| PURPOSE To evaluate safety and effectiveness of performance of percutaneous kyphoplasty(PKP) in patients with osteolytic tumor of vertebrae.METHODS Since 2004,16 cases with 25 vertebral body(9 female cases with 15 vertebrae and 7 male cases with 10 vertebrae) underwent PKP under the monitoring of C-arm x-ray machine were observed.The vertebrae segment was from T6 to L5.In these cases,there are 11 cases of spinal metastases with 17 vertebrae,4 cases of hemangioma with 7 vertebrae,and 1 cases of multiple myeloma with 1 vertebra.All the patients had a refractoriness back pain,without symptom of nervous lesion.CT and MRI showed osteolytic changes in the vertebrae.Patients were followed up by 6 months to 4 years,a average of 18 months.The analgesic effect after operation were observed.RESULTS The total 16 operations were done successfully.Cement leakage not leading to any complications occurred in 1 vertebrai segmental vessel and 1 vertebral bodies.The X-ray showed that all of the treated vertebrae were filled well by cement.All patients got a conspicuous pain relief in 24 hours after operation,and no spinal injury or compression was found.At 1 year follow up showed that no pain recidivism in the treated vertebrae.CONCLUSION PKP is one of the efficacious way to alleviate pain of vertebral metastases and hemangioma.It can reinforce the stability of involved vertebral body. |
