 INTRODUCTION:Japan has many patients with osteoporosis;however, only about one-fifth of these patients receive treatment. Although some treatment guidelines exist for osteoporosis, the number of newly diagnosed patients with osteoporotic compression fractures is increasing and protocols for treatment of osteoporotic compression fractures vary from one hospital to another. This study aims to investigate the availability of early balloon kyphoplasty(BKP)in relation to our treatment strategy for osteoporotic compression fractures.

 METHODS:In our hospital, patients diagnosed with osteoporotic compression fractures were treated conservatively with a corset and rehabilitation. In cases where pain was prolonged and computed tomography(CT)imaging revealed formation of a cavity, we performed BKP. We divided the patients admitted between April 2016 and December 2016 with osteoporotic compression fractures into 2 groups, based on whether they received conservative treatment or BKP. We assessed the patients' age, fracture site, CT and MRI findings, bone density, Numerical Rating Scale(NRS), duration of hospital stay, and outcomes.

 RESULTS:In the BKP group, the number of Th12 and L1 compression fractures was higher than fractures to other vertebral bodies. No difference was observed in bone density, improvement of NRS, and outcomes between groups. CT cavity signs were more frequently observed in the BKP group than in the conservative group.

 CONCLUSIONS:This study establishes a correlation between the appearance of CT cavity sign and prolonged pain, which increases the likelihood of a patient undergoing BKP. The CT cavity sign and prolonged pain could be indicators of pre-stage pseudoarthrosis. BKP performed in the early stages of a fracture is safe and does not result in complications. However, BKP should be performed according to appropriate indications, including delayed neurological deficit, pain, and reduced bone adhesion.
