Role of Supine and Standing Radiography in Vertebroplasty for Osteoporotic Compression Fractures"

Objective: To confirm the benefits of vertebroplasty (VP) in selected patients with acute vertebral compression fracture (VCF) and analyze whether the study of a weight dynamic plain lateral radiograph would help in making decisions to perform VP. Using retrospective analysis, we aimed to determine the radiological characteristics of patients benefiting from VP.Methods: Data were collected from 54 patients (age, 56-97 years) diagnosed with osteoporosis and compression fractures between December 2013 and January 2018. Each patient was hospitalized with ≥2 weeks of absolute bed rest (ABR) and treated for osteoporosis. Plain lateral supine radiography of the fractured spine was performed prior to diagnosis, and both supine and standing spinal radiographs were taken 1 and 2 weeks after ABR. Patients were categorized into the VP and non-VP groups 2 weeks after ABR.Results: Although patients with worse pain and functional progress were selected to undergo VP, patients in the VP group presented better outcomes in the fourth week of evaluation than those in the non-VP group. In a retrospective analysis of the radiographic study, changes in the compression rate between supine and standing (weight-bearing) X-rays (ΔCR), showed a statistically significant correlation with the patient’s outcome in the second week.Conclusion: VP was found to be an effective management option for patients with VCF. A weightbearing radiographic study of VCFs provided valuable information on patient selection for VP. Therefore, patient selection based on subjective surveys and radiological studies to determine the benefits of VP could be a beneficial management strategy.
