Hip replacement

Background: Cemented hip arthroplasty with low viscosity cement has an increased rate of aseptic loosening of femoral components. The injection gun invented from a caulking gun could not withstand the medium or high viscosity cement. Methods: An experimental study was conducted by applying the Simplex P cement which was injected from both types of guns into a plastic test tube by one surgeon. The injection speed was calculated. The hardened cement was then imaged by CT scan and the bubbles inside were measured. The maximum trigger force and intra-cartridge pressures were measured.

Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant , that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi half replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement total hip arthroplasty or THA consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is currently one of the most common orthopaedic operations, though patient satisfaction short- and long-term varies widely. Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis. Other indications include rheumatoid arthritis , avascular necrosis , traumatic arthritis , protrusio acetabuli , certain hip fractures , benign and malignant bone tumors , arthritis associated with Paget's disease , ankylosing spondylitis and juvenile rheumatoid arthritis.

Review of Orthopaedic Trauma Review of Orthopaedic Trauma, Second Edition, embraces the full scope of adult and pediatric trauma care in one convenient resource. The expertly written and abundantly illustrated text emphasizes material likely to appear on board and training exams—presented in an outline format that is perfect for exam preparation or review of new and emerging topics. Osteoporosis: Assessment, Prevalence and Current Treatment Options In this book, Chapter One reviews the role and function of HDACs of different classes in different kinds of bone cells including osteoblasts and osteoclasts. Chapter Two evaluates the current state of research on mastocytosisinduced osteoporosis, and offers an overview of state of the art therapeutic measures. Chapter Three examines osteoporosis and the stomatognathic system.

Cemented implant fixation design principles have evolved since the s, and various femoral stem designs are currently in use to provide a stable construct between the implant—cement and cement—bone interfaces. Cemented stems have classically been classified into two broad categories: taper slip or force closed, and composite beams or shaped closed designs. While these simplifications are acceptable general categories, there are other important surgical details that need to be taken into consideration such as different broaching techniques, cementing techniques and mantle thickness. With the evolution of cemented implants, the introduction of newer implants which have hybrid properties, and the use of different broaching techniques, the classification of a very heterogenous group of implants into simple binary categories becomes increasingly difficult. We review these differing stem designs, their respective cementing techniques and geometries.

It has been advocated that total hip arthroplasty THA is probably the most successful surgical intervention performed in Medicine. In the s, Sir John Charnley not only introduced, but also modified and improved the technique of cemented arthroplasties. The concepts on biological , fixation established by Pillar and Galante served as the foundation for the development of uncemented implants that are now used worldwide. Currently, THA is a worldwide widespread surgery performed on millions of people.

It has become very clear that it is the surgical expertise, in particular the quality of the cementing technique, which will affect long-term outcome and success.
