Abstract

PURPOSE: To evaluate the result of percutaneous vertebroplasty in the treatment of osteorporotic stable burst fracture that has not neurologic symptom.
MATERIALS AND METHODS
A retrospective review was conducted in 37 vertebrae of 33 patinets with osteoporotic stable burst fracrure treated by percutaneous vertebroplasty from February 2000 to May 2003. Stable burst fracture was classified by McAfee. The operation was performed in the patient without neurologic symptom, BMD T-score was below -2.5 and hot uptake was seen in (99m)Tc bone scan. The operation was held from post-traumatic 7 to 32 days, average 17 days. Follow up period was from 5 months to 38 months, average 11 months. The result of the treatment was assesed by clinical finding (pain scale and work status by Denis) and radiologic findings (percentage height restored and change of kyphotic angle).
RESULTS
In clinical assessment, 27 had a satisfactory pain scale below the P3, 25 had a satisfactory work status below the W3. In the radiologic findings, percentage height restore was increased from 0% to 62%, average 23.3%. The preop. kyphotic angle was from -20 degree to 42 degree, average 8.9 degree. The postop. kyphotic angle was from -20 to 42 degree, average 6.5 degree. The kyphotic angle was decreased average 2.4 degree after operation.
CONCLUSION
Treatment of osteoporotic stable burst fracture with percutaneous vertebroplasty is the minimal invasive treatment that has satisfactory pain relief and reduction of fracture.
