Bone preserving techniques for explanting the well-fixed cemented acetabular component

‘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 ...

Bone lysis in well-fixed cemented femoral components.

We have reviewed 25 cases of focal femoral osteolysis in radiographically stable, cemented femoral implants. In three hips retrieved at post-mortem from two patients, we have been able to make a detailed biomechanical and histological analysis. The interval between arthroplasty and the appearance of focal osteolysis on clinical radiographs ranged from 40 to 168 months, and in over 70% of the ca...

Fixation of the cemented acetabular component in hip arthroplasty.

Acetabular revision with impacted morsellised cancellous bone grafting and a cemented acetabular component: a 20- to 25-year follow-up.

We present an update of the clinical and radiological results of 62 consecutive acetabular revisions using impacted morsellised cancellous bone grafts and a cemented acetabular component in 58 patients, at a mean follow-up of 22.2 years (20 to 25). The Kaplan-Meier survivorship for the acetabular component with revision for any reason as the endpoint was 75% at 20 years (95% confidence interval...

Acetabular revision with morsellised allogenic bone graft and a cemented metal-backed component.

Failure of total hip arthroplasty with acetabular deficiency occurred in 55 patients (60 hips) and was treated with acetabular revision using morsellised allograft and a cemented metal-backed component. A total of 50 patients (55 hips) were available for clinical and radiological evaluation at a mean follow-up of 5.8 years (3 to 9.5). No hip required further revision of the acetabular component...
