We measured the formation of a Staphylococcus aureus biofilm in vitro on unloaded and gentamicin-loaded bone cements (CMW3 and Palacos R) and related the formation to antibiotic release rates. All experiments were done in triplicate. Microbial growth on gentamicin-loaded cements occurred despite the release of antibiotic. Biofilm formation on gentamicin loaded CMW3 bone cement was one fourth to...

Using a modern cementing technique, we implanted 22 stereolithographic polymeric replicas of the Charnley-Kerboul stem in 11 pairs of human cadaver femora. On one side, the replicas were cemented line-to-line with the largest broach. On the other, one-size undersized replicas were used (radial difference, 0.89 mm sd 0.13).CT analysis showed that the line-to-line stems without distal centraliser...

INTRODUCTION: Skeletal metastases frequently occur in patients suffering from breast cancer, the spine being the most common site. An improved survival rate of breast cancer has led to a rise in the incidence of skeletal metastases, resulting in serious morbidity (e.g. collapsed vertebrae) and a marked decrease in quality of life. The management of spinal metastatic lesions currently involves i...

INTRODUCTION Mechanical alignment deviation after total knee arthroplasty is a major reason for early loosening of the prosthesis. Achieving optimum cement penetration during fixation of the femoral and tibial component is an essential step in performing a successful total knee arthroplasty. Bone cement is used to solidify the bone and prosthesis. Thickness imbalance of bone cement leads to the...

Introduction: Periprosthetic joint infections (PJI) are increasing as a result of increased major joint arthroplasty (MJA). Classical treatment of PJI is a two-stage revision. However, this approach results in morbidity and is not cost effective. We investigated whether covering of the implants with bone cement is sufficient for eradication of microorganism on biofilm. Materials and methods: 24...

Recent in vitro work has shown that sealing the acetabular notch with bone graft in bovine acetabulum samples results in improved cement penetration in the acetabular bone during total hip arthroplasty. Successful sealing of the notch may be identified on postoperative films by a lack of cement extrusion. This study aimed to assess the clinical effectiveness of this technique in preventing ceme...

Background. This article presents on the possible impact of liquid ozone, applied for perioperative, on the quality of surgical cement used to fill the marrow cavity in long bones. Material and methods. The research was conducted on fresh on fresh long bone samples from slaughter animals. After routine cleaning of the bone marrow cavity, the marrow channels were filled with surgical cement, usi...

Objective: This study was aimed to explore clinical effects of high viscosity bone cement in the treatment of osteoporotic vertebral compression fracture. Methods: A total of 90 patients with osteoporotic vertebral compression fracture were selected from our hospital as the study objects and were randomly divided to control group and observation group with 45 cases in each. All patients underwe...

A retrospective study evaluated 75 total hip arthroplasties performed over a 4-year period using 4 different cement restrictors. A harvested bone restrictor, polyethylene restrictor (Smith & Nephew, Richards Inc, Memphis, Tenn), Biostop G (Depuy Orthopaedics, Warsaw, Ind), and polymethylmethacrylate (PMMA) (Wright Medical Technology, Arlington, Tex) were compared for the percentage of failures,...

The aim of this review paper is to define the fixation of the cemented stem. Polymethyl methacrylate, otherwise known as "bone cement", has been used in the fixation of hip implants since the early 1960s. Sir John Charnley, the pioneer of modern hip replacement, incorporated the use of cement in the development of low frictional torque hip arthroplasty. In this paper, the concepts of femoral st...
