Endoprostheses in Children — First Results
The first good results achieved in grown-up patients with tumor endoprostheses for the lower extremity in cases of primary bone tumors, a method taken up in Vienna in 1976, have raised the issue of implanting prostheses also in children. Initially almost grown children were implanted with a slightly oversized endoprosthesis instead of a rotationplasty, the risk of a small degree of leg shortening at the end of the growth period being taken into account. The use of a modular system made later extensions easy through simple prosthesis exchange. Thus, it was possible to effect length corrections by simply decoupling a resection part and replacing it with a longer one. The good results achieved in adolescent patients and children who were still growing as well as the need to make more extensions in smaller sections gave rise to the development of a growth module to go along with the modular femur tibia resection system (KMFTR).
