[Recostruction of Extensive Acetabular Defects by Bioactive Glass Ceramics in Re-operations of Total Endoprostheses.].
- Ortopedická klinika FN, Hradec Králové
The authors made 37 revisions on account of aseptic loosening of total endoprostheses of the hip joint using bioactive glass ceramics BAS-0 of Lasak Co. Prague. For reconstruction of large defects of the acetabulum they used a combination of different types of anti-protrusion metal baskets and granules from this material. In some instances the glass ceramic material was combined with autologous spongiosa. The longest follow-up period is over 4 years. In no instance loosening of the glass ceramic material occurred or its expulsion. All reconstructed sockets of hip joints were burdened by the patients from the third month after surgery. Harris Hip Score before operation was on average 52. During the last checkups of the patients it reached the level of 86. The authors mention complications associated with the procedure. The advantages and disadvantages of the procedure are discussed. Key words: bioactive glass ceramics, reconstruction of acetabular defect, aseptic loosening of endoprosthesis.
