Radiographic Comparison of Stable Burst Fractures with Compression Fractures in Thoracolumbar Spine / 대한척추외과학회지

ABSTRACT

STUDY DESIGN: A retrospective study was designed to evaluate the radiographic diagnostic method to detect any abnormal findings and differentiate stable burst fractures with compression fractures at thoracolumbar spine. OBJECTIVES: To evaluate diagnostic sensitivity of radiographic analysis and confirm the effectiveness of the radiographic diagnostic methods to differentiate stable burst fractures with pure compression fractures. SUMMARY OF BACKGROUND DATA A data showed that the diagnostic sensitivity using radiographic analysis was 83%. The greater sensitivity was obtained at high posterior superior vertebral angle and PSVA/PIVA > 1.3. MATERIALS AND METHODS: Thirty-one patients with thoracolumbar spine fractures were evaluate to differentiate stable burst fractures with pure compression fractures. All patients were taken X-ray and CT. The PSVA(Posterior superior vertebral angle), PIVA(Posterior inferior vertebral angle), PSVA/PIVA were checked using lateral plain radiographs during follow-up period, and the final data was analysed using radiological & statistical methods. RESULTS: Middle column failure of stable burst fractures was greatly observed at high PSVA(especially >100degree) and high PSVA/PIVA ratio(> 1.3). CONCLUSION: The radiographic analysis using PSVA(Posterior superior vertebral angle), PIVA(Posterior inferior vertebral angle), PSVA/PIVA might be the one of useful methods to differentiate stable burst fractures with pure compression fractures at thoracolumbar spine during follow-up period.
