The Usefulness of Bone Scan in the Osteoporotic Vertebral Compression Fracture Patients Treated With Kyphoplasty / 대한척추외과학회지

ABSTRACT

STUDY DESIGN: Retrospective study. OBJECTIVES: To compare the clinical results of kyphoplasty between osteoporotic patients with compression fractures and rib hot uptake on bone scan and patients without rib hot uptake. SUMMARY OF LITERATURE REVIEW The incidence of osteoporotic rib fractures is 0.3% in postmenopausal women. MATERIALS AND METHODS: Between July 2005 and July 2006, 72 kyphoplasties for osteoporotic vertebral compression fractures were performed, and all patients had a bone scan study. On bone scan study, 41 patients (57.7%) had hot uptake in their ribs. Results were assessed by visual analog scale (VAS). RESULTS: The incidence of hot uptake was 67.8% in thoracic fractures, 40.0% in lumbar fractures, and 72.7% in thoracolumbar fractures. Hot uptake was significantly more common with thoracic and thoracolumbar fractures than with lumbar fractures (p0.05). CONCLUSIONS: Thoracic and multiple osteoporotic compression fractures are often accompanied by rib fractures. Bone scan is a useful tool to detect rib fractures and predict the prognosis of kyphoplasty.
