| Abstract |
Objective
Osteoporotic vertebral compression fractures (VCF) are associated with pain, disability, high dosage of narcotic analgesic, and longterm
bedridden state. Vertebroplasty and kyphoplasty, both are effective methods of pain relief and recovery of patient's social function.
It has debates on the effectiveness until nowdays, but there is rare report about improvement of life expectancy for old aged patients with VCF
after vertebroplasty and kyphoplasty. We analyzed the mortality rate for vertebral compression fracture patients.
Methods
We investigated patients over the age of 75 with osteoporotic VCF, whose database was obtained from medical record and picture
archiving communication system (PACS). Information including comorbidity, diagnosis, treatment were collected. Survival period was confirmed
through medical record, governmental statistics of mortality, and follow-up. We excluded the patients with trauma such as fall-down, traffic
accident, with secondary osteoporotic VCF, and with younger than 75. Exact Fisher tests, Mann-Whitney tests, and proportional hazards regression
modes with Kaplan-Meier plots were used to compare the effectiveness between the patients who underwent vertebroplasty and kyphoplasty
and who was treated conservatively.
Results
A total of 151 patients with osteoporotic VCF were identified, including 45 vertebroplasty and kyphoplasty patients. There was no
significant differences in the sex, age, diabetes mellitus, heart disease, and pulmonary disease except renal disease and number of fracture.
Adjusting this covariants including renal disease and number of fracture, vertebroplasty and kyphoplasty prolonged the mean survival periods by 403
days than non-surgical methods.
Conclusion
This report suggests that vertebroplasty and kyphoplasty are effective methods for patients with osteoporotic VCF to improve
a mean survival periods than non-surgical methods. |
