چکیده
OBJECTIVE To review short term results of uncemented cup implantation and the fate of bulk femoral head autografts in patients with acetabular bone deficiency due to dysplasia of the hip. We used bone scintigraphy to assess the viability of the grafts. METHODS We treated 19 hip joints of 17 patients with osteoarthritis due to developmental dysplasia of the hip with uncemented total hip arthroplasty between 1997-2003 in the Department of Orthopedics and Traumatology, Gazi University, Ankara, Turkey. The average age was 49.1 (31-72 years), and the average follow up period was 36 months. We used femoral head autografts to reconstruct superolateral segmental deficiencies of the acetabuli. We evaluated the patients clinically and radiologically to assess acetabular loosening, and we used three-phase bone scintigraphy to evaluate the viability of the autograft. RESULTS There was no acetabular component revision throughout the follow up period. There was no radiological evidence of graft resorption or graft displacement in any of the patients. In bone scintigraphy, we observed hyperemia in the blood pool phase, and the osteoblastic activity of the bone graft was at the level of the neighboring iliac bone. CONCLUSION The application of a non-cemented acetabular component with femoral autograft in superolateral acetabulum deficiency increases the stability of the implant and increases the bone stock. It is not easy to evaluate the viability of the graft by the use of radiological methods. Bone scintigraphy gives sufficient information about the viability of the graft as a non-invasive method.

Position of the acetabular component determines the fate of femoral head autografts in total hip replacement for acetabular dysplasia.
We have reviewed 54 patients who had undergone 61 total hip replacements using bulk femoral autografts to augment a congenitally dysplastic acetabulum. There were 52 women and two men with a mean age of 42.4 years (29 to 76) at the time of the index operation. A variety of different prostheses was used: 28 (45.9%) were cemented and 33 (54.1%) uncemented. The graft technique remained unchanged t...

PURPOSE To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA). METHODS 62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent unc...
متن کاملTwenty-year survival of a cementless revision hip arthroplasty using a press-fit bulk acetabular allograft for pelvic discontinuity: a case report.
Acetabular revision in a total hip arthroplasty (THA) with pelvic discontinuity is uncommon and challenging. Optimal management remains controversial, particularly with graft and implant selection. Interpretation of outcomes is confounded by the heterogeneity of patterns of bone loss and the lack of long-term results in great numbers for any given choice of treatment. We report a revision THA u...

The present study analyses the long-term outcome of isoelastic hip prostheses and their influence on the extent of periprosthetic bone remodeling. Ninety-two patients (102 hips) with Isoelastic/Isotitan uncemented total hip arthroplasty were evaluated after an average of 13.4 years. The average age of patients at surgery was 42.5 years. The clinical outcome was assessed based on the Harris hip ...
