Abstract

PURPOSE
This study was undertaken to evaluate the long term survival of pelvic chondrosarcomas, optimal reconstructive procedures and functional results. MATERIAL AND METHODS: We studied 14 primary and 3 secondary cases of pelvic chondrosarcomas. All patients had an internal pelvectomy. Resection types were the iliac wing in 4, periacetabular in 9, and there were 4 in the pubic area. Reconstructive types were: no reconstruction in 6, spacer and bone graft in 2, heat treated autogenous bone-total hip replacement arthroplasty (THRA) composite in 4, limited fusion in 2 and the remaining 3 patients had a saddle prosthesis.
RESULTS
An actual and continuous disease free survival rate was 93/87% at 130 months. The overall functional score was 22.4. The score for four cases of iliac resection was 27.7, in nine cases of periacetabular it was 18.6, and in four cases of pubic lesion it was 25.5. Associated complications were dislocation of THRA in one case, two cases of infection, sciatic nerve palsy in one and one case of skin necrosis that was secondary to radiation.
CONCLUSION
Chondrosarcoma of pelvis shows an excellent long term survival rate. Attempts at pseudoarthrosis rather than anatomical reconstruction in periacetabular resections with massive soft tissue damage may reduce complications and their functional results are acceptable.
