LES RESECTIONS AVEC CONSERVATION DU MEMBRE INFERIEUR DANS LE CHONDROSARCOME DU BASSIN

Abstract

Twenty-seven chondrosarcomata of the pelvis were treated by local resection with preservation of the limb. Twenty-two were grade I or II, and 5 were grade III or IV. Attention is drawn to the importance of tomodensitometry in assessing the extent of the tumor before operation. An en bloc resection was well wide of the tumour in 16 cases, close to the tumour in 10 cases and involved the tumour in one case. Post-operative complications were varied. There were 6 nerve paralyses after iliac resection, 3 cases of sepsis after resection of the anterior part of the pelvic ring, and 3 cases of sepsis and 2 vascular complications after peri-acetabular resections. The average follow-up was 5 years. Three had metastases and three had local recurrences, one of whom died later from pulmonary metastases. No local recuRrence was seen in cases with wide resection. The functional results were satisfactory in 6 out of 7 partial resections of the ilium and in 4 out of 5 resections of the anterior part of the pelvic ring. They were only fair after peri-acetabular resections and complete resections of the ilium. After peri-acetabular resections, the results were about the same after ilio-femoral arthrodesis or Girdlestone operations. It is not appropriate to reconstruct the pelvic ring after resection limited to the anterior part of the pelvis but it is indicated after resections of the whole of the ilium, particularly in children to avoid shortening of the limb with pelvic shift
