Abstract:
Objective To evaluate the feasibility and therapeutic effect of kyphoplasty in treating severe osteoporotic vertebral compressive fractures. Methods Thirty-five patients (48 vertebral bodies) with severe osteoporotic compressive fractures were included. There were 33 females and 2 males with the mean age of 74.2 years. The average compressive rate of the affected vertebral bodies was 77.0%. The thoracolumbar vertebrae were treated with kyphoplasties. Percutaneous puncture direction was adjusted according to compressive rate and shape of the vertebral bodies. The inflatable bone tamp was inserted into the fractured vertebral body. The balloon was inflated with low pressure and dilate-relieve-dilate method was applied. The balloon was deflated and withdrawn, leaving a cavity within the vertebral body, which then fulfilled with visualized bone cement. Preoperative and postoperative symptom level, complications and radiographic findings were recorded. Results All 35 patients tolerated procedure well. The mean heights of the anterior, mid and posterior vertebral body had improved from (0.8±0.1) cm, (0.8±0.2) cm, (2.1 ±0.8) cm preoperatively to (1.2±0.3) cm, (1.3±0.2) cm, (2.3±1.0) cm respectively after operation (P ＜0.05). There was significance difference between preoperative and postoperative heights of the anterior and mid vertebral body. The mean kyphosis was improved from 28.2°±5.2° before operation to 19.1°±4.9° after operation. Conclusion Kyphoplasty is feasible and effective for severe osteoporotic vertebral compressive fractures.
