Abstract

Objective Clinical comparative study of percutaneous kyphoplasty in treatment of acute and chronic and nonunion osteoporotic vertebral compression fractures and the operative opportunity. Methods Totally 91 elderly with osteoporotic thoracolumbar vertebral compression fractures were treated by PKP and divided into acute and chronic and nonunion fracture group, acute fracture group 59 patients,chronic and nonunion fracture group 32 patients, the surgical outcomes were evaluated by using visual analogue scale(VAS), Oswestry disability index(ODI)system, kyphosis angle(cobb method), the height of vertebrae body before and after 1 week, 3 months after surgery. Results All patients had rapid and significant improvement in back pain following percutaneous kyphoplasty.and followed 6- 12 and 3 months after surgery(P 0.05). The kyphosis angle(cobb method), the height of vertebrae body were improved significantly at 1 week and 3 months after surgery(P<0.05), and the acute fracture group was improved significantly than the chronic and nonunion fracture group(P<0.05). Conclusion The curative effect of percutaneous kyphoplasty for the treatment of acute painful osteoporotic vertebral compression fracture(POVCFs) and chronic and nonunion POVCFs was satisfactory, the kyphosis angle(cobb method), the height of vertebrae body for the acute fracture group were superior to than the chronic and nonunion fracture group(P< 0.05). Key words: Osteoporotic vertebral compressive fracture; Percutaneous kyphoplasty; Chronic; Nonunion; Operative opportunity
