Incorporation and Remodeling of Structural Allografts in Acetabular Reconstruction

Structural bulk allografts in acetabular reconstruction. Analysis of two grafts retrieved at post-mortem.

Two acetabula which contained large bone allografts introduced at revision arthroplasty were obtained at post-mortem. The allografts had been placed in superior defects to support cementless acetabular components, and both hips were functioning well at the time of death. Clinical radiographs demonstrated apparent healing of graft to host bone, no graft collapse and stability of the acetabular c...

Failure of structural acetabular allografts in cementless revision hip arthroplasty.

We investigated the radiographic and clinical course of 31 patients in whom a bulk acetabular allograft had been used during the cementless revision of a total hip replacement. Two patients died and two were lost to follow-up within 24 months, but of the remaining 27 acetabular components, 12 (44%) showed radiographic evidence of instability at a mean of 46 months. Five of these have been revis...

Bone Remodeling in Acetabular Reconstruction Using a Kerboull-Type Reinforcement Device and Structural Bone-Grafting in Total Hip Arthroplasty.

BACKGROUND The purpose of this study was to identify the long-term durability of the Kerboull-type reinforcement device (KT plate) in acetabular reconstruction for massive bone defects, assessing the remodeling of structural bone grafts. METHODS This study retrospectively evaluated 106 hips that underwent acetabular reconstruction using a KT plate between November 2000 and December 2010. Thir...

Acetabular Reconstruction Using Massive Allografts for Combined Cavitary and Segmental Defects

Revision surgery in high grade acetabular defects with thermodisinfected allografts.

AIM Due to new medical knowledge and legal restrictions, it is increasingly difficult to run a traditional allogenic bone bank so that alternative bone substitutes and methods of processing are being sought worldwide. METHOD In a prospective clinical study, the biological efficacy of thermodisinfected and then cryopreserved allogenic bank bone was investigated in 19 acetabular revisions in 18...
