‘Explanting’ the well-fixed, cemented acetabular implant
BACKGROUND Patient support is frequently required during just one part of a procedure (eg the pelvis for the perineal portion of an abdominoperineal resection of the rectum). This is commonly achieved by placing a gel patient positioner underneath the pelvis. However, this positioner can remain in place for a long time and we had noticed that patients complained occasionally of back pain after ...
متن کاملAutomated assessment of polyethylene wear in cemented acetabular components using anteroposterior radiographs of total hip replacements
Polyethylene wear in the acetabular components of hip prostheses is implicated in loosening and failure. Radiographic measurement of wear is used to identify patients at risk and to assess prosthesis designs. This paper focuses on analysis of prostheses with cemented acetabular cups from anteroposterior (AP) radiographs. The articular surface of the femoral head and the acetabular rim marker ar...
متن کاملA technique to remove a stable all-polyethylene cemented acetabular liner in revision hip arthroplasty: A case report
INTRODUCTION The removal of a well-fixed acetabular component in a total hip arthroplasty can cause bone fractures, excessive bleeding, as well as extended bone loss. The reimplantation of a new acetabular component may be compromised. PRESENTATION OF CASE We report a technique using 2 cork-screws for removal a stable cemented acetabular component for the treatment of a recurrent dislocation ...
متن کاملA simple technique to remove well-fixed acetabular components in revision of total hip arthroplasty
Removing well-fixed acetabular components can be a challenge for orthopaedic surgeons in revision of total hip arthroplasty. Acetabular bone loss, fracture, and other complications occurred in extracting implants may result in instability and fail of revision. Thus, instruments are developed to avoid such complications. We report a simple technique by drilling a tunnel on the superolateral quad...
متن کاملFinite Element Analysis Stress Distribution Acetabular Cup Biomaterial FINITE ELEMENT ANALYSIS OF PERI-ACETABULAR STRESS OF CEMENTED, METAL-BACKED, AND POROUS TANTALUM BACKED ACETABULAR COMPONENTS
Introduction: In contemporary THA there are two broad approaches to acetabular cup design and materials. One is an all-polyethylene design with polymethylmethacrylate (PMMA) cement. PMMA possesses a modulus of elasticity of about 2 GPa, which is between that of trabecular and subchondral bone. The second more popular approach, especially for active, younger patients, is the porous metal-backed ...
