We retrospectively reviewed 44 consecutive patients
(50 hips) who underwent acetabular re-revision after a failed previous
revision that had been performed using structural or morcellised
allograft bone, with a cage or ring for uncontained defects. Of
the 50 previous revisions, 41 cages and nine rings were used with
allografts for 14 minor-column and 36 major-column defects. We routinely
assessed the size of the acetabular bone defect at the time of revision
and re-revision surgery. This allowed us to assess whether host
bone stock was restored. We also assessed the outcome of re-revision
surgery in these circumstances by means of radiological characteristics,
rates of failure and modes of failure. We subsequently investigated
the factors that may affect the potential for the restoration of bone
stock and the durability of the re-revision reconstruction using
multivariate analysis. At the time of re-revision, there were ten host acetabula with
no significant defects, 14 with contained defects, nine with minor-column,
seven with major-column defects and ten with pelvic discontinuity.
When bone defects at re-revision were compared with those at the
previous revision, there was restoration of bone stock in 31 hips, deterioration
of bone stock in nine and remained unchanged in ten. This was a
significant improvement (p <
0.001). Morselised allografting
at the index revision was not associated with the restoration of
bone stock. . In 17 hips (34%), re-revision was possible using a simple acetabular

A two-stage procedure was carried out on 57 patients with confirmed infection in a hip replacement.
Between 1990 and 2000, 123 hips in 110 patients were reconstructed for aseptic loosening using impaction bone grafting with frozen, irradiated, morsellised femoral heads and cemented acetabular components. This series was reported previously at a mean follow-up of five years. We have extended this follow-up and now describe the outcome of 86 hips in 74 patients at a mean of ten years. There have been 19 revisions, comprising nine for infection, seven for aseptic loosening and three for dislocation. In surviving acetabular reconstructions, union of the graft had occurred in 64 of 67 hips (95.5%). Survival analysis for all indications at ten years was 83.3% (95% confidence interval (CI) 68 to 89) and 71.3% (95% CI 58 to 84) at 15 years. Acetabular reconstruction using irradiated

Infection of a total hip replacement (THR) requires component removal and thorough local debridement. Usually, long-term antibiotic treatment in conjunction with a two-stage revision is required. This may take several months. One-stage revision using antibiotic-loaded cement has not gained widespread use, although the clinical and economic advantages are obvious.
Introduction. Large acetabular bone defects caused by aseptic loosening are common. Reconstruction of large segmental defects can be challenging. Various implants and operative techniques have been developed to allow further acetabular revision in cases where bone stock is poor. Reconstitution of bone stock is desirable especially in younger patients. The aim of the study was to review the clinical and radiological results of hip revision with structural acetabular bone grafts using fresh frozen
