Surgical Treatment of Bone Tumors Arising from Pelvic Ring

Summary

Six patients with periacetabular pelvic tumors were treated with a new type of constrained total hip replacement without reconstruction of pelvic continuity later wide resection. Five of six patients were able to walk with the supporting aids without pain after a follow-up of 6 months to 3 years. There was one local recurrence and one metastasis. No prosthetic failure and symptomatic loosening were found. Pelvic tumors away from the acetabulum were resected with wide margins and had no local recurrence. They had almost normal function. In sacral tumors (11 cases), there were two local recurrences and two deep infections. The preservation of the S₂ nerve root appears to be adequate for normal control bladder and bowel functions. Moreover, stability of the spinal column can be obtained with complete preservation of the body of the S₁ vertebra.
