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,...
Fixation of the Cemented Stem: Clinical Relevance of the Porosity and Thickness of the Cement Mantle
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...
Distal flow of polymethylmethacrylate (PMMA) bone cement during insertion of the femoral implant results in reduced pressure and cement-bone interdigitation (Markolf, Amstutz, 1976). Insertion of femoral cement plugs in the intramedullary canal to prevent distal flow of PMMA cement in total hip replacement during cementing of femoral prostheses is well accepted and has become current practice (...
Objective The purpose of this study was to determine the feasibility of screw fixation in previously augmented vertebrae with bone cement. We also investigated the influence of cement distribution pattern on the surgical technique. Methods Fourteen patients who required screw fixation at the level of the previous percutaneous vertebroplasty or balloon kyphoplasty were enrolled in this study. ...
In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proport...
background and aims. the aim of this study was to evaluate the sealing ability of kryptonite bone cement (doctors research group inc, southbury, ct, usa) in retrograde cavities by comparing with mineral trioxide aggregate (mta) (dentsply tulsa dental specialties, tulsa, ok, usa), amalgam and intermediate restorative material (irm) (dentsply caulk, milford, de, usa) using ultrasonic retrograde p...
background: patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (bcis) which is a leading cause of intraoperative complications. the purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients. methods: cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. a...
BACKGROUND Inferior vena cava filters (IVCF) are frequently used for preventing pulmonary embolism (PE) following deep venous thromboembolism. OBJECTIVES The present study was designed to investigate whether IVCF could prevent or impede the occurrence of bone cement implantation syndrome (BCIS), since PE is considered as the central mechanism of BCIS. MATERIALS AND METHODS Fifteen sheep wer...
