OBJECTIVE: To evaluate the efficacy and safety of percutaneous balloon kyphoplasty as a new therapy for patients with painful osteoporotic vertebral compressive fractures of the lumbar and thoracic spine.
METHODS: A retrospective analysis was conducted in 38 consecutive patients (28 females, 10 males), whose ages ranged from 56 to 82 years (mean age 72 years). The symptom- and sign-positive spinal segment was identified by MRI. The time between onset of symptoms and surgical intervention ranged from 2 days to 1 year. 62 segments (36 thoracic, 26 lumbar) were treated in this cohort. The pain score estimated by Visual Analog Scale and activity degree were assessed immediately after operation and at 1-, 6-, and 12-month postoperative follow-up. Preoperative and postoperative anterior, midline vertebral heights in fractured vertebrae were measured on lateral radiographs to evaluate the effect of the procedure.
RESULTS: The method achieved a swift pain relief associated with an evidently increased weight-bearing ability. The pain score was reduced from 8.2 to 2.4 points. The anterior and midline vertebral heights in 62 fractured vertebral bodies increased up to 82.76%+/-26.84%, 88.82%+/-21.75% and the wedge decreased from 15 to 8 degrees. This effect persisted at least over a period of two years. The procedure did not induce narrowing of the spinal canal and no severe complications occurred.
CONCLUSIONS: Balloon kyphoplasty can result in immediate clinical improvement of mobility and pain relief, increase vertebral body height, and quickly return patient's activity. The short-term results are approved excellent, and the long-term results need further judgment.
