ABSTRACT
PURPOSE:
This study was undertaken to evaluate the clinical and radiographic results of acetabular revision arthroplasty using an uncemented big cup and a morselized impacted allograft. MATERIALS ANDMETHODS:
This study involved 81 hips of 77 patients experienced over a 2 year period (2-8 years 10 months). The bone defects of the acetabulum were classified by AAOS classification and by the Paprosky classification. We inserted an uncemented hemispherical cup by press-fitting technique as large size as possible. Only morselized impacted allograft was used for the bone defect.RESULTS:
The average Harris hip score was 95.9. One case (Paprosky type IIIB) received revision with only morselized allograft and failed to achieve initial stability. Therefore re-revision was performed with tricortical autograft and morselized allograft which has been well maintained until now for 3.5 years. Vertical migration and horizontal migration of more than 3 mm were noted in five cases and two cases, respectively. Rotational migration of more than 8 degree was not noted. A radiolucent line between bone and cup was seen in 9 cases, and a radiolucent line between host bone and grafted bone in 2 cases, this line was less than 2 mm large.CONCLUSION:
We believe this method is a good option in revision acetabular total hip arthroplasty.
