizsed collagen to percutaneous kyphoplasty (PKP). We performed PKP in 95 patients diagnosed with osteoporotic vertebral compression fracture. All patients had fractures of a single vertebral body, and they were divided randomly into control (group A, 47 patients) and experimenta...

Background and purpose - Stability and survival of cemented total hip prostheses is dependent on a multitude of factors, including the type of cement that is used. Bone cements vary in viscosity, from low to medium and high. There have been few clinical RSA studies comparing the performance of low- and high-viscosity bone cements. We compared the migration behavior of the Stanmore hip stem ceme...

Infections after orthopedic surgery are a very unwelcome outcome; despite the widespread use of antibiotics, their incidence can be as high as 10%. This risk is likely to increase as antibiotics are gradually losing efficacy as a result of bacterial resistance; therefore, novel antimicrobial approaches are required. Parabens are a class of compounds whose antimicrobial activity is employed in m...

conclusions with the average 89 months follow-up, no recurrence of the diseases was found in the patients. it seems that using of cement and oral anti-parasitic, after extensive resection of the lesion is a proper treatment of bone hydatid disease. introduction bone is an uncommon site of involvement in hydatid disease; with the prevalence of 0.5-2% among bone lesions. case presentation in this...

Bone cement augmentation procedures have been getting more position as a minimally invasive surgical option for osteoporotic spinal fractures. However, complications related to these procedures have been increasingly reported. We describe a case of bone cement dislodgement following cement augmentation procedure for osteoporotic spinal fracture by reviewing the patient's medical records, imagin...

BACKGROUND For osteoporosis or spinal metastases, percutaneous vertebroplasty is effective in pain relief and improvement of mobility. However, the complication rate (cement extravasation and fat embolisms) is relatively higher in the treatment of spinal metastases. The presence of tumor tissue plays a significant role in intravertebral pressure and cement distribution and thereby affects the o...
