Is unilateral transverse process-pedicle percutaneous kyphoplasty a better choice for osteoporotic thoracolumbar fractures in the old patients?

Abstract Background A few reports have shown that unilateral transverse process-pedicle percutaneous kyphoplasty is a good choice for patients with osteoporotic vertebral compression fracture (OVCF). However, this issue remains controversial and the related comprehensive research was lacked. Methods retrospective study conducted on receiving PKP surgery OVCF. Patients were divided into three groups according to surgical approach. Symptom radiographical evaluation performed preoperatively, 1-month postoperatively, 1-year postoperatively follow-ups. And follow-ups repeated every year. Visual Analogue Scale Score (VAS), Oswestry Disability Index (ODI) scores, anterior height, coronal Cobb angle sagittal determined compared among groups. Results Totally 447 included an average age of 76.6 ± 7.2 years old. UTP showed significantly shorter duration (p < 0.001), lower cement volume 0.001) but higher leakage proportion = 0.044). No significant statistical difference found in terms improvement rates Besides, it notable observed group, about 4°coronal correction after PKP. Conclusion UTTP could achieve similar symptoms relief kyphosis as BTP had time less radio exposure than PKP, risk bilaterally distribution It seemed be better In addition, we especially fit OVCF asymmetrical compression.
