Clinical Results following Reconstructive Methods in Pelvic Tumor / 대한정형외과학회잡지

ABSTRACT

PURPOSE: This study evaluated the results of periacetabular resections in patients with pelvic tumors according to the reconstructive methods. MATERIALS AND METHODS: Twenty-seven patients, who underwent a periacetabular resection with a minimum one year follow up were eligible for this study. There were 20 primary malignant bone tumors, three benign aggressive tumors, three metastatic tumors and one soft tissue sarcoma. According to Enneking's criteria, a type I+II resection was performed in seven patients, type II+III in 17, and type I+II+III in three. The type of reconstructions used were heat treated autogenous bone-THA composite (APC) in 15, a saddle prosthesis in 6, arthrodesis in 2, and a flail hip in 4 patients. The MSTS functional scores and complications according to the type of reconstruction were evaluated. RESULTS: Eleven (46%) of the 27 patients were in the disease free state and 7 (26%) patients showed local recurrences. Eleven (73%) out of 15 patients with APC and 2 (33%) out of 6 patients with a saddle prosthesis had complications including infections, dislocations and loosening. The final average MSTS score was 19.6 (65%) and all reconstructive methods produced similar functional results. CONCLUSION: Reconstructions of the acetabulum with a prosthesis after a periacetabular resection had a relatively high rate of complications. A flail hip might be one suitable reconstructive options after a periacetabular resection.
