Sealing the acetabular notch in cemented total hip arthroplasty. A radiological review of 380 cases.

چکیده
Recent in vitro work has shown that sealing the acetabular notch with bone graft in bovine acetabulum samples results in improved cement penetration in the acetabular bone during total hip arthroplasty. Successful sealing of the notch may be identified on postoperative films by a lack of cement extrusion. This study aimed to assess the clinical effectiveness of this technique in preventing cement escape and early radiolucent lines by review of early postoperative radiographs. We reviewed the post-operative radiographs of 380 consecutive patients who underwent primary total hip arthroplasty with implantation of the same flanged cemented polyethylene cup. The incidence, site and extent of cement extrusion and the incidence of any early postoperative radiolucent lines at the cement bone interface were measured. We found the rate of inferior cement escape in our series was 9.2%, compared to 36.4% in a previous study. We also found a lower rate of early radiolucent lines compared to historical controls. We believe placing bone graft on the medial/inferior wall prior to cementing helps to increase cement pressurisation by sealing the acetabular notch, as identified by reduced cement escape and early radiolucent lines.

Hip Arthroplasty and its Revision in a Child: Case Report and Literature Review
Juvenile idiopathic arthritis is the leading cause of hip replacement in young children. However, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. In this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip art...
متن کاملAcetabular 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...
متن کاملAcetabular components in total hip arthroplasty: is there evidence that cementless fixation is better?
BACKGROUND The use of cementless acetabular components in total hip arthroplasty has gained popularity over the past decade. Most total hip arthroplasties being performed in North America currently use cementless acetabular components. The objective of this systematic review and meta-analysis was to compare the survivorship and revision rate of cemented and cementless acetabular components util...

We have made a retrospective review of 185 cemented Charnley total hip arthroplasties performed between 1970 and 1974 to determine the relationships between radiological variables and failure of the femoral and acetabular components. We measured the acetabular wear, the orientation of the cup, the thickness and consistency of acetabular and femoral cement mantles, radiolucency and femoral align...
