[Experience with modular system tumor prostheses].

Authors elaborated a modular tumor prosthesis by the use of which the bone segment lost after the resection of hip, femur, knee and proximal tibial tumors can be supplemented in the desired measure. The components of the prosthesis set and the field of its use are described. In the last one and half year modular tumor prostheses were inserted in 10 patients: in 6 primary bone tumors and 4 solitary metastases. One shoulder, 5 hip, 3 stiff knee and 1 tibia diaphysis supplementing modular prostheses were inserted. In spite of 2 complications the initial experiences are encouraging, and in adequate indication the possibility of retaining limb and articular function beside good functional results is given.
