Abstract:
Clinical data of twenty-six patients with primary tumors involving hip ioint treated surgically in Renmin Hospital of Wuhan University between March 1999 and May 2005 were retrospectively analyzed.The diagnosis of all patients was confirmed by pathohistology.There were 3 cases of chondrosarcomas.6 osteosarcomas,1 synovial sarcoma,14 giant cell tumors and 2 aneurysmal bone cysts.Seventeen cases were treated with custom-made total hip replacement prosthesis,7 with custom-made dipolar femoral head prostheses and 2 with saddle prostheses.They were followed up for 18 months to 6 years with an average of 4 years and 3 monts.Local relapse rate and final limb salvage rate was 40%and 60% in 10 patients with malignant bone tumors:125%and 875%in 16 patients with low-grade malignant bone tumors.According to Enneking(MSTS)evaluation criteria.the average score was 19 with an excellent and good rate of 76.9%.Custom-made artificial hip prosthesis is a satisfactory method in limb salvage operations for patients with malignant or low-grade malignant bone tumors jn hip joint.
