Topological optimization in hip prosthesis design
Biomechanics and Modeling in Mechanobiology, 2009With particular interest on total hip arthroplasty (THA), optimization of orthopedic prostheses is employed in this work to minimize the probability of implant failure or maximize prosthesis reliability. This goal is often identified with the reduction of stress concentrations at the interface between bone and these devices.

Furlong Hydroxyapatite-Coated Hip Prosthesis vs the Charnley Cemented Hip Prosthesis
The Journal of Arthroplasty, 2010We report the results of a prospective trial comparing uncemented Furlong hydroxyapatite-coated total hip arthroplasty and cemented Charnley total hip arthroplasty. One hundred ninety-one patients were allocated into 2 groups depending on their year of birth.

Hip prosthesis: biomechanics and design
2022Total hip arthroplasty is currently one of the most successful and frequently performed surgical procedures. The hip replacement operation is required if the joint is affected by severe osteoarthritis, which is known to lead to pain and limitations in the joint functions, especially when the patient is not responding to conservative treatments ...

Large acetabular pelvic bone defects are frequently observed in the revision surgery of hip arthroplasty and in musculoskeletal oncology, representing a challenge in the reconstructive surgery. Three-dimensional (3D) printing is an emerging technology that have been attempted to improve the management of these patients.

A cementless system of total hip prosthesis
Archives of Orthopaedic and Traumatic Surgery, 1982It is essential that the prosthetic material should not be harmful to the human body, it should be strictly fitted to the body and it should have sufficient durability. To investigate those conditions of an artificial joints as mentioned above, it is important to have experimental studies using a model of the artificial joint in animals instead of a ...

The Self-Locking Metal Hip Prosthesis
The Journal of Bone & Joint Surgery, 1957Great judgment should be exercised in the selection of patients for replacement of the femoral head and a careful postoperative program should be planned. The importance of partial weight-bearing for a period of at least six months should be emphasized, with a gradual increase as roentgenograms show the reaction of bone about the prosthesis.

Elements of hip joint prosthesis reliability
Journal of Medical Engineering & Technology, 1977The performance of a total hip prosthesis is considered in terms of reliability. The causes requiring removal of the prosthesis are considered and methods of avoiding these difficulties are outlined. It is pointed out that most attention must be focused on the areas of low reliability.
