‘Explanting’ the well-fixed, cemented acetabular implant

چکیده
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 the operation. It was thought that this might be attributable to the placement of the support under the pelvis.

Early failure mechanisms of constrained tripolar acetabular sockets used in revision total hip arthroplasty.
Fifty-eight patients received an Osteonics constrained acetabular implant for recurrent instability (46), girdlestone reimplant (8), correction of leg lengthening (3), and periprosthetic fracture (1). The constrained liner was inserted into a cementless shell (49), cemented into a pre-existing cementless shell (6), cemented into a cage (2), and cemented directly into the acetabular bone (1). Ei...

The objective of this study was to analyze the results of a cemented polyethylene model that captures the hip prosthetic head. In a retrospective study we reviewed 36 cemented constrained acetabular liners implanted in patients older than 75 years (mean 83, SD : 4.4), of which 30 patients were aged 80-90 years and 26 were women. The average period of follow-up of our patients was 25.4 months (1...
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 کاملTreatment of Bilateral Recurrent Dislocation of Hip Pros-thesis with Malpositioned Well-Fixed Shell: A Case Report
Dislocations of total hip prostheses cause pain and patient dissatisfaction. Recurrent dislocations are difficult to treat mainly when the acetabular metal shell is well-fixed. The purpose of this article was to describe the surgical technique used for the treatment of a bilateral recurrent posterior dislocation after a cementless total hip prosthesis, caused by excessive inclination of acetabu...
متن کاملClinical and Radiological Results over the Medium Term of Isolated Acetabular Revision
Acetabular cup loosening is associated with pain, reduced function, and instability of the implant. If such event happens while the femoral implant is in a satisfactory position and is well fixed to the bone, isolated acetabular revision surgery is indicated. The aim of this single-center retrospective study was to evaluate the clinical and radiological results over the medium term (12-month fo...
