[Usefulness of HA+beta-TCP in bone defects repair during revision hip and knee arthroplasty].

Background: Bone deficiency can present a surgical challenge during revision total hip and knee arthroplasty. The amount of bone grafts available for surgical purposes is insufficient. Synthetic bone substitutes can eliminate the risk of infection transmission.

[Total hip arthroplasty after previous support proximal femoral osteotomy].

Clinical outcome and technical difficulties observed after total hip arthroplasty (THA) subsequent to support proximal femur osteotomy were studied in 6 total hip arthroplasties. 6 patients were follow up at an average 6.2 years after THA.

[Scorpio TS prosthesis in severe deformity and revision knee arthroplasty--preliminary report].

Authors present early results of Scorpio TS prosthesis in primary and revision total knee arthoplasty due to aseptic and septic loosening. 26 arthroplasties were performed on 25 patients. There were 19 women and 6 men of age from 37 to 80 (average 68.

[Modular short-stem prosthesis in total hip arthroplasty--preliminary report].

Total hip arthroplasty has become one of the most succesful procedure in orthopaedic surgery. More and more active, young patients undergo primary hip replacement. Bone stock preservation is crucial when performing THR in this group of patients.
