脊椎圧迫骨折の保存療法後に新たな圧迫骨折が生じる因子の解析

Risk Factors for a New Fracture after Conservative Treatment of an Osteoporotic Vertebral Fracture

　骨粗鬆性脊椎圧迫骨折の保存療法後に，新規圧迫骨折を生じさせる因子について検討した．初回受傷機転が非転倒であること，損傷椎体に後壁損傷を認めること，ビスフォスフォネート製剤の服用をしないことが新たな圧迫骨折発生の危険因子と考えられた．

　We analyzed 38 cases of osteoporotic vertebral fractures to identify risk factors for a new fracture after conservative treatment, and the following risk factors were identified：the first fracture was not the result of trauma, the posterior wall of the vertebral body was damaged, and absence of antiresorptive therapy.
