Purpose : The purpose of this study was to evaluate the functional outcomes of periacetabular malignant bone tumors treated by internal pelvectomy without reconstruction.
Materials & Methods : Between January 1996 and December 2005, eight patients with primary malignant or metastatic periacetabular bone tumors were treated by internal pelvectomy without reconstruction. There were 6 men and 2 women. Mean age was 42 years old. There were 3 osteosarcomas, 3 chondrosarcomas and 2 metastatic carcinomas. The type of pelvic resections were 6 type I+II+III, 1 type I+II and 1 type II+II resection. The functional outcomes were evaluated with ISOLS revised criteria. The follow up period ranged from 6 to 84 months.
Results : At last follow up, 5 patients showed CDF, 2 patients, AWD and the remained 1, DOD. The mean functional score for pain, functional activity, emotional acceptance, use of external support, walking ability and gait were 4.9, 2.9, 2.9, 1.5, 2.3 and 2.5 respectively. The total functional score ranged from 37% to 70%(average: 56%). There were three temporary
nerve palsies.
Conclusion : The internal pelvectomy without reconstruction for selective difficult periacetabular malignant tumors could be a viable option with fewer complications and fair functional outcomes.
