title: Limb salvage surgery in bone tumour with modular endoprosthesis.
abstract: Thirty-three patients with bone tumours were treated by resection of the growth and reconstruction with a Kotz modular endoprosthesis. The average follow-up was for 50 months, ranging from 14 to 79 months. At the last review, 12 patients (36%) had died due to the tumour and 9 others (27%) had metastases. All 4 patients with proximal tibial reconstruction had poor functional results, due to an extension lag or to knee stiffness. Four of the six tumours of the proximal femur were complicated by local recurrence or dislocation of the hip, and had poor or fair functional results. Of the patients with distal femoral reconstruction, 17 out of 22 had excellent or good functional results. Reconstruction with a modular prosthesis after resection of a tumour gives excellent or good functional results in more than three-fourths of the cases of distal femur reconstruction, but it should be used with caution in the proximal tibia and proximal femur.
