| Abstract |
Objective
Osteoporotic vertebral compression fracture (OVCF) in elderly patients is one of the leading causes of mortality and morbidity. Recently, bilateral percutaneous kyphoplasty (PKP) has been routinely performed to treat OVCFs that are not responsive to conservative treatment. The objective of this study was to determine the safety and effectiveness of PKP via unipedicular approach in elderly patients for OVCFs.
Methods
One hundred thirty two OVCFs of 115 patients (older than 65 years) were treated by unilateral PKP between January 2009 and December 2013. These patients underwent 115 operations to treat 132 vertebral compression fractures between T8 and L4. Clinical outcomes were determined by comparing preoperative and postoperative data based on patient-reported pain scale index (visual analogue score, VAS). Radiographs were assessed to determine the kyphotic angle of fracture body, vertebral height restoration and local kyphosis correction.
Results
Mean length of follow-up was at least one year. Obvious pain relief and functional recovery were obtained in all patients within 48 hours after PKP. The mean VAS scores for back pain were 8.6±1.6 on admission and 3.4±1.3 at last follow up (p<0.05). The kyphotic angle and the height of the fractured vertebrae were significantly improved after PKP (p<0.05). The mean operation time was 34.3±4.3 minutes per level. No adverse medical or serious procedural complication was observed.
Conclusion
Unilateral PKP markedly improved symptoms and restored the kyphotic angle and vertebral heights. Therefore, PKP via unipedicular approach in elderly patients for OVCFs is an effective and safe procedure with short operation time and low radiation exposure. |
