[Percutaneous vertebroplasty for vertebral osteoporotic fractures: long term analysis].

OBJECTIVE: To assess the long-term efficacy of percutaneous vertebroplasty for the treatment of pain resulting from osteoporotic vertebral fractures. METHOD: 26 percutaneous vertebroplasty procedures were performed for osteoporotic vertebral fractures in 15 patients during the period between July 2001 and May 2004. Before and after the procedure, a 10-point scale of pain was obtained. These scale was repeated at long-term follow up in two different moments after the procedure with one year interval. During these moments, the satisfaction, ambulation and ability to perform activities of daily living (five-point scale) were also analyzed. RESULTS: The majority of patients (n=13) presented the 10-point pain scale between 8 and 10 before the percutaneous vertebroplasty. After the procedure, there was important improve of the pain, and nine patients presented zero point-scale and three patients between 1 and 4 (p<0.001). At long-term follow up with one year interval, there was no significant difference between the pain scale, the ambulation and the ability to perform activities of daily living. Fourteen patients reported a future willingness to undergo the procedure for treatment in case of a new compression fracture. CONCLUSION: Percutaneous vertebroplasty can be a useful procedure for the treatment of pain and disability after secondary osteoporotic vertebral fractures with durable results in selected patients.
