Acetabular Reconstruction in Total Hip Arthroplasty
The difficulties encountered in dealing with the bone deficient acetabulum are amongst the greatest challenges in hip surgery. Acetabular reconstruction in revision total hip arthroplasty can successfully be achieved with hemispherical components featuring a porous or roughened ingrowth surface and options for placement of multiple screws for minor acetabular defect. Acetabular component select...
متن کاملRe-revision of failed revision Total Hip Arthroplasty acetabular components.
While revision of total hip arthroplasty (THA) is being performed with increasing frequency, outcomes of repeated revisions have been rarely reported in the literature. The purpose of this study was to report mid-term outcomes of re-revision of failed revision THA acetabular components. We performed at least two revisions of the failed acetabular component in 57 patients (57 hips) between Augus...
متن کامل3D Printing Aids Acetabular Reconstruction in Complex Revision Hip Arthroplasty
Revision hip arthroplasty requires comprehensive appreciation of abnormal bony anatomy. Advances in radiology and manufacturing technology have made three-dimensional (3D) representation of osseous anatomy obtainable, which provide visual and tactile feedback. Such life-size 3D models were manufactured from computed tomography scans of three hip joints in two patients. The first patient had und...
متن کاملRevision Total Hip Arthroplasty with Retained Acetabular Component.
BACKGROUND Aseptic loosening and osteolysis commonly limit the survivorship of total hip prostheses. Retention of a well-fixed acetabular component, rather than full acetabular revision, has multiple advantages, but questions have lingered regarding the clinical success and prosthetic survivorship following this procedure. We examined the impact of acetabular component position, polyethylene ty...
متن کاملBone grafts, bone graft extenders, substitutes and enhancers for acetabular reconstruction in revision total hip arthroplasty
Acetabular bone loss is a relevant concern for surgeons dealing with a failed total hip arthroplasty.Since the femoral head is no longer available, allografts represent the first choice for most reconstructive solutions, either as a structural buttress or impacted bone chips.Even though fresh-frozen bone is firmly recommended for structural grafts, freeze-dried and/or irradiated bone may be use...
